So what about the Norwegian ice breaker that got stuck this year? 1924 there was no ice at all north of Svalbard, what kind of fee do we have to pay for buying better and more ice for the polar bears? We need more CO2, not less, the plant life is at a starving level.

No matter how charming the speaker is or how informative the talk is, most of the information worth sharing is lost if we can't see what the speaker is speaking about. This makes what might have been a valuable talk almost worthless in its video form. I'm sure you would agree that is a horrendous waste-even of your own time and effort, as the video editors. In most cases, the speakers are not up there to be featured in their own fabulous close-ups; they want to communicate something, and they've designed visual aids to help them communicate their important ideas. Please do them and your entire audience a favor by helping them out with that. Thanks so much! Respectfully.
@Jon Smith Many variations on that. Life is a journey, not a destination. Religion is a journey, not a destination. Learning had better be a journey for me. I'm 71 years old and just finishing my master's degree. For some, the people who need the degree to get a raise or a certain promotion, it is a destination. But I think making it a destination does undermine the process learning. People tell me sometimes, you're never too old. I tell them, on the other hand, maybe this is the right time. It could be.
great and wonderful information. If only we could see those slides !!! We CANNOT GO TO THE ARCTIC, WE MISSED THE TED TALK ALIVE. AND NOW WE MISSED THE SELF EXPLANATORY SLIDES . STILL THANK YOU FOR THIS GREAT INFORMATION
Sea Ice does not make sea level rise. Ice is frozen water so when ice melts the sea level does not rise. If you doubt that simple example try the experiment for yourself in your own kitchen. Fill a jug with water and ice and mark the water level on the side of the Jug, Let the jug sit until th eice melts and the water level will be at the same mark as before. So all the talk and talk is baseless it is really meant to mislead you to panic and somebody is making money so follow the money?
when the newest largest Norwegian ice breaker set out recently for the North Pole it ran into ice much thicker than expected , was damaged and had to return to Norway . I think the takeaway is that satellite estimates of ice thickness are not to be relied upon . also , there is significant yearly variation . ice cover is greatly affected by wind speed and direction . as of 2021 there is no statistical trend in arctic sea ice for the last 15 years .
Superb! Such a fluent and easily comprehensible presentation of a complex set of topics! My thanks to David Barber for choosing to do this as well as to TED and the University of Manitoba for the platform. However, as to the video itself, I join others in expressing that the slides were NOT clearly shown. Perhaps the screen can be split into two showing the presenter on one side and the slides on the other?
It was a lot warmer in the last Interglacial Period, and the Polar Bears made it through it fine. Who told you CO2 drives temperature? It never has in the past, (see Vostok ice core data). A warming during this interglacial period is not only possible, but likely as past interglacial periods have all been much warmer than this one, (Coolest interglacial in last 1/2 million years), we could warm by 4-6 degrees C. The last interglacial was 4 degrees C warmer than we are, and the oceans were 20' higher than now.
Real scientists have been studying the record of the planet's climate, using ice cores from Antarctica, among other places. You should learn what research is and how to do it. Search for Vostok ice core data graphs. Read the pear reviewed articles about their findings. You have only given us your title, "Dr. Climate Denier", and your name, Mr. "Duhhh". With all your studying of a picture of one area, over a relatively short time period of time, when do you predict the next Glaciation will begin? I'm guessing it will start sometime between now, and 10,000yrs from now.

why would your obviously important information to civilization not be shown in the video? did someone not have instructions to point the camera at your images on the screen?
Excellent talk presenting the facts. Always great (though spooky) to hear from someone who has worked in the Arctic region and speaks from first hand experience and observation.
I come from the future, 2019. We discovered that we didn't really know as much as we thought we did about arctic ice. Turns out it was just in a cycle and now we've got more than we used to. It turned out to be Much Ado About Nothing.
Dr. Barber has an appealing avuncular style. His presentation was in 2014, and describes an expedition in 2009. It is now 2019 so that is 10 years later. Has all the Arctic ice now gone? Are the Polar Bears gone? The Arctic is a relatively small conglomerate of floating ice chunks. Why no mention of the Antarctic which holds 90% of the world's fresh water as ice.
Too bad this guy is not familiar with history. If he was, he would know that around the year 1360, a group of Vikings from Denmark, led by Paul Knutson sailed into Hudson Bay and then up the river systems there, eventually reaching into what is now the state of Minnesota. They left a stone there that describes some of their exploits. The stone was discovered by a farmer and has since been named "The Kensington Rune Stone." It was thought to be a hoax for many years, but recent research has uncovered a document in the Danish archives that directs Paul Knutson to make the trip. Additionally, numerous swords and other Scandanavian artifacts have been unearthed by the plows of farmers throughout the region. You might ask what this has to do with sea ice etc. The facts are that back then, things were so warm that Vikings had made permanent settlements in Greenland, where they grew crops and thrived because of the warmth. They eventually had to abandon their settlements as the weather grew colder. It is still too cold to grow the kinds of crops that archaeology has shown them to have been raising during their time there. All of this shows us that alternations of cold and warm are the way of the planet, and that we out to simply adjust to the idea, rather be alarmed by it. For goodness sakes folks, we weven have fossil evidence that there have been tropical temperatures at the south pole in the distant past. Last but not least; CO2 is not poison, it's plant food. Don't let others do your thinking for you. Get out there and do your own research.
Fantastic text with beautiful info, great work im glad to have found it. Write more like this on youtube. much more! you are really talented, you should spread this exact text to as many places as possible, less work for you more joy for the lucky people who read it!
This was a great presentation. I really wish the TEDx producers would show the slide when the speaker is referring to it, rather than focusing on the speaker :/
It's 2019, 4 and 1/2 years since this was made. the ice on our north and south is growing. And, if it is too melt it would not be the first and it wont be the last. Polar bear population has increased since the recording of this.
He is right about the south pole and polar bears. The last three years have seen a drop in temperature which is due to passing the grand solar maximum; this trend should continue until about 2044. It will be a few years before we see a definite reforming of the Northern ice sheets due to natural fluctuations.
Greetings, Very easy to search the massive Jakobshaun Glacier in Greenland, because of it`s scientific importance it is referred to as "The Canary in the Coal Mine" of Glaciers and was receding at the alarming rate of 1.8 miles per year and a reduction in depth of 130 feet per annum --- HAS STOPPED and is now INCREASING at the same rate as it was receding over the last 2 years.This video is 4 1/2 years old and there have been massive freezing events in the past 3 years in Northern Europe and Greenland. In 19 zones in the arctic the number of polar bears recorded has increased by over 8,000 in ten years, i am pleased to report. Kindest Regards.
are we at the end of an ice age? will the world look like it did before the ice age if all the ice melts?It seem man cannot control the weather so wouldn't it be better to accept change.
Nope we are at the end of the warming period and ice age "coming" (ok can be between few months to few centuries lool... but coming... Big ice periods about 100000ans with a 15000-20000 warming period. We are at the end of the actual one! +variations of 400y, and this one is coming very soon! (Jupiter+saturn alignment starting 2019 ) Maybe the climate hoax on purpose to hide this reality and let the elites build their shelters and leave the rest of the world die on the surface! (with ice no food even if you manage to heat yourself)!
reference2me "t seem man cannot control the weather so wouldn't it be better to accept change." YES man can and has, and that is what climate change is, the manipulation and engineering of both weather and climate with technology.
haha, they probably thought they where going to get away with that fact in 2015 since back then most meida coverge was mocking all non mainstream(=political/commercial) views
Great informative, up-beat presentation. I love the part when he says that the Earth did not come with a "manual". So we have to trust our scientists and listen. Unfortunately there are a lot of people who troll on TH-cam for big oil. I just don't get it-how they can be so unconscionable?
Good for you if you want to believe people who got it wrong since 25 years my friend! There's science and there's scientist, you have to do the difference...
When the ocean is open enough, the resulting heating of the atmosphere over the Arctic ocean should become an area of rising air instead of falling air as it is classically. This should suck the climate zones northward and disrupt the major grain growing areas of the northern hemisphere. The polar jet stream should disappear and we might well have a two Hadley cell system in the northern hemisphere.
I have difficulty understanding what you are saying. With no ice there is no reflected summer heat, all you will have is refracted heat but a lot more of it will not be refracted, surely? If not refracted it will absorb at depth. Do you have any idea how much that will be? Also how have you managed to compute your thermohaline effect?
I hope only that this all not leads to stalling of wind because of less difference between equator and poles. All our windmills would have problems then delivering at the moment when we need them most.
1. A Reminder of basic Physics. Ice only contains salt if the ice water freezes too fast for the ice to reject the salt. So that rotten Ice.. would indicate a lower temp' at winter. 2. Water that distrupt the air above would lead the disruption. So the vortex should have been over water. Not it the continental US. Not to mention Canada. 3. The old Ice is there anymore. Same time- the old Ice is hazardous. Ok.
Nothing like an audio version of a potentially visual presentation, but then most TED talks are like this , aren't they? Oh David, BTW ,CO2 follows climate differential it does not create it.
johnnieo66 CO2 can follow climate diffs but it also can create climate diffs. In the case of CO2 follows climate diff, it boosts it if it is a positive diff.
Carlo Ammann Not sure what you mean. Yes, with science we can predict and calculate the changes in the earth’s orbit and tilt. We can also calculate the forcing from greenhouse gases.
@@davidjaglin5507 Moisture in the atmosphere is the biggest cause of the greenhouse effect Not CO2, this is just another scare mongering story, more polar bears than ever, just a tax ploy
Donald Morton You should look into the carbon and water cycles. Increased CO2 increases atm temp which makes the atm hold more moisture....which increases atm temp....
Very interesting presentation. I'd love to see a follow-up to see whether the issues mentioned have continued, increased, or decreased. Is there still a lot of "rotten" sea ice, and is it more than previously? For polar vortex, there was certainly a lot of attention at one point, but it seems to have disappeared from weather discussion. Is that because the effect is now routine, or because it has migrated to different parts of the world, or because 2014 was just one freak occurrence? What other new and surprising results have come from ongoing research?
I'm really glad that you have the job you do, that you have colleagues, and that you are somehow paid for your services. Those of us who find science valuable and believable, love having this data put in front of us.
But rather than float about dysfunctionally they would have better spending research time finding how much faster the taiga is growing in the much more favourable conditions.
I’d like to see a similar dissertation for Antarctica. I’m reading that though the sea ice there may be thinning the terrestrial ice is growing. My question is what effect this imbalance in weight distribution will have on the planet as a whole. He doesn’t mention the magnetic pole migration which appears to be speeding up and racing toward Siberia. A pole shift seems to be in progress. The earth’s EMF plays a big part in changing weather patterns as well. A grand solar minimum has also begun reducing the amount of energy reaching the earth leading to cooler temperatures as well as causing an increase in both volcanic and tectonic activity. CO2 concentrations is just one part of a very complex system
Immanuel Velikovsky had some interesting and scary things to say about crustal shifts which could occur as a result of a weight imbalance. Additionally, this presentation makes no mention of the now rapid migration of the magnetic North Pole. Changes are afoot
Our planet is a constantly changing environment. Thinking that a single place on the planet is going to have the same environment such as temperature or amount of ice, year after year is an erroneous supposition in and of itself. Even the magnetic poles and spin of the earth are changing. You can try to measure the conditions but the results don't really give us as much a conclusive value as some are suggesting. Think of the human body or financial investment. Past performances are not necessarily indicative of future results. I have no problem with people making predictions based on past performances, but we should never take them to the bank and God forbid, let politicians alter our economic future based on these type predictions.
@@randallsemrau7845 Whatever yield may be gained by an increased CO2 level will be more then wiped out by the increased frequency in heat waves, drought and flood. But of course you are more into misinformation then providing the whole story aren't you??
Myopic nonsense. Hello ? There is a much better indicator. It is called the Antarctic. Ice levels on land and sea have been slowly increasing. Where is his talk about that ? The north ice is on water and means that it overreacts like a hyper 3 year old in regards to small yearly temp increases and decreases. Look to the south for the truth.
There are no growing icecaps in the antarctic. The sea ice there is greater in the winter, but it is because of all the freshwater melting off of the continent that freezes faster than saltwater. The surface of the sea around Antarctica is diluting from the runoff of all the melting ice on land.
Due to the size of Antarctica and the circumpolar current both ocean and atmospheric there is an increase in snow well inland (was always in the models , in fact due to it's peculiarities Antarctica melt was not expected until next century), but happening much quicker due to the warmer oceans eating the ice away from underneath and allowing the great ice sheets to flow down to the ocean. It has also been far warmer in West Antarctica and the loss of land ice there is resulting in a rebound of the crust, this matters because it is a volcanic region (lots of volcano's on East and West Antarctica) and that rebound is altering the viscosity of the crust and mantle as pressure is being reduced on volcanic vents and magma channels meaning increasing volcanic activity as the magma plumes head crustward, this will just melt more ice. Tipping points are being approached all over the place
Frank Speaking yeah you’re right there are a lot of volcanoes, but only on the western side really. It doesn’t change the facts that the glaciers and ice caps in the southern region of this planet are indefinitely growing. New Zealand, the Andes, and Antarctica, all follow the same trend.
Wrong, the worlds tallest ACTIVE volcano is in East Antarctica - there are plenty of volcano's and active areas under East Antarctica, look it up. The thing is they tend to be well inland and as a result are covered by mile high ice sheets and actually in many cases provide under ice oasis with huge liquid lakes with life and a slow leakage of water along the bedrock
It is the trend over time as the ocean and atmosphere cycles do their magic, South America is actually facing future water issues as so many are dependant on meltwater from rapidly shrinking glaciers, watch and learn, one swallow does not spring make
What reduction of arctic sea ice ????? The arctic sea ice shelve has been ~ stable - summer and winter extent - since 2006, despite of all of the greeny propaganda to the contrary !
@@j_forfreedom45 - you mean the instruments that clearly show the thinning of the ice and the snow line retreat? I'm glad you accept satellite measurements, many deniers pretend they are not 'real' sources of data.
This TED talk occurred 7 years ago. Conditions in the world and the arctic are not the same. Watch another TH-cam lecture by another scientist Dr. Patrick Moore called Climate Realism where he talks about what was more current in the Arctic a year ago.
Latest modeling shows an ice free arctic projected for fall of 2022. This constitutes the first in a series of tipping points daisy-chained like dominoes. When the last domino falls... Well. The only complex life forms will be extremeophiles. There is no getting out of the way. There is no "turning this around". If the whole world dedicated it's efforts to conservation and amelioration perhaps we could slow it down a little, maybe give us another 100 years. That's not going to happen. Do you suppose the Creator will forgive us the destruction of Creation? Oh right, some of us are pre-forgiven, I forgot. /read sarcasm/ You can't build a society based on greed and ego and expect good results. See you on the other side. Be brave.
They use satellites to monitor and measure the ice. But he never explained how they measured it 1000 years ago. Where's the data, show me so l can make up my own mind. Sounds to me like you're fishing for funding. O.k. show me the data from the past 1000 years........... Still waiting......... Still waiting..... Oh I see, you have no data. Good by.
Ever wonder why Dr Barber and his ilk only focus on the Arctic while never mentioning the other polar region aka the Antarctic?? It's because ice has been increasing in that region which not so conveniently contradicts the narrative.
The valid information in this TEDx is directly proportional to the time spent looking at the screen. It would be great if he HONESTLY explained all the assumptions they use as foundations to their claims.
The effect of CO2 in the atmosphere is known science. Some things have been worked out not only in theory but confirmed by experiments. Oh and btw google what has happened to plankton.
Dan Kelly "Known science?" All "science" is is the practice of observation, collection, hypothesis, and testing of something. Saying it is a "known science" suggests you have no idea what you are talking about. Now, assuming I think I know what you meant to say, all (I repeat, ALL) predictions we have on what happens if we increase CO2 is purely theoretical, built on MANMADE MODELS that have so far been wrong. Every single prediction has been wrong! Let's take a look at Al Gore's famous hockey stick. During the Industrial Revolution, global temps WENT DOWN, not up. During the Great Deoression, global temps went up, not down. Hmm! During the WW2 era, global temps went down. Oops!
Ahh, come on. Your retort is an attempt at insult? So much for intellectual conversation or debate. But, I see it all the time. It's okay. When people don't understand enough to debate, they get into name-calling. I see where you are intellectually now. Thank you.
@Rick Torbet The effects of CO2 is well known and replicable in a laboratory, *IT IS NOT PURELY THEORETHICAL* The reason models are used, it is not exactly sure how much the earth climate sensitivity is but that it is undoubtedly resulting in increased global temperatures, that is observed facts. It would be a mystery if increased CO2 levels did not result in raised temperatures. The models are pretty accurate, don't know what you have looked at. CO2 is not the only factor that affects the temperature it acts like an amplifier, in the end it is about how much solar irradiance that reach earth and that varies but CO2 is undoubtedly increasing the temperature from what it would have been without it. Good example look at the moon.... The fact that not every year is the warmest ever is of course a good thing, meaning of course some years temperatures goes down but the trend line is clear, steady rising temperatures. Al Gore is not a climate scientist he is a polititian, not a great source for facts, he did get some things wrong but reached he'´s objective. What the alternative to "Man made models" is I do not know, stone tablets from God??
Umm NO. There is no evidence that increased temperatures is "undoubtedly resulting" from increased CO2. We really don't have any evidence in increased global temperatures at all. We see slight increases in some parts of the earth, and slight decreases in other parts of the earth. That suggests BALANCE, no imbalance. It doesn't help that our "global warming" data points have been altered. Some have been removed from the data in colder regions to help skew the data to make it look like the whole earth is warming. Again, you are drinking the Kool-Aid!! "but CO2 is UNDOUBTEDLY increasing the temperature..." Again, there is no proof that CO2 is the cause of temperature increases, if we even have increases. "The trend line is clear, steady rising temperatures." That would make sense, since every single "old earth" scientist believes we are coming out of an ice age. One thing people fail to recognize is if CO2 in the atmosphere prevents the sun's energy from escaping (warming) it should also prevent the sun's energy from penetrating (cooling). Here are the REAL FACTS. (1) The earth may or may not be warming, as data points have been removed to purposely skew the observations. (2) Plants are starving for CO2, and the limiting factor in photosynthesis and plant growth is not enough CO2. Plants remove CO2 from the atmosphere. If Democrats really wanted to stop increases in CO2, why do they make it impossible for Californians to grow grass? ZERO-SCAPING IS BAD !!! (3) Concrete production creates far more CO2 than an entire army of tanks. Why does no one ask that we go back to dirt roads? (4) The only sea level rise we have seen over the last 100 years can EASILY be explained by the billions of tons of soil being eroded from land into the oceans by natural processes. Illustration -- if you fill a bathtub with water, then dump some sand in it, the water level will rise. (5) eh, I'm bored. Stop drinking the Kool-Aid. Think for yourself and truly analyze what's being said. Look at only the facts, and no the fiction.
The problem i have with this presentation is one, no views of the slides he is referencing and two he is misinformed or deliberately misleading the audience. It is a matter of public record that in the early 1920's ships Captains were reporting the sea ice almost gone entirely, the Seals suffering because of the warming there was very little sea ice for them to occupy and all usually closed sea roots open to shipping, but you won't find this repeated by any Global warmists it just blows their theories right out of the water, and lets face it how credible can their argument be if they continually lie and hide true Facts from us?

@@davidjaglin5507 You see i knew you were a fanatic, already closed to other facts or views, the fact that it was reported in the Media does not make it untrue these reports were from the Logs of Ships Captains of the day sailing those waters and it was widely believed that the sea ice was about to disappear all together, sound familiar? You see it pays to do some research before making up your mind, the constant discrepancies and down right lies that have in some cases been publicized by the Climate scientists is what first prompted me to look into the matter myself, you will be surprised at what you will discover, and taught me never to take for granted that so called experts could be trusted not to have an agenda. Try it and educate yourself before judging
flashpoint so you are science illiterate and can only understand overblown newspaper headlines, yet you brand me a fanatic? You have not presented any facts but made lazy and shallow assertions. I abhor your kind.
Many more polar bear triplets are being born than ever before. It is very possible that the polar bear population will reach 40,000 in the near future. We have never seen so many polar bears before.
I question the comment about the concern over the saltier surface ice and the interaction with the ozone. How does the saltier sea ice effect the reduction in ozone. It would seem I lack the knowledge to make the link. Please explain.
I also question the idea of trying to put crews on the ice after the longest day of the year. After the warmest months of the year this man claims to be unable to set-up on the ice during August and September. Trying to setup after the spring thaw and the hot summer sounds like a brilliant plan from the (smart) people calling themselves scientists. Why do I have more questions from this video than answers? And yes, I wonder like some others why many of the slides are seemingly not shown.

CO2 is causing...forcing...warming? When did they prove that?? (far more consistent un-adjusted data would seem to indicate that warming causes outgasing of CO2 from oceans / reversed cause-and-effect) And if CO2 forces temperatures to rise....and CO2 is increasing....how could we just have had a most brutally-frigid, extended winter....when CO2 is at record high concentrations??? (I wanna hear this 'spin'!! "Warming causes cooling!!!"???) Sure....we're warming. Has happened an uncountable number of times in the history of this globe. (and what do they find when glaciers melt? trees). The "Little Ice Age" (1300-1870) ended at the same time temperature records began (1880)....which is used as the baseline of ALL the "warmists'" line graphs....so we had BETTER be warming. (won't even mention how Greenland got its name around 1,000AD....) One has to wonder.....what was this guy doing in the 1970's when the Left was squealing about an about-to-happen ICE AGE??? (which reversed in about 25 years to "warming".....then switched to "climate change" when the warming quit cooperating) Skip all the "adjusted" data and nonsensical rantings from people on government grants. Just look at the source.....the Left. And the Left HAS to lie....nobody wants what they're really selling.
Warming, sorta... It's more like somewhat mild fluctuating with a vague warming trend that seems to disappear and reappear. It's a tiny warming amount, so small we need special climate scientists to measure it. And how do we know it's accurate? Because they said so! How do they compute the amount of warming? I wish I could get a straight answer. I have heard a few papers criticize certain statistical analysis about proposed warming. I have heard that certain historical temperature calculations have been "updated" with data to make the recent past COLDER to give an illusion of a temperature increase.
It is not a matter of global warming because there are areas of warmer and cooler climates based on the changes from human impact. The term climate change is a lot better because of people like you who dont really understand the science and thats not entirely your fault. Where I live I am also experiencing longer winters and this is because of climate becoming less regulated than what it originally was pre-industrial. The change doesn't appear everywhere as warming, some areas become cooler and some have a change in precipitation, as an average the world is about 0.8deg warmer, hence the global warming term. Without visiting places in the world dealing with the most change to their normal climates you should not speak on this topic, thousands of people are dying due to problems in the environments they have never had to deal with before. The climate is always changing and scientists have never said its not, the point is how fast its changing and the fact that most animals and plants cannot adapt at the same rate. Many species are dying already because of the changes to our Earth and you are extremely naive talking about a subject you clearly have no education on. Just because you dont understand something doesnt make it false and I strongly suggest for you to read some peer-reviewed articles or take a course to understand what is currently happening. Also from a logical point of view... it makes no sense for scientists to lie about something when they get nothing in return. Would you give up your life to research something that doesnt exist? Would hundreds of thousands of people do that? And go to school for 4-10 years? No they wouldnt. Also even the right and far-right has spoke about climate change and put in policies to reverse it, this goes far above politics and is not about money. There is wayyyy more money to be made on opposing climate change and continuing oil and gas, so no, climate change is not a commodity for 'sale'.
Since this talk, the arctic ice maximum collapsed this year and was recorded on feb 25. It was also the smallest ice sheet in recorded history. nsidc.org/arcticseaicenews/2015/04/a-double-dip/

So the great flood lasted thousands of years and this is where the story comes from.?!?!... But to get even more out there i wonder if people were forced to flee to Antartica but could one even live there even if most of it's ice melted? I suppose they could live on fish and seaweed to start with. I guess we will see once the ice melts. I'm not sure about the upper estimate of sea rising levels due to surface area, the meniscus effect, loss of hydrogen out of the atmosphere (from the sea water) and then there is the possibility of dredging also there is the amount of oil we pumped out and replaced with sea water. Not to mention the smaller volume melted water takes up over frozen water and could there possibly also be compression of water at great depths compressed further by the extra water above? I know water doesn't compress much but at such great depths the pressure is immense.
As of today 09/02/2018 6th lowest (do note also 2003 was a lethal ,heatwave in Europe and reasonably high arctic sea ice, however 2005 was a record low, 2010 was another lethal heatwave and 2011 and 2012 were record lows and so the pattern continues with small rebounds after record lows as the trend goes down. Note those heatwave years are also massive forest fires in the Arctic circle and sub arctic with massive smoke plumes and clouds generated shading the Arctic and protecting the ice
Some 70 years ago we were taught real science in school - topics such as the nitrogen and carbon cycles. Our forests and plants require atmospheric CO2 as "food", and cannot survive without it. Our physical bodies require a certain level of CO2 also. I too love CO2.

In most cases, the speakers are not up there to be featured in their own fabulous close-ups; they want to communicate something, and they've designed visual aids to help them communicate their important ideas. Please do them and your entire audience a favor by helping them out with that. Thanks so much! Respectfully.
Learning is a journey, not a destination.
@Jon Smith Many variations on that. Life is a journey, not a destination. Religion is a journey, not a destination.
Learning had better be a journey for me. I'm 71 years old and just finishing my master's degree. For some, the people who need the degree to get a raise or a certain promotion, it is a destination. But I think making it a destination does undermine the process learning.
People tell me sometimes, you're never too old. I tell them, on the other hand, maybe this is the right time. It could be.
And I soooooo agree with you!!!

This is TEDx
John Paterson Very poorly done. Typical amateur shoot.
@Trigger Troll NO they're not (spell check much?)!
@Trigger Troll Oh I see ... now why would you bother doing that?
exactly
great and wonderful information. If only we could see those slides !!! We CANNOT GO TO THE ARCTIC, WE MISSED THE TED TALK ALIVE. AND NOW WE MISSED THE SELF EXPLANATORY SLIDES . STILL THANK YOU FOR THIS GREAT INFORMATION
Sea Ice does not make sea level rise. Ice is frozen water so when ice melts the sea level does not rise. If you doubt that simple example try the experiment for yourself in your own kitchen. Fill a jug with water and ice and mark the water level on the side of the Jug, Let the jug sit until th eice melts and the water level will be at the same mark as before. So all the talk and talk is baseless it is really meant to mislead you to panic and somebody is making money so follow the money?
when the newest largest Norwegian ice breaker set out recently for the North Pole it ran into ice much thicker than expected , was damaged and had to return to Norway . I think the takeaway is that satellite estimates of ice thickness are not to be relied upon . also , there is significant yearly variation . ice cover is greatly affected by wind speed and direction . as of 2021 there is no statistical trend in arctic sea ice for the last 15 years .
Superb! Such a fluent and easily comprehensible presentation of a complex set of topics! My thanks to David Barber for choosing to do this as well as to TED and the University of Manitoba for the platform. However, as to the video itself, I join others in expressing that the slides were NOT clearly shown. Perhaps the screen can be split into two showing the presenter on one side and the slides on the other?
thanks TEDx,..this reminded me of radio.
Exactly.. video of the speaker but no slides or pictures what he's talking about could as easily be broadcasted on radio.
Observably trapped using more than what is necessary.
It was a lot warmer in the last Interglacial Period, and the Polar Bears made it through it fine. Who told you CO2 drives temperature? It never has in the past, (see Vostok ice core data). A warming during this interglacial period is not only possible, but likely as past interglacial periods have all been much warmer than this one, (Coolest interglacial in last 1/2 million years), we could warm by 4-6 degrees C. The last interglacial was 4 degrees C warmer than we are, and the oceans were 20' higher than now.
Real scientists have been studying the record of the planet's climate, using ice cores from Antarctica, among other places. You should learn what research is and how to do it. Search for Vostok ice core data graphs. Read the pear reviewed articles about their findings. You have only given us your title, "Dr. Climate Denier", and your name, Mr. "Duhhh". With all your studying of a picture of one area, over a relatively short time period of time, when do you predict the next Glaciation will begin? I'm guessing it will start sometime between now, and 10,000yrs from now.

Arctic ice coverage is at or near all time highs...
Yes it is, by 2019! So it took 4 years from 2015. Also Polar bear population is bigger than ever.
Also the Ozone layer is 20 years from being back to where it used to be, as the earth heals itself !
yes heard, i expected that to happen, they seem to think that planet earth is a hundred years old i know there is old cycles
Excellent talk presenting the facts. Always great (though spooky) to hear from someone who has worked in the Arctic region and speaks from first hand experience and observation.
Billions in funding for a 10 minute talk
He is wrong too !!
🛶🏹 Greenland was green with vineyards and forestry. ♻️🐂💨
I come from the future, 2019. We discovered that we didn't really know as much as we thought we did about arctic ice. Turns out it was just in a cycle and now we've got more than we used to. It turned out to be Much Ado About Nothing.
Powerful... i wish i can listen to update on this today (2021).
"The earth does not come with a manual"....hits me hard
I took me two minutes to realize this was from 2015. In the last four years the Arctic sea ice has increased considerably.
HAHA
The overall trend is not only declining extent but declining thickness as well.
Sorry DUde...It is 2019 and your predictions have fallen apart.
Not so!
Thanks for describing what has been going on since the beginning of time. Thanks again
U sir are a dingus
Dr. Barber has an appealing avuncular style. His presentation was in 2014, and describes an expedition in 2009. It is now 2019 so that is 10 years later. Has all the Arctic ice now gone? Are the Polar Bears gone? The Arctic is a relatively small conglomerate of floating ice chunks. Why no mention of the Antarctic which holds 90% of the world's fresh water as ice.
Too bad this guy is not familiar with history. If he was, he would know that around the year 1360, a group of Vikings from Denmark, led by Paul Knutson sailed into Hudson Bay and then up the river systems there, eventually reaching into what is now the state of Minnesota. They left a stone there that describes some of their exploits. The stone was discovered by a farmer and has since been named "The Kensington Rune Stone." It was thought to be a hoax for many years, but recent research has uncovered a document in the Danish archives that directs Paul Knutson to make the trip. Additionally, numerous swords and other Scandanavian artifacts have been unearthed by the plows of farmers throughout the region.
You might ask what this has to do with sea ice etc. The facts are that back then, things were so warm that Vikings had made permanent settlements in Greenland, where they grew crops and thrived because of the warmth. They eventually had to abandon their settlements as the weather grew colder. It is still too cold to grow the kinds of crops that archaeology has shown them to have been raising during their time there.
All of this shows us that alternations of cold and warm are the way of the planet, and that we out to simply adjust to the idea, rather be alarmed by it. For goodness sakes folks, we weven have fossil evidence that there have been tropical temperatures at the south pole in the distant past. Last but not least; CO2 is not poison, it's plant food. Don't let others do your thinking for you. Get out there and do your own research.
Craig Bowlby that’s just awesome
Fantastic text with beautiful info, great work im glad to have found it. Write more like this on youtube. much more! you are really talented, you should spread this exact text to as many places as possible, less work for you more joy for the lucky people who read it!

Don't fight nature, be part of it.
So much for the polar bear forecast.
There are people who study bears. Have you read their work?
@Pistol Pete You probably do a good job of scaring your kids all by yourself.
And yet another deflection by an alarmist. So, what personal insult are you gonna hurl at me, now?
This was a great presentation. I really wish the TEDx producers would show the slide when the speaker is referring to it, rather than focusing on the speaker :/
Thank you Dr.Barber for standing in this 21st Century AGORA & talking to us all!
It's 2019, 4 and 1/2 years since this was made. the ice on our north and south is growing. And, if it is too melt it would not be the first and it wont be the last. Polar bear population has increased since the recording of this.
site your sources please
Not true.
He is right about the south pole and polar bears. The last three years have seen a drop in temperature which is due to passing the grand solar maximum; this trend should continue until about 2044. It will be a few years before we see a definite reforming of the Northern ice sheets due to natural fluctuations.
Greetings, Very easy to search the massive Jakobshaun Glacier in Greenland, because of it`s scientific importance it is referred to as "The Canary in the Coal Mine" of Glaciers and was receding at the alarming rate of 1.8 miles per year and a reduction in depth of 130 feet per annum --- HAS STOPPED and is now INCREASING at the same rate as it was receding over the last 2 years.This video is 4 1/2 years old and there have been massive freezing events in the past 3 years in Northern Europe and Greenland. In 19 zones in the arctic the number of polar bears recorded has increased by over 8,000 in ten years, i am pleased to report. Kindest Regards.
@@nevillebuck9235 Yes, exactly, thanks for this!
are we at the end of an ice age? will the world look like it did before the ice age if all the ice melts?It seem man cannot control the weather so wouldn't it be better to accept change.
Nope we are at the end of the warming period and ice age "coming" (ok can be between few months to few centuries lool... but coming...
Big ice periods about 100000ans with a 15000-20000 warming period.
We are at the end of the actual one!
+variations of 400y, and this one is coming very soon! (Jupiter+saturn alignment starting 2019 )
Maybe the climate hoax on purpose to hide this reality and let the elites build their shelters and leave the rest of the world die on the surface! (with ice no food even if you manage to heat yourself)!
reference2me "t seem man cannot control the weather so wouldn't it be better to accept change." YES man can and has, and that is what climate change is, the manipulation and engineering of both weather and climate with technology.
Do ice breakers compound the shrinking of ice caps. If you break up ice it melts quicker. Maybe small consequence but can't help
Yeah and what about all that CO2 given off by their diesel engines
What a ridiculous comment.
Surprising result no. 8: the ice is growing.
In some places, however, it's volume is declining unfortunately.
Not declining, just changing locations. Antartic sea ice is at an all time high.
I like the notion at 11:20 that reduced ice at the north pole lets heat escape from the ocean.
Very enlightening ..... Thank you for your polar ice lecture.
I get paid to study the Arctic. Enough said except who's paying you? Now it's 2019 and the ice has been the thickest in 10 years.
haha, they probably thought they where going to get away with that fact in 2015 since back then most meida coverge was mocking all non mainstream(=political/commercial) views
Great informative, up-beat presentation. I love the part when he says that the Earth did not come with a "manual". So we have to trust our scientists and listen. Unfortunately there are a lot of people who troll on TH-cam for big oil. I just don't get it-how they can be so unconscionable?
What, you mean the Bible doesn't count as a manual? :)
The Bible is a plarized collection of fiction originally written by dehydrated desert dwellers recording their hullusanations.
Good for you if you want to believe people who got it wrong since 25 years my friend! There's science and there's scientist, you have to do the difference...
When the ocean is open enough, the resulting heating of the atmosphere over the Arctic ocean should become an area of rising air instead of falling air as it is classically. This should suck the climate zones northward and disrupt the major grain growing areas of the northern hemisphere. The polar jet stream should disappear and we might well have a two Hadley cell system in the northern hemisphere.
I have difficulty understanding what you are saying. With no ice there is no reflected summer heat, all you will have is refracted heat but a lot more of it will not be refracted, surely?
If not refracted it will absorb at depth. Do you have any idea how much that will be?
Also how have you managed to compute your thermohaline effect?
+William Hughes-Games Interesting thought thanks.
William Hughes-Games, thé effect of melting sea ice in the arctic is that we’re all fect.
I hope only that this all not leads to stalling of wind because of less difference between equator and poles. All our windmills would have problems then delivering at the moment when we need them most.
same explanation of polar vortex changes as attributed to global cooling in the 70's .you can assert anything if there is no way to falsify it
Wouldn't it be good to show the slides a bit more in this video....?
Good info, but almost all the graphics and video stuff is lost. I don't need to see the closeup of the speaker, but the entire presentation.
thats no coincidence
1. A Reminder of basic Physics.
Ice only contains salt if the ice water freezes too fast for the ice to reject the salt. So that rotten Ice.. would indicate a lower temp' at winter.
2. Water that distrupt the air above would lead the disruption.
So the vortex should have been over water. Not it the continental US. Not to mention Canada.
3. The old Ice is there anymore.
Same time- the old Ice is hazardous.
Ok.
Nothing like an audio version of a potentially visual presentation, but then most TED talks are like this , aren't they?
Oh David, BTW ,CO2 follows climate differential it does not create it.
johnnieo66 CO2 can follow climate diffs but it also can create climate diffs. In the case of CO2 follows climate diff, it boosts it if it is a positive diff.
@@davidjaglin5507 And I suppose this is science right?
Carlo Ammann Not sure what you mean.
Yes, with science we can predict and calculate the changes in the earth’s orbit and tilt. We can also calculate the forcing from greenhouse gases.
@@davidjaglin5507 Moisture in the atmosphere is the biggest cause of the greenhouse effect Not CO2, this is just another scare mongering story, more polar bears than ever, just a tax ploy
Donald Morton You should look into the carbon and water cycles. Increased CO2 increases atm temp which makes the atm hold more moisture....which increases atm temp....
Very interesting presentation. I'd love to see a follow-up to see whether the issues mentioned have continued, increased, or decreased. Is there still a lot of "rotten" sea ice, and is it more than previously? For polar vortex, there was certainly a lot of attention at one point, but it seems to have disappeared from weather discussion. Is that because the effect is now routine, or because it has migrated to different parts of the world, or because 2014 was just one freak occurrence? What other new and surprising results have come from ongoing research?
Very good talk. Thank you David Barber.
I'm really glad that you have the job you do, that you have colleagues, and that you are somehow paid for your services. Those of us who find science valuable and believable, love having this data put in front of us.
But rather than float about dysfunctionally they would have better spending research time finding how much faster the taiga is growing in the much more favourable conditions.
data and "evidence" can be manipulate so easily
The speaker needs to save this tape as his grand children will find it hilarious.
This is the only guy that didn't sound like an activist on climate change.
This was a graphic presentation without the graphics. Lots of great shots of the speaker referring to the graphics though. Too annoying to finish.
Im with you there! I havent been able to endure a single one of these "Tedx talks" to the end for the life of me!
You kids are still struggling with short attention spans. Keep working at it, you can only get better.
No ice equals major temperature increase.
Depends where you live... in Africa I could mean a temperature increase in Europe it could mean a temperature decrease.
I’d like to see a similar dissertation for Antarctica. I’m reading that though the sea ice there may be thinning the terrestrial ice is growing. My question is what effect this imbalance in weight distribution will have on the planet as a whole. He doesn’t mention the magnetic pole migration which appears to be speeding up and racing toward Siberia. A pole shift seems to be in progress. The earth’s EMF plays a big part in changing weather patterns as well. A grand solar minimum has also begun reducing the amount of energy reaching the earth leading to cooler temperatures as well as causing an increase in both volcanic and tectonic activity. CO2 concentrations is just one part of a very complex system
Immanuel Velikovsky had some interesting and scary things to say about crustal shifts which could occur as a result of a weight imbalance. Additionally, this presentation makes no mention of the now rapid migration of the magnetic North Pole. Changes are afoot
Would have been REALLY nice if we could have seen the slides he is referring to!!!
Our planet is a constantly changing environment. Thinking that a single place on the planet is going to have the same environment such as temperature or amount of ice, year after year is an erroneous supposition in and of itself. Even the magnetic poles and spin of the earth are changing. You can try to measure the conditions but the results don't really give us as much a conclusive value as some are suggesting. Think of the human body or financial investment. Past performances are not necessarily indicative of future results. I have no problem with people making predictions based on past performances, but we should never take them to the bank and God forbid, let politicians alter our economic future based on these type predictions.
it's obvious to just about everybody, climate change is real, but human kind will adapt, and survive .
Crop yields are making significant gains, as a result of additional atmospheric CO2.
@@randallsemrau7845 Whatever yield may be gained by an increased CO2 level will be more then wiped out by the increased frequency in heat waves, drought and flood. But of course you are more into misinformation then providing the whole story aren't you??
What a well-crafted efficiently delivered overview! Bravo!!!!
Myopic nonsense. Hello ? There is a much better indicator. It is called the Antarctic. Ice levels on land and sea have been slowly increasing. Where is his talk about that ? The north ice is on water and means that it overreacts like a hyper 3 year old in regards to small yearly temp increases and decreases. Look to the south for the truth.
But not a word about the record large amount of growth (winter maximum) or the growing ice caps in Antarctica...
There are no growing icecaps in the antarctic. The sea ice there is greater in the winter, but it is because of all the freshwater melting off of the continent that freezes faster than saltwater. The surface of the sea around Antarctica is diluting from the runoff of all the melting ice on land.
Due to the size of Antarctica and the circumpolar current both ocean and atmospheric there is an increase in snow well inland (was always in the models , in fact due to it's peculiarities Antarctica melt was not expected until next century), but happening much quicker due to the warmer oceans eating the ice away from underneath and allowing the great ice sheets to flow down to the ocean. It has also been far warmer in West Antarctica and the loss of land ice there is resulting in a rebound of the crust, this matters because it is a volcanic region (lots of volcano's on East and West Antarctica) and that rebound is altering the viscosity of the crust and mantle as pressure is being reduced on volcanic vents and magma channels meaning increasing volcanic activity as the magma plumes head crustward, this will just melt more ice.
Tipping points are being approached all over the place
Frank Speaking yeah you’re right there are a lot of volcanoes, but only on the western side really. It doesn’t change the facts that the glaciers and ice caps in the southern region of this planet are indefinitely growing. New Zealand, the Andes, and Antarctica, all follow the same trend.
Wrong, the worlds tallest ACTIVE volcano is in East Antarctica - there are plenty of volcano's and active areas under East Antarctica, look it up.
The thing is they tend to be well inland and as a result are covered by mile high ice sheets and actually in many cases provide under ice oasis with huge liquid lakes with life and a slow leakage of water along the bedrock
It is the trend over time as the ocean and atmosphere cycles do their magic, South America is actually facing future water issues as so many are dependant on meltwater from rapidly shrinking glaciers, watch and learn, one swallow does not spring make
What reduction of arctic sea ice ????? The arctic sea ice shelve has been ~ stable - summer and winter extent - since 2006, despite of all of the greeny propaganda to the contrary !
couldnt have said it better.
How do you know - did you go there?
@@NapoleonGelignite ever heard of satellites son?
@@j_forfreedom45 - you mean the instruments that clearly show the thinning of the ice and the snow line retreat?
I'm glad you accept satellite measurements, many deniers pretend they are not 'real' sources of data.
What? Well thank you for glancing at a climate change video but please ask your questions to the algorithm
This TED talk occurred 7 years ago. Conditions in the world and the arctic are not the same. Watch another TH-cam lecture by another scientist Dr. Patrick Moore called Climate Realism where he talks about what was more current in the Arctic a year ago.
Latest modeling shows an ice free arctic projected for fall of 2022. This constitutes the first in a series of tipping points daisy-chained like dominoes. When the last domino falls... Well. The only complex life forms will be extremeophiles. There is no getting out of the way. There is no "turning this around". If the whole world dedicated it's efforts to conservation and amelioration perhaps we could slow it down a little, maybe give us another 100 years. That's not going to happen.
Do you suppose the Creator will forgive us the destruction of Creation? Oh right, some of us are pre-forgiven, I forgot.
/read sarcasm/ You can't build a society based on greed and ego and expect good results.
See you on the other side. Be brave.
They use satellites to monitor and measure the ice. But he never explained how they measured it 1000 years ago.
Where's the data, show me so l can make up my own mind.
Sounds to me like you're fishing for funding.
O.k. show me the data from the past 1000 years...........
Still waiting.........

Oh I see, you have no data.
Good by.
No pay if there's ice, I got it now Sumpter, Tullonius
Ever wonder why Dr Barber and his ilk only focus on the Arctic while never mentioning the other polar region aka the Antarctic?? It's because ice has been increasing in that region which not so conveniently contradicts the narrative.
Mr. Barber R.I.P.
The valid information in this TEDx is directly proportional to the time spent looking at the screen.
It would be great if he HONESTLY explained all the assumptions they use as foundations to their claims.
can we see the screen please. we do not need to see the man but if he is talking about the screen we need to see it.

A Scam is what it is, the weather and climate is controlled.
There are now more Polar bears than in living memory.
He mentioned the Mediӕval Warm Period. That's a "tenner" in the Gulags !!
So where do you stand now that the ice has returned in great amounts? You haven't deleted all your videos.
The effect of CO2 in the atmosphere is known science. Some things have been worked out not only in theory but confirmed by experiments. Oh and btw google what has happened to plankton.
Dan Kelly "Known science?" All "science" is is the practice of observation, collection, hypothesis, and testing of something. Saying it is a "known science" suggests you have no idea what you are talking about. Now, assuming I think I know what you meant to say, all (I repeat, ALL) predictions we have on what happens if we increase CO2 is purely theoretical, built on MANMADE MODELS that have so far been wrong. Every single prediction has been wrong!
Let's take a look at Al Gore's famous hockey stick. During the Industrial Revolution, global temps WENT DOWN, not up. During the Great Deoression, global temps went up, not down. Hmm! During the WW2 era, global temps went down. Oops!
Ahh, come on. Your retort is an attempt at insult? So much for intellectual conversation or debate. But, I see it all the time. It's okay. When people don't understand enough to debate, they get into name-calling. I see where you are intellectually now. Thank you.
@Rick Torbet
The effects of CO2 is well known and replicable in a laboratory, *IT IS NOT PURELY THEORETHICAL*
The reason models are used, it is not exactly sure how much the earth climate sensitivity is but that it is undoubtedly resulting in increased global temperatures, that is observed facts.
It would be a mystery if increased CO2 levels did not result in raised temperatures.
The models are pretty accurate, don't know what you have looked at.
CO2 is not the only factor that affects the temperature it acts like an amplifier, in the end it is about how much solar irradiance that reach earth and that varies but CO2 is undoubtedly increasing the temperature from what it would have been without it.
Good example look at the moon....
The fact that not every year is the warmest ever is of course a good thing, meaning of course some years temperatures goes down but the trend line is clear, steady rising temperatures.
Al Gore is not a climate scientist he is a polititian, not a great source for facts, he did get some things wrong but reached he'´s objective.
What the alternative to "Man made models" is I do not know, stone tablets from God??
Umm NO. There is no evidence that increased temperatures is "undoubtedly resulting" from increased CO2. We really don't have any evidence in increased global temperatures at all. We see slight increases in some parts of the earth, and slight decreases in other parts of the earth. That suggests BALANCE, no imbalance. It doesn't help that our "global warming" data points have been altered. Some have been removed from the data in colder regions to help skew the data to make it look like the whole earth is warming.
Again, you are drinking the Kool-Aid!! "but CO2 is UNDOUBTEDLY increasing the temperature..." Again, there is no proof that CO2 is the cause of temperature increases, if we even have increases.
"The trend line is clear, steady rising temperatures." That would make sense, since every single "old earth" scientist believes we are coming out of an ice age.
One thing people fail to recognize is if CO2 in the atmosphere prevents the sun's energy from escaping (warming) it should also prevent the sun's energy from penetrating (cooling).
Here are the REAL FACTS.
(1) The earth may or may not be warming, as data points have been removed to purposely skew the observations.
(2) Plants are starving for CO2, and the limiting factor in photosynthesis and plant growth is not enough CO2. Plants remove CO2 from the atmosphere. If Democrats really wanted to stop increases in CO2, why do they make it impossible for Californians to grow grass? ZERO-SCAPING IS BAD !!!
(3) Concrete production creates far more CO2 than an entire army of tanks. Why does no one ask that we go back to dirt roads?
(4) The only sea level rise we have seen over the last 100 years can EASILY be explained by the billions of tons of soil being eroded from land into the oceans by natural processes. Illustration -- if you fill a bathtub with water, then dump some sand in it, the water level will rise.
(5) eh, I'm bored. Stop drinking the Kool-Aid. Think for yourself and truly analyze what's being said. Look at only the facts, and no the fiction.
The problem i have with this presentation is one, no views of the slides he is referencing and two he is misinformed or deliberately misleading the audience. It is a matter of public record that in the early 1920's ships Captains were reporting the sea ice almost gone entirely, the Seals suffering because of the warming there was very little sea ice for them to occupy and all usually closed sea roots open to shipping, but you won't find this repeated by any Global warmists it just blows their theories right out of the water, and lets face it how credible can their argument be if they continually lie and hide true Facts from us?

@@davidjaglin5507 You see i knew you were a fanatic, already closed to other facts or views, the fact that it was reported in the Media does not make it untrue these reports were from the Logs of Ships Captains of the day sailing those waters and it was widely believed that the sea ice was about to disappear all together, sound familiar? You see it pays to do some research before making up your mind, the constant discrepancies and down right lies that have in some cases been publicized by the Climate scientists is what first prompted me to look into the matter myself, you will be surprised at what you will discover, and taught me never to take for granted that so called experts could be trusted not to have an agenda. Try it and educate yourself before judging
flashpoint so you are science illiterate and can only understand overblown newspaper headlines, yet you brand me a fanatic? You have not presented any facts but made lazy and shallow assertions.

@@Policesamuri77717 Have you been counting them?
I question the comment about the concern over the saltier surface ice and the interaction with the ozone. How does the saltier sea ice effect the reduction in ozone. It would seem I lack the knowledge to make the link. Please explain.
And can’t see almost any of the slides. What is the logic in this? Creditably is badly effected by such basic omissions such as this
I also question the idea of trying to put crews on the ice after the longest day of the year. After the warmest months of the year this man claims to be unable to set-up on the ice during August and September. Trying to setup after the spring thaw and the hot summer sounds like a brilliant plan from the (smart) people calling themselves scientists. Why do I have more questions from this video than answers? And yes, I wonder like some others why many of the slides are seemingly not shown.

omg all marine biologists mention cocktail parties
CO2 is causing...forcing...warming?
When did they prove that?? (far more consistent un-adjusted data would seem to indicate that warming causes outgasing of CO2 from oceans / reversed cause-and-effect)
And if CO2 forces temperatures to rise....and CO2 is increasing....how could we just have had a most brutally-frigid, extended winter....when CO2 is at record high concentrations??? (I wanna hear this 'spin'!! "Warming causes cooling!!!"???)
Sure....we're warming. Has happened an uncountable number of times in the history of this globe. (and what do they find when glaciers melt? trees). The "Little Ice Age" (1300-1870) ended at the same time temperature records began (1880)....which is used as the baseline of ALL the "warmists'" line graphs....so we had BETTER be warming.
(won't even mention how Greenland got its name around 1,000AD....)
One has to wonder.....what was this guy doing in the 1970's when the Left was squealing about an about-to-happen ICE AGE???
(which reversed in about 25 years to "warming".....then switched to "climate change" when the warming quit cooperating)
Skip all the "adjusted" data and nonsensical rantings from people on government grants. Just look at the source.....the Left.
And the Left HAS to lie....nobody wants what they're really selling.
Warming, sorta... It's more like somewhat mild fluctuating with a vague warming trend that seems to disappear and reappear. It's a tiny warming amount, so small we need special climate scientists to measure it. And how do we know it's accurate? Because they said so! How do they compute the amount of warming? I wish I could get a straight answer. I have heard a few papers criticize certain statistical analysis about proposed warming. I have heard that certain historical temperature calculations have been "updated" with data to make the recent past COLDER to give an illusion of a temperature increase.
It is not a matter of global warming because there are areas of warmer and cooler climates based on the changes from human impact. The term climate change is a lot better because of people like you who dont really understand the science and thats not entirely your fault. Where I live I am also experiencing longer winters and this is because of climate becoming less regulated than what it originally was pre-industrial. The change doesn't appear everywhere as warming, some areas become cooler and some have a change in precipitation, as an average the world is about 0.8deg warmer, hence the global warming term. Without visiting places in the world dealing with the most change to their normal climates you should not speak on this topic, thousands of people are dying due to problems in the environments they have never had to deal with before. The climate is always changing and scientists have never said its not, the point is how fast its changing and the fact that most animals and plants cannot adapt at the same rate. Many species are dying already because of the changes to our Earth and you are extremely naive talking about a subject you clearly have no education on. Just because you dont understand something doesnt make it false and I strongly suggest for you to read some peer-reviewed articles or take a course to understand what is currently happening.
Also from a logical point of view... it makes no sense for scientists to lie about something when they get nothing in return. Would you give up your life to research something that doesnt exist? Would hundreds of thousands of people do that? And go to school for 4-10 years? No they wouldnt. Also even the right and far-right has spoke about climate change and put in policies to reverse it, this goes far above politics and is not about money. There is wayyyy more money to be made on opposing climate change and continuing oil and gas, so no, climate change is not a commodity for 'sale'.
I cannnot watch it, the slides do not show ???
Since this talk, the arctic ice maximum collapsed this year and was recorded on feb 25. It was also the smallest ice sheet in recorded history.
nsidc.org/arcticseaicenews/2015/04/a-double-dip/
Just like Al Gore, you were TOTALLY WRONG. Since that comment, ice levels hit a record high. HAHAHA.
June 2018, Arctic ice has increased back to the 2005 level.
It would help if the camera focused on the board and not the speaker????
Global Warming • they want your money
The Lord of Global Warming ... Alvin Gore told us the ice would be gone by 2013. In fact, in 2013 the ice was twice as large as it was when Alvin made his predictions. OH, and Polar Bear numbers are at a record high. This guy is a clown!
Typical of educational establishment is that you never get a good presentation.
What happened in the end I went to sleep are all the polar bears growing flippers.
haha i like your kind of humor mate
Will:
8,000 polar bears in 1950.....30,000 now. (time to start thinning the herd---don't tell GreenPeace!!)
@@deanlarson2375 id love to hunt some white bear...my grandfather hunted a grizzly in Yellowstone park, still have a pillow made of the fur, the rest got eaten by mice.
Gonna be amazing what happens when they blow it and cover vast areas of the arctic with oil spills.
and yet nobody says a peep about Norways drilling in the arctic because they are so "green ".
very good presntation, thanks!
So the great flood lasted thousands of years and this is where the story comes from.?!?!... But to get even more out there i wonder if people were forced to flee to Antartica but could one even live there even if most of it's ice melted? I suppose they could live on fish and seaweed to start with. I guess we will see once the ice melts. I'm not sure about the upper estimate of sea rising levels due to surface area, the meniscus effect, loss of hydrogen out of the atmosphere (from the sea water) and then there is the possibility of dredging also there is the amount of oil we pumped out and replaced with sea water. Not to mention the smaller volume melted water takes up over frozen water and could there possibly also be compression of water at great depths compressed further by the extra water above? I know water doesn't compress much but at such great depths the pressure is immense.
It's now June 2018, and the Arctic ice has INCREASED to the 2005 level (13 years ago).
IPCC climate model fail !
Simon Ruszczak
And you cant read data.
As of today 09/02/2018 6th lowest (do note also 2003 was a lethal ,heatwave in Europe and reasonably high arctic sea ice, however 2005 was a record low, 2010 was another lethal heatwave and 2011 and 2012 were record lows and so the pattern continues with small rebounds after record lows as the trend goes down. Note those heatwave years are also massive forest fires in the Arctic circle and sub arctic with massive smoke plumes and clouds generated shading the Arctic and protecting the ice
not the thickness,there is hardly any multiyear-ice left, dont be so thick in your mind...grow and wisen up. Kevin Anderson might help.
I believe seagoing tug boats could redirect the icebergs away from stationary vessels, however slowly?
Dennis Salisbury even better could bring them to tropics and give us respite from heat
So as of 2018, arctic sea ice has gone thicker, according to other YT videos, so just cancel what he has just said.
you mean has n o t got thicker, which loads of vids clearly show. liar!
September 2020. Lowest amount of old ice on record. Second lowest area. Latest start of refreeze, it's almost November.
@@gbeachy2010 march 2021 , a lot of winter freezing has put sea ice level above recent years and near 30 year avg . just got a late start I guess .
I love CO2!
Some 70 years ago we were taught real science in school - topics such as the nitrogen and carbon cycles. Our forests and plants require atmospheric CO2 as "food", and cannot survive without it. Our physical bodies require a certain level of CO2 also. I too love CO2.
I eat CO2 in the form of organic produce everyday. I’m a carbon based life-form. Without CO2, I wouldn’t exist.
Sustainably develop the oil and gas under the Arctic? Is he kidding? Up until then it was a pretty decent presentation.
You clearly think the UN climate change and Sustainable Development aka Agenda2030 is about about preserving the enviorment
it's not, it about controlling all resources and depopulation.
The weather and climate are engineered and have been for 7 decades.
pas9ify what’s wrong with exploiting our resources for the betterment of mankind?
@@RosyOutlook2 read my comment above.......I think I have the right answer to this "climate problem"!!
@@pulmo1 HAHAHA.......youre funny
I bet you believe boxcutters and pressure cooker bombs too!!
Thank you for not ringing the panic bell.
That’s no way to raise research funding.
so again its changing over1400 years and they have no clue
thank you David. I liked your presentation and you!
yea too bad the pictures didnt accompany the description rather frustrating .Interesting talk though
Agreed, missed the photographic half of the presentation.
Tell it to the vikings
He would be saying the same thing over and over and over and over if he never died. Every couple of thousands of years this very thing happens. But you all just think time started in 1929
I got bored , did he mention volcano activity under the ice?Probably not because he wouldn't get funded .
He is talking about ARCTIC sea ice cover. No submarine volcanic activity beneath the Arctic. Some in West Antarctica but of very limited importance.
@@pingobongo James Edward Karris ( geologist) published in January 2016 that there has been volcanic activity under the artic region also. And yes there are 91 volcanoes under the Antarctic region.
@@brianwalrod2253 Well, this talk was from 2014, was it not?
@@Oskariix You're right , he didn't have this knowledge available . But the volcanoes were already there . Plus he forgot to mention the Vikings sailed thru this sea ice area in the past , because there was no ice.
