The Vikings farmed on Greenland. That was when there was a long warm period. Fast forward to my dad being stationed there in 1953-54. You could not grow crops there. There are and always have been weather cycles of warming and cooling. It is all controlled by sun spots and flares.
That is actually not true Vikings miss named greeland and Iceland on purpose to confuse and thereby keep the secret Iceland is green Greenland is icey Considering Denmark ,Norway , Sweden and Iceland are at lower latitudes than greenland why would they try to grow anything up there The cycles you are talking about usually are between 30.000 and 100.000years (it might seem a lot but in geological periods it’s nothing) The Viking were more like 1000 years ago The 1 Km (1000 m) ice sheet in greeland looses 2 to 4 cm a year that’s around an inch and a half And that’s with the ozone whole,the post revolution pollution levels etc…. I don’t think Vikings ever touched the earth beneath the ice in greeland

Ive heard that the Greenland Ice sheet is getting thinner for years now, and yet a group of WW2 aircraft that landed there in the 1940's is now covered with over 300 feet of ice and snow. Maybe it's all getting thinner except the area the planes actually landed, I wouldn't discount any excuse they might use to dismiss an obvious observation. One of the aircraft, a P-38 lightning, was eventually recovered and restored it's called Glacier Girl, you can look it up.
20cm- a meter...... maybe more! Golly---- perhaps its 'maybe less' Computer generated "pictures" that are hokey!! Why no REAL pics? What about those planes? This is an adventure in guestimation designed to instill fear for the purpose of controlling the masses!
Monster Inc. correct you are old boy!!! About Glacier Girl. There is videos of her here on Censortube. Aka TH-cam. Her flying!!! Oh. She was so well preserved that it took very little reconditioning to get her to fly!!! In fact it took longer to re-paint it then it did to rewire her in places it needed
Are you kidding yes? If you put something more dense than snow or even ice on such surface it will drown slowly during that time. That is why all ice cap polar bases are built like it on swamps. On the pillars! Go back to learn things properly. Very poor comment. Interesting subject but lack of understanding water/snow/ice physics.
FYI: After some calculations, in 10 years about 0,09% of the icesheet in Greenland has melted. Don't be mislead by graphs, the red doesn't mean gone. Greenland icesheet: 2850 tera-tons | Amount melted: 2.5 tera-tons | Amount melted: less than a thousandth Also measurements started in 2002, what about last 10,000 years?
This is all bullshit, easy to tell as soon as you see the NASA logo. No one has been to the moon, anything NASA is fake! Watch Owen Benjamin, we didn't go to the moon.
In 1985, Al Gore said that by the year 2000, the coasts of the USA would be under water. It has not happened. I lived on Florida's Gulf coast in those days.

And the Gulf has not risen by one tenth of one centimeter since then.
@rogerpattube I have her as my professor and she knows this topic in depth. She is actively researching that issue here at UB. There is proof that if that glacier is experiencing cracks and freezing and melting points are causing it to leak into the ocean than so are other glaciers as well.
An interesting presentation, it brought to mind cities that in ancient times were port cities and now they are hundreds of miles from any salt waters. We seem to have been here before.
So what was the ocean level in 1100AD, when the Vikings were still farming on Greenland? Can't scientists easily determine that, to give us an idea of what the sea level would be if most glacial ice was gone from Greenland?
What I find interesting is that within the cooler water, the intermolecular attractions line up complex molecules ( such as polar proteins like RNA, DNA) and encourage the proper alignments for chemical reactions much, much better than the random high energy motion of molecules in a heated environment. Perhaps, the periods of glaciation have had greater impacts on the diversification of organic molecules and, perhaps, the evolution of life on this planet than the periods of warming? No idea - but this was my first thought on learning of the effects of glacial water cooling on molecular motion in published research. (Norwegian?) Apparently Greenland ice mass (as well as Antarctic ice mass) has increased in mass since this talk was made, and sea levels have dropped according in both Greenland and New York, as they have cyclically in the past. Don't believe me, check the data. We have had 'emotional reactions' to periods of warming and periods of cooling in the past. Don't believe me, check the literature. Peace.

Carlos Nells there’s a documented Viking colony that lived in Greenland for nearly 100 years during a time of natural warming around 1200AD. The colony was abandoned because it got cold again and farming became unsustainable so the colony went back to Iceland. You can still see the remnants of the church and main hall foundations. There were also Inuit tribes living along the coast and they were very hostile toward the vikings.
We allready did. You really don't believe the Egyptians were able to cut stone with precision using copper tools do you? With today's technology we still can't reproduce stuff we've found.
In the next 80 years...the sea level was already expected to rise 20 cm...its been doing approximately that for 10s of thousands of years...but wave your hand as if your expecting a few meters..the IPCC prediction was 48cm mean by 2100..
This video is a lie. NASA satellites say Greenland has a net gain of 30-150 gigatons and Antarctica has a net gain of 50-200 gigatons per year. Greenland ice sheets would melt completely if it warmed 3degrees farenheit. Do the math, thats 37.4 degrees farenheit. of course the ice sheets would melt completely. Even the provenly fraudulent report by the ipcc (the report they publicly apologized for) says that at the most the world will rise 3-6 degrees farenheit in the next 100 years. Far from the 37.4 percent required to melt all the ice on the poles. Not only that, but u.s. emissions are going down, despite leaving the Paris Accord, while Russia and China have no obligation to BEGIN placing policies to curb their emissions. While we payed for 60% of the Paris Accord. Why is it they want u to quit burning gasoline, but they're letting China and Russia emit as much co2 as they want.

I spent three summers up on the Greenland Ice Sheet during grad school from '94-'96. A fantastic place to visit. Nothing but white snow for hundreds of miles in any direction.
I'll start to believe some of these more extreme sea level rise estimates when they stop building on the coasts and start moving existing structures further inland.
I think you're being a little optimistic on the strategic foresight front there, buddy....somehow can't see the wealthy investing in inland villas with infinity pools in the expectation of a nice sea view in 30 years time, eh.
I want to se a simple Calculation. The worst case. You dont need money for years. How much water volume is over Greenland? How much mm is it, if you put it into the world, into the oceans. Subtract the water, which goes into the air, when heating up. Heating up is the reason for melting. So take this into acount.
@@newman5901 Your missing my point mate - climate change is global not local, Greenland doesn't exist in isolation does it? Incorporate the world's ice caps and surely you don't need precise calculation to know we'd have a significant issue. And what happens to water when it goes into air? Evaporation turns liquid into gaseous form which, inevitably, turns back into liquid form. It's a finite process. The more liquid (and gas) from solid ice, the more floods.
Dales Customs...... Think About It. There is WATER under ICE. Ice is LIGHTER THAN WATER. Put ice in a glass of water and SEE the ICE FLOAT to the TOP. Check out the POND covered with ICE. Make sure it is THICK enough before you skate on it.

Just because you just found out about aquifers in ice sheets, doesn't mean it hasn't been happening for millions of years. Although the "Two Year study" 2003-2005 by NASA, which took detailed elevations of the exterior of the ice sheet, seems to indicate a loss in ice mass, this is based on the outer size of the sheet, not its density. A new study by a Norwegian-led team used the ERS data to measure elevation changes in the Greenland Ice Sheet from 1992 to 2003 (11yrs), finding recent growth in the interior sections estimated at around six centimetres per year during the study period. Once again NASA takes a tiny bit of data, that fits their model best, and predicts all sorts of nonsense. ESA has had at least one working radar altimeter in polar orbit since July 1991, when ERS-1 was launched. ESA's first Earth Observation spacecraft was joined by ERS-2 in April 1995, then the ten-instrument Envisat satellite in March 2002. The result is a scientifically valuable long-term dataset covering Earth's oceans and land as well as ice fields - which can be used to reduce uncertainty about whether land ice sheets are growing or shrinking as concern grows about the effects of global warming. www.esa.int/Our_Activities/Observing_the_Earth/ERS_altimeter_survey_shows_growth_of_Greenland_Ice_Sheet_interior
Could be but not definitive. Dead viking bones or any tools can't be found in Greenland, only the footsteps of houses can be found, they are either eaten(cannibalism among last vikings), or they been killed by inuit, that is a big question.
@@someguyfromarcticfreezer6854 It's just as reductionist to use the term Inuit to describe all polar aboriginals as it is Eskimo or Esquimau. There are multiple tribes.
turns out you have to nuke the cubes in a glass of water... I suspect that the energy is concentrated in the water not the ice cubes, which do eventually melt once the water has heated.
"The aquifer water drives the crevasse all the way to the base of the ice sheet, a thousand meters below". "The Greenland ice sheet is huge, the size of Mexico. And it's ice from top to bottom is two miles thick". So...is the ice sheet thickness a thousand meters, or two miles??? BIG difference! (Unless the snow {aquifer} is over seven thousand feet.)
The name Greenland was given by the norwegian viking Erik "the Red" Thorvaldsen around 985 a.c. as he tried to allure settlers to move to the island from Iceland and Norway. The climate in the southern regions at that time was mild ("green"), hence the name.
Ms. Poinar is wrong about the rise of sea level. It is rising at the rate of somewhere between 0.6 to a maximum of 1.2 mm per year. This is according to the U. S. Coast and Geodetic survey, which as been taking these measurements for the last 140 years. The U.S.C.D Survey is more accurate than satellite surveys and is the authority on sea level rise. I dare say this is one of the first sources Ms. Poinar should have checked. We are 1/5th of the way through Al Gore's 1998 predictions and the sea level hasn't risen 1 inch!
Very cool comfortable spring in Texas this year (2021), it's often 95 by now but we linger in the 80's with cooler evenings and mornings. I figure it's impossible to melt that much ice into ocean without causing temps to drop as well. I'm also figuring on a murderously hot summer when it finally gets here.
No it will not drop the temperatures it will raise them. He'll stop the North Atlantic conveyor current. What happens is it will stop removing the heat from the equator and transporting it up the planet. It will get way colder in the north and stay hotter at the equator. But that much water is a factor. But removing that conveyor belt of warm water will make so much eat at the equator that it won't make much difference on the temperature would be my guess. I mean of the water anyway up north. The volume of water itself will not lower the temperature it will actually prevent the planet from cooling itself like it does now.
Ice two miles thick covers all of Greenland. And it's lost so much ice, enough to cover all of Australia 2 feet deep! Well if Australia is 3.5x the size of Greenland, Greenland's ice must have diminished by over 7 feet! Doesn't seem like that is such a big impact on ice that was 10,000 feet thick.
A much simpler and more accurate method of determiming the amount of glacial loss is the hundreds of millions of years of geological record. The ice caps have grown to cover europe and even canada in 2 miles of ice thrn receded to zero ice cap over and over again throughout the history of earth with water.
When the Vikings sailed to a large island which was lush and green they named it greenland and they lived there happily for three hundred years. Then it started to get colder and eventually it was completely frozen over so most of them left and headed back to Scandinavia! So don't panic about it melting now. Maybe we have sped up the process but it was due to happen anyway!

You act like we did no science for hundreds of thousands of years, then out of the blue we suddenly knew how to get to space. It took thousands of years of scientific learning to reach the point of spaceflight. The reason why we did "nothing" for thousands of years before that is because there were barely any organised groups of people. We mostly lived in small hunter gather communities that only needed to survive. Then as circumstances changed we migrated, invented farming and developed civilizations around 10,000 years ago. What is so hard to understand about that? Just because you don't understand what exponential growth is, doesn't mean there is some unknown history of humanity hidden under Greenland.

The Danish meteorological institute has data showing that the mass balance is positive not negative. That is to say that the mass of ice is increasing by approximately 350GT per year. This is the opposite of the data presented here - which is curious. How can two sets of data, apparently referring to the same phenomenon, yield such conflicting results?
What a lot of people don't realize is that when the Norsemen (Vikings) reached Iceland it was winter and the land seemed relatively icy compared to the lands they knew: i.e. Denmark, Britain, and even Norway. When they reached Greenland it was mostly green. The icecap was relatively small compared to what it is now.
@@lloydzilinski4401 Not fully true, Ice cap in Greenland was almost the same, but Vikings hit cost line during short summer and saw green hills. They discover Iceland in it's most icy place (south east) and name it after it. However they may re-discover Iceland after suggestion that island was known to Celts from Ireland and Scotland before (6-8 century A.D.).

Look up tony heller on TH-cam and get the real data!! It’s very different because he uses thermometer readings and real records, not computer models. It’s eye opening and much more interesting than these “ experts”
Right, he uses a thermometer to measure how much ice Greenland is using annually (and seasonally) and how the water flows through the ice sheet to the bedrock. That is pretty darn amazing. And yes, Tony Heller is an expert why?. He watched Grace Anatomy, and now he is a neurosurgeon, or the climatic equivalent thereof?. What is it with you people and your disdain for experts.

2:03 This graph is fake. Greenland is not losing ice. Every year, more snow falls than melts. Some years are more than others. In 2017, when this video was published, 540 gigatons of net ice remained on Greenland. In 2018, 500 gigatons of net ice remained on Greenland. That's 1.04 Teratons of net ice in 2 years. My data comes from the Danish Meteorological Institute. TH-cam will not allow the link for obvious reasons.

@You may be right, I may be crazy. Who's the real moron here? You attack people for imagining personal attacks, while personally attacking them. And fail to notice.
Are you serious? If you are it's just ignorance to evidence of climate change. You trust a qualified airline pilot or doctor (in an emergency) but don't trust authority if your life doesn't depend on it and it gets in the way of your opinion.
The rate of melting or flowing is more than likely directly proportional to the amount of ozone in the atmosphere, the ozone is like a hole in the atmosphere, allowing more uv rays to punch through our atmosphere, hence, heating up the oceans. Does a 1 degree (warmer) change make a difference in our climate??
MELT THE ICE!!! I want to see what Greenland is SUPPOSED to look like! Maybe it will look like Iceland, then I could go there on vacation all the time.
Yes, and this will also create more land to build new buildings, businesses, houses, etc....People can resettle in the northern part of the country some day!!
@De mon It was misnamed. Basically, Greenland and Iceland should have swapped names. Or, Erik the Red was at best optimistic when naming it to try to convince others to come farm it with him. Every group/culture that we know of that ever lived there lived right on the coast, Vikings included. They had no choice but to live on the coast because the place is almost completely covered by that huge ice cap, which is white
The sea level change has another implication that you don't hear discussed in the video, that enormous weight when redistributed results in a proportional shift in the underlying magma and this may have seismic implications on a global scale.
What about adding all that fresh water into the ocean? I remember something about the oceanic conveyor it could cause cooling in Europe? I will have to read up on this. Very well done!!!
George Sabol. Some scientists have said that the melting of the polar ice caps could change the direction or stop the golf stream which brings warmth from the Carribean area to Europe. This would result in Europe becoming colder. And I hope that doesn't happen or my home country Finland could become as cold as Siberia.
Paul Marchant. So you are just going to leave it there without giving any explenation as to why you think that? And yes, the Earth's crust isn't just floating on a sea of molten rock because the borderline between the crust and magma layers isn't tgat easy to define. The rock just gets hotter and therefor softer the deeper you go. So saying that the crust is floating on a sea of magma gives a bit of a false image of the reality.
in 1945, a couple of p-38 airplanes were forced down due to weather on the surface of greenland. the planes remain ther today with the exception of one retreived well over 100 feet down. now, the planes did not sink but were covered with more natural atmosphireric precipitation indicating a building up of non melting surface. this refutes that greenland is melting?

Wow! We’ve got 17 years of data out of the last 10,000,000 years... we know everything. What I particularly love is how the melting ice is exposing farm ground and ancient buildings. Greenland wasn’t named Greenland because it was icy or white with snow... for Pete’s sake! They used to grow grapes there!
What I didn't see was any discussion of how much precipitation. snow and rain. falls on Greenland. I keep hearing that Greenland is losing ice and I don't see measurements of a thinning icecap as a result. So I wonder if we're being told the whole story? She tells us enough water since 2002, 15 years ago, to cover Australia knee deep. That's about an inch per year and Greenland is about one third the area of Australia so that would necessitate 3 inches per year coming from Greenland precipitation. And a quick internet search en.climate-data.org/location/132922/ says Greenland gets 30 or more inches (821 mm) of precipitation per year. Which would mean Greenland could be gaining ice. So that statistic isn't as dramatic as "...it would drown Australia knee deep..." leads us to believe. Looking at it another way knee-deep at about 18 inches would require 3 x 18 = 54 inches. You mean they can't measure nearly 5 feet of thinning on the Icecap? Yup! Put an ice cube in the micro-wave for 2 minutes and it comes out pretty much untouched.
She mentions the annual snowfall in the satellite image video of the ice sheet, with the overlaid trend graph showing mass loss and seasonal variation in ice sheet mass. And, no, you cannot be told the whole story of any topic in a TED talk - the point is to inspire interest in using your OWN brain on this topic, or on another topic that interests and inspires YOU.
@@bobpearsall7737 Thanks for the reply. Yes around the 2:20 mark precipitation is mentioned. Climate science is rife with scary scenarios and dramatic statements. "Ice loss that would have stunned a glaciologist 50 years ago" It seems that everything in Climate Science is "worse than previously thought" Google that phrase some time. Sea level according to the world's 1200+ tide gauges is rising and it has to be coming from somewhere and more icebergs calving into the sea than snow that falls is a good bet for a lot of it. She winds up talking about sea level rise in the next 80 years "...perhaps as much as one meter maybe more..." That's over 12 mm/yr or four times today's rate. Scary and dramatic that's for sure. One has to wonder when this acceleration is going to begin to happen.
She must have misspoke. I "rewound" the video three or four times to hear, "over the next 80 years, sea levels will rise at least 27 meters." She must have meant 27 inches... or 27 centimeters... or 27 percent of something unspecified... or 27 arc cubits... or?? Then she adds, "...perhaps as much as one meter." Okay... her clarification (perhaps as much as one meter) should get extra credit here.
I liked the tone and the factual delivery. No hot air, no cataclysmic predictions based on green religious beliefs, just science. This is what we do, this is what we found, this is what we're investigating, open questions, no hot headed conclusions without data. Really refreshing! (In every sense...)
@@stedavies241170 Why unlucky? She's basically not making any definite prediction about the future.

The Vikings farmed on Greenland. That was when there was a long warm period. Fast forward to my dad being stationed there in 1953-54. You could not grow crops there. There are and always have been weather cycles of warming and cooling. It is all controlled by sun spots and flares.

That is actually not true
Vikings miss named greeland and Iceland on purpose to confuse and thereby keep the secret
Iceland is green
Greenland is icey
Considering Denmark ,Norway , Sweden and Iceland are at lower latitudes than greenland why would they try to grow anything up there
The cycles you are talking about usually are between 30.000 and 100.000years (it might seem a lot but in geological periods it’s nothing)
The Viking were more like 1000 years ago
The 1 Km (1000 m) ice sheet in greeland looses 2 to 4 cm a year that’s around an inch and a half

Are you kidding yes? If you put something more dense than snow or even ice on such surface it will drown slowly during that time. That is why all ice cap polar bases are built like it on swamps. On the pillars! Go back to learn things properly. Very poor comment. Interesting subject but lack of understanding water/snow/ice physics.
FYI: After some calculations, in 10 years about 0,09% of the icesheet in Greenland has melted. Don't be mislead by graphs, the red doesn't mean gone.
Greenland icesheet: 2850 tera-tons | Amount melted: 2.5 tera-tons | Amount melted: less than a thousandth
Also measurements started in 2002, what about last 10,000 years?
Liar. When Manhattan is below sea level we might talk. Until then, you and ostriches are too alike.
This is all bullshit, easy to tell as soon as you see the NASA logo.

@rogerpattube I have her as my professor and she knows this topic in depth. She is actively researching that issue here at UB. There is proof that if that glacier is experiencing cracks and freezing and melting points are causing it to leak into the ocean than so are other glaciers as well.

An interesting presentation, it brought to mind cities that in ancient times were port cities and now they are hundreds of miles from any salt waters. We seem to have been here before.
The massive ice sheet has been GROWING not shrinking. Even Denmark which tracks this online has admitted this.
@@emsnewssupkis6453 IIRC that's ice that's in the water which doesn't much affect sea level. Ice melting on land is the big concern.
@@blindfaith8777 On Greenland, it is growing IN THE CENTER, not just the fringe.
So what was the ocean level in 1100AD, when the Vikings were still farming on Greenland? Can't scientists easily determine that, to give us an idea of what the sea level would be if most glacial ice was gone from Greenland?
Greenland was Eden. Valhalla.
There are castles in England which used to be at the waters edge in the middle ages. Now they are a couple of miles from the coast.
What I find interesting is that within the cooler water, the intermolecular attractions line up complex molecules ( such as polar proteins like RNA, DNA) and encourage the proper alignments for chemical reactions much, much better than the random high energy motion of molecules in a heated environment. Perhaps, the periods of glaciation have had greater impacts on the diversification of organic molecules and, perhaps, the evolution of life on this planet than the periods of warming? No idea - but this was my first thought on learning of the effects of glacial water cooling on molecular motion in published research. (Norwegian?)
Apparently Greenland ice mass (as well as Antarctic ice mass) has increased in mass since this talk was made, and sea levels have dropped according in both Greenland and New York, as they have cyclically in the past. Don't believe me, check the data. We have had 'emotional reactions' to periods of warming and periods of cooling in the past. Don't believe me, check the literature. Peace.

The earth's default state is "Ice Age."
There are brief remissions called "Interglacial periods."
No previous one has lasted as long as this one and it's risen to higher temps. with lots of ups and downs, than previous interglacials. The overall, meteorological power of the world system, beyond the ken of humans, utterly dwarves this puny CO2 upstart as "fart in the wind."

Carlos Nells there’s a documented Viking colony that lived in Greenland for nearly 100 years during a time of natural warming around 1200AD. The colony was abandoned because it got cold again and farming became unsustainable so the colony went back to Iceland. You can still see the remnants of the church and main hall foundations. There were also Inuit tribes living along the coast and they were very hostile toward the vikings.

Mine is a reply to the video as well. Please read mine and comment!!!
This video is a lie. NASA satellites say Greenland has a net gain of 30-150 gigatons and Antarctica has a net gain of 50-200 gigatons per year.
Greenland ice sheets would melt completely if it warmed 3degrees farenheit.
Do the math, thats 37.4 degrees farenheit. of course the ice sheets would melt completely.
Even the provenly fraudulent report by the ipcc (the report they publicly apologized for) says that at the most the world will rise 3-6 degrees farenheit in the next 100 years. Far from the 37.4 percent required to melt all the ice on the poles.
Not only that, but u.s. emissions are going down, despite leaving the Paris Accord, while Russia and China have no obligation to BEGIN placing policies to curb their emissions. While we payed for 60% of the Paris Accord.
Why is it they want u to quit burning gasoline, but they're letting China and Russia emit as much co2 as they want.
They are trying to take our energy Independence and make us week. They want us to give up the greatest system that has brought more people out of poverty and misery than any before it (including in countries around the world).
They are brainwashing u. Please, do the independent research and connect the dots before our great masterpiece of civilization is destroyed and raped.

The worst case. You dont need money for years.
How much water volume is over Greenland?
How much mm is it, if you put it into the world, into the oceans.
Subtract the water, which goes into the air, when heating up.
Heating up is the reason for melting.
So take this into acount.
@@newman5901 Your missing my point mate - climate change is global not local, Greenland doesn't exist in isolation does it? Incorporate the world's ice caps and surely you don't need precise calculation to know we'd have a significant issue.
And what happens to water when it goes into air? Evaporation turns liquid into gaseous form which, inevitably, turns back into liquid form. It's a finite process. The more liquid (and gas) from solid ice, the more floods.
Yup. NASA has no plans to move KSC!
Gee..... what a shock!!! There’s water under the ice.

Just because you just found out about aquifers in ice sheets, doesn't mean it hasn't been happening for millions of years. Although the "Two Year study" 2003-2005 by NASA, which took detailed elevations of the exterior of the ice sheet, seems to indicate a loss in ice mass, this is based on the outer size of the sheet, not its density. A new study by a Norwegian-led team used the ERS data to measure elevation changes in the Greenland Ice Sheet from 1992 to 2003 (11yrs), finding recent growth in the interior sections estimated at around six centimetres per year during the study period. Once again NASA takes a tiny bit of data, that fits their model best, and predicts all sorts of nonsense. ESA has had at least one working radar altimeter in polar orbit since July 1991, when ERS-1 was launched. ESA's first Earth Observation spacecraft was joined by ERS-2 in April 1995, then the ten-instrument Envisat satellite in March 2002. The result is a scientifically valuable long-term dataset covering Earth's oceans and land as well as ice fields - which can be used to reduce uncertainty about whether land ice sheets are growing or shrinking as concern grows about the effects of global warming. www.esa.int/Our_Activities/Observing_the_Earth/ERS_altimeter_survey_shows_growth_of_Greenland_Ice_Sheet_interior
Even just counting the melt it's a miniscule fraction of the total mass, that easily disappears into a margin of error.

"The aquifer water drives the crevasse all the way to the base of the ice sheet, a thousand meters below".
"The Greenland ice sheet is huge, the size of Mexico. And it's ice from top to bottom is two miles thick".
So...is the ice sheet thickness a thousand meters, or two miles??? BIG difference! (Unless the snow {aquifer} is over seven thousand feet.)
No like 2 miles is 3.2186 km so like in meters it would be 3218.6 m.
The name Greenland was given by the norwegian viking Erik "the Red" Thorvaldsen around 985 a.c. as he tried to allure settlers to move to the island from Iceland and Norway.
The climate in the southern regions at that time was mild ("green"), hence the name.

Ms. Poinar is wrong about the rise of sea level. It is rising at the rate of somewhere between 0.6 to a maximum of 1.2 mm per year. This is according to the U. S. Coast and Geodetic survey, which as been taking these measurements for the last 140 years. The U.S.C.D Survey is more accurate than satellite surveys and is the authority on sea level rise. I dare say this is one of the first sources Ms. Poinar should have checked. We are 1/5th of the way through Al Gore's 1998 predictions and the sea level hasn't risen 1 inch!
Very cool comfortable spring in Texas this year (2021), it's often 95 by now but we linger in the 80's with cooler evenings and mornings. I figure it's impossible to melt that much ice into ocean without causing temps to drop as well. I'm also figuring on a murderously hot summer when it finally gets here.
No it will not drop the temperatures it will raise them. He'll stop the North Atlantic conveyor current. What happens is it will stop removing the heat from the equator and transporting it up the planet. It will get way colder in the north and stay hotter at the equator. But that much water is a factor. But removing that conveyor belt of warm water will make so much eat at the equator that it won't make much difference on the temperature would be my guess. I mean of the water anyway up north. The volume of water itself will not lower the temperature it will actually prevent the planet from cooling itself like it does now.
Ice two miles thick covers all of Greenland. And it's lost so much ice, enough to cover all of Australia 2 feet deep! Well if Australia is 3.5x the size of Greenland, Greenland's ice must have diminished by over 7 feet! Doesn't seem like that is such a big impact on ice that was 10,000 feet thick.
A much simpler and more accurate method of determiming the amount of glacial loss is the hundreds of millions of years of geological record. The ice caps have grown to cover europe and even canada in 2 miles of ice thrn receded to zero ice cap over and over again throughout the history of earth with water.
Amazing presentation, thanks a lot :)

@@godsbeautifulflatearth Why sarcastic?
When the Vikings sailed to a large island which was lush and green they named it greenland and they lived there happily for three hundred years. Then it started to get colder and eventually it was completely frozen over so most of them left and headed back to Scandinavia! So don't panic about it melting now. Maybe we have sped up the process but it was due to happen anyway!

The reason why we did "nothing" for thousands of years before that is because there were barely any organised groups of people. We mostly lived in small hunter gather communities that only needed to survive. Then as circumstances changed we migrated, invented farming and developed civilizations around 10,000 years ago.

The Danish meteorological institute has data showing that the mass balance is positive not negative. That is to say that the mass of ice is increasing by approximately 350GT per year. This is the opposite of the data presented here - which is curious. How can two sets of data, apparently referring to the same phenomenon, yield such conflicting results?

And Iceland is nothing but grass ..

What a lot of people don't realize is that when the Norsemen (Vikings) reached Iceland it was winter and the land seemed relatively icy compared to the lands they knew: i.e. Denmark, Britain, and even Norway. When they reached Greenland it was mostly green. The icecap was relatively small compared to what it is now.
@@lloydzilinski4401 Not fully true, Ice cap in Greenland was almost the same, but Vikings hit cost line during short summer and saw green hills. They discover Iceland in it's most icy place (south east) and name it after it. However they may re-discover Iceland after suggestion that island was known to Celts from Ireland and Scotland before (6-8 century A.D.).

@basil fawlty en.wikipedia.org/wiki/Sea_level_rise
not vile... theyre just making fun of the obvious, the ice is on top of greenland... therefore the logical answer doesnt need an 8 minute video...
What's hidden under the Greenland ice sheet?....um....GREEN LAND?
Sometimes I venture to think they are melting the ice on purpose!
sky watcha they are.
Finally a smart person
Germany launched an artificial sun in 2018 and focused light can reach 3500 degrees on earth. Also look up Directed Energy Weapons DEW
The Democrats need the water to make more "Kool-Aid" for all the illegals coming across the border.
Are you serious? If you are it's just ignorance to evidence of climate change. You trust a qualified airline pilot or doctor (in an emergency) but don't trust authority if your life doesn't depend on it and it gets in the way of your opinion.
The rate of melting or flowing is more than likely directly proportional to the amount of ozone in the atmosphere, the ozone is like a hole in the atmosphere, allowing more uv rays to punch through our atmosphere, hence, heating up the oceans. Does a 1 degree (warmer) change make a difference in our climate??
Sort of a bad title because the answer is "Greenland".
@Grant Willetts True enough .
Canada & Northern states were covered in two mile thick ice which didn't seem to change sea/ocean levels.
If someone finds my car keys under there....I could use them. And my remote control
Damn you.
You beat me to my joke.
MELT THE ICE!!! I want to see what Greenland is SUPPOSED to look like! Maybe it will look like Iceland, then I could go there on vacation all the time.
Yes, and this will also create more land to build new buildings, businesses, houses, etc....People can resettle in the northern part of the country some day!!
My bet is an ancient bacteria that is highly contagious and deadly to humans. Be careful what you wish for!
@De mon It was misnamed. Basically, Greenland and Iceland should have swapped names. Or, Erik the Red was at best optimistic when naming it to try to convince others to come farm it with him. Every group/culture that we know of that ever lived there lived right on the coast, Vikings included. They had no choice but to live on the coast because the place is almost completely covered by that huge ice cap, which is white
Melting the ice is a really bad idea
2030: Scientists discover oil deep under Greenland's ice sheets...
America: *GreEn lAnD nEeDs dEmOcRacY*
It's already a democracy.
Who's here Aug 2019... Cuz I see more than 2017 when this was post... Hmmm Greenland on news, and many 2-3 year old vids of Greenland in my feed.
Global Warming Scam has been laid bare for all who have eyes to see.
I thought this was going to be a video about the Hiawatha impact crater and the younger dryas cooling period, what a disappointment.
No doubt!!
The sea level change has another implication that you don't hear discussed in the video, that enormous weight when redistributed results in a proportional shift in the underlying magma and this may have seismic implications on a global scale.
like big cities ?
say it aint so !!!
What about adding all that fresh water into the ocean? I remember something about the oceanic conveyor it could cause cooling in Europe? I will have to read up on this. Very well done!!!
George Sabol. Some scientists have said that the melting of the polar ice caps could change the direction or stop the golf stream which brings warmth from the Carribean area to Europe. This would result in Europe becoming colder. And I hope that doesn't happen or my home country Finland could become as cold as Siberia.
The earth's crust is NOT floating on a sea of magma
Paul Marchant. So you are just going to leave it there without giving any explenation as to why you think that?
And yes, the Earth's crust isn't just floating on a sea of molten rock because the borderline between the crust and magma layers isn't tgat easy to define. The rock just gets hotter and therefor softer the deeper you go. So saying that the crust is floating on a sea of magma gives a bit of a false image of the reality.
in 1945, a couple of p-38 airplanes were forced down due to weather on the surface of greenland. the planes remain ther today with the exception of one retreived well over 100 feet down. now, the planes did not sink but were covered with more natural atmosphireric precipitation indicating a building up of non melting surface. this refutes that greenland is melting?
Trouble is we don't know anything.
Tim Henry we know a great deal. We know the basic outlines, but the timelines are not totally clear. But it’s man-made carbon dioxide warming up the Earth. If we ever get to the point that the methane under ocean floor and the arctic tundra and the taiga melt, the atmosphere will have a large proportion of methane, and we all die.
@@Swift2001 We don't talk about man-made global warming anymore. Since we've been proven wrong on this, we need to ONLY use the term "Climate Change". Please stay within the reservation boundaries, James. Thanks.
@@Swift2001 Let's be clear. The earth will be fine.
The earth has been a lot warmer then now. One solor flair and we are dead anyway.
Maybe there are caves in the ocean floor that take in the melted ice. We know more about the moon than the ocean floor.
Kristin, you should stay away from Greenland. Your beauty, warmth and wonderfulness will melt the ice too fast for the world to react.
Wow! We’ve got 17 years of data out of the last 10,000,000 years... we know everything. What I particularly love is how the melting ice is exposing farm ground and ancient buildings. Greenland wasn’t named Greenland because it was icy or white with snow... for Pete’s sake! They used to grow grapes there!
What I didn't see was any discussion of how much precipitation. snow and rain. falls on Greenland. I keep hearing that Greenland is losing ice and I don't see measurements of a thinning icecap as a result. So I wonder if we're being told the whole story?
She tells us enough water since 2002, 15 years ago, to cover Australia knee deep. That's about an inch per year and Greenland is about one third the area of Australia so that would necessitate 3 inches per year coming from Greenland precipitation. And a quick internet search
en.climate-data.org/location/132922/
says Greenland gets 30 or more inches (821 mm) of precipitation per year. Which would mean Greenland could be gaining ice. So that statistic isn't as dramatic as "...it would drown Australia knee deep..." leads us to believe. Looking at it another way knee-deep at about 18 inches would require 3 x 18 = 54 inches. You mean they can't measure nearly 5 feet of thinning on the Icecap?
Yup! Put an ice cube in the micro-wave for 2 minutes and it comes out pretty much untouched.
@Charlie K Thanks for the reply.
She mentions the annual snowfall in the satellite image video of the ice sheet, with the overlaid trend graph showing mass loss and seasonal variation in ice sheet mass.
And, no, you cannot be told the whole story of any topic in a TED talk - the point is to inspire interest in using your OWN brain on this topic, or on another topic that interests and inspires YOU.
@@bobpearsall7737 Thanks for the reply. Yes around the 2:20 mark precipitation is mentioned. Climate science is rife with scary scenarios and dramatic statements. "Ice loss that would have stunned a glaciologist 50 years ago" It seems that everything in Climate Science is "worse than previously thought" Google that phrase some time. Sea level according to the world's 1200+ tide gauges is rising and it has to be coming from somewhere and more icebergs calving into the sea than snow that falls is a good bet for a lot of it. She winds up talking about sea level rise in the next 80 years "...perhaps as much as one meter maybe more..." That's over 12 mm/yr or four times today's rate. Scary and dramatic that's for sure. One has to wonder when this acceleration is going to begin to happen.
She must have misspoke. I "rewound" the video three or four times to hear, "over the next 80 years, sea levels will rise at least 27 meters." She must have meant 27 inches... or 27 centimeters... or 27 percent of something unspecified... or 27 arc cubits... or?? Then she adds, "...perhaps as much as one meter." Okay... her clarification (perhaps as much as one meter) should get extra credit here.
Well I see that I screwed up. The link above is to Greenland, Michigan.
Zeno Brothers Map of Greenland is very accurate. So we actually had a good idea before the ice started melting. Of course they won't talk about it.
3:20 You tell them Krisin, you have to get it wet.
🍆💦💦
I liked the tone and the factual delivery. No hot air, no cataclysmic predictions based on green religious beliefs, just science. This is what we do, this is what we found, this is what we're investigating, open questions, no hot headed conclusions without data.
Really refreshing! (In every sense...)
unluckily for us I do believe this lady is speaking the truth.
@@stedavies241170 Why unlucky? She's basically not making any definite prediction about the future. She's saying: "we need to study this more", which is really refreshing compared to the alarmist bullshit politicians and other power hungry monsters are using to manipulate us, without actually knowing or even caring about what's really going on.
She is one smart, cute science nerd. Thank you for this
Greenland has the most remote places on earth, and is the most manipulated by Humans from their distant homes.
Greenland, Brazilian forests, New Zealand, Venezuela and Iran. The places to watch in 2020.
"... What the smartphone has done for social media."
Unfortunately, this isn't quite the ringing endorsement she had hoped for.
Truly I am not surprised this was used as an analogy. I have seen someone similar use Tinder in a similar analogy.
Greenland asteroid strike triggered meltwater pulse 1A triggered rise in sea levels and sunk Atlantis.
If it did melt off, that would be great, I love it when spring melt comes back to Maine.
What an idiot sounds like after two years.
mind shaming is mean how dare you muhahahahaha
