@@shaymininfernape7088 We could, right now, but everyone would need to be on board, and everything we can do would need to be done within the next five years or so. That's obviously not going to happen, because the Wealth Class has paid developed nations' government officials to look the other way, and to keep Public Education, especially in the Sciences, at as low a level as possible, while simultaneously keeping wages lower than work's worth, so overworked people have no time to learn new things, no time to think about what they've learned, and no time nor extra money to act on what they've thought about. Us doing all we personally can is surely helping, but if only one in ten people is bothering to change their personal habits, clearly, that's not going to be enough. I guess that means you're right. We can't stop it, because most people refuse to try, for various reasons. A well-off woman once told me, rising oceans won't bother her in Colorado. I mentioned people moving inland, being displaced, and she said she'd just move to Alaska. I mentioned food shortages based on shifting growing regions, droughts, and floods, and she said we could just plant a lot more trees, and she could afford higher food prices. But what about everyone who can't afford to move, and pay more? She informed me, "That's their problem. I'm not going to be forced to change my life, and besides, I'llbe dead before most of that happens." 🙄 That was it.
Living in Kolkata, I can verify all of this to be true. Summers have become much hotter and unbearable in the past 15 years or so. And we have no more space to make green spaces in the city. If we indeed have to, we'll have to make use of more of the East Kolkata Wetlands, which is being repurposed for human benefit for the past 40 years or so, despite being the world's one of the largest and most important wetlands.
Sayak Chakraborty while I have also noticed summers are getting hotter we’re I live in the NYC metro area. Humans are really bad at think about long term trends and defining weather and climate. Lots of problems with climate deniers is that they focus too much on the now and not overall. Earths getting warmer overall while your still going to get extreme cold events, heat is overwound beating cold with extreme heat events being that much hotter. Global Summers as a whole and in most areas are getting hotter, using your personal experience is not always the best tool if you know what I’m saying :)
@no no not really the same ast to what op was talking about. climate change deniers tend to use one day/season variables as "proof" i.e. 'how can climate change exist when it snowed last wednesday???'
Well.... Covid-19 has done some good + the hole in the ozone has just already closed itself wayyyy sooner than scientist would have thought. It may finally going way better than we thought after all, and it's for the better. It doesn't mean we should stop the efforts though.
Aaronit0 I swear this Spring actually felt like Spring is meant to. L.A, NY, Detroit, and other metro areas have skies clear of pollution. Little to no haze.
@@Aaronit0 The ozone hole isn't related to global warming, it's an environmental concern that predates our concerns over climate change. The ozone hole has effectively closed long before the pandemic and it closed due to the Montreal Accord which is an international agreement to shift away from the use of fluorocarbons. Unfortunately, the changes in refrigerant uses specified in the accord actually increases the greenhouse effect so the changes in our refrigerant use that has resulted in the ozone hole closing has actually increased global warming.
A year after this video, we have had an extreme heat wave in the Pacific NW that caused a huge heat extreme not far from Vancouver BC, the hottest temperature ever recorded, followed just days later by a wildfire that wiped the nearest town off the map. I think we are already seeing more warming than was expected for a few years.
It was Lytton BC. Not the hottest temperature ever recorded, but rather the hottest temperature in the world on that day. It was the hottest Canadian temperature ever. South of Lytton was not as hot, but it was still in the 40s and was to me the second worst weather I was ever in. The sand storm in Egypt as was in was the worst. Over 500 people died due to the heat. The town was mostly burnt to the ground the following day.
@@arnehofoss9109 and this places gives you evidence that warming isn‘t taking place already? No it doesn’t, the hottest 10 Years on a global average scale, were all after 2000 (since we can meassure this)

we're just coming out of an ice age on a global time scale and people are freaking out about things getting a little warmer... there's basically no where that's so hot it'll burn you to death, but probably about half the world is cold enough for you to freeze to death.

Too. Damn. True. BUT..... the more we hope, the harder we work, the less we give up, the LESS "so screwed" we will be. And in THIS arena, tiny victories could mean habitable, instead of not. (I'm just trying not to give up, myself😢)
About 1:28 I'm not an expert, but I'd say some places will get quite a bit cooler. Where I live (Brazil) the coldest temperatures ever recorded in my city where in the last few years, and also the hottest temperatures. What some people don't get is that things wont just get hotter, they will get more caotic. People think that just because one specific place got colder than global warming is fake
danielffnando true, also weathers not climate. Yes you will definitely get lots of extreme cold events. But the extreme heat events will overwhelming out way the cold. Overall causing the planet to get warmer. Plus changes in the jet stream will do that to. Here in the Northeast, this year is still on track to be one of our warmest years on record it we happen to have a cold April and May. But because our winter was that much warmer. The overall average goes up for the year. Also while we froze in May, the Earths overall experience its 2nd Hottest April on record for 2020. So yup, you will still get extreme cold events but heat is happening more.
@Mr. M possibly but it’s likely the greenhouse effect would cancel it out. I doubt that would happen especially with record breaking heat in Europe recently.
I've noticed changes in my own hometown. When I was a kid we used to build snowmen and igloos and go sledding. We had cold snowy winters, and even when I was a kid I remember my parents and grandparents being concerned that the winters were growing more mild. It's been 3 years since anything froze over around here. If you want to do any snow sports you have to go up north even further. They get more and more slushy and rainy every year. The summers are even worse because we're in a really humid place, near a lot of industry. So we get 95 degrees and higher days with oppressing humidity and crazy rain and flooding. Makes me wonder what it will look like in another decade.
This is a scare mongering to tax people. Many places are seeing colder than normal temperatures. We are entering a Grand Solar minimum. Dont fall for mass media BS. People die from heat and cold all the time. Just choose wisely where you live. Climate has always been changing so dont expect everything to be the same when you were a kid. The climate fluctuates and it's got nothing to do with human activity. EDUCATE YOURSELF and stop falling for mass media BS
@@farrelco "Just choose wisely where you live" so in other words, you want 40% of the world population to set up a refugee camp in your backyard because they obviously won't be living in a place where the heat index is 74°C (165°F)

Also remember people: 2°C is a relatively good case scenario, and we have a lot to do to prevent any larger impact. Plus: the year 2100 is only an arbitrary point to look at. The effects will continue to develop, depending on our actions...
Therefore trying to fight it, reverse it or slow it down is futile exercise. The only reasonable way is to adapt. You can't win over the force of nature and the planet.

As Wendover so eloquently puts it: the Arctic is warming. That is not an assumption, a belief, a theory, or a political stance. That is an empirical fact based on empirical data.

Fantastic episode guys! We so often hear the shorthand version of these statistics on the news, so it's good to dig deeper and learn what it all really means.
With all due respect, as someone who lives about an hour south of Vancouver and has seen wildfire smoke so intense for the last 4 of 5 summers that our usually pristine sky rains ash a shorter ski season is the least of our problems.
The earth will not be destroyed. Human population on the other hand ... it will not go that well. Sad thing is that the ones from parts of the earth that are already hit by poverty and war , will also be the first to pay the price for the climate change. The last to go will be states with money an power. Wars for resources and agricultural land will decimate the population Even the most democratic and free states of the world will eat themselves when it comes to survival. I simply do not think that the world is capable to work together to save as many people as possible. Look at COVID 19. The first instinct was to panic and to only care about themselves.
What makes you think humans "destroy" Earth? Earth has survived much worse, like a collision with a planet the size of Mars. No, humans only change the face of Earth, destroying our own basis to live. Earth will carry on, with or without us.

Same. It feels like winter has been pushed back over the past four or five years. The only outlier was when the Arctic vortex made everything stupid cold. For context I'm in East Tennessee.
Same here, in NYC. Winters are extending into May over the past 3-5 years. We also seem to be inundated with an increasing amount of heavy rainfall that literally lasts 12-24 hrs without a break in the weather.
almost non-existent when I last visited Florida in 2014, apart from intense cold snaps that killed orange groves Western NY definitely had intense winters, they lasted the longest I've ever experienced, but they kept arriving & subsiding very late, sudden arrivals in December then no proper snow-melt until May in Kentucky, later & shorter winters, some dustings of snow in January & February, then not much but cool temperatures and hoodie-weather, no need for layers of clothing, let alone snow-shoes, until late April
It’s interesting watching this video a year after it was made as Vancouver has since experienced two devastating weather events in that time, including a record-breaking heatwave that killed 600 people (and sparked one of the province’s worst forest fire years on record) and then this fall a record-breaking rain event that flooded several communities and washed out the province’s highway system, displacing thousands of the province’s residents and causing supply chain issues leading to food and gas shortages. That highlights a few additional impacts from a world that is 2C warmer, except that we’re not even there yet, so things will only get worse.
Adam B yup, in fact most climate models predict a 3°C to 5°C rise in global temperatures by 2100 if we don’t act at all (which is likely). Just an idea on how hot that it, the last time Earth was 4°C warmer than today was more than 5 million years ago. Humans did not even walk the planet yet and by than we could warm the planet by that much in less than a century. Scary but preventable
Frodo Baggins it’s unlikely. While humans no doubt warming the planet, a Venus scenario is very unlikely. A 4° to 6° warming would be like the PETM. m.th-cam.com/video/ldLBoErAhz4/w-d-xo.html
D Barbarian image by 2100 or even 2050. A new study found that by 2070, more than 3 Billion people could be living in a world were the average annual temperature is 29°C or 84°F.

I find it easier to explain that the world is just like a human body. A rise of 1-2°C in body temperature would imply a fever, not every part of your body is 2°C warmer, it is just an estimate for all your body. But this increase already makes you feel sick. A 4°C increase would be catastrophic for our body, and it's the same for the Earth (this 4°C increase is the projection for the world without any climate action).
I guess we shouldn't mention that not one climate predictions has come to pass huh... Remember the "Sinking Maldive Islands" and all those poor people who were going to be homeless when their beloved island paradise sank beneath the man made sea level increase? First time they mentioned it was in 1987 when they started asking for money. What is the government of the Maldives doing today 33 years later? Investing in resort hotels on the islands. Because they haven't vanished beneath the waves because of the heartless actions of capitalism...as 'the models' predicted.
@@UmmCarl not one 'huh'? How about sea levels ARE rising; they just haven't risen to the catastrophic levels SOME were predicting, but in the past 10 years they have risen at double the rate of the previous century. Snow cover IS falling globally - satellite images confirm this. Ice sheets ARE shrinking - again, satellites. Glaciers likewise. Extreme weather events are increasing globally. The oceans have warmed by half a degree Celsius in 50 years - that is significant. Now, as you are a bit silly and have just plugged for the headline grabbing predictions that are the only ones people like you have heard tell of, I will give you the benefit of the doubt, but you still wont change your behaviour will you. Perhaps you should hit up the nearest anti-lockdown protest and get some fresh air - your brain will clearly benefit (though as with the consequences of your climate 'skepticism', others will have to pay the price for your silliness).
As a student studying climate science this is definitely important to know the effects of climate change. Just a reminder, while 2°C may not sound like a lot. When Earth was 2°C to 4°C cooler 20,000 years ago, most of North America was covered in ice several hundred feet thick. So 2°C warmer expect big impacts. Remember it’s the global Climate. So big impacts. Also at the current rate of warming which is 0.2° to 0.4° per decade, we will reach 2° by 2050 at the earliest. We’re also seeing extreme impacts due to global warming from 1.1°C warming, so image 2°C warming, or 3°, or 4°, or even 5°C by the end of this century and beyond. Human Civilization will struggle. More extreme weather, floods, droughts, heat waves and more. Global Warming is a big problem, while we could possibly adapt to it, why make it harder on ourselves? And while climate change never completely wiped out life on Earth. They have been responsible for mass extinction events nearly every time. I live in New Jersey. And ever since we got Sandy, I have been worried about another extreme hurricane and storm surge that could wipe out the Jersey shore thanks to rising seas. Just a meter rise will flood our whole shoreline. We need to listen to science and stop global warming
You need to stop listening to doomsday scientists and move further away from shoreline. Do you seriously think we can win over the incredible force of nature of this planet? By taxing ourselves to death? I have a bridge to sell you, great price.

Of course they won't have very long to really evolve. We humans might actually be a the last chance, for the earth to produce a technologically advanced space-faring society. Over the next 500 million to a billion years, the earth is going to under go a sort of reverse evolution; as it becomes harder for advanced life to thrive.

It seems unlikely that we could make the conditions on Earth worse than those."

One thing you didn’t mention about Vancouver is the huge wildfires in the summer. We started getting those the last few years and I’m pretty sure it has something to do with global warming. The wildfires eat up our forests, and the smog gets so thick the sun looks like a faint red smudge. We donate thousands to stop the wildfires each year, but they never really seem to be contained until the temperature drops. Imagine how much longer that would last if the temperature went up 2 degrees.
Also not mentioned were Richmond and Delta, parts of which are close to sea level now and may be prone to flooding in these scenarios. That's assuming that an earthquake hasn't already liquified them before they flood.
also not mentioned is that the northwest mostly doesnt have air conditioning leaving alot of people vulnerable during heatwaves. Lots of people died in vancouver this past summer. this video did not age well
The like/dislike ratio is pretty one sided. Did you just post this in anticipation of attention without any actual number of dislikes? Additionally, we know the climate has changed cyclically even before humans existed in any meaningful numbers.
We just saw how scientists were wrong by factor 50 predicting covid mortality rates and other stuff. So I guess if one scientist say 50 and the other says 1, both are correct, because science. OK BRO
I can't believe my hometown Vancouver is a feature in this video! It's a temperate rainforest. It's true! it rains a helluva lot. Flooding is a problem even now. I used to work in insurance. You will just see your premiums go up, or your insurer might offer less coverage. Some areas in the Metro Vancouver area could be completely flooded and submerged permanently. Not a pretty picture if our world warms 4 degrees more if nothing is done to avoid that. 2 degrees is the best chance scenario.

@@strawberrymilksamurai what myth? Just compare the cases of hotter areas like Indian subcontinent and Africa vs colder ones like USA and Europe, 2nd largest population in the world coupled with unhygienic people yet we have low cases and extremely high recovery rate comparatively
@@topg2820 we have low cases compared to countries that have been fighting it since long before it came to India (so we haven't had the time to reach their levels yet.)

Already, there have been 85,940 cases and 2752 deaths in India (there are most definitely too many more cases that haven't been reported. My friend's neighbourhood had a case like that.) By next month, it'll be far worse. If the heat was enough to get rid of the virus, we wouldn't have had this spike in infections. Like I said, the virus doesn't like the heat much, but it's not enough to damage it enough, and it's actually mutating.

Winter starts much later now and summers are getting so hot! Kelowna Canada gets close to 50 degrees in early summer now too, same province as vancouver as mentioned in the video
In Manitoba, one of the largest garden nurseries here put out a report on how their inventory has changed in the last 40 years. They now are able to grow about 50 species of plant that they couldn't before. When you consider that each species has hundreds of varieties, that is an enormous change. We are also seeing species of insect here that previously could not survive the winter. Some are venomous, and I'm not too happy about that.
Hospitals in Phoenix AZ have been overwhelmed with people suffering 2nd and 3rd degree burns from touching metal surfaces during the current heat wave (July 2023).
Just a year and some months after this video: The Vancouver heat wave prediction came true earlier and more intense than expected, having killed people and obliterated entire villages due to wildfires.
In the mountains surrounding my city, I noticed that progressively as each year went by, the snow cover decreased. In around say 2016, most of the mountain was covered in white. In 2017 there was a mega-storm that blanketed the entire mountain in complete white. Throughout the remainder of the 2010s, the snow cover was generous and large. Most of them lasted well into August-September. Now, in 2022, the mountains have been snow-free since March. The snow that covers the mountain went from just above the base to halfway and appears in little sprinkles rather than full covers of snow. Our dams are in jeopardy too. I'm scared for the future.
People tend not to feel very bothered by 'just 2C degrees' largely because explanations usually involve places that are thousands of miles away, and because they deal with individual cases of the effect of temperature when they should be emphasising that this is an average change representing the Earth's surface temperature as a whole dynamic *system*. Explainers like Hank, should, therefore be asking people to think how they would feel with a 2C rise in *body temperature*: NOT how 2C extra would feel to the outside of their bodies! We can, up to a point, keep our core temperature down by sweating, and by diverting more blood toward or away from the surface. So far, most of us are still living in places where this works. 2C higher, and Florida residents may only be able to go out at night (by boat if their homes are under water). The Earth, also, can maintain its average 'body temperature', by evaporating water, melting ice, and stirring up air and ocean currents, in a similar way to the way our bodies keep to 37C. We can get very ill if our core temperature rises to just 39C. 'Just' 2C warmer. Unfortunately, the Earth's cooling system is failing fast, and the temperature is rising, and is already at what would be cause to see the doctor, if it was one of us. The melting ice is the very serious warning, because that is the planet's air conditioning working overtime. Unlike our own household air conditioning, our home planet has no back up supply of ice to cool the air with when its all gone. The Earth already has a fever: what's it going to be like without the air conditioning, and with no doctor to call on? Whenever 'explainers' talk about climate change, they should try to have a picture like this one behind them: i.pinimg.com/originals/69/e3/77/69e377c5c9ba724d29eb2162bca0a279.jpg
Personally, I find that analogy lacking in persuasive power. Stick to facts. This presentation from Hank was exactly what I find helpful. Adding in an analogy like that just makes it seem like the actual facts aren’t strong enough so you had to try to find other ways to shore up the argument.
As you can see from the reply above, to many people, pure science is not enough. Scientists themselves must share some of the blame for this, because they have, over decades, singularly failed to inform the public of the difference between heat energy ('cause'), and temperature ('effect'). They chose to use a most difficult indicator to prove, when they chose to emphasise the thermometer readings while failing to explain that temperature is not heat, and global warming is about energy: not small movements of mercury in a tube. While the world's media was arguing endlessly whether the mercury level was rising or falling and who's fault it was, icebergs the size of whole countries were breaking away from Antarctica, and mountain glaciers and Arctic sea ice were disappearing faster than predicted with every successive attempt to keep track! Like Nelson: We've had our telescope to our blind eye, so we can say: "I see no ships."
Me, as a Canadian hearing Vancouver described as "cold": Oh, that's adorable! XD And, for those who are worried about the targets and whether or not we'll make it, remember that 100 companies are responsible for 71% of all greenhouse gas emissions. All that stands between us and a wonderful, habitable future is 100 companies! The only thing that's needed is public will! :D
One thing I've noticed in Vancouver, just over the last 20-30 years, is that the temperate climate has been increasingly skewing towards the more extreme weather patterns. Back in the 90's it seemed like it'd rain almost every day, but in more recent years it seems to be raining less. That being the less extreme end, however over the last decade its become common-place for us to experience a drought in the summer anywhere from a month to ~50 days. On the other end the winters while still being relatively mild, it has seemed that the winter temperatures and weather have been lasting longer year by year. Maybe I'm just noticing these weird weather patterns more these days than when I was younger, but it does feel like the temperate climate of Vancouver is losing the battle these days.
Oh, how about what is happening right now instead of after a 2 degrees increase in global temperature? I'm from Bangladesh and actually lucky enough to not be living in low-lying areas that have already been flooded because of climate change. Millions of people have already migrated and millions are migrating even now. The way farmers and vegetation have been affected cannot be overstated. Most of the people moving are moving from their own land to places where they will probably have to rent or live on the streets because these people tend to be from very low-income families. One of our only islands with coral reefs, St Martin, is already at risk. The Sundarban that's shown in the video here? Yeah, part of that is here and it is already facing a lot of issues. We have been talking about the entire country of Bangladesh just... slowly dying for years now. At least 20y years now. It's pretty telling when the biggest dream we have as a generation (the ones of us who know) is to move abroad. Which most of us won't. We'll just die, which is okay I guess.

Here they are all the gasses: en.wikipedia.org/wiki/Atmosphere_of_Earth Try to figure out why it is so little methane in the air! (Tips: It turns in to water vapor and Co2!)
This came out 3 yrs ago.. now what is the reasoning for hope when you can’t tell me one thing we’ve done in those 3 yrs.. let alone since the 80’s when we were first alerted of this issue?
We really need to start upgrading and expanding our nuclear power infrastructure ASAP. It seems foolish to wait for energy storage technology to catch up and make renewables powerful enough to power our cities. We already have functioning 0% CO2 emitting fission plants, and the newer generation plants that can be built have even fewer flaws than our existing ones. Refusing to build more nuclear because people thousands of years from now might have to deal with the radioactive waste is kinda idiotic when we might not even make it that far with the path we're heading down now. Stop being stubborn and ignorant, build the damn Fission plant.
Mr. M but your guaranteed constant power. Solar and wind aren’t reliable because you have to wait for the sun and the wind. Besides solar farms are huge and destroy ecosystems. If your going to destroy the environment you might as well make the most of it.
@Mr. M you're not wrong but in the long run nuclear will have the least impact on the environment afaik. Renewables are great but require very specific conditions to be met and solar and wind farms have a massive impact on the local environment. I don't think we need to discuss flooding of nearby land when we build dams lol. Basically everything we do has an impact at this point 🤷♂️
We also need to be funding hot fusion research! They know how to do it but we just need the research to get there. It would get rid of basically all the problems with moder nuclear plants. It's a big investment, but I think it's worth it.
@@aquaticborealis4877 As Lord Farquahar said: "A lot of people will die, but that's a price I'm willing to pay". That's the sad truth - and has been since we started banging rocks together.
Bad stuff. Ironically for me I retired back to Ontario after working 15 years in Vancouver & biking 120,000 km in the Fraser Valley and I looked forward to Ontario sunny summers with the bitter winters. But June 2021 that huge anti-cyclone that made a deadly sunny heat dome there brought endless cloud, rain, humidity & mosquitoes to Sunny Sundrige.
Best way to look at it: no matter how bad we make it, even if we cause global temperature averages to soar by 10 degrees in 10 years, the earth will still be here and so will life. Humans, not so much. We'll go extinct and the earth will begin a transition back to normalcy. It's not the earth that's doomed, it's the people.
Jarle Skogly uhhh probably During the Late Permian 240 million years ago during the great dying extinction, volcanic activity rose Earths temperature by 10°C and that wiped out 98% of life on Earth. Humans are warming the planet faster than that. We could reach 10°C warming by 2200. While we maybe good survive a 4°C warming at 10° it’s hard to see us survive unless technology improves greatly.
Aeturnalis while Earth itself is fine, humans, yes, will suffer, but also other life forms, for example Amphibious are dying out I’m pretty sure 800x faster than natural. Life will find a way. But barely. You can see this video on the 6th mass extinctions m.th-cam.com/video/z9gHuAwxwAs/w-d-xo.html Scientist also believe were in a new Epoch and no longer in the Holoence or the Quaternary Period.

Scishow videos are so enjoyable with Hank hosting, everyone else is irritating and make you close the video no matter how interesting the topic could be. Thank you Hank !
The problem with the Gulf Stream is even if it stops, because humans are adding so much greenhouse gasses, the Earth will probably still be warming, maybe a slight cooling in Europe but Apart from that, greenhouse gases may still out way an AMOC mini ice age.
As the planet breaks into WWIII due to conflicts over freshwater & other critical resource scarcity... well, the loss of revenue from ski tourism will be the least of your worries.
The most important thing people must understand when it comes to climate change and seemingly small numbers like 2°C: The amount of energy it took to get there. Can you please make a video showing the scale of things we are talking about? Like, if you take a small pot with 1L of water and put a thermometer and an immersion heater or somthing in it, powered that immersion heater with an ergometer and measured how long it would take to heat the water by 2°C. Then you do the same thing with a bucket. Then with a large bucket. Then with a swimming pool. This would likely take anywhere from 20 to 500 people and immersion heaters to even register ( I have no idea how to calculate this properly :( ). And then you ask the question "so how much energy do you think is needed to warm up the entire ocean by 2°C?" and make them understand that there now is the combined energy of 20-500 completely exhausted human beings in this water. People need perspective to grasp these numbers. Show them actual maps of how much their hometowns will be flooded or anything they can grasp and understand.
Born and raised south of Vancouver in Bellingham, and Mt. Baker's snow pack hasn't been good for years. The ski seasons have already shortened and "good" days are rarer. When growing up there was a beautiful starfish population in Bellingham Bay, all gone (this was from some blight or disease that spread because of climate change). Forest fires have also become part of the summer season in much of the PNW now and we can expect summers with a week or more of smokey air. Heat waves are also beating records every year like Salem got to 117f/47c and Portland 114f/46c last summer. A wild thing people don't mention too often is how the pnw may become a haven for ecological refugees as climate change may not have as extreme of an impact here compared to some places that may experience more desertification and flooding. Whoo!
I biked the 316 km round trip Vancouver B.C. (not Bellingham) to Artist Point (my thumbnail) & back 23 times 2008-2015 and the ditch stream alongside SR542 on the final 18 km of climb where I always soaked my feet was all dried up in one of the later years. I really saw a drying up in summer from 2008 to 2015.
Great video. Ty. It would be informative to update this topic every few years as we learn/experience more such the current effect of climate change on Colorado River and its intensifying impact of the water supply on 10s of millions of people, agricultural belt and industry.
Rain period changed in my city. Noramlly, the city would get extreme rain in april, usually mid-april and at the end of the month. April was dry, farmers were sad as the river was dry. Then Bulgaria opened the dam to let some water out which tripled the water in river, not flooding this time thanks to a recently built canal and then rain fall that had to be in april happened in may. So, even local changes can be observed. Also winters are more extreme, by extreme i mean it is either no snow or -20 celsius and snow up to knee...
People don't get: It's the ENTIRE planet, by 2 degrees. Do you know how much energy it would take to heat the entire surface of the only world/home we have truely ever known? That's. A lot of energy.
I think the fact that there will be some benefits is largely ignored. We can project and guess. But either way we're going to have to learn to live with warming or cooling climates.
Yes and no. Global Warming can help grow plants in locations further north but also turns current farm land into deserts and caused extreme weather and droughts and floods causing farming to be impossible
The increased rain won't be everywhere. Some places will be drier - some much drier. Most of the rain that falls will happen during increasingly-extreme weather events. It won't help a gardener (or farmer) much to grow their plants when one (variable) day per year experiences 60 inches of downpour, and there's no precipitation at all for the next year. Increased temperature helps many plants grow - but only to a point. Once it gets over 40C (104F), plants start dying out pretty quickly. The variability is what will kill you. Average temps may be up only 2C/3.8F, which might not matter to much of the temperate zone, but if you have occasional 45C/110F heatwaves of 3-4 days, the rest of the time won't matter a lot.
I feel like Hank should've mentioned it and possibly even linked his personal video (from Hank's Channel) on it but when people say +2C, they mean +2C by 2030. All the effects Hank lists are what would happen at +2C. But when we reach +2C by 2030 that's not the end of the warming, even if we stopped all human inputs to climate change the moment we hit +2C, it is still projected that we will be seeing +5C at ~2100. This video shows how serious it is at +2C, imagine how serious it would be at +5C.
I live in germany and the last few (3-5) years we had little to no snow. The last two years less than a week. Whereas in my childhood it was common for snow to last for months.
Such videos on climate change are so rare. You actually explain why and how this is important, without shitting on capitalism or industrialisation, or being hyperbolic about the results.

@@shaymininfernape7088 We could, right now, but everyone would need to be on board, and everything we can do would need to be done within the next five years or so. That's obviously not going to happen, because the Wealth Class has paid developed nations' government officials to look the other way, and to keep Public Education, especially in the Sciences, at as low a level as possible, while simultaneously keeping wages lower than work's worth, so overworked people have no time to learn new things, no time to think about what they've learned, and no time nor extra money to act on what they've thought about. Us doing all we personally can is surely helping, but if only one in ten people is bothering to change their personal habits, clearly, that's not going to be enough. I guess that means you're right. We can't stop it, because most people refuse to try, for various reasons.
A well-off woman once told me, rising oceans won't bother her in Colorado. I mentioned people moving inland, being displaced, and she said she'd just move to Alaska. I mentioned food shortages based on shifting growing regions, droughts, and floods, and she said we could just plant a lot more trees, and she could afford higher food prices. But what about everyone who can't afford to move, and pay more? She informed me, "That's their problem. I'm not going to be forced to change my life, and besides, I'llbe dead before most of that happens." 🙄 That was it.
Living in Kolkata, I can verify all of this to be true. Summers have become much hotter and unbearable in the past 15 years or so. And we have no more space to make green spaces in the city. If we indeed have to, we'll have to make use of more of the East Kolkata Wetlands, which is being repurposed for human benefit for the past 40 years or so, despite being the world's one of the largest and most important wetlands.
Sayak Chakraborty while I have also noticed summers are getting hotter we’re I live in the NYC metro area. Humans are really bad at think about long term trends and defining weather and climate. Lots of problems with climate deniers is that they focus too much on the now and not overall. Earths getting warmer overall while your still going to get extreme cold events, heat is overwound beating cold with extreme heat events being that much hotter.
Global Summers as a whole and in most areas are getting hotter, using your personal experience is not always the best tool if you know what I’m saying :)

Well.... Covid-19 has done some good + the hole in the ozone has just already closed itself wayyyy sooner than scientist would have thought. It may finally going way better than we thought after all, and it's for the better.

I swear this Spring actually felt like Spring is meant to. L.A, NY, Detroit, and other metro areas have skies clear of pollution. Little to no haze.
we should beware of pathological science.
@@Aaronit0 The ozone hole isn't related to global warming, it's an environmental concern that predates our concerns over climate change. The ozone hole has effectively closed long before the pandemic and it closed due to the Montreal Accord which is an international agreement to shift away from the use of fluorocarbons. Unfortunately, the changes in refrigerant uses specified in the accord actually increases the greenhouse effect so the changes in our refrigerant use that has resulted in the ozone hole closing has actually increased global warming.
yeah, this whole framing of this video is psychotic.
A year after this video, we have had an extreme heat wave in the Pacific NW that caused a huge heat extreme not far from Vancouver BC, the hottest temperature ever recorded, followed just days later by a wildfire that wiped the nearest town off the map. I think we are already seeing more warming than was expected for a few years.
And some places was colder than normal? th-cam.com/video/E9SbbtOSV9M/w-d-xo.html and th-cam.com/video/tvrp-poDErc/w-d-xo.html
It was Lytton BC. Not the hottest temperature ever recorded, but rather the hottest temperature in the world on that day. It was the hottest Canadian temperature ever. South of Lytton was not as hot, but it was still in the 40s and was to me the second worst weather I was ever in. The sand storm in Egypt as was in was the worst. Over 500 people died due to the heat. The town was mostly burnt to the ground the following day.

What some people don't get is that things wont just get hotter, they will get more caotic. People think that just because one specific place got colder than global warming is fake
danielffnando true, also weathers not climate. Yes you will definitely get lots of extreme cold events. But the extreme heat events will overwhelming out way the cold. Overall causing the planet to get warmer. Plus changes in the jet stream will do that to. Here in the Northeast, this year is still on track to be one of our warmest years on record it we happen to have a cold April and May. But because our winter was that much warmer. The overall average goes up for the year. Also while we froze in May, the Earths overall experience its 2nd Hottest April on record for 2020. So yup, you will still get extreme cold events but heat is happening more.
True. Hence why some people have advocated stopping the usage of the term "Global Warming" in favor of "[Anthropologic] Climate Change".
@@moondust2365 but it’s still global warming. At least technically.
@Mr. M possibly but it’s likely the greenhouse effect would cancel it out. I doubt that would happen especially with record breaking heat in Europe recently.
So, you should know what a cloudy sky means about frosts
Why all those people just do not mention vapour is the biggest among all greenhouse gases?
I've noticed changes in my own hometown. When I was a kid we used to build snowmen and igloos and go sledding. We had cold snowy winters, and even when I was a kid I remember my parents and grandparents being concerned that the winters were growing more mild.
It's been 3 years since anything froze over around here. If you want to do any snow sports you have to go up north even further.
They get more and more slushy and rainy every year.
The summers are even worse because we're in a really humid place, near a lot of industry. So we get 95 degrees and higher days with oppressing humidity and crazy rain and flooding.
Makes me wonder what it will look like in another decade.
This is a scare mongering to tax people. Many places are seeing colder than normal temperatures. We are entering a Grand Solar minimum. Dont fall for mass media BS.

Same. It feels like winter has been pushed back over the past four or five years.
The only outlier was when the Arctic vortex made everything stupid cold.
For context I'm in East Tennessee.
Same here, in NYC. Winters are extending into May over the past 3-5 years. We also seem to be inundated with an increasing amount of heavy rainfall that literally lasts 12-24 hrs without a break in the weather.
almost non-existent when I last visited Florida in 2014, apart from intense cold snaps that killed orange groves
Western NY definitely had intense winters, they lasted the longest I've ever experienced, but they kept arriving & subsiding very late, sudden arrivals in December then no proper snow-melt until May
in Kentucky, later & shorter winters, some dustings of snow in January & February, then not much but cool temperatures and hoodie-weather, no need for layers of clothing, let alone snow-shoes, until late April
It’s interesting watching this video a year after it was made as Vancouver has since experienced two devastating weather events in that time, including a record-breaking heatwave that killed 600 people (and sparked one of the province’s worst forest fire years on record) and then this fall a record-breaking rain event that flooded several communities and washed out the province’s highway system, displacing thousands of the province’s residents and causing supply chain issues leading to food and gas shortages. That highlights a few additional impacts from a world that is 2C warmer, except that we’re not even there yet, so things will only get worse.
2 degrees is basically the best case scenario
Adam B yup, in fact most climate models predict a 3°C to 5°C rise in global temperatures by 2100 if we don’t act at all (which is likely). Just an idea on how hot that it, the last time Earth was 4°C warmer than today was more than 5 million years ago. Humans did not even walk the planet yet and by than we could warm the planet by that much in less than a century. Scary but preventable
imagine we do 4 or even 6, the planet might end up like venus.
Frodo Baggins it’s unlikely. While humans no doubt warming the planet, a Venus scenario is very unlikely. A 4° to 6° warming would be like the PETM.

When Earth was 2°C to 4°C cooler 20,000 years ago, most of North America was covered in ice several hundred feet thick. So 2°C warmer expect big impacts. Remember it’s the global Climate. So big impacts. Also at the current rate of warming which is 0.2° to 0.4° per decade, we will reach 2° by 2050 at the earliest. We’re also seeing extreme impacts due to global warming from 1.1°C warming, so image 2°C warming, or 3°, or 4°, or even 5°C by the end of this century and beyond. Human Civilization will struggle. More extreme weather, floods, droughts, heat waves and more. Global Warming is a big problem, while we could possibly adapt to it, why make it harder on ourselves? And while climate change never completely wiped out life on Earth. They have been responsible for mass extinction events nearly every time.
I live in New Jersey. And ever since we got Sandy, I have been worried about another extreme hurricane and storm surge that could wipe out the Jersey shore thanks to rising seas. Just a meter rise will flood our whole shoreline. We need to listen to science and stop global warming
You need to stop listening to doomsday scientists and move further away from shoreline. Do you seriously think we can win over the incredible force of nature of this planet? By taxing ourselves to death? I have a bridge to sell you, great price.
The last ice age wasn’t 2-3 C colder than today.
@@e3498-v7l we do have an effect on the climate. We measure it. You cannot deny climate change and humanity's role in accelerating it. Its a problem that has been created over 10 generations and will not be solved unless we make the move towards becoming a class II civilization and terraform earth to a healthier environment.
The rich countries can adapt to it, partly. The poor ones....

Well no, not by taxes.
But if we could get rid of all the idiotic trumptard supporters we could get off fossil fuels, increase jobs, AND save a shitload of money all at the same time......
While I consider anyone who supports any party to be a dumbass, we don't need to tax the dems to get them to switch.
They understand that fossil fuels are poisoning literally everything and that renewables are cheaper and provide many more jobs, while also getting a lot less in subsidies than fossil fuels do.

Of course they won't have very long to really evolve. We humans might actually be a the last chance, for the earth to produce a technologically advanced space-faring society. Over the next 500 million to a billion years, the earth is going to under go a sort of reverse evolution; as it becomes harder for advanced life to thrive.

In the END it can not go well. Some say the earth dies from lack of Co2 and we all die. Some million years later the sun eats us and explode. Some billion years in the future. Before that we might get some rocks from space. Like before when 80% of all species got extinct. Actually that made it possible for us to develop. Some think that was a disaster.

One thing you didn’t mention about Vancouver is the huge wildfires in the summer. We started getting those the last few years and I’m pretty sure it has something to do with global warming. The wildfires eat up our forests, and the smog gets so thick the sun looks like a faint red smudge. We donate thousands to stop the wildfires each year, but they never really seem to be contained until the temperature drops. Imagine how much longer that would last if the temperature went up 2 degrees.
Also not mentioned were Richmond and Delta, parts of which are close to sea level now and may be prone to flooding in these scenarios. That's assuming that an earthquake hasn't already liquified them before they flood.
also not mentioned is that the northwest mostly doesnt have air conditioning leaving alot of people vulnerable during heatwaves. Lots of people died in vancouver this past summer. this video did not age well
The dislikes are people that insist on trusting their feelings instead of the facts of science.

The like/dislike ratio is pretty one sided. Did you just post this in anticipation of attention without any actual number of dislikes? Additionally, we know the climate has changed cyclically even before humans existed in any meaningful numbers.
All doomsday predictions have failed. All of them
We just saw how scientists were wrong by factor 50 predicting covid mortality rates and other stuff. So I guess if one scientist say 50 and the other says 1, both are correct, because science. OK BRO

I can't believe my hometown Vancouver is a feature in this video! It's a temperate rainforest. It's true! it rains a helluva lot. Flooding is a problem even now. I used to work in insurance. You will just see your premiums go up, or your insurer might offer less coverage.
Some areas in the Metro Vancouver area could be completely flooded and submerged permanently. Not a pretty picture if our world warms 4 degrees more if nothing is done to avoid that. 2 degrees is the best chance scenario.

@@topg2820 if you're talking about the coronavirus, heat being fatally harmful to it is actually a myth. Heat doesn't affect it much (even though the proteins sticking out of it are much more susceptible to heat than to cold, it's not enough to stop it), and the cases have been consistently rising alarmingly
@@strawberrymilksamurai what myth? Just compare the cases of hotter areas like Indian subcontinent and Africa vs colder ones like USA and Europe, 2nd largest population in the world coupled with unhygienic people yet we have low cases and extremely high recovery rate comparatively
@@topg2820 we have low cases compared to countries that have been fighting it since long before it came to India (so we haven't had the time to reach their levels yet.) But the infection rate is increasing alarmingly, because a huge group of people are not maintaining hygiene and social distancing. Already, there have been 85,940 cases and 2752 deaths in India (there are most definitely too many more cases that haven't been reported. My friend's neighbourhood had a case like that.) By next month, it'll be far worse. If the heat was enough to get rid of the virus, we wouldn't have had this spike in infections. Like I said, the virus doesn't like the heat much, but it's not enough to damage it enough, and it's actually mutating. I read there have been new cases in China and USA where people are showing symptoms that were not there before in patients, like lesions on the skin.

Tbh I think we have made huge changes already. I live in canada, the province I live in use to get 6ft of snow, now we usually get close to 2-3ft and way more ice. Winter starts much later now and summers are getting so hot! Kelowna Canada gets close to 50 degrees in early summer now too, same province as vancouver as mentioned in the video
In Manitoba, one of the largest garden nurseries here put out a report on how their inventory has changed in the last 40 years. They now are able to grow about 50 species of plant that they couldn't before. When you consider that each species has hundreds of varieties, that is an enormous change. We are also seeing species of insect here that previously could not survive the winter. Some are venomous, and I'm not too happy about that.

We used to have ~30cm of snow each year. Last year and this year the snow has steadily over the years dropped down to 0cm.
Where I live it has always varied. Some years a lot... some years a little. By my experience I can't say I've noticed any real changes in my life.
@@cgaccount3669 Over here it's been crazy, tho how much things change specifically at some location has a lot of factors
In the mountains surrounding my city, I noticed that progressively as each year went by, the snow cover decreased. In around say 2016, most of the mountain was covered in white. In 2017 there was a mega-storm that blanketed the entire mountain in complete white. Throughout the remainder of the 2010s, the snow cover was generous and large. Most of them lasted well into August-September. Now, in 2022, the mountains have been snow-free since March. The snow that covers the mountain went from just above the base to halfway and appears in little sprinkles rather than full covers of snow. Our dams are in jeopardy too. I'm scared for the future.
“Cold” winters in Vancouver? Rest of Canada all had a collective laugh at that.

People tend not to feel very bothered by 'just 2C degrees' largely because explanations usually involve places that are thousands of miles away, and because they deal with individual cases of the effect of temperature when they should be emphasising that this is an average change representing the Earth's surface temperature as a whole dynamic *system*.
Explainers like Hank, should, therefore be asking people to think how they would feel with a 2C rise in *body temperature*: NOT how 2C extra would feel to the outside of their bodies!
We can, up to a point, keep our core temperature down by sweating, and by diverting more blood toward or away from the surface. So far, most of us are still living in places where this works. 2C higher, and Florida residents may only be able to go out at night (by boat if their homes are under water).
The Earth, also, can maintain its average 'body temperature', by evaporating water, melting ice, and stirring up air and ocean currents, in a similar way to the way our bodies keep to 37C. We can get very ill if our core temperature rises to just 39C. 'Just' 2C warmer.
Unfortunately, the Earth's cooling system is failing fast, and the temperature is rising, and is already at what would be cause to see the doctor, if it was one of us. The melting ice is the very serious warning, because that is the planet's air conditioning working overtime. Unlike our own household air conditioning, our home planet has no back up supply of ice to cool the air with when its all gone. The Earth already has a fever: what's it going to be like without the air conditioning, and with no doctor to call on?
Whenever 'explainers' talk about climate change, they should try to have a picture like this one behind them:
i.pinimg.com/originals/69/e3/77/69e377c5c9ba724d29eb2162bca0a279.jpg
Spamlet Spamley Thanks for this analogy!
Personally, I find that analogy lacking in persuasive power. Stick to facts. This presentation from Hank was exactly what I find helpful. Adding in an analogy like that just makes it seem like the actual facts aren’t strong enough so you had to try to find other ways to shore up the argument.
As you can see from the reply above, to many people, pure science is not enough.
Scientists themselves must share some of the blame for this, because they have, over decades, singularly failed to inform the public of the difference between heat energy ('cause'), and temperature ('effect'). They chose to use a most difficult indicator to prove, when they chose to emphasise the thermometer readings while failing to explain that temperature is not heat, and global warming is about energy: not small movements of mercury in a tube.
While the world's media was arguing endlessly whether the mercury level was rising or falling and who's fault it was, icebergs the size of whole countries were breaking away from Antarctica, and mountain glaciers and Arctic sea ice were disappearing faster than predicted with every successive attempt to keep track!
Like Nelson: We've had our telescope to our blind eye, so we can say: "I see no ships."
Me, as a Canadian hearing Vancouver described as "cold": Oh, that's adorable! XD
And, for those who are worried about the targets and whether or not we'll make it, remember that 100 companies are responsible for 71% of all greenhouse gas emissions. All that stands between us and a wonderful, habitable future is 100 companies! The only thing that's needed is public will! :D
One thing I've noticed in Vancouver, just over the last 20-30 years, is that the temperate climate has been increasingly skewing towards the more extreme weather patterns. Back in the 90's it seemed like it'd rain almost every day, but in more recent years it seems to be raining less. That being the less extreme end, however over the last decade its become common-place for us to experience a drought in the summer anywhere from a month to ~50 days. On the other end the winters while still being relatively mild, it has seemed that the winter temperatures and weather have been lasting longer year by year. Maybe I'm just noticing these weird weather patterns more these days than when I was younger, but it does feel like the temperate climate of Vancouver is losing the battle these days.
Global weirding.
Oh, how about what is happening right now instead of after a 2 degrees increase in global temperature? I'm from Bangladesh and actually lucky enough to not be living in low-lying areas that have already been flooded because of climate change. Millions of people have already migrated and millions are migrating even now. The way farmers and vegetation have been affected cannot be overstated. Most of the people moving are moving from their own land to places where they will probably have to rent or live on the streets because these people tend to be from very low-income families. One of our only islands with coral reefs, St Martin, is already at risk. The Sundarban that's shown in the video here? Yeah, part of that is here and it is already facing a lot of issues.
We have been talking about the entire country of Bangladesh just... slowly dying for years now. At least 20y years now. It's pretty telling when the biggest dream we have as a generation (the ones of us who know) is to move abroad. Which most of us won't. We'll just die, which is okay I guess.

We really need to start upgrading and expanding our nuclear power infrastructure ASAP. It seems foolish to wait for energy storage technology to catch up and make renewables powerful enough to power our cities. We already have functioning 0% CO2 emitting fission plants, and the newer generation plants that can be built have even fewer flaws than our existing ones. Refusing to build more nuclear because people thousands of years from now might have to deal with the radioactive waste is kinda idiotic when we might not even make it that far with the path we're heading down now. Stop being stubborn and ignorant, build the damn Fission plant.
Mr. M but your guaranteed constant power. Solar and wind aren’t reliable because you have to wait for the sun and the wind. Besides solar farms are huge and destroy ecosystems. If your going to destroy the environment you might as well make the most of it.
@Mr. M you're not wrong but in the long run nuclear will have the least impact on the environment afaik. Renewables are great but require very specific conditions to be met and solar and wind farms have a massive impact on the local environment. I don't think we need to discuss flooding of nearby land when we build dams lol. Basically everything we do has an impact at this point 🤷♂️

Ah, the savannas of Finland.
Well, this was a depressing video to watch at the start of the day.
I guess I’m thinking about earth’s inevitable doom today.
Best way to look at it: no matter how bad we make it, even if we cause global temperature averages to soar by 10 degrees in 10 years, the earth will still be here and so will life. Humans, not so much. We'll go extinct and the earth will begin a transition back to normalcy. It's not the earth that's doomed, it's the people.
@@Aeturnalis Humans are all over the planet. It's pretty hard to make us go exinct. Massive culling of our numbers sure, but no extinction.
Jarle Skogly uhhh probably
During the Late Permian 240 million years ago during the great dying extinction, volcanic activity rose Earths temperature by 10°C and that wiped out 98% of life on Earth. Humans are warming the planet faster than that. We could reach 10°C warming by 2200. While we maybe good survive a 4°C warming at 10° it’s hard to see us survive unless technology improves greatly.
Aeturnalis while Earth itself is fine, humans, yes, will suffer, but also other life forms, for example Amphibious are dying out I’m pretty sure 800x faster than natural. Life will find a way. But barely. You can see this video on the 6th mass extinctions

The most important thing people must understand when it comes to climate change and seemingly small numbers like 2°C: The amount of energy it took to get there. Can you please make a video showing the scale of things we are talking about?
Like, if you take a small pot with 1L of water and put a thermometer and an immersion heater or somthing in it, powered that immersion heater with an ergometer and measured how long it would take to heat the water by 2°C.
Then you do the same thing with a bucket.
Then with a large bucket.
Then with a swimming pool. This would likely take anywhere from 20 to 500 people and immersion heaters to even register ( I have no idea how to calculate this properly :( ).
And then you ask the question "so how much energy do you think is needed to warm up the entire ocean by 2°C?" and make them understand that there now is the combined energy of 20-500 completely exhausted human beings in this water.
People need perspective to grasp these numbers. Show them actual maps of how much their hometowns will be flooded or anything they can grasp and understand.

Born and raised south of Vancouver in Bellingham, and Mt. Baker's snow pack hasn't been good for years. The ski seasons have already shortened and "good" days are rarer. When growing up there was a beautiful starfish population in Bellingham Bay, all gone (this was from some blight or disease that spread because of climate change). Forest fires have also become part of the summer season in much of the PNW now and we can expect summers with a week or more of smokey air. Heat waves are also beating records every year like Salem got to 117f/47c and Portland 114f/46c last summer. A wild thing people don't mention too often is how the pnw may become a haven for ecological refugees as climate change may not have as extreme of an impact here compared to some places that may experience more desertification and flooding. Whoo!
I biked the 316 km round trip Vancouver B.C. (not Bellingham) to Artist Point (my thumbnail) & back 23 times 2008-2015 and the ditch stream alongside SR542 on the final 18 km of climb where I always soaked my feet was all dried up in one of the later years. I really saw a drying up in summer from 2008 to 2015.

Rain period changed in my city. Noramlly, the city would get extreme rain in april, usually mid-april and at the end of the month. April was dry, farmers were sad as the river was dry. Then Bulgaria opened the dam to let some water out which tripled the water in river, not flooding this time thanks to a recently built canal and then rain fall that had to be in april happened in may. So, even local changes can be observed. Also winters are more extreme, by extreme i mean it is either no snow or -20 celsius and snow up to knee...
People don't get: It's the ENTIRE planet, by 2 degrees. Do you know how much energy it would take to heat the entire surface of the only world/home we have truely ever known? That's. A lot of energy.
on land its also a lot more than 2 degrees
Wouldn't increased rain and increased temperature be good for plants?? Just curious coming from a gardeners aspect
I think the fact that there will be some benefits is largely ignored. We can project and guess. But either way we're going to have to learn to live with warming or cooling climates.
Yes, people living in temperate climates seems to be going to benefit from that.
Yes and no. Global Warming can help grow plants in locations further north but also turns current farm land into deserts and caused extreme weather and droughts and floods causing farming to be impossible
The increased rain won't be everywhere. Some places will be drier - some much drier. Most of the rain that falls will happen during increasingly-extreme weather events. It won't help a gardener (or farmer) much to grow their plants when one (variable) day per year experiences 60 inches of downpour, and there's no precipitation at all for the next year.
Increased temperature helps many plants grow - but only to a point. Once it gets over 40C (104F), plants start dying out pretty quickly. The variability is what will kill you. Average temps may be up only 2C/3.8F, which might not matter to much of the temperate zone, but if you have occasional 45C/110F heatwaves of 3-4 days, the rest of the time won't matter a lot.

4:28 That's Grouse Mountain! I go skiing there.
It's gonna get real! Really quick!
Here we are at 1.5c
I feel like Hank should've mentioned it and possibly even linked his personal video (from Hank's Channel) on it but when people say +2C, they mean +2C by 2030. All the effects Hank lists are what would happen at +2C. But when we reach +2C by 2030 that's not the end of the warming, even if we stopped all human inputs to climate change the moment we hit +2C, it is still projected that we will be seeing +5C at ~2100.
This video shows how serious it is at +2C, imagine how serious it would be at +5C.
Btw, Do a video about muscle hank please :)))
I second this notion. LitoJonny got his own video, so why not?
I live in germany and the last few (3-5) years we had little to no snow. The last two years less than a week. Whereas in my childhood it was common for snow to last for months.
Such videos on climate change are so rare. You actually explain why and how this is important, without shitting on capitalism or industrialisation, or being hyperbolic about the results.
