Thank you for keeping your videos ad free

Thank you Dave, for this wonderful channel and please, keep the good work! Informed, trusted, sober and reasonable voices are needed in the coming turbulent times.

At least we can listen to a calm British voice tell us how screwed we are. Your American friends appreciate your work.

The governmental steps taken, or lack thereof, are quickly leading us towards large scale catastrophe and human suffering... I'm currently working on taking over our family farm in Norway, and have been shocked by the changers I've observed since my childhood(I'm turning 30 this year). The total lack of awareness within the farming community/governmental bodies, is truly frightening... The massive amounts of inputs and methods required for modern agriculture cause an enormous amounts of pollution, degrade topsoil, degrade waterways, reduce potential carbon sequestration, provide poorer and poorer quality fodder, and erase our much needed biodiversity. I truly hope more people will take the steps required to secure our future, changing is hard, not doing so is death... Thank you for your fact based videos, that help to inform the public, I hope it urges more people to also do their part!

6:47 The insurance issue is a significant point that I haven't seen much content on. If I lived in Florida then I could always sell my house and leave, or wait for a disaster to hit me, collect the insurance money, and leave. If insurance suddenly pulled out then my house price would plummet, because no one wants or is able to buy an uninsurable house. That basically means that I'm suddenly left with nothing. From my perspective, insurance pulling out is the disaster I need to prepare for.

The king crab season was cancelled this year because they seem to have disappeared. This goes hand in hand with the lack of nutrients that you pointed out here. Disturbing to say the least. Few thought the changes would be this dramatic this soon, and it is escalating.

Normally the warm Atlantic Sea water from the Gulf Stream would be exposed to cold air and in the process of ice formation, very cold dense saline water sinks to the ocean floor and moves south. That is the Thermal Haline Circulation (which we all know about). Now if the Arctic is melting creating a large cold fresh water low saline cap, it might make sense that the warm Atlantic water sinking process might be being interrupted, does not sink as much as it normally does, and increasingly flows (simply as a matter of the continuity equation) northward into the Arctic Basin. This would amplify the fresh water melting process in the Arctic. A slow down in the Gulf Stream Transport in my mind is similar to shutting down the flue over your roaring fireplace. The hot air back feeds into your house instead of up the chimney. Same for the Gulf Stream. Slow down the Gulf Stream and abnormally warm water piles up in the Subtropical Atlantic (back draft if you will). If the Gulf Stream is not cooling and sinking it finds a way into the lower level Atlantic salty water layer in the Arctic. The big question is, what does this do to the Atmospheric Westerly Jet Dynamics, and does that amplify occasions of Negative AO. In a weird feedback way, as you mentioned, due to the melted Arctic, we end up with lazy atmospheric long waves that drive abnormally cold air into lower latitudes that increase the severity of Extratropical Storms and dare say I winter snow storms across North America. In short, I think the melted Arctic will initiate a robust snow making machine across portions of North America. Warm moist air input from an overheated ocean colliding with abnormally cold air along an active westerly jet that is being forced much further south than normal due to a persistent negative AO pattern. We shall see. As a retired meteorologist, my gut is telling me more snow is on the way. Finally, with all the hot Atlantic water, it makes sense we might have more Tropical Cyclones... except... for that lazy long wave, which throws a monkey wrench into the pattern. You may have noticed the Atlantic High Pressure Ridge is remaining strong this year, and we have a fairly persistent albeit weak, upper level long wave pattern over the Eastern Seaboard of the U.S. So now we have a collision between statistical seasonal Hurricane forecasts based solely on ENSO and sea water temperatures, and a new player on the scene, called amplified long waves caused by an abnormally warm Arctic. Personally, I think everyone needs to step back and take another look at what is going on. PS, I am retired NWS /Hydrologic Modeler / Weather Forecaster. I also know you can tweak parameters to get a perfect match with past data, and end up with a model that is completely off in terms of undertanding what is physically going on. (Had a few printouts returned with lots of red ink... LOLs.) You basically can make a model do what ever your prediliction is. The trick is to understand what is going on. Thanks for your presentation. Really Great Graphics!

The water "conveyor belt" which travels from it's origin from the arctic down the coast of Africa and back up to India is the most important global temperature moderator. It depends on heavy saltwater at its start sinking and creating the driving force to carry it's temperature moderation half way around the world. If the saltwater is replaced by fresh water such as melting glsciers then it will cease to exist with a profound effect on moderation of the weather and all will be lost.

The old adage, "Plant a tree in whose shade we will not sit.' is a good metaphor perhaps... Unfortunately, we can't stop doing what we're doing long enough to rearrange the deck chairs on the Titanic...

I love the way you think the people we vote for, have most of the power when it comes to implementing environmental policy... The true power here lies with people we DIDN'T vote for... The Banks, the Oil companies, the conglomerate lobby groups, the investment groups such as Blackstone or Vanguard! THAT is why things have been slow to move... because there is no accountability for those with the power to REALLY make the changes needed.

We have a fantastic hot summer up here in Northern Norway, it's very warm and delightful indeed. Unfortunately the sea is dying, and the fish is gone. So the seagulls have to eat pigeons in order to survive. The reindeer's are starving as well and the perma frost in the ground at Svalbard is melting away. Everything is a mess, a sort of climate crisis so to speak. In the meantime we are all enjoying the burning midnightsun, working on the tanned skin cancer, while reading about all the temperature records, heatwaves and forest fires in Southern Europe. And don't forget all the methane gass from the tundra of Siberia. Have a nice summer! 😎🖤👍

Dave, I just wanted to take a minute to thank you so much for all the hard work you've done. Your videos are always top notch in providing valuable and accurate information, and the production quality is as well. I've been following you for a long time on the subject of Climate Change and I always think of your channel as my favorite place to turn for the actual truth in these monstrous times. For those of us who know just how serious this all is, you're a rock of stability and sanity for us to hold onto. I can't overstate how appreciated and important you have been.

Many thanks, the graphics and pictures help enormously to understand this complex theme !! Of course, the presentation is concise, clear, very up to date, interesting, objective, and positive !

Wow! I didn’t know it was getting this bad. Too bad the media don’t report these more often but they just have tiny snippets about it. This is sad and scary.

Your videos are of such a high quality. Respectful, done with humour but delivering a pretty terrifying message. I really wish more people were watching these.

Such a relief to have clear undramatic focused analysis. Thank you

Thank you, thank you. I've been trying to explain the seriousness of the climate change situation to my dad for 15 years. Sent him a link to one of your videos, and now, finally, he gets it and is telling me that I've underplayed it to him!!!

Today, in the Greek islands, catastrophic fires have put both lives and revenue from tourism at risk. What a shame it's not Downing Street in flames or the Whitehouse. Perhaps if the 1% were at risk instead of cruising in air conditioned Range Rovers, we'd have a bit of action.

What a remarkable channel, what a remarkable man, brilliantly compiling the research from all authorative bodies and delivering the (deeply disturbing) facts in such a calm and palliative way. I’m living on the hand to mouth breadline at the moment, but am itching to contribute financially to the channel. The channel should be broadcast on our publicly funded BBC.

What a great channel, and well eloquently said.

Changing the people who represent us has maybe never been more critical to the planet's long term outlook

Good call on the insurance companies. Over the past 15-20 years, I've found it's been a useful argumentitive tool against those who disdain 'so-called experts', a la Gove, to point out that the world's riskmeisters are in full, dispassionate agreement with those experts and their evidence.

Your channel is excellent, your videos serious and factual without being over dramatic scare mongering like so many on here!

Thanks for the video, brilliant as usual. Education is the key, knowledge is power. Keep up the great work!

I hope you realize they are taking g surface temperatures not air temperatures If we are being mislead I hope you would do the research to find out

As a famous species once said, "So long, and thanks for all the fish."

I'm grateful for the algorithm that brought me to this channel. Liked and subscribed 😊

"if the people who represents us don't change, we the people must change who represents us", don't know if I got it right, but it sounds really important. Thank you for sharing

Outstanding report with phenomenal clarity. Thank you.

You are on point: I am in Eastern Canada and we have had record rain. When there is no rain we have oppressive heat and humidity with humidex values close to 40c ... in the Great North. Everyone needs a wakeup call, this is happening. Over 9 iinches of rain in the first 16 days of July, like a Monsoon.

Very well done again. I am educating my kiddos with your videos as they enjoy how you articulate while making it very easy to understand. Thank you for all of your hard work with these very educational videos!

This was so so informative. What a great content creators you are. I’m a analytical chemist and I did my dissection on benthic and sea water column nutrients and nutrient measurements. Loved this video.

It’s easy to say we should just change who represents us. But when the “system” has been corrupted by the powerful political class, we are ALL subjects of dictatorships.

This guy knocks my socks off. I have no idea of his background, but it is obvious that he does his research thoroughly and diligently, not to mention a well-constructed and delivered narration. The graphics are way better than many a professional studio. And he does it without stupid annoying breaks for inane money-grabbing commercials.

Please do a video about insurance companies taking climate change into account

Excellent very clear and quite detailed explanation, thank you very much (just subscribed!) Popular science at its very best.

Great video, Dave, have we really got the leadership we deserve? I don't think I want to hear the answer to that.

why so many still deny that people are speeding this process up is beyond me. we need better education, everywhere.

Thank you for explaining this. Greed for short term profit for a very few people has put our species in danger. The planet will survive us, but will we survive the greed of the few ?

Hello from Greece, currently struck by forest-fires. I guess that, when we watched 'The Day After Tomorrow', we were all consoled and reassured that this was only a Hollywood disaster movie and climate change would take place really slowly (in the course of millennia). So our governments and we, the various peoples, kept on the same bad habits and now we realize in shock that climate change has sped up ... :-(

I don't know if anyone pointed this out yet but the Siberia / Alaska map is in reverse. Had me scratching my head for a while. (Edit) Never mind, I just realized that I've never see the bearing straight from the perspective of the Arctic side looking south.

It is so frustrating and infuriating and scary that our 'leaders' are failing us, that too many of the general public are blase or outright deniers, or too poor and focus on survival today

While I find this video simply excellent and informative and undeniable, what is to be done? There is a lot of talk about pressuring those who have the power in the comments etc but the presenter himself states: "...to late to put the genie back in the bottle." So ultimately what is the ask here? Furthermore, the immediate conclusion that we can somehow do something about it seems extremely arrogant. We are but guests on this planet. So really the only question remaining is how we live together and organise ourselves. We should obviously do as much as we can for any small impact that might have but we shouldn't fool ourselves into thinking we can fix something we don't entirely comprehend. We should absolutely continue to study the phenomena and attempt to do what we can but realise we do so with probably very little chance of reversing anything, purely for figuring out what our future holds and how to manage that.

"Arctic heat is coming our way" is not a phrase I ever thought I'd read.

I don't always like what you say but I appreciate your contributions to the conversation and my thoughts

IMO, the real problem is NOT the change in weather. Floods, heat waves, droughts, we can deal with. We can cope. BUT --- there are TWO things we cannot cope with. 1. Sea level rise -- it is NOT a flood that recedes. It is land permanently submerged. With oceans rising at least 70 FEET (to match Pliocene levels) all of Florida is gone. So is Louisiana. Houston - gone. Shanghai and all the land 100 miles inland - gone. Bangladesh - gone. Nile Delta - gone DelMarVa peninsula - gone. Newark NJ, and Brooklyn NY - gone Holland - gone London - 1/2 gone Venice - gone Calcutta - gone Manila -gone Etc. etc. Get my point? How do cope with that?? 2. High wet bulb temperatures -- making life impossible without A/C When that happens for extended periods of time, people will die. Already high wet bulb tempertures have happened in India for a day or two. What happens when they extend for 2 weeks or a month?? Tens of millions or more will die. The latest heat wave in the US saw excessive wet bulb temps in CA and AZ. Not everyone has AC. A blackout could be deadly, not just an inconvenience. Is this serious?? Extremely. Can we stop it? I don't think so. BUT - we can slow it down. And we might be able to stop it from getting too extreme.

Ps. Great video and very intelligent comments below. People are really thinking today.And many lost everything already. Its hitting faster then expected.

Here in New Jersey, and adjacent New York and Pennsylvania, we’ve had flooding which has been fatal. While in Vermont, there’s been flooding that surpassed the flooding done by Hurricane Irene in 2011. Thanks for some straight reporting on a runaway existential crisis.

(8:15) "... the Arctic is a long way away, isn't it? ... unless you live in Canada or ..." Surely this is a bit of an odd comment? I live in Canada, not far from Ottawa, which sits at 45.4°N, compared with London at 51.5°N. Meaning: London is some 420 miles closer to the Arctic than Canada's Capital city, and some 640 miles closer than Toronto (@ 43.7°N.) In fact the 'entirety' of the British Isles is closer to the Arctic than almost all of Canada's major urban centres. I suspect though, that you were actually hinting at temperatures, rather than latitudes. Ottawa is after all, the World's coldest capital city. Dare I say however, that the UK is likely far more vulnerable to a climate driven shift in ocean currents, than for example, Canada. You are a lot closer than you might think.

So informative, as always. Thank you!

in australia the winter has been weird it been acting weird sometimes its warm but then its been extremely cold sometimes it feels like spring then like winter again

In the area I live, (Cal/Or. boarder) I have witnessed several types of flora and fauna move in from the warmer southern region. Robin,Starling,Asian Dove / different types of Thistle, Sosala (tumbleWeed)

So much for the U.S. House rep from Oklahoma, USA, who brought snowballs from a recent winter storm to the House to prove that the climate is not warming! Trouble is, that person seems to represent the majority of people--everywhere. Humans are amazing, but not quite intelligent enough to survive.

Tipping point? We have long past it. Consider -- 2.5 MILLION years ago was the Pliocene. A bit warmer. Oceans were 70 FEET deeper, at least. Atmospheric CO2 was 390ppm. Today, CO2 is at 420ppm -- much higher, and rising at 2.5ppm per year. SO - even if we stopped CO2 rise completely -- we would still be on track to duplicate the Pliocene --- only warmer. So you see, we have already past a major point. The seas will rise at least 70 FEET to match the Pliocene, or even go deeper.

Thanks very much for your videos Dave. They're all so good, but you clearly articulated why I became obsessed with the arctic about 10 years ago. My one quibble, and maybe something you could do a video on, is the use of RCP-8.5 by the authors of the paper. My understanding is RCP-8.5 is includes almost no emissions mitigation and implausibly increasing amounts of burning of coal for decades to come: it's basically 'burn all the coal you can'. RCP-8.5 is definitely the worst case scenario, but it is also basically an impossible scenario, it is worse than status quo/business as usual. As we are clearly in the middle of an energy system revolution with accelerating renewables and EVs, (along with a host of other emissions lowering tech you've been covering) we will never hit RCP-8.5. I believe RMI recently put out a paper saying that emissions will soon start coming down. It would've been nice if the authors of this paper also did a version of RCP-4.5.

Just ask your friends and neighbors if they are willing to turn off their heating , air conditioning , stop driving their cars and other things that might use energy Pretty sure none of them can survive without those basic things

Awesome Video. You give me more confidence in humanity.

Great video. Great pics ending If the people representing us will not change then it's up to us to change those representing us

Only yesterday, I watched Black Gold. According to the information in it, Exon was doing sea and air research into temperature and carbon levels. It seems this research is a kind of an expansion of that start they pulled funding from in the 70s. They well knew climate was affected by fossil fuel use.

Ty for putting this together. Let's all think long and hard about what the children's children will be inheriting.

Have a look at the Sea Surface Temperature Anomalies around Greenland. All far below normal, this is due to the immense amount of glacial runoff water (which spills into the ocean at just a few degrees C), which is happening at a higher than normal rate.

Given that the last 10-15 years has resulted in swings to right in politics, which has made countries more insular politically, it has frustrated the living daylights out of me that the very thing we don't need for combatting HICC is that attitude.

Earth nullschool isn't from Google. It was created by Cameron Beccario, and is a wonderful tool indeed.

With all the discussion about where we are and where we are going, a large amount of discussion is missed. First, and probably the most important behavior to understand, is that organisms adapt to change and that they don't proactively adapt. The term adapt by definition is reactive. That has been the mechanism of all living things, including humans, on this planet throughout the Earth's history. Our best hope for the future is to strongly prepare for the coming changes. Use all the resources at our disposal to invent, design, produce items and techniques that will ensure our survival and allow us to thrive in the coming environment. Stop wasting time and resources on closing the barn door after climate change has left the barn.

As always incredible work. Thanks for the video

It doesn't look good, does it? Thanks for this good summary again.

Outstanding videos Dave, first time caller long time listener. I’l typically wired on the positive and optimistic side for much of what life throws at me, but has anyone else pretty much thrown in the towel and let despair take over? The WW2-style global scope mobilization needed to keep this car from going off a cliff doesn’t appear to have any chance of happening. Nuclear is the most bang-for-buck tool in our arsenal in my opinion, but people just picture more Chernobyls and Fukushimas happening. Graphene-this, biofuel-that, any positive development I hear about can’t or won’t be scaled in time to make a difference. I feel that we’re totally screwed, nearly without hope, and on a ride to a nightmarish hellscape that we’ve been buying tickets for since the late 1800’s

"Put a value on nature that goes beyond just money"

Completely agree with the wrap-up. Time to change those who represent us.

6:35 I really wish scientists would look at reasonable averages for once instead of looking at extremes that will serve no purpose to provide a forecast and will only cause polarization among readers. Yes it may be less "hey look at this!" attention grabbing but also keep things real for everyone.

It's hard to believe that people fly to vacation spots. buy new cars, replace their phones for some newer model, think that the newest fashion is a 'must-have,' and eat meat at every meal. Humans seem to be truly suicidal. PBS is sill sponsored by cruise-ship companies. No one seems to 'get it.'

I find it astounding that some politicians continue to deny our climate is changing.

Thanks for another clear, concise, and well-formed video. The way in which we humans choose to continue to run our lives on this earth is indeed paramount. One of my favourite books is 'Less Is More' by Jason Hickel. I highly recommend it. It discusses the way the global north is indebted to the global south as mentioned by attenborough in this video, but most importantly it speaks to the idea of economic degrowth as our best option for averting the worst of the climate crisis. This kind of systematic change is about the only thing I can see potentially doing enough and probably won't come about under most of the current political conditions around the world, unless groups like extinction rebellion and just stop oil become more successful with their civil disobedience campaigns (just as the likes of the suffragettes, ghandi, and american civil rights activists were successful).

"If the people representing us will not change, it is up to us to change the people representing us." Excellent point... but we didnt choose our last two PM's and the current one caused a financial mess as chancellor, then got the top slot, a little WEF stooge... we are doomed.

The oceans will boil, the skies will burn, the mountains will crumble, and mankind will whither.

Here in AZ i been noticing a shift in the weather that became very noticeable since 2020. Not sure whats going on, i just know we should probably get used to whatever changes are coming our way

This reminds me of Ronald Reagan's statement about the nine most dangerous words in the English language, "I'm from the government and I'm here to help".

Incredible video! Thanks. I would add that the challenge is global and it's our relation with nature, society and the economy that needs to be reinvented. Even if we were able to find an infinite decarbonized source of energy, without a fondamental human behavior change, we would be using it to accelerate our pressure on the environment even more by converting minerals and ressources into waste, dirt and pollution.

Hi Dave. Canadian here, and although, as you mentioned, I would be concerned with the arctic, I am more currently troubled by the explosion of forest wildfires. 67 new fires in the last week. 2/3 started by lightning. So the forests are unusually dry, obviously, but we still have winter, and thus snow, and spring, and thus melting snow. Lightning of course only comes with thunderstorms, which means at least some amount of rain. Burning question ( pun intended), is this a result of climate change and thus more likely to become the norm? ps. I think this is worthy of a full video. 😁 Thank you.

Excellent vid again. It's heartening to hear you becoming a bit more overtly political (if our leaders won't change we need to change our leaders) but also disheartening that it has come to that point for you. We're in a crisis. Thanks again for your valuable insights.

EVERYTHING is connected - that's the BIG takeaway for me Dave...everything except economics and modern accounting. I'm a newbie fan btw - so I'm busy catching up! Thanks for your epic endeavour!

I remember visiting China after my son graduated from college as a computer programer. It was during the bird Flu and visitors and everyone was subject to a laser temp check on their forehead. I will never forget the thick smog and it was so thick you could not see pass a 1/2 mile. After the trip o 3 months, I developed major bronchia and required medicine to restore my lungs which was full of fluids. Yes it was horrible and the other thing was everyone was smoking cigarette. This was really bad

You have a remarkably calm demeanor while describing how screwed we are. I feel like Sir Attenborough, in that I'm about to have a stroke

Terrific presentation, thank you.

The Arctic dipole anomaly is a pressure pattern characterized by high pressure on the arctic regions of North America. This pattern sometimes replaces the Arctic oscillation and the North Atlantic oscillation. It was observed for the first time in the first decade of 2000s and is perhaps linked to recent natural climate change. The Arctic dipole lets more southern winds into the Arctic Ocean resulting in more ice melting. The summer 2007 event played an important role in the record low sea ice extent which was recorded in September. The Arctic dipole has also been linked to changes in arctic circulation patterns that cause drier winters in Northern Europe, but much wetter winters in Southern Europe and colder winters in East Asia, Europe and the eastern half of North America. In the 1990s and early 2000s, many studies of Arctic sea ice export focused on the Arctic and North Atlantic oscillations as the primary drivers of export. The Arctic dipole anomaly has two poles of opposite sign: one over the Canadian Arctic Archipelago and northern Greenland, the other over the Kara and Laptev seas.[11] This dipole structure leads to a pressure gradient with a zero isopleth oriented from the Bering Strait, across the Arctic to the Greenland and Barents seas. As a result, anomalous winds are generally directed parallel to the zero isopleth either towards the Greenland and Barents seas (positive Arctic dipole anomaly) or toward the Bering Strait (negative Arctic dipole anomaly). However, the Arctic oscillation cannot be ignored when considering sea ice export from the Arctic. By itself, circulation associated with a positive phase Arctic Oscillation results in an increase in sea ice export, while the negative phase of the Arctic oscillation is associated with reduced Arctic sea ice export. Once again how much is natural and how much is man made? I live 700 miles from polar bear capital of the world but can't go hunt one with a bow. Save the polar bears. I wanna go hunt one. I do like the electric motorcycles and boats. Why don't electric vehicles come with solar panels.

Revolution, fight for climate! I'm a chick forest technician from Montreal who left my career over disgust of how things work in Québec, unbelivable! Ya too bad thinkings not what they want to do!

Being able to go Swimming at a Scottish Sea side without the high risk of Hypothermia will be nice.... Once the warm water Apex Predators have died off I might dip a toe in.😂

It is wonderful in seeing just how alive the world is over these billions of years. There has not been anything like this beautiful earth planet found.

Both Dave and Sir David have got it right. Carry on sounding the alarm!

Dear David, thank you for your last sentence, the change is on the way

Little comment for the algo, thank you for spreading this message.

Unfortunately there is no other incentive to produce anything if not for money and growing capital and under this condition we will never face the challenge of climate change properly.

10:50 Love Sir David Attenborough. He has started to narrate Warhammer 40k lore!

And after it all has been said and done, there's a lot more said than done.

It is bloody freezing in Normandy, send me some Arctic heat baby!!!

And then there's all the scientific community saying that this is garbage. Peer reviewed means pal reviewed....

This is really sad. Somehow we have neglected politics and corruption for too long. Democracy licks our self-centered behinds every few years and every time we go for the same cheap one. We do not choose between politicians or politics, but between companies and industries. And not even between them, because they lobby and finance all parties and parties compete for their money. One or two less corrupt or caring people in some party means nothing. Actually they are just there to blur our perception.

I live in Colorado, USA along the front range next to the Great Plains. We are actually wet but hot. The Plains which is our breadbasket is experiencing the same. Recently there was a tornado on Pike's Peak, at about 8500 ft elevation, which is highly unusual. I originally lived in Michigan, surrounded by the Great Lakes. They are experiencing heat and drought. The climate is definitely changing. Lucky for us in the Western US it has been a slow forest fire season. Unfortunately it isn't the same for Canada, and their fires have made our air quality dangerous many times

Sverdrup for a Dutch or German is very apt word for an enormous mass of flowing water. While drup is our version of English drip, sver sounds just like our word for heavy. Heavy Drip, that be just what a Sverdrup is :)

First 4 mins. There you have it. Pacific Ocean is hot hot hot. 3 full ongoing meltdowns. North Atlantic now also hot. Both Oceans dying fast. All life.
