What Could THOUSANDS of Mysterious Whales Tell Us About Our Weather? 

Hi, I live in the Sierra Nevada in Andalucia. There has been a drought here for 10 years, every year is worse. hundreds of olive and almond trees are dying right next to my land.Our snow fed irrigation channels are rationed in winter and dry from June until November. The oldest people have never seen such a drought. hard times

Well, when animals of all species run from a forest fire, they stand shoulder to shoulder...Fact is the fire is not that far away when you see that. Tell people you love them and build up others before it's too late. Great health to all.

Girl, you are on point with keeping track of events. Can you apply your experience to imaginably create a visual prediction of what is to come next?

Southwest Michigan slightly inland. In brief - in a single week we've gone from no snow to enough snow to close down stores and offices or freezing rain tearing down power lines to once again no snow and then repeat for three of these cycles in the past four weeks. It was warm enough buds on fruit trees have come up over a month early. That is freaking crazy. I wonder will we have enough trees left after the last two cycles to withstand a harsh summer in what's left of our local city forests. Simple presentations of the facts is Not motivating. There is nothing I can emotionally hook onto. If you were to say air turbulence could get so bad all flights would be cancelled for several months of the year, or something like that, you might get enough concern out of people they might pressure lawmakers.

I'm 58 years old and live in Germany. I am seeing profound changes: Winters are getting ever milder, spring comes earlier, summers are getting hotter and the most troubling of all: spring has become silent. In my youth, you got woken up by birdsong and could bees buzzing in each flowering plant. That is no more. I'm deeply concerned.

I've been seeing significant changes in weather and climate where I live for 35 years.

I live on the coastline in QLD ,Australia, It’s been a windy year.

I recently watched a 3-D movie presentation at our local, natural history Museum about the dinosaurs in the Arctic, and how it used to be basically a rainforest, have to wonder if the Earth is just running on earths course and we are watching it play out

I love how we think we can keep the planet static in terms of climate. The definition of climate is weather over time. All on a planet that demonstrably cycles between long periods of intense cold (glacial) and shorter periods of milder temperature (interglacial). The cold is coming, and probably sooner as a result of any heating if you're into all that; it's hubris to think we can do anything about it.

It is sad this is happening, So many people on this earth between those wealthy enough, Politicians and even a lot of everyday folks. But the biggest reason we can not change is greed. There would be a lot of things I would implement if I had the means to. I do appreciate all those who can and are fighting to make changes possible.

As a whale researcher, I would like to complement you on this excellent report. Clear, concise and well-presented. Keep up the great work!

Word. 2 years ago, we made a video about orcas / killer whales. We followed them into parts of the Arctic where they've never been seen before. The consequences were mind-blowing!

Here in southern British Columbia, on the Salish Sea, we have seen an uptick of Humpbacks, with this last year 400 being identified, the most recorded. Researchers feel this increase cannot be accounted for by population growth alone and indicates that the population has shifted here from elsewhere. Another indication, perhaps, of impacts from the changing climate.

I live in Ottawa, Canada and when i was a teen, we used to have weeks in the winter of temperatures under -30C. Now, we get 1 or 2 days a year like that. It is very noticeable.

Here in South East Australia, (the eastern end of Bass Strait) Humpback whales were prevalent and a tourist draw card. I have not seen a whale in the last 2 years.

I watch a lot of climate news and I must admit that you have carved out a distinctive niche and are doing an excellent job and getting better with each video. Thank you for your efforts. Oh yeah, I have no idea how to respond if you are NOT worried about these changes.

California has been experiencing crazy weather. Extreme drought. In the last two months California has been getting one of the heaviest winters ever. Tahoe may break it’s snowfall record. One of my biggest pet peeve is the people that say this: “ you are getting a lot of snow, stop with the global warming thing. It’s clearly false” They don’t understand that global warming effect winter too.

My concerns are that the tipping point can happen much faster than we think. I remember reading about the last ice age and that it may have happened much faster than previously thought because there were blades of grass trapped and preserved in glaciers. Not exactly scientific proof but certainly something to consider. Change happens slowly, until it doesn’t.

I live in Denmark and the biggest year round change I’ve noticed is it is significantly more windy.. it feels like it’s always windy and way more storms all year round. In the winter we sadly don’t really get snow anymore, maybe a few days a year, but it rarely stays to the next day.

The biggest thing I've noticed here in Zone 6b Ohio is more frequent and more extreme weather shifts. For example, we had a sudden extreme drop in temperature and an actual blizzard during the week of Christmas this year. On Dec 23 we saw temperatures hit -8 deg F with windchills in the -30's. This is colder than I ever remember it being here. Then, within a week's time, temperatures shifted and we had an unseasonably warm spell where it was over 65 deg F and felt like spring! That kind of shifting between unseasonably cold and unseasonably warm weather has become very frequent. And with nearly every extreme shift comes storms and damaging winds.

Canadian winters are far more mild, and the snow isn't nearly as deep as it once was. That means less moisture, and more top-soil erosion for farmers. The rich black soil that used to be feet deep is turning brown, and only a few inches deep. I'm concerned about global food supplies of the future.

I moved away from Utah because the forests in the mountains, particularly in the Uintas, have been completely devastated by pine beetles, a native species that has grown out of control because of the warming climate. They normally were kept below a certain elevation by long, cold winters. But they aren't impeded by the cold anymore, and an entire ecosystem is collapsing. Gorgeous, pristine mountain forests in 2009, by 2014 all grey, 90% dead trees. I couldn't handle it anymore, it was just too depressing. So I moved somewhere greener.

I've noticed winters getting milder my whole life. Being someone who grew up in the countryside I notice these things, but I always wondered if I was remembering it wrong, but then my Mum gave me one of her old winemaking books which said things like "sloes are best picked after the first frost, usually around the end of September" most years now the first frost is in November or even December.

This is sad and creepy. What I don’t understand is how people are comfortable denying and ignoring what we can all plainly see.

In my home state of Utah there has been what they've called a "thousand year drought" that is likely not going to get better unless we get above average precipitation for years upon years. Meanwhile, where I live in Panama, the climate in the mountains is noticeably warmer within the last generation and the rainy/dry seasons are not as reliable as they used to be.

This terrifies me. I am struggling to accept that we will no longer be able to predict the weather, that major weather events like tornadoes and hurricanes will happen in new places. I live in California, where we’ve been enduring severe drought for years. But this winter and spring has seen heavy, regular rainfall and the snowpack in the mountains has broken records. I’m enjoying the green and hoping for a reprieve from the drought, but I also know that long-term this weird weather will probably have major consequences. I fear that the world I’ve brought my children into is becoming more and more dangerous for them, and I feel powerless to stop it.

I grew up in Germany. When I was a kid in the mid-90s, we had at least 3 years with snow 20+cm deep, sometimes even reaching like 50cm. In the last 15 years, I haven't even seen 5cm snow depth and in the last 10 I don't think it even got up to 1cm. On the rare occasion it still snows these days, the snow *always* melts the same day.

Australia. Its getting hotter more often. Fires are on a scale that is just unimaginable and they burn so hot, intense fast moving and explosive (Our plants are mostly Myrtaceae, its full of turpin oils). Then it rains and rains and rains flooding constantly multiple times. We have lots of destructive bugs growing in number. They eat the gum leaves of particular eucalyptus species. Those rough barked trees are dying off. Others are dropping off to fungal infections. A lot of native species can't tolerate saturation so they are dying off too. Rain forests are thinning out at the ground level. There are fewer species of community plants that cover the soils exposing them to drying out. In many locations there are damp gullies where tree ferns grew for thousands of years. They are gone now. The floods have washed them and the trees away leaving VW sized rocks in their place. The weather is getting stronger in its extremes. When its dry its really dry. When its hot it gets stupidly hot 48c once but weeks of 38c. The winds are getting stronger, dangerous speeds. They are blowing trees over that stood for 150 years. And the rain, its like tropical monsoon rain that all comes at once. Then a few weeks pass and it does it again.

Both the arctic and Antarctic act as our natural air conditioners keeping our planet relatively stable, but they're not working as efficiently as before.

Living outside of Chicago we have significantly milder winters than we used to, yet far more volatile weather events, especially in the spring and summer. The pool level in Lake Michigan also tells quite the tale if you look back at historical numbers. Yeah, it's bad.

As a former AK. fisherman in several fisheries I’ve been all over maritime N Pacific and Bering Seas ..and a migratory bird(if you’ll allow) AK-HI-Baja Sur,Mexico ..I’ve seen much change..the absurd jet streams these days..the ‘spraying’ of the skies I’ve seen everywhere ..bird die offs ..its the arctic which leads and I along with many others who are scared for our future(s) ..

I live in Southern Ontario, Canada and so glad to see this! Our winters are not the same from 55 years ago and either are our summers. We have extreme weather patterns and working outside in career, I have seen and felt the changes. I remember feeling like Dorothy in Kansas in the late 1990's with a dust storm whipping up all around me. How do we get the politicians to accept that we can not wait any long that the power of capitalism is going to kill us?

Brace yourself... summer is coming

I think there was only a few -40 days this winter, and usually we get at least three weeks of it. This winter was so mild.

Living in Oklahoma I am very much concerned about the changing climate and unpredictable weather anomalies. 318 mph winds recorded 30 minutes from my house in Moore Oklahoma May 3rd 1999. My fear is that record will be broken and quite possibly in Oklahoma and sooner rather than later.

We recently moved to Maine, interior - not coastal, and folks around here have been saying it has been a really mild winter. They were talking about how much snow this area used to get. We heard that winters haven't been really bad in about a decade and this year was the most mild.

Granted I drive through countryside now, when I lived in the city before. But in all my years, I don’t remember seeing bluebonnets in full bloom in February down here in central Texas. That kinda tripped me out. Not used to seeing them until late March and April.

Don't forget that the crabs will be able to move into antartic and artic waters and impact the underwater ecosystem as well.

The hole we punched in the ozone layer definitely didn't help. I'd like to see a full episode on that topic.

I live in London but did half my education in Florida. We’re getting what I can only describe as hurricanes. Both the tail ends of actual hurricanes that are downgraded to tropical storms and last long enough to make it all the way across the Atlantic, and severe low pressure storms that form N of the tropics with high winds that we’ve never seen before like this. It’s horrifying bc the island I lived on for middle & high school just got completely covered by water and shut off from land/water/power/food 6 months ago. Truly the nightmare scenario we always said would “never happen”. It’s already happening to even the some of the most privileged people in the global north, let alone everyone else.

Bark beetles have killed half the trees in our once-lush forests here in New Mexico. In Albuquerque, snow used to cover our Sandia Mountains from October until April. We used to get real snowstorms in Albuquerque, but we haven't had a normal winter in over a decade now. Very worrying, because life on Earth is a very delicate balance, and we have already upset it in ways that threaten our future here, and that of countless species.

Understanding this and the ongoing effects is more important than being “worried”… The optimist in me is also leads me to observe human behavior, which is usually a push/pull . “Apocalyptic” is the word our youth (20+ yo) use the most. Overall: We are a dense cruel mindless generation leaving such a disaster behind.

Yes I think we're all seeing changes....winter has been delayed by a little each year for the last 3 years

I’ve noticed that trees around me look dead and that fall happens oddly now. Likely because of prolonged summers. Our winters had been getting more warm until this year. I’m in Central California.

In Southern Ohio Spring is at least four weeks early and that just must be disorienting for small to tiny living things. Somehow I think it is connected to troubling warmth in the arctic upper air masses. But he local weather people and news casters just make jokes. I feel very anxious.

I live in Colorado at over 9,000 elevation. In the last 15 years, I've seen lower elevation plants migrating into my yard----some that were never found above 7500 feet. That's a 100 foot elevation increase per year! That's not gradual, that's a sprint.

I live here in Philippines🇵🇭🇵🇭. . Wee are in the months supposed to be summer and dry season but still raining and sometimes always cloudy .. big changes happening here also

I grew up in northern Virginia. We used to go to my grandparents house that had a small lake that froze over in the winter, and we used to skate on it all the time. Nowadays, the lake no longer freezes over, and we are told that even if it does freeze, the ice is never thick enough to skate on. This past winter was very abnormal as well. Growing up, the temp in the winter never got above 60-70 and sometimes went into the negatives. We have had several heat waves this year alone with one or two even reaching into the mid 80s, and it rarely gets into the single digits or negative anymore. When I was a kid, we would usually get several small snowfalls and at least 1-2 heavy snowfalls a year mostly in January and February, sometimes even getting a couple of feet of snow. It has snowed lightly once or twice this year and melted quickly. This has been the case for the past couple of years.

It's going to be drastic when the high salinity layer reaches the surface.

I live in southern France. When I was 10 there was abudant snowfalls starting from late november until March. Im 15 now and trees already started to bloom during late January ( only a few but still.. ) Right now most of them are getting flowers.

I've been noticing changes here in the midwest for years. The summers have been scorching hot!! Some people think an early spring and a warm fall is wonderful, but it's so not wonderful for our precious and very vulnerable eco systems. Why does something bad have to happen before people start to care? I've read articles and seen posts on social media that scientists are so worried about our planet they are debating worse-case-scenario solutions to implement to reduce mass casualties from the heat. Some are discussing ways of blocking out the sun, like spraying aerosols into the stratosphere to reflect sunlight back into space. We have a major ongoing cleanup of the 5 gyres of floating garbage underway. I wish there was a way to turn that floating debris into white floating platforms (maybe the size of large swimming pools) that could be connected and anchored in places like the Beaufort Sea, that could serve as habitat for the wildlife in the arctic, as well as help reflect the sun to help cool the area. If we can build zoos, theme parks, sky scrapers, and cruise ships, I feel like this idea isn't completely ridiculous.

It seems to be a similar situation here in the SW US. When I was a child, I remember days of brutal cold weather. Now it’s seemingly rare for us to get into even barely freezing temperatures. Even my childhood was different from my mother’s- she remembered much more snow when she was a kid than even when I was a kid. Naturally, there’s less rain and snow. I’m a bit heat intolerant due to medical issues so I absolutely hate it. I’m not sure where to move to.

In the Southeast we hear about the northern polar regions quite often, usually with "polar vortex" getting thrown around a lot. Winter this year was cold, but dry - no ice, but plenty of folks struggling with frozen/broken pipes (normally it doesn't GET that cold, this far south). To an extent this is "easy to fix" for the humans - get insulation on your pipes, do the things folks farther north do to "winterize," and so on. But that doesn't fix things like the knock-on effects for wild creatures such as forcing some birds to go even farther south in winter, or certain native plants struggling to thrive in these unusual conditions; only this past year (after at least five years worth of "hey look, really cold air is coming from the Arctic, huh, interesting") are folks here beginning to feel that kind of impact. Planting season comes early here - really early; Feb 14 has been "the day to plant your potatoes and onions" for as long as my mother-in-law could remember, and for as long as her dad (a sharecropper) could remember too. THIS year, those early crops could have been put out in the very first week of February...seems like a good thing, no? A longer growing season can mean more food, right? Except that the OTHER change, with winter being fiercer-yet-shorter, is that between now (early March) and the end of April - we could get actual SNOW if there's a cold snap at the same time that we've got lots of humidity. It's happened before, but was "just a freak weather pattern" in 1994. Now it's becoming more and more of a significant possibility, to the point that some local agricultural groups are warning gardeners and farmers alike to keep an eye on the sky. The first weeks after planting is the most vulnerable time for crops, while their shoots are still getting established - especially for long-growing things like potatoes. So - if all these changes in the Arctic are already happening so fast, AND they're part of what's driving the steady changes in weather in my area - which really sounds like exactly the situation - then the less sea ice we get each year up there, is worse news for folks down here. And we're half a world away from Greenland. And even worse, there are still people who are so confused about climate change that they're trying to claim that folks in the southeast US "can't affect" the climate in the North Atlantic. Those folks just don't get how interconnected our planet really is, whether because they aren't getting the right facts or because they're blinkering themselves in an effort to feel better. The conversation has to keep going, and we gotta find more ways to get the point across without ALSO making people so terrified and overwhelmed that they just shut it all out and pretend it isn't happening. And for what it's worth I think this channel specifically is REALLY helping move the conversation in that direction, towards constructive worry instead of paralyzing panic. So thank you all, the whole team, for all that you do!

We've been getting warmer winters and cooler early springs in the northeast USA.

I live in New England, in the state of Rhode Island. Last year the allergy season lasted well into August (when the annual misery formerly only lasted until mid-July) and there were yellow puddles of pollen everywhere, which I have never seen up this far north - I hear that sort of thing is more common in the warmer & humid southern states. I hope this is not an indication of what it is going to be like every year from now on and I will just have to endure it.

I've lived in England almost 19 years. My first decade and a bit here, the yearly weather patterns only had about a 30 degree Fahrenheit difference between peak summer (~70f) and winter (~40f) temps, with maybe a handful of days outside that range and rain year round. In the last 5 years of so, we've had weeks or months of 80-95f in summer and drought and weeks or months around or below freezing with more snowfall (it's been snowing all day today, actually). I've seen more snow in the last 3 or 4 years than I had in all the previous years combined.

Wow! Very interesting and very scary! I hope we will learn to take better care of our planet. Thank you for another eye opener Maiya!

Whales and dolphins. By the way, I have difficulty communicating because I had a stroke in Broca’s area, the part of the brain that controls speech. 2/8/2021 but I lived again. (My wife helped me compose this.)

Hi. I live in Northern Ohio, just under Lake Erie. I am very familiar with the outdoors, I am part Mohawk and consider the woods as my home. I can feel this change taking place!!!! I can smell it, the winds and atmospheric pressure have drastically changed. It will be interesting to see how humans adapt. Another change that I wonder about is; How will humans deal with a mile thick glacier of ice scrapping large cities into the ocean? That will be a sight!!! Eventually it will happen.

Extreme drought conditions in California, followed by a record setting wet season that disrupted major highways and damaged entire swathes of the riverside. We had a blizzard warning. In Southern California.

I live in Michigan. Two years ago, Christmas Day and Boxing Day were in the 60s (Fahrenheit) and I was outside mulching leaves. Very unusual. Dandelions have also popped up in winter over the past five years or so.

One thing that always gets me as we get more and more detailed data and packaged-for-the-public graphics, is the unfortunate feeling that those who can make a difference are actively not listening. Almost every average person is very climate aware and climate concerned, but the people with the majority of power, money, and resources to make the necessary change don't seem convinced. I am currently sure all they will do is build themselves and their families and friends and necessary employees climate controlled bubbles to live in. They will make bunkers. They do not care to preserve the earth we live on, because that means sacrificing private jets and massive property and the ability to buy literally anything and control global politics. We need to make all of our cases directed at the ultra wealthy imo. There cannot be an upper class if the entire lower and middle classes are wiped out. I want to ask them "who will work for you if everyone is dead? Who is there to even feel superior to?" and I honestly fear the answer will be AI. I don't think playing to their morals will work, and so I truly don't have an answer. I just am not convinced that anything besides directed pleas and arguments to those with the actual resources will make the change we need in time. Bill Gates has said he will give away basically all his money when he dies, but he's giving it to the foundation his own family created. It is not controlled by the people. It is controlled by other wealthy people and their opinions on what is "best" for the rest of us. They are only required to donate 5% of their entire assets each year, and there are wide criticisms of how they do that and what policies they enforce. The continue to move to privatize education, and believe test-score based funding is the way to improve schools--an absolutely insane idea. Why should schools that are doing worse receive less??? They need MORE to improve, not less lmao. The foundation also invests in whatever they want to get "maximum returns on their investments" and have no concern for what those companies do. They have invested millions of dollars into GEO, the second largest private prison corporation in the US. A huge part of what that corporation does is incarcerate and detain the migrant peoples at our borders. People have begged them to stop investing in GEO, and they say no, we want more money. It makes no sense. This is just some of the many criticisms of the foundation's work that are easy to find online, but to me highlight the issue: they are not beholden to the people, at all. So, that is the one "good" billionaire. The one people think of as an example of the wealthy doing their part. I could not disagree more, and anything less than full democratic control by the people of resources will never accomplish the change we need to maintain our environment.

As a former Navy submariner, I can tell you from first hand experience that 'big rolling waves' or sea swells can easily disrupt stratified waters. A single storm can disrupt existing stratification for weeks to months. Arctic open water year around could happen much sooner than predicted. This tipping point could domino into permafrost collapse... and then...

I miss getting good 18-24" of snow to go cross country skiing or kids to play in, here in South-Central Wisconsin. The last 10 years, there is usually 6" or less on the ground in the winter. "The times they are a-changing".

Yes I have seen changes with King tides. I have lived in the Humboldt Bay area for 40 years. In the last two years flood events because of sea level rise

We saw huge flocks of migratory birds around our farm in Central Kansas. We always have migratory birds, but not in the numbers we saw this year. More snow geese than Canadian geese and huge flocks of ducks wich we never see more than a couple. And there were other birds in larger numbers. 17 years here on our farm and this was noticably different. And of course the weather. Very up and down. We noticed our normal winter lows are dropping over the last few years as well. I spend a lot of time outside. To me things are changing.

Honestly, we are technically still in an ice age, this seems like the true end of the current ice age. The animals I think know what is happening. I think the sea animals will adapt much faster than we will. Lizards have already begun to change and adapt to stronger storm winds, some species have shown shorter legs which give them a closer and more snug grip on trees and an advantage over longer-legged individuals of the same species.

Comment engagement

Here in Eastern Canada, Quebec and Ontario, the lack of natural winter snow has put quite a damper on our winter sports activities. In the seventies there was an excitement that ski season was about to start with plenty of natural snow accumulation. Then more frequently large thaws would occur, rain episodes that made the smaller ski centres having to close because they couldn't afford snow making infrastructure. Now almost all centres have to make snow to fill in for the lack of natural accumulations.

What about the magnetic pole shift? That has got to be changing the normal cycles of where dolphins and whales migrate to and from! At least for large movements...

The Danish Meteorological Institute publishes daily updates of Arctic sea ice extent including historic data.

Yes I have seen changes through my life time. The winters in the northern US states have gotten warmer, with less freezing before the snow comes. And yes these changes are worried about. I am thinking that at some point we will have another ice age, and it will be a long one, with the ocean conveyor system shutting down, and it becoming colder again. But that will not happen for another 200 years or more in the future.

Living in Barcelona. Here the temperature has changed a lot. It used to be cold when I a child, but now in winter it's not cold at all. Also there isn't snow as it used to be before. It is had what is happening.

So if the Arctic in some distant future stops freezing over even in winter, that would mean we are no longer going to be in an ice age ? I have seen changes in decreasing Summer precipitation in my area and also lenghtening of the growing season or number of average annual consecutive days without frost. Also i have seen some plants shifting the timing of when they are blooming from a warm season to a cooler. Like the forest Cyclamen used to bloom in late July and August, now they bloom in September. The average temp. in these months used to be 64-66°F niw it is 70-72°F in perticularly hot Summers it goes to 75°F. The average September temperature used to be 59°F now it is 62°F.

Every year in Minnesota our droughts are getting worse. You have to know & live closely with the land to see it. Much is changing. Go to the land & observe it. Every year changes further from when we were kids. It’s heartbreaking.

Hi pbs Terra, I live in Eastern WA U.S for most of my life. The type of ecosystem here is called the Okanogan ponderosa pine "high desert." Eastern wa is a mixed forested/ grassland region that is naturally much drier than western WA. Living so close to the Canadian border, I remember growing up of having longer, colder winters. Colder temps and lasting snow on the ground used to continue well into late April / even early May. Then we would see cold temperatures resume in the beginning of September. Summers were milder and temps used to go 85 sometimes 90 degrees occasionally. Now, there is mostly no snow in the valley region for most of the winter. And summer temps frequently go well above 92 F - even above 100. Something that was unheard of when I was little, I'm 33. The brutal wildfire season is routine now. A few years ago, temps reached 112 degrees F, temperatures that are normal in Death Valley CA. For nearly 2 weeks Avista Utilities had to do "rolling blackouts" for up to an hour each because the power grid wasnt designed to withstand that extreme heat. I think, imho that the Rathdrum Idaho Spokane valley aquifer is running out of water. We are simply not getting snow that "remains" at the valley elevations anymore, & not enough to combat the ongoing drought from mountains. Te Spokane region is dependent on snow from the mountains of Northern Idaho. But now it's just drought compounding drought, it's bad. Thank you for this informative video about the abrupt changes in the Arctic! I don't think a "tech fix" will save us. I believe western society is mostly divorced from nature. We can't grieve, really connect with the loss of the enviroment if we never bonded with her. I hate capitalism so 🤷‍♂️ time to throw it in the 🗑 All the best to you!

I'm wondering if it isn't N. Korea's constantly lobbing their test missiles in the ocean I noticed after one of the test a bunch of whales beached themselves in South America. Since whales rely on sound to call each other I'd image that a blast that large under the water would be carried a long ways. The crab season has also been canceled this year because their isn't any. Good God stop destroying the ocean people. Happy there might be hope for them as they migrate away from that area.

Winter here in the Albany NY metro area are producing far less snow than when we first moved out here in the mid 90s. Seasons are shifting, too. Snow rarely shows up until Jan or Feb, and continues into March and sometimes April. Warmest temps still start in July, but now stretch well into September now each year.

My friend who lives in Atlanta Georgia has a bannana tree producing bannanas year round.

Why is no one protesting or doing anything 💔 I at least try to sign petitions for groups….does humanity not realize we will be doomed if we do nothing!

In NJ, other than a brief mid Dec chill, we keep talking about the winter that never arrived.

Yes as a gardener since I was able to walk I have been gardening and have noticed a few changes. Our weather has become so unpredictable and of course, some of my plants get confused and break dormancy early and then get damaged by a late frost because of the warm days throughout the winter causing them to think that's time to grow disturbing them to break their dormancy. Also how warm our summers are becoming shattering documented record highs year after year! Furthermore, this brings me to your question I do worry about our impact on the global ecosystem as a whole. Documented history shows us that evolution happens over millions of years allowing species to evolve and adapt to such changes in weather or climate or whatever is thrown at them. In the present time, this happening in months not years and species are not having the time to evolve to cope with the changes. I fear for our biodiversity and if lose it once they are gone it may never come back. When will humanity realize that the survival of our kind depends on the survival of forests and natural ecosystem health and biodiversity.

in kerala, india, hot days are getting hotter and rainy days bring floods

Could this also be down to the increased noise pollution caused by boats with the increased traffic in the artic circle?

My favorite natural disaster movie is The Day After Tomorrow. Obviously it's dramatized and accelerated for movie magic but uh... well. It's not that far off. We've known we were making a negative impact since 1979 or 1962 if you read Silent Spring. Have we done anything? Accelerated our pollution and destruction of the very eco systems we depend on for our own existence. We are going to suffer greatly going forward. We already see it happening. It's just gonna get worse. We have to adapt or we will experience a huge die off of our species.

It’s the Great Dying II. We are heading into a neo-Proterozoic, maybe back to the Archean. Maybe this is the beginning-end end of complex life. Oh well.

North, to Alaska! Going North - the rush is on. 🎼🎵🎶 Way up North...

Was so mild in Maine this year didn’t even get a chance to go ice fishing none of the ponds froze up… and Penobscot Bay where I go lobster fishing got to 72° on the surface thats hot lobsters 🦞 die at 68..

They can only tell us what we know already. We are in the midst of abrupt, irreversable climate change and the sixth major, and most probably, the final and total extinction of life on earth. The sheer rapidity of this phenomenon is clearly beyond the ability of most of us to understand. And as the geometric rate of change accelerates, so shall the experience of shock to be felt by each of the final living humans.

This is legitimately something to worry about. The ice settled at the poles for a reason. I would hate for the ice to collect somewhere elsewhere due to climate change and our axis of rotation to change in turn.

South central Oregon. Severe drought conditions last 5+ years. Doesn't look to improve.

What late stage capitalism does to a planet is so depressing. Like other commenters I’ve also noticed the climate change from the 90s when I grew up in the middle of Sweden.

And when the high arctic species can't move any further north because they are at the north pole,what happens to them then?

I love the changes that are happening in the Arctic, I wish I could live there to experience those changes myself. The warmer world is coming ❤

Weather here in Vegas has changed in a lot since I moved here in 2015. This issues on the north pole might be irreversible now

My favorite host!

Maybe we should focus on planting trees wherever there is barren land, to keep the earth as cool as possible.

I live in Red Deer Alberta in Canada and I have watched the ecosystem change and struggle to adapt since I was six. Our spruce forests aren't doing as well as they used to, while certain deciduous trees have been doing better or worse. For the first time in my lifetime, the balsam poplar and rowan trees didn't lose all of their leaves before the frost hit because it was unseasonably warm last fall, and wild serviceberries are increasingly rare. Even the indomitable quaking aspen has experienced dieback, and don't get me started on the damage giant hogweed has done to our few remaining meadows. As I mentioned, some trees have been doing better than usual in the past few years. Manitoba Maple has been here since the Europeans brought it west, and in some areas it takes over and smothers while in certain local riparian forests it is actually an important understory tree(no matter where you are in this city, a maple tree is somewhere nearby). This is generally in more preserved ecosystems where the native trees can successfully shade out the maple saplings and the soil conditions are more acidic than it prefers. Less geese showed up to the old sandstone quarry next to Bower Ponds, which is odd because there is a large, safe island right there. I have observed many flowing waters and many forests around here as I have grown up, and something tells me that when the novel ecosystems are healthier than the native ones, nature has lost its balance. The world my future grandchildren grow up in will be wildly different than our own, as some of these novel ecosystems will be in a later stage of their unique process of sucession, and the next generation of ecologists will no doubt discover even more about what little is left of nature by then. If we are even around by then, that is. No doubt the earth would still harbour life, but our legacy of meddling would remain. EDIT: I should mention that on my father's property between Rocky Mountain House and Bentley in the foothills; from the last week and a half in May into June we had what I call an "Alberta Monsoon", which is when it rains for six weeks literally without end. Probably came from all the melted sea ice...

EVERYTHING is ALWAYS changing.

Nice to see PBS Terra finally covering a topic that is happening outside of the US!
