In the Arctic, enormous releases of methane, a potent greenhouse gas, threaten the climate.
Colossal explosions shake a remote corner of the Siberian tundra, leaving behind massive sinkholes. In Alaska, a huge lake erupts with bubbles of inflammable gas. Scientists are discovering that these mystifying phenomena add up to a ticking time bomb, as long-frozen permafrost melts and releases vast amounts of methane, a potent greenhouse gas. What are the implications of these dramatic developments in the Arctic? Scientists and local communities alike are struggling to grasp the scale of the methane threat and what it means for our climate future.

Discover how scientists are trying to capture methane in this short from NOVA and PBS Terra: https://bit.ly/3HGAfP6
Global warming is bs.
Are we all just supposed to believe this crap. The more carbon in the atmosphere the better plants do. The better plants do the more oxygen is produced. We have been tricked into believing this is a bad thing. Why do we have the lowest levels of carbon in our atmosphere right now than has ever been on earth. This is a fact. This is a big tactic to scare everyone into submission.
One thing a lot of people overlook when it comes to methane, is that yeah, it's relatively short lived compared to CO2…but when it decomposes, it decomposes into C02 and keeps on warming at a slower rate…
A beautiful natural occurrence on Earth that the eco terrorists will blow out of proportion and blame on man. Mother Earth is much more powerful than anything man can or will do. Embrace nature, it’s awesome and has been happening for millions of years
So if all these carbon deposits happened millions of years ago, long before man and oil production and were at levels much higher that we see today, how is climate change man made?
“Unusually high levels of methane”. So….its a fart? 🌎💨
Pretty obvious. Why isnt this included in climate change models?
em cám ơn chương trình đã chia sẻ video rất hay và bổ ích ❤❤
That was funny Scientist's are like professionally educated lil kids ok I'll light it you poke it let's see what happens
need to figure out a way to put that methane to use – help the environment, help the people, get rich
Methane and all other hydrocarbon production on earth is ABIOTIC. One of the biggest lies ever pushed was convincing you that its the result of compressed biological matter that's been folded into the earth.
You mean it was once warmer and ice took over and killed millions and it's melting? OMG what are we to do? We're gonna drown 😂😡
Too bad PBS is just some propaganda arm of the government now. Thanks Obama!!!
How many billions will become non existent when this methane explodes? Humans are not the only problem, we have 40 + or _ volcanoes erupting daily. Are we doomed, who knows, but what the climate terrorists want people to believe they have caused this, I doubt that is what has happened. This is a normal cycle, live with it as long as you can, you will all come to an end soon enough. This is going to happen, not in my time but soon in the future.
its no secret that sinkholes are caused by sink-o-di-mayo, due to mexicanity borders…..we need to stop this illegal sink-o-di-mayo crossing
Just how the human body heats up to kill infections, the earth is heating up to rid itself of us.
thanks for Asher knowing what one does not know about the world
They are really focusing on the past. Wouldn’t a warmer climate mean that more animals and vegetation can grow there? This video almost seems sponsored by some lobbyists.
Thank goodness we can most all of us go vegan and let more than 40% of ice free land be rewilded and most importantly stop the deforestation. The trillions of trees are sequestering carbon.
Im not living in Alaska or in any place near that area but understanding this whole thing made me worry and sad about the future and the people living near that area.. I hope more people will/can watch this video to raise awareness. This is very informative and important, my kids are watching with me right now.. 🥺❤
pack it up guys, earth's blowing up, we're done.
You don't have to know everything that goes on the planet. Just go back to your home and enjoy life, and the earth will take care of itself, probably you need to take care of yourself also. So don't worry about Planet Earth.
I have a theory. The massive earthquake in Japan March 2011 was so massive it altered the earths axis a few degrees more than it was.
The storm patterns shifted , climate rose and fell depending on the location on earth in many many areas.
It's worth looking into. My prayers for the wonderful people ,our friends of the north. May God bless you and keep you safe.
" enormous releases of methane, a potent greenhouse gas, threaten the climate." BULLSHIT! Stop with the Propaganda!
the sad part about this is that a man has put all his life into researching this and solving this single handedly without getting any help from the government despite multiple efforts ( look up about Pleistocene Park project)
Humans are not in charge of weather unlike the media propaganda and musk bezos buffett gates etc making billions on the business of climate change while we pay and pay just like the ozone conspiracy created by do Pont wake up people don't be sheeple
I miss the ancient aliens series. It pretty much explains everything that happens on earth.
The earth is a dynamic living organism under constant change, with cycles within cycles upon cycles beyond cycles, and connected with the moon, the sun and other planetary bodies. no need for sensationalist hysteria.
its complex and much of it probably beyond our current understanding. even your best theoretical models are incomplete and probably contain errors and fudge factors.
