Arctic Sinkholes I Full Documentary I NOVA I PBS

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.

How did the mammals get that far underground? Let me guess a sinkhole. That is evidence of a thawing freezing cycle. Seems almost natural we are thawing right now.

@mudfossiluniversity Yıl önce

I am a fossil researcher and that requires understanding Earth features which very few do.I did vids on these sinkholes when a Fla man was sucked in (2013). A Japanese researcher told me the Russians wanted to disscuss these holes with me....at the time there was 13. I spoke with the Russians (I think Academy of Science?? not sure long ago) about these holes as I studied them many years. I understand them and the gases and what can and cannot be done. This is a very dynamic situation we are facing. Under "Fair Use" I believe it is permitted to comment using your content (even copyright).

I lived in Anchorage in the 70s, and I recall local news reporting on permafrost thaw. The main complaint was the smell and the increased mosquito harvest. It was worrisome that the groundwater was thawing the permafrost and scientists we're studying it. I would say that this mega methane leakage is far greater than any methane produced by cattle around the world.

Earth goes through its cycles. These cycles are affected by the cycles of the Sun and of the Universe. Humans have no control of these cycles. At one time, Antartica was warm and thrived with life. For most of its exsistence, the Earth's climate did not support any life. Humans have a hard time realizing and appreciating how delicate and short our existence here has and will be.

@leftear99 6 aylar önce

The antarctic doesn't have the same geologic composition underneath it, so no, it's not exactly happening there as well. The impacts we're seeing there include ice shelf collapse and current decline. We are absolutely contributing to the rate at which warming occurs, but the observations differ across the globe.

@OgdenM 6 aylar önce

@@leftear99, you mean so far. We really don't know much about what is under the ice in Antarctica. There very well could be frozen biological matter deep under the soil under the ice.... And probably is since the land used to be elsewhere on the planet and much warmer. Sure, we probably have a few hundred years before the ice melts enough for the permafrost to start melting.

They've done the least to contribute to it. Glad to see the innovations that can help them continue to live where they've lived for thousands of years.

@nobody.of.importance 6 aylar önce

It makes sense if you think about it. Plants grow on the surface, get covered by snow, said snow gets packed down into ice, the plants are broken down by bacteria into methane, and trapped as a giant gas bubble. Ice melts, pressure overwhelms the strength of the ice and the whole thing explodes.

These methane bubbles occur in New Orleans Louisiana, USA area as well. Although they found some to be butane gas escaping from fractures in the natural salt mines where oil is stored pre-refining. Some have cause explosions and fires & evacuations - even of a permanent evacuation of an entire city. Accidental drilling into the wall of a salt mine can cause the escape of the butane gas.

This video is very well done and, like most, is very good at pointing out problems. How about we start studying solutions? For example, you don't have to dig very deep in the ground to find cool, comfortable temperatures. I'll bet HUGE amounts of carbon producing energy are used to simply to cool homes and businesses. Why not demand that underground piping systems be used to cool homes instead? Or make all homes subterranean (which would leave the ground above the home available to grow food, or install solar panels)? Most homes in California are built on cement slabs. Pipes imbedded in the slabs under the constant shade of the house may provide enough cooling for the home during the day.

The land bridges under water near Norway, Greenland, as well as the Bering strait have been sinking allowing more salt water into the Arctic Ocean, having a tremendous effect on the amount of sea ice that would form leading to less ice that protects Arctic coastlines and ice that would reflect more sunlight. Thus, leading to more warming in the Arctic. There's lots of natural phenomena that's changing the climate.

Excellent information. This gives community leadership the opportunity to develop and implement mitigation strategies to help community membership survive into the future... even if it means relocating the whole community.

i think its a safety mechanism, feels like at some point the clock is running and maybe we find a global solution or travel mankind to other planets. if not, its over. its like a test if we are somewhat worthy. its like in a game, after a huge progression there are always tests to see if you can substand them and this feels like one.

When I worked in Dead horse in the mid 70's there were miniature ponds as far as the eye could see in the permafrost. I didn't notice any change in the size or quantity of the ponds during my four year stay. It looked exactly like the ones shown on this show.

But that's just it, they aren't miniature ponds anymore. They are lakes.

You can still see frozen ice trapped in the walls of those craters. How does an increase in atmospheric temperatures cause the permafrost to thaw from the bottom up?

Just thought of that trees eat carbons and such, so... meaning that we do possibly need more trees that what we have, to take up all the carbon in the air? Possibly then stabilize the atmosphere. Also, trees stabilize the ground/earth, so there's less of these sinkholes happens.

If you do the research, the Arctic is situated on top of what used to be a tropical rain forest. I believe it was before the last pole shift. Seems to me what's happening now is that as the region is warming up, that whole area that was once lush with life (before being re-situated, I suppose) is now beginning to decompose. If there was as much life thriving there before it became polar territory, this "thaw" is just the beginning of what could turn out to be a frighteningly enormous problem.

@nicksshitbro 11 aylar önce

This would coincide with the theory that the poles are currently shifting again, as per the 25,600 year cycle.
