Batagay (aka Batagaika) Crater goes by many names. Scientists call it a retrogressive thaw megaslump; the internet may know it best as the Doorway to the Underworld. And since it opened up in the Siberian permafrost over half a century...

If you've ever heard about things like mammoths being found in permafrost, you may have an image in your head of what that looks like. But you might be wrong! So let's talk about what permafrost really is, why it's so important, and...

A mysterious, large feline roamed Eurasia during the last ice age. Its fossils have been found across the continent, and it’s been the subject of ancient artwork. So what exactly were these big cats?

Nunalleq, a village in what’s today southwest Alaska, seemed to have thrived during the Little Ice Age. How did this village manage to survive and prosper during this time period? And what caused this period of climate change in the...

In June 2022, a gold miner in the Canadian Yukon made a remarkable discovery. While working on the traditional lands of the Tr'ondëk Hwëch'in First Nation, he uncovered the exceptionally well-preserved, frozen remains of a wooly mammoth...

For the first time, we are forced to consider the real risk of destabilizing the entire planet, says climate impact scholar Johan Rockström. In a talk backed by vivid animations of the climate crisis, he shows how nine out of the 15 big...

What will happen to the planet if climate change melts what's left of Arctic permafrost? Shedding light on this overlooked threat, Arctic geologist Sue Natali reveals the true danger of heating up the iciest place on the planet: the...

Science probably isn’t the first thing that pops into your head when you think about Alaska, but it has a lot to offer when it comes to learning about the world, from cold corals to our behavior.

Tiny creatures called rotifers seem to have no problem continuing their lives after waking from a refreshing 24,000-year nap. And DNA samples from goats that lived 30,000 years ago tell us a bit about how humans were managing them back...

Megatsunamis are not only much larger than your average tsunami, they also form under different conditions. Good news: they're extremely rare. Bad news: they might not be for long.

SciShow News explains how Wikipedia has been used to track, and even predict, outbreaks of disease all over the world, and then introduces you to the most complete naturally mummified bison ever found.

Rachel Sussman shows photographs of the world's oldest continuously living organisms -- from 2,000-year-old brain coral off Tobago's coast to an "underground forest" in South Africa that has lived since before the dawn of agriculture.

It’s the dream of kids all around the world to see giant beasts walk the Earth again. Could -- and should -- that dream be realized? Hendrik Poinar talks about the next big thing: the quest to engineer a creature that looks very much...

There's two times more carbon in the earth's soil than in all of its vegetation and the atmosphere -- combined. Biogeochemist Asmeret Asefaw Berhe dives into the science of soil and shares how we could use its awesome carbon-trapping...

Arctic sea ice is melting at record levels throwing global weather into chaos and contributing to extreme warming. There are three MAJOR climate systems that may be approaching their tipping points, and their future depends, in part, on...

Science Kids Arctic Tundra Biome V1-0005

The video highlights the impact of climate change on the Arctic tundra, emphasizing how a longer summer disrupts the food chain, affects wildlife, and leads to environmental challenges. It...

Pupil outcome: I can describe the Arctic Tundra and explain what life is like there. Key learning points: - The tundra is a treeless landscape found at high latitudes. - In the winter the tundra is frozen and dark and experiences 24...

A “tipping point” is when a system, with just a small amount of additional energy, is pushed from one stable state to another suddenly and dramatically. This can be a chair falling backwards. Or it can be a major earth system collapsing....

From the wooly mammoth to the passenger pigeon, extinct species once maintained the balance of the earth’s delicate ecosystems. But human interference has resulted in dramatic loss of biodiversity. Can science restore what has been lost?...

Arctic air is warming, causing scientists to worry that melting arctic ice and snow could also lead to a sudden permafrost thaw and release of carbon dioxide (CO2) and methane (CH4) that forms a climate tipping point or feedback loop....

Los volúmenes más elevados de metano de la Tierra se encuentran congelados a gran profundidad bajo tierra. Aprende cómo el calentamiento global podría fundir estos depósitos y dar comienzo al proceso irreversible que predijo...
