Arctic winters are meant to be frigid, but because of rising temperatures and climate change, they aren't cold enough. The permafrost, the thick subsurface layer of frozen soil that stores one of the world's largest natural reserves of carbon, is thawing. As it does, it releases potent greenhouse gases that accelerate climate change. European scientists have now found that resettling massive herds of large herbivores could combat this effect and save up to 80 percent of all permafrost soils around the globe until 2100.
The coronavirus crisis has spread far and wide, indiscriminately affecting civilians, celebrities, sports stars and politicians and touching all parts of society. Now, the pandemic is impacting scientists on a large research expedition in the frozen Arctic Ocean, delaying critical climate research.

The climate crisis wreaks havoc on animals and plants that have trouble adapting to global heating and extreme weather. Some of the most obvious examples are at the far reaches of the planet, as bees disappear from Canada, penguin populations plummet in the Antarctic, and now polar bears in the Arctic are struggling from sea ice loss, according to a new study, as CNN reported.
In the Northern Hemisphere, temperatures were, on average, 2.7 degrees Fahrenheit warmer than normal last month, making it the warmest January on Earth since comprehensive records have been kept starting 141 years ago, according to new data from the National Oceanic and Atmospheric Administration (NOAA), as The Guardian reported.
'This Is History in the Making': Cherokee Nation Is First U.S.-Based Tribe to Preserve Seeds in 'Doomsday Vault'
The Cherokee Nation will save seeds from the "three-sisters" crops in the Arctic "doomsday vault," making it the first Native American tribe to ensure culturally emblematic crops will be preserved for the future, as The Guardian reported.
Current estimates of carbon emissions from melting Arctic permafrost rely on a model of a gradual melt. New research has found abrupt thawing of permafrost which means carbon emissions estimates should be doubled. The rate at which permafrost is thawing in the Arctic is gouging holes in the landscape, according to a new study published in the journal Nature Geoscience.

Part of Joellen Russell's job is to help illuminate the deep darkness — to shine a light on what's happening beneath the surface of the ocean. And it's one of the most important jobs in the world right now.
The world awakened to the hole in the ozone layer in 1985, which scientists attributed it to ozone-depleting substances. Two years later, in Montreal, the world agreed to ban the halogen compounds causing the massive hole over Antarctica. Research now shows that those chemicals didn't just cut a hole in the ozone layer, they also warmed up the Arctic.
