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.

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.
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.

We Are Failing to Protect the Arctic From the Climate Crisis, Report Card Shows
The National Oceanic and Atmospheric Administration (NOAA) released its 14th annual Arctic Report Card Tuesday, and the results are grim.
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.
Reports of extreme snowfall in the Arctic might seem encouraging, given that the region is rapidly warming due to human-driven climate change. According to a new study, however, the snow could actually pose a major threat to the normal reproductive cycles of Arctic wildlife.

Temperatures plunged rapidly across the U.S. this week and around 70 percent of the population is expected to experience temperatures around freezing Wednesday.
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.

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.
Mother Walrus Attacks and Sinks Russian Naval Boat to Protect Her Cubs
Don't mess with a mother walrus!
That's what a team of Russian scientists and naval sailors learned when they tried to land on a remote Arctic archipelago in an inflatable boat, The Independent reported Tuesday.
An international team of scientists says a new way of extracting methane gas trapped in permafrost has the potential to harvest more gas while burning fewer fossil fuels in the extraction process, as Newsweek reported.
Saving the Ozone Layer 30 Years Ago Slowed Global Warming. Can Similar Cooperation Now Solve the Climate Crisis?
The Montreal Protocol, a 1987 international treaty prohibiting the production of chlorofluorocarbons (CFCs) to save the ozone layer, was the first successful multilateral agreement to successfully slow the rate of global warming, according to new research. Now, experts argue that similar measures may lend hope to the climate crisis.
Greenland Ice Sheet Melt Creates Huge Waterfalls, Increasing Concerns About Sea Level Rise
Scientists in the Arctic watched a glacial lake in Greenland turn into a waterfall that drained five million cubic meters of water, or 2,000 Olympic-sized swimming pools, in just five hours, worrying scientists that the world's second largest ice sheet is becoming unstable, according to a new study published in the Proceedings of the National Academy of Sciences.
The fossil fuel industry is driving polar bears to cannibalism.
A three-dimensional portrait of methane concentrations around the world is helping researchers to understand the complex gas, which constitutes the second largest contributor to greenhouse gas (GHG) warming after carbon dioxide.
Russian scientists on an Arctic expedition have discovered, for the first time, methane "boiling" on the surface of the water that is visible to the naked eye. Forget high-tech detection devices, the methane is so pronounced that it can be scooped from the water in buckets, as Newsweek reported.
