Thawing Permafrost Could Release Antibiotic Resistant Bacteria and Undiscovered Viruses
When considering the implications of thawing permafrost, our initial worries are likely to turn to the major issue of methane being released into the atmosphere…
New Understanding of the Arctic’s Carbon Cycle – How Carbon Is Transferred Between Land, Ocean, and Atmosphere
New research from UMass Amherst shines light on poorly understood processes of how carbon dissolved in Arctic rivers affects our world. In a pair of…
Significant Thawing of Permafrost Projected in Daisetsu Mountains in Japan
Areas with ground temperatures that remain below 0°C for more than two years are referred to as permafrost, and approximately one-quarter of the Northern Hemisphere…
Arctic Rotifer Lives After Being Frozen for 24,000 Years in Siberian Permafrost
Bdelloid rotifers are multicellular animals so small you need a microscope to see them. Despite their size, they’re known for being tough, capable of surviving…
Climate Change Concerns Rise As Cave Deposits Show Surprising Shift in Permafrost Over the Last 400,000 Years
Study finds Earth’s frozen surfaces became less susceptible to thawing, potentially locking in more carbon than expected. Nearly one quarter of the land in the…
International Research Team Begins Uncovering Mystery Lurking Beneath the Arctic Ocean
New study on submarine permafrost suggests locked greenhouse gases are emerging. Something lurks beneath the Arctic Ocean. While it’s not a monster, it has largely…
Horses Can Save the Permafrost – Here’s How
New Mitigation Strategy Bears Great Potential Permafrost soils in the Arctic are thawing. As they do, large additional quantities of greenhouse gases could be released,…
Stunning Animation Shows Permafrost Changes in the Arctic Due to Climate Change
Permafrost plays an important role in the global climate and is also one of the components of the Earth system that is most sensitive to…
Fears of Massive Greenhouse Gas Release From Old Carbon Reservoirs Are Overblown
Permafrost in the soil and methane hydrates deep in the ocean are large reservoirs of ancient carbon. As soil and ocean temperatures rise, the reservoirs…
Arctic Permafrost Turning Into a Carbon Source – Holds More Carbon Than Has Ever Been Released by Humans
Arctic regions have captured and stored carbon for tens of thousands of years, but a new study shows winter carbon emissions from the Arctic may…
Arctic Shifts to Carbon Source – Stunning Reversal After Capturing Carbon for Tens of Thousands of Years
A NASA-funded study suggests winter carbon emissions in the Arctic may be adding more carbon into the atmosphere each year than is taken up by…
Thawing of the Far Northern Permafrost Has Scientists Worried
Permafrost in the coldest northern Arctic — formerly thought to be at least temporarily shielded from global warming by its extreme environment — will thaw…
Thawing Permafrost is Changing Arctic and Subarctic Lakes and Ponds
As ice the melts, the organic carbon found in permafrost is being released once again after ages of confinement in the soil. It is making…
Low Arctic Snow Cover Could be Trouble for Permafrost
June Arctic snow cover in the Northern Hemisphere dropped by almost 18% per decade over the last 30 years. This drop in snow cover will…
