Despite scientists’ efforts, gaps in Arctic carbon monitoring and modeling of permafrost thaw are limiting our ability to address the climate crisis. These gaps create uncertainties in our estimates of …
In the first video we watched for this course, we described permafrost as a large carbon reservoir. Permafrost stores an estimated 1.4 trillion tonnes of carbon—almost double the amount already …
The United Nations Intergovernmental Panel on Climate Change has published numerous reports warning that passing 1.5 degrees Celsius of average global warming will have catastrophic repercussions for the planet—a threshold …
3.6 million people currently live in areas at risk of infrastructure damage due to climate hazards caused by permafrost thaw. As warming causes once-frozen permafrost to thaw, the ground can …
The vast, diverse northern permafrost zone spans from the Canadian High Arctic to sub-Arctic Alaska and boreal Canada, to mountains in the lower 48 U.S. States, much of Russia, some …
Depending where you live, the Arctic region may seem distant or isolated. In reality, the Arctic is home to millions of people and is connected to the rest of the …
Now that we know what and where permafrost is, what do those landscapes look like? Natalie Baillargeon and Anneka Williams have both visited field sites in Alaska’s Yukon-Kuskokwim Delta, a …
Permafrost is perennially frozen earth composed of substrate, including soil, gravel, sand, and decayed plant and animal material known as organic matter. Permafrost can contain large amounts of ice (up …
