Permafrost in Alaska
A warming climate is causing some of Alaska's permafrost to thaw, with impacts on people and the environment.
Temperatures are rising, snow and rainfall patterns are shifting, and more extreme climate events – like heavy rainstorms and record high temperatures – are becoming more common. Many of these observed climate changes are linked to rising levels of greenhouse gases in our atmosphere, caused by human activities. EPA’s indicators provide evidence of these changes and their impacts on people and the environment. EPA partners with dozens of data contributors to compile and keep these indicators up to date.
