The Department of the Interior, the Environmental Protection Agency, and the National Oceanic and Atmospheric Administration recently announced four collaborative landscape partnerships to make important lands and waters more resilient to climate change . Federal agencies will work with local, state, and tribal organizations in southwest Florida, Hawaiʻi, Washington, and the Great Lakes.

Physical Climate, Mitigation, Carbon Cycle, Arctic
A new synthesis published in Nature suggests that thawing Arctic permafrost will release greenhouse gases gradually, rather than in a sudden "bomb". The gradual rate of these natural emissions may give society more time to adapt to their effects, but they remain a challenge for climate mitigation .
