I am Sue Natali, Associate Scientist at Woods Hole Research Center (http://whrc.org/staff/susan-natali/). I’ve been working in the Arctic since 2008, and my research has involved fieldwork across Alaska and in northeast Siberia. I study the effects of climate change on arctic ecosystems and the consequences of these changes for carbon cycling. My research addresses these questions: How do climate change and fire affect permafrost thaw? How do plant communities respond to warmer temperatures and ground thaw? How does permafrost impact soil moisture? What are the impacts of these changes on carbon cycling? What are the implications of permafrost thaw for global climate? I’ll be back at 1 EDT to answer all your permafrost and climate change questions. Ask Me Anything! The AGU AMA series is conducted by the Sharing Science (http://sharingscience.org) program.
