Seth Spawn is an arctic ecologist at the Woods Hole Research Center whose research explores how arctic ecosystems respond to and amplify the effects of climate change through the “permafrost-carbon feedback”. Permafrost – permanently frozen soil – stores vast quantities of fossil carbon that, when thawed, is transformed into carbon dioxide and methane by microbes and released to the atmosphere. These emissions further amplify global warming and have not yet been accounted for in global climate models. Seth will give an overview of the Arctic carbon cycle and its not-so indirect effects on the places we call home.
