Arctic Methane and Permafrost Challenge

What are the current methane emissions in the Arctic and what are the sources and sinks? Will the fraction of the carbon permafrost feedback increase in the future? Why do we see rapid changes in permafrost not followed by a commensurate net rise in methane emissions? What can we learn from the increasing number of satellite observations over the Arctic high latitudes?

NASA and ESA are launching a transatlantic initiative to address these and other questions and help solving the Arctic Methane and Permafrost Challenge.
