A new climate change horror story--melting arctic permafrost may unleash a beastly new level of warming.
It seems that melting permafrost from our normal garden-variety warming may cause methane release and a self-reinforcing cycle that melts more permafrost and releases more methane. Scientists knew this could happen, but it's much worse than previously thought.
What does this mean for fish? Look for mahi mahi in the Bering Sea and Atlantic cod in a museum in a century if this proves true. Maybe take a few pictures of your favorite cold water fish for your great-grandchildren to look at, it might be the only place to see them.
