As the holidays conclude and the new year beckons, its time for a bit of summing up and a new beginning.
Today's post highlights a recent talk by Richard Alley, author of The Two-Mile Time Machine: Ice Cores, Abrupt Climate Change, and Our Future and Chair of the National Research Council's report on Abrupt Climate Change. We'll close out this segment on climate change with our take on the events at Copenhagen. Stay tuned.
Alley's talk, available here, surveys data covering millions of years in order to clearly, interestingly and entertainingly show how CO2 is a key part of the Earth’s climate regulatory system or -- in Alley's terminology -- how CO2 is the 'biggest control knob.'
