Climate change's "evil twin" -- ocean acidification -- has been increasing at a rate unexpected by scientists, says Dr. Jane Lubchenco, head of the National Oceanic and Atmospheric Administration (NOAA).

Lubchenco told he Associated Press that surface waters, where excess carbon dioxide from the atmosphere has been concentrating, "are changing much more rapidly than initial calculations have suggested." She warns, "It's yet another reason to be very seriously concerned about the amount of carbon dioxide that is in the atmosphere now and the additional amount we continue to put out."
