Acidifying oceans spell bleak marine biological future 'by end of century', Mediterranean research finds

ScienceDaily (2010-08-25) -- A unique 'natural laboratory' in the Mediterranean Sea is revealing the effects of rising carbon dioxide levels on life in the oceans. The results show a bleak future for marine life as ocean acidity rises, and suggest that similar lowering of ocean pH levels may have been responsible for massive extinctions in the past.
