Submission + - Clam Shells Provide More Global Warming Evidence
farker haiku writes: Scientific American is reporting that 'A new method for analyzing fossilized shells confirms link between carbon dioxide levels in the atmosphere and warmer oceans'. The article goes on to say that "The finding adds yet more weight to the contention that greenhouse gases drive climate change, and bode ill for the present increases in atmospheric concentrations of such gases. "It supports the notion," Eiler says, "that you can use simple radiative balance arguments — that is, the greenhouse effect to relate atmospheric chemistry to global temperature."
