he had shaken up the prevailing consensus that the oceans were massive enough to soak up any amount of excess of carbon released on earth. Not so, Revelle discovered; the peculiar chemistry of sea water actually prevents this from happening.
Now, he said, humans have begun a “vast geophysical experiment.” We were about to burn, within a few generations, the fossil fuels that had slowly accumulated in the earth over the past 500 million years. Burning so much oil, gas, and coal would release massive amounts of carbon dioxide into the atmosphere, where it would trap heat that otherwise would escape into space. Earth’s temperature could rise, causing polar ice to melt and sea levels to rise, flooding the earth’s coastal regions.
