Greenland ice cores show industrial record of acid rain, success of U.S. Clean Air Act
Description: Forty-five years ago, acid rain was killing fish and dissolving stone monuments on the East Coast. The rise and fall of acid rain is a global experiment whose results are preserved in the geologic record.
