Event

The discovery of the hole in the ozone, first made in the late 1970s, is like the grandpappy of modern climate science: the first inkling that human activity has the power to seriously screw up the planet's atmosphere. In the mid-1980s Susan Solomon, a Berkeley-trained chemist, figured out that chlorofluorocarbons were a contributor to ozone depletion. Her research eventually led to the Montreal Protocol, an international treaty banning ozone-depleting substances (for example, the strawberry fumigant methyl bromide). Solomon, who spent most of her career at NOAA, is now at MIT, where she continues her research on climate change. Tonight Solomon delivers the annual Fred Keeley Lecture on Environmental Policy, which kicks off an intensive one-day conference on climate change bringing together scientists and authors of national repute.
