A Climate Success Story

The Dish

Ben Richmond relays some rare good news about climate change:

The Montreal Protocol, already hailed by Kofi Anan as “perhaps the single most successful international agreement to date,” can add another feather to its cap. In addition to slowing the growth of, and then shrinking, the hole in the ozone layer, the researchers have used computer models to demonstrate that without the reduction of CFCs, the environmental changes projected for the next decade – already expected to be really bad – would be twice as severe.

It certainly wasn’t part of the reason for ratifying the Montreal Protocol, which was aimed specifically at reducing the hole in the ozone layer over Antarctica, but it’s another positive result – collateral benefit, if you will. “We dodged a bullet we did not know had been fired,” said Richard Seager, a scientist at Columbia University’s Lamont-Doherty Earth Observatory who coauthored the study.
