The Montreal Protocol was negotiated in 1987 to save the ozone layer, but the treaty has yielded a second environmental benefit: It has dramatically slowed down the rate of global warming.Emphasis added. Read the rest.
Just how much it has helped has been calculated by a team of scientists in the Netherlands and the United States. For the world's climate, they found, the benefits of phasing out the use of ozone-depleting chemicals have already been larger than the projected greenhouse-gas reductions called for under the more conspicuous Kyoto Protocol.
"I think our party has got into a mess on the environment. As a practical matter of politics, nobody knows what (Kyoto) is or what it commits us to." Michael Ignatieff
