From Daniel Doniger at the NRDC last week, a reminder on the 25th anniversary of the signing of the Montreal Protocol, that Republicans and Democrats in this country, including the Reagan and Bush administration, allied to support an international treaty to save the ozone layer.
Millions of lives saved. Hundreds of millions of cancers averted. Agricultural disaster avoided. These are big achievements.
In Doniger's post is a presentation from Dr. Paul. A. Newman of NASA, discussing what he calls "The World Avoided." He points out that ozone, like carbon dioxide, is a trace gas, found in very small amounts in the atmosphere -- 10 parts per million for ozone, 390 ppm for CO2.
We as a species have proven we can take action to avert atmospheric disaster. It's a fact.
