Global warming… Copenhagen 2009… Waterlevels rising…
The answer, apparently, is 350!
OK, so what’s it all about? I didn’t know that that number had any kind of significance until a little earlier today, when I read about it on the No Impact Man blog.
350 is the red line for human beings, the most important number on the planet. The most recent science tells us that unless we can reduce the amount of carbon dioxide in the atmosphere to 350 parts per million, we will cause huge and irreversible damage to the earth.
When the object of the countries participating in the next climate conference (the one in Copenhagen, thanks to Ms. Hedegaard) is to agree on 450 (optimistic) or 550 (much more likely), it dawns on you why some people out there suddenly think they need to build an entire organisation around the number: 350.
The post on No Impact Man is full of good and solid references.
