This is a very useful site which I would really recommend to anyone with an interest in Climate Change and Global Warming to check out. I came across it yesterday whilst doing a little bit of update research for one of my latest short stories.
The site basically monitors current carbon dioxide and global temperature levels in relation to Climate Change, and the levels of CO2 reported for July 2011 stand at 392.39 parts per million. This means we are already above the acceptable levels for the Holocene climatic period: 350 ppm. My understanding is that, in order to avoid catastrophic climate change, CO2 levels will need to be reduced below 350 ppm. I’m also led to understand that once we exceed 450 ppm, then the earth’s positive feedback systems will start to kick-in. Looks like we’re not far off it then!
The site also has some interesting FAQs and articles about climate change, as well as some links to other sites that provide more information. Well worth a look. (I’ll be posting a permanent link to this site on the blog I think.)
