I enjoy travelling http://ghettotube.in.net ghettotube.com The IPCC draft also says the planet may be somewhat less sensitive than expected to a build-up of carbon dioxide in the air. A doubling of atmospheric carbon dioxide levels from pre-industrial times is likely to mean an eventual temperature rise of between 1.5 and 4.5 C (2.7-8.1F), down from 2.0 to 4.5 (3.6-8.1F) estimated in 2007, it says.
