climateprogress.org — World carbon dioxide levels jump 2.3 ppm in 2008 to highest in 650,000 ? if not 20 million ? yearsNOAA?s Global Monitoring Division reports that global concentrations of the primary heat-trapping greenhouse gas, carbon dioxide, jumped 2.28 ppm in 2008.

Reality mongering.The last time CO2 levels were this high, sea levels were 80 feet higher.Sure 2500 ppm is OK, if you're a c**kroach. On Earth, it would be temperatures 20F warmer, probably 30F over much of U.S. Oh, and sea levels 250 feet higher. Plus one third the planet desert. Lasting 1000 years.

Their study finds that five percent of all ecosystems cannot adapt more quickly than 0.1 C per decade over time. Forests will be among the ecosystems to experience problems first because their ability to migrate to stay within the climate zone they are adapted to is limited. If the rate is 0.3 C per decade, 15 percent of ecosystems will not be able to adapt. If the rate should exceed 0.4 C per decade, all ecosystems will be quickly destroyed, opportunistic species will dominate, and the breakdown of biological material will lead to even greater emissions of CO2. This will in turn increase the rate of warming" --Leemans and Eickhout (2004), "Another reason for concern: regional and global impacts on ecosystems for different levels of climate change," Global Environmental Change 14, 219-228We have warmed 0.2 C/decade for the last two decades."Few seem to realise that the present IPCC models predict almost unanimously that by 2040 the average summer in Europe will be as hot as the summer of 2003 when over 30,000 died from heat. By then we may cool ourselves with air conditioning and learn to live in a climate no worse than that of Baghdad now. But without extensive irrigation the plants will die and both farming and natural ecosystems will be replaced by scrub and desert. What will there be to eat? The same dire changes will affect the rest of the world and I can envisage Americans migrating into Canada and the Chinese into Siberia but there may be little food for any of them." --Dr James Lovelock's lecture to the Royal Society, 29 Oct.

Great time to be a CO2 loving plant.
