Climate, sea level, and ice sheets have always changed, and the changes observed today are less than those of the past. Climate changes are cyclical and are driven by the Earth's position in the galaxy, the sun, wobbles in the Earth's orbit, ocean currents, and plate tectonics. In previous times, atmospheric carbon dioxide was far higher than at present but did not drive climate change. No runaway greenhouse effect or acid oceans occurred during times of excessively high carbon dioxide. During past glaciations, carbon dioxide was higher than it is today. The non-scientific popular political view is that humans change climate. Do we have reason for concern about possible human-induced climate change?Nuclear Fallout - Mark Steyn - The Corner on National Review Online
Climate change: We can afford to save the planet - Salt Lake TribuneFour months ago another UN worker also believed to be British fell from a similar height in the same building, it has been reported.Hmm. I'd advise Mohammed El Baradei's surviving colleagues to take the elevator, but then again the aunt of Kofi Annan's discredited sidekick Benon Sevan fell to her death accidentally stepping into an empty elevator shaft shortly before she was due to be questioned about the Oil-for-Food scandal. If you work at the UN, get a gig on the ground floor.
The bad news? Turns out that 450 ppm is so 2005.
In the past four years, climate scientists, led by NASA's James Hansen, have dramatically altered the goal. To avoid the collapse of the continental ice-sheets and a dangerous rise in sea levels, many scientists [do these scientists have names?] are now saying we have to get down to 350 ppm, and quickly.
