On Saturday, I noted the AAAS meeting report on climate change by Christopher Brown.Climate change worsens more rapidly than IPCC anticipated Here's a bit more on Christopher Field's report from MSNBC:
Carbon emissions have been growing at 3.5 percent per year since 2000, up sharply from the 0.9 percent per year in the 1990s..."It is now outside the entire envelope of possibilities" considered in the 2007 report of the International Panel on Climate Change...The largest factor is the widespread adoption of coal as an energy source... "and without aggressive attention societies will continue to focus on the energy sources that are cheapest, and that means coal." Past projections for declines in the emissions of greenhouse gases were too optimistic, he added. No part of the world had a decline in emissions from 2000 to 2008.
Anny Cazenave of France's National Center for Space Studies [reported] that improved satellite measurements show that sea levels are rising faster than had been expected... Rising oceans can pose a threat to low level areas such as South Florida, New York and other coastal areas as the ocean warms and expands and as water is added from melting ice sheets...And the rise is uneven, with the fastest rising areas at about 1 centimeter — 0.39 inch — per year in parts of the North Atlantic, western Pacific and the Southern Ocean surrounding Antarctica...
