I was just reading about the methane clathrates. Apparently the warming of the oceans is hastening their destabilization, and methane is a much worse greenhouse gas than Co2.

U.S. Temperatures 2008: Back to the Future?

worldclimatereport.com

The data are just in from the National Climatic Data Center and they show that for the year 2008, the average temperature across the United States (lower 48 States) was 1.34ºF lower than last year, and a mere one-quarter of a degree above the long-term 1901-2000 average. The temperature in 2008 dropped back down to the range that characterized most of the 20th century.

Figure 1 shows the U.S. temperature history from 1895 to 2008. Notice the unusual grouping of warm years that have occurred since the 1998 El Niño. Once the 1998 El Niño elevated the temperatures across the country, they never seemed to return to where they were before. Proponents of catastrophic global warming liked to claim that is was our own doing through the burning of fossil fuels, but others were more inclined to scratch their heads at the odd nature of the record and wait to see what happened next.
