i wonder if all those recently eaten thanksgiving dinners replete with turkey, stuffing, mashed potatoes and gravy have anything to do with it...?
Current levels of the greenhouse gases carbon dioxide and methane in the atmosphere are higher now than at any time in the last 650,000 years.

That is the conclusion of new European studies looking at ice taken from 3km below the surface of Antarctica.

The scientists say their research shows present day warming to be exceptional.

Other research, also published in the journal Science, suggests that sea levels may be rising twice as fast now as in previous centuries.

[...]

"One of the most important things is we can put current levels of carbon dioxide and methane into a long-term context," said project leader Thomas Stocker from the University of Bern, Switzerland.

"We find that CO2 is about 30% higher than at any time, and methane 130% higher than at any time; and the rates of increase are absolutely exceptional: for CO2, 200 times faster than at any time in the last 650,000 years."
