RealClimate » 650,000 years of greenhouse gas concentrations 650 000 : "The latest results from the EPICA core in Antarctica have just been published this week in Science (Siegenthaler et al. and Spahni et al.). This ice core extended the record of Antarctic climate back to maybe 800,000 years, and the first 650,000 years of ice have now been analysed for greenhouse gas concentrations saved in tiny bubbles. The records for CO2, CH4 and N2O both confirm the Vostok records that have been available for a few years now,"

Great news -- more real science on climate change.

"To quote Richard Alley "Whether you're a physicist, a chemist, a biologist, a geologist, or any other "ist" studying the Earth system, there is something in these data that confirms much of your understanding of the planet and then challenges some piece of your understanding". It's all very exciting (for us 'ists' at least!)."
