Today's News on Carbon and Climate

Evidence of a strong correlation between CO2 levels in the atmosphere and global temperature continues to mount:

A meticulous new analysis of Antarctic ice suggests that the sharp warming that ended the last ice age occurred in lock step with increases of carbon dioxide in the atmosphere, the latest of many indications that the gas is a powerful influence on the earth’s climate.

This is a complicated matter, having to do with how we date the air bubbles trapped in  polar ice and other arcane questions. But as the dating gets better, the link between temperature and CO2 levels keeps getting firmer.
