its nothing compared to dinosaur farts

they created a greenhouse effect like no other

Lots of guesswork in that study.

Tough to pinpoint the chicken and the egg: Did global warming cause the shift to more trees instead of grasslands, or did the change from grasslands to trees cause more global warming?

i'll never again hunt a woolly mammoth. save the planet!

I mean, doesn't this prove the futility of trying to revert to an agrarian society

tonight the temperature dropped to 55 degrees and I'm near the South, therefore global warming is a hoax

More Trees, Less Global Warming, Right? -- Not Exactly
A 150-year simulation of worldwide deforestation finds that tropical forests are carbon sinks and boreal forests contribute to warming

"'I'm not sure the slight amount of cooling is necessarily significant, but that removing all the forest produced little change' on temperature is, says study co-author Ken Caldeira, an ecologist at the Carnegie Institution of Washington's Department of Global Ecology in Stanford, Calif. 'I think what's interesting is this global cancellation was a product of very different responses at different latitudes.'"

Quote :

"Navin Ramankutty, an assistant professor of geography and Earth system sciences at McGill University in Montreal, says this study is the first to take a comprehensive look at the consequences of deforestation on the entire world. 'You can't just blindly go ahead and reforest and that will tackle climate change,' he says, pointing out a key finding in the study. 'If you think about conservation groups, they're all talking about planting trees. We should be protecting tress for other reasons.'"

Quote :

"'Too narrow a focus on global warming and a loss of the broader focus of protecting life on this planet can lead to perverse outcomes.'"
