Save the Planet, Chop down a Tree

Trees contribute to global warming (at least in the higher latitudes)

The authors discovered that a global replacement of current vegetation by trees would lead to a global warming of 2.4 degrees Fahrenheit. Global replacement with grassland led to cooling of about 0.7°F.

The researchers also found that planting trees between 30 and 50 degrees latitude worldwide saw the global mean surface air temperature increase by 0.7°F. Regional warming in North America and Eurasia was as high as 8°F. In earlier studies, planting trees in the boreal forest regions (found mostly in the upper half of the Northern Hemisphere) caused a warming of surface temperatures.

Lest you think these scientist weren't still in favor of dismantling the economy like all good Greens should want

“But in terms of climate change, we should focus our efforts on things that can really make a difference, like energy efficiency and developing new sources of clean energy.”
