Planting Trees In Tropics...



...like Guatemala would help offset carbon emissions.

So say A.C. Thompson & Duane Moles (among others) in "Don't Bet on Offsets," in HOT POLITICS on PBS:

"Forestry projects are controversial among global warming analysts, because it takes years for saplings to mature and start sucking up sizable quantities of carbon dioxide--plus, when the trees die and decompose, they release that CO2 back into the air. Research shows that planting trees in places with a moderate climate is less effective than sowing trees in warmer zones."
