Plan to turn farms into forest worries Obama official

"That's one of the realities of cap-and-trade legislation. The biggest
bang for your buck for carbon credits is planting trees," she said.

That's an issue with the structure of the credits and regulations, not the
science.

The problem with trees is that they only soak up carbon until the forrest
reaches maturity. Then they are carbon neutral. If you can go in and cut
the trees down before they get old, the carbon removed from the
environment is equal to the carbon hauled out of the forrest on logging
trucks.

But people become emotionally attached to trees and try to keep them around
long after they've stopped soaking up CO2.
Which for many types of trees could be in excess of 200 years.
Granted, they get less efficient as the years go by after a certain
point.
