The Truth About "Carbon Offsetting"

"...New research found that trees bathed in extra carbon dioxide grew more tissue, but did not necessarily store significant extra quantities of carbon. Instead, the tree's capacity to absorb the gas depended on water and nutrient levels.

The news will come as a blow to the carbon-offsetting industry, which has expanded rapidly as individuals and companies try to atone for their carbon dioxide emissions by paying companies to plant trees for them.

What we're finding is that extra carbon very quickly goes back into the atmosphere if there are low nutrients and water available.

"And we are not going to be able to increase the capacity of forests to hold carbon, because we couldn't fertilise such large areas or provide sufficient water. It would cause such pollution that the consequence would be much worse than carbon dioxide enrichment in the atmosphere." (source)

I guess Al Gore, Leonardo and the Rolling Stones are going to have to find a new way to justify their excesses while they preach conservation ot the masses...
