Sorry, Al: Tree Planting May Speed Warming

Posted Apr 10, 07 9:06 AM CDT in Science & Health 

(Newser) – Planting trees to offset your carbon footprint not only won't slow global warming, it may worsen its effects, a new study claims. Trees growing outside a small band of tropical zones don't cut the amount of greenhouse gases in the atmosphere by enough to offset the heat their foliage traps, says atmospheric scientist Govindasamy Bala in the Guardian.

The preferred penance of affluent carbon-fuel guzzlers may actually be counter-productive, Bala says. By the end of the century, forested areas in the mid and high latitudes could be about five degrees warmer than those with fewer trees because dark foliage absorbs sunlight and heat.

    Climate Change Deniers Still Impeding Progress Scientists thought they'd convinced the world it was getting warmer, but a powerful, flush campaign of cynics is still successfully sowing doubt, Newsweek reports—and hobbling efforts to stave off disaster. From its humble beginnings ridiculing any warming, the "denial machine" has picked up funding from big oil and developed a more nuanced strategy: make Americans believe climate change is still an open question.
