How forests fight back against global warming with chemical warfare

A new study finds that the terpenes, isoprenes and other chemicals that trees release into the atmosphere help ameliorate the worst effects of global warming. Climate News Network has the story.

The warmer the weather, the greater the likelihood that gas emissions from plants would create conditions for the formation of clouds, which in turn would reflect more sunlight back into space, and thus help damp down global warming.

That is the good news. The not-so-good news is that these plant gas emissions won’t make a great deal of difference – on a global scale they might counter about 1 percent of global warming.

On a regional scale, however, the effect might be much greater: in heavily forested areas – Finland, Siberia and Canada, for instance – where human emissions of aerosols are anyway relatively slight, plant gas releases might counter as much as 30 percent of warming.

About Dave Bonta

I'm the author of several small, odd books, including Breakdown: Banjo Poems, Words on the Street: An Inaction Comic, and Odes to Tools, but my real work is at my literary blog Via Negativa. I'm the editor and publisher of Moving Poems, a webzine showcasing videopoetry and poetry film. And I've been a dedicated if somewhat unorthodox homebrewer for more than 20 years.
