Global Warming Is Irreversible, Study Says

February 14, 2009 • Climate Change & Mitigation, News

Thanks to Steve Kurtz for this article.

Bruce Sundquist responded to the article two days ago (“World of Wasted Time” by Wayne Roberts) with the following comment: “I became aware some time ago that the usual methods for fighting global warming like energy conservation, sequestering in pressurized tanks of CO2, nuclear power etc. would no longer work. But two alternatives would still work – sequestering in forest biomass and sequestering of carbon in tropical cropland soils (the terra preta strategy). These two alternatives have the ability to extract greenhouse gasses from the atmosphere and therefore could halt global warming, and reverse it and cool the earth. The forest biomass alternative comes with an astronomical price tag and four serious risk factors that pretty well insure failure of that option. The terra preta alternative has plenty of sink capacity, and could pull greenhouse gasses out of the atmosphere fast enough to halt and reverse global warming, and at a low (if any) cost and minimal risk.” Bruce’s comments are equally applicable to the item below.

I have previously distributed Bruce’s article on terra preta. If you would like to see it, view it at

Global Warming Is Irreversible, Study Says

Climate change is essentially irreversible, according to a sobering new scientific study

As carbon dioxide emissions continue to rise, the world will experience more and more long-term environmental disruption. The damage will persist even when, and if, emissions are brought under control, says study author Susan Solomon, who is among the world’s top climate scientists.
