Joe Nocera has guts. He has also learned quickly a lot about climate change politics and science. He writes:
“The deliberate use of technology to manipulate the environment — usually in the context of fighting climate change — is called geoengineering. One method is carbon capture, traditionally conceived as a process that sucks up carbon from the air and buries it in the ground. A second is called solar radiation management, which uses techniques like shooting sulfate particles into the stratosphere in order to reflect or divert solar radiation back into space. This very effect was illustrated after the volcanic eruption of Mount Pinatubo in the Philippines in 1991. Spewing 20 million tons of sulfur dioxide in the air, the volcano caused global temperatures to fall, temporarily, by about 0.5 degrees Celsius, according to Wagner and Weitzman.
Somewhat to my surprise, a good portion of Wagner’s and Weitzman’s book is devoted to the subject of geoengineering, especially solar radiation management, which they describe as relatively inexpensive and technologically feasible, with a serious bang for the buck. The reason I was surprised is that the authors have solid environmental credentials — Weitzman is an environmental economist at Harvard, and Wagner is a senior economist at the Environmental Defense Fund — and many environmental groups object to the very idea of geoengineering. They even object to research into the subject, viewing the desire to manipulate nature as immoral. Ben Schreiber of Friends of the Earth, an advocacy group, recently described discussions about geoengineering as a “dangerous distraction.” ”
