Two reports in Science, the American Association for the Advancement of Science (AAAS) journal, got considerable media coverage on Feb. 8-9 with results in both showing that expanding biocrops for energy will greatly increase the soil emission of greenhouse gases (GHGs) mainly carbon dioxide from the exposing of buried plant debris. The UN report released in Spring 2007 and prepared by the Scientific Expert Group (SEG) under the aegis of Sigma Xi said that “Even if human emissions could be instantaneously stopped, the world would not escape further climate change.” The Winter 2006 issue of AAAS Matters called for carbon dioxide sequestering. So we are going the wrong way with bioenergy thinking sponsored by BP at Berkeley and need to get a program that will actually remove some of the 35 percent overload of carbon dioxide mentioned in my Nov. 30, 2007, commentary.
