Researchers from the Lawrence Livermore National Laboratory reported in the "Proceedings of the National Academy of Sciences" (April 17) that while tropical forests exert a cooling influence on global climate, forests in northern regions exert a warming influence — and it’s not just a trivial climatic effect.
Based on the researchers’ computer modeling, forests above 20 degrees latitude in the Northern Hemisphere — that is, north of the line of latitude running through Southern Mexico, Saharan Africa, central India and the southernmost Chinese island of Hainan — will warm surface temperatures in those regions by an estimated 10 degrees Fahrenheit by the year 2100.
It would appear that the efforts to save the habitat of the spotted owl by shutting down the logging industry in the Northwest U.S. has significantly impacted the warming of the planet. ΛΕΟΝΙΔΑΣ suggests that we stand by for the data outlining the negative impact on the planet of growing crops to produce ethanol. Oops that's already happened.
