Water Emergency in Calif

As most of the croplands in the Central U.S. is submerged under floodwater, the heart of California’s farming area is feeling the heat. Gov. Schwarzenegger who proclaimed last week a drought in California, declared yesterday a state of emergency in nine counties in Central Valley.

Tipping Point

A confirmation of tipping point is presented in the following report by James Hansen, NASA climatologist:

Excerpts from Hansen’s report:

  • We are at the tipping point because the climate state includes large, ready positive feedbacks provided by the Arctic sea ice, the West Antarctic ice sheet, and much of Greenland’s ice.
  • Our home planet is dangerously near a tipping point at which human-made greenhouse gases reach a level where major climate changes can proceed mostly under their own momentum. Warming will shift climatic zones by intensifying the hydrologic cycle, affecting freshwater availability and human health.
