Fire Earth

Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Tipping Point: Here and Now!

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. James Hansen

Tipping Point: PERSPECTIVE OF A CLIMATOLOGIST [PDF]
by JAMES HANSEN

An Excerpt from Hansen’s report:
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.

[James Hansen is director of the National Aeronautics and Space Administration Goddard Institute for Space Studies and an Adjunct Professor of Earth and Environmental Sciences at Columbia University’s Earth Institute.]

The ice in the Arctic is much younger than normal, with vast regions now covered by first-year ice and much less area covered by multiyear ice.
