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.

Dynamics of Collapse
Posted by feww on January 28, 2008
The First Wave of the World’s Collapsing Cities
The following table lists the world’s cities that are likely to collapse completely or partially by or before 2012¹ in the first wave of collapse. The collapse would be caused by a combination of environmental catastrophes; failing infrastructure; food, water and fuel shortages; infectious disease; civil conflict. Following the first phase of collapse, massive waves of human migration from the affected areas create domino effect that cause the collapse of the remaining population centers shortly after.
