Earth warned on 'tipping points'

Date : 26th August 2004, Source : BBC Link to News Story

The world has barely begun to recognise the danger of setting off rapid and irreversible changes in some crucial natural systems, a scientist says. Professor John Schellnhuber said 12 "hotspots" had been identified so far, areas which acted like massive regulators of the Earth's environment. One example of a hotspot was the North Atlantic current, the ocean circulation pattern responsible for bringing warmer air to northern Europe, the collapse of which could lead to a very large regional climate shift. Others were the West Antarctic ice sheet, the Sahara desert, the forests of the Amazon basin, and the Asian monsoon system.
