Warming hits ‚tipping point‘

A vast expanse of western Sibera is undergoing an unprecedented thaw that could dramatically increase the rate of global warming, climate scientists warn today.

[…] It is a scenario climate scientists have feared since first identifying „tipping points“ – delicate thresholds where a slight rise in the Earth’s temperature can cause a dramatic change in the environment that itself triggers a far greater increase in global temperatures.

[…] Climate scientists yesterday reacted with alarm to the finding, and warned that predictions of future global temperatures would have to be revised upwards.

„When you start messing around with these natural systems, you can end up in situations where it’s unstoppable. There are no brakes you can apply,“ said David Viner, a senior scientist at the Climatic Research Unit at the University of East Anglia.
