Canary in a coalmine or tipping points?

WorldChanging: Another World Is Here: Twelve Tipping Points: "What's most troubling is the manner in which such disruptions would very often trigger positive-feedback loops -- environmental changes which would in turn serve to accelerate the effects of global warming."



Useful introductory summary of two fo the tipping points from John Schellnhuber's development of twelve tipping points where small environmental effects could have big positive feedback effects which would accelerate climate changes. One is the greening of the Sahara but while this sounds good there are interesting benefits that ride on the Sahara being a desert and they would be lost. The other one summarised here is the effect on and of the monsoon. Interesting reading, and then you realise what it would mean and it becomes more than interesting.
