climate change causes madness
The once-green Sahara turned to desert over thousands of years rather than in an abrupt shift as previously believed, according to a study on Thursday that may help understanding of future climate changes.
And there are now signs of a tiny shift back towards greener conditions in parts of the Sahara, apparently because of global warming, said the lead author of the report about the desert’s history published in the journal Science.
Kropelin told Reuters that improved understanding of the formation of the Sahara might help climate modellers improve forecasts of what is in store from global warming, blamed by the U.N. Climate Panel on human emissions of greenhouse gases.The panel says that some areas will be more vulnerable to drought, others to more storms or floods.
