Quote: “The climate change at [10,500 years ago] which turned most of the [3.8 million square mile] large Sahara into a savannah-type environment happened within a few hundred years only, certainly within less than 500 years,” said study team member Stefan Kroepelin of the University of Cologne in Germany.
That climate change existed 10,500 to 7,300 years ago before the Sahara turned into a desert, had nothing to do with people (or cars). Climate change comes from the Sun!
No, that was all due to SUVs.
They are so evil that they can cause climate change even prior to their invention.
