MIT researchers think they have solved a bit of a mystery regarding Sahara dust, but if they're right it means the Sahara Desert has already come and gone 3 – 5 times since humans walked the Earth. The Sahara is the largest desert on Earth, and this would be the largest and longest drought "ever" on the planet (as far as we know).
This would rather redefine the whole idea of "climate change" — 3.5 million square miles of Green Sahara turns into Dust-bowl Sahara — and it's all thanks to sunlight. The drought doesn't just last 7 years, but more like 7,000. And it's happening over 9 million square kilometers, an area larger than Australia. The major climate models leaned towards the monsoonal cycle, rather than the longer ice age one. So this theory may have resolved one of the 495 contradictions in climate models. Or not. But the bigger message here is that the sun causes climate change and on a massive scale.

The Sahara is the largest dust bowl in the world, dumping 10 million dump trucks of dust across North Africa and the Atlantic Ocean. The dust can end up as far [...]
