As little as 6,000 years ago, the vast Sahara Desert was covered in grassland that received plenty of rainfall, but shifts in the world's weather patterns abruptly transformed the vegetated region into some of the driest land on Earth. Now a researcher is trying to uncover the clues responsible for this enormous climate transformation -- and the findings could lead to better rainfall predictions worldwide.
Who would have ever thought that the Sahara Desert was covered in grassland at some point? Definitely not me. It's amazing to see the affect of weather shifts across the world. Today, the Sahara is one of the driest places on earth which is why this story is so fascinating.
"Tropical rain belts are tied to what happens elsewhere in the world through the Hadley circulation, but it won't predict changes elsewhere directly, as the chain of events is very complex. But it is a step toward that goal."
These finding are making it easier to predict how much weather has changed in various regions of the world. These shifts in weather can be caused by many different factors and it's interesting to see where the shifts occurred and in what way.
