“They’ve been telling us for 100 years that human deforestation of Africa was turning it into a desert. And the trees are taking over?”
It was during the ice ages that most of Africa was desert, because all the water was frozen in glaciers.
Of the water on Earth, a small percentage was locked up in glaciers. Although all that ice (and whatever caused it), certainly changed the climate.
Its curious as to what caused the Holocene Wet Phase(from about 7500–7000 BC to about 3500–3000 BC), that turned the Sahara green. And just as curious as to what ended it.
Wrong. I was there at the time and Africa was green then.
