h/t Dr. Willie Soon; 6000 years ago during the Holocene Climatic Optimum the Sahara desert was covered in lakes and vegetation. All this went away when the world cooled. Some of the poorest people in the world, descendants of survivors of the great drying, struggle to survive by scratching a living in the Sahel, the marginal land on the southern edge of the Sahara.
Africa climate change report reveals heat rising north and south, Sahel getting wetter

“In recent months we have seen devastating floods, an invasion of desert locusts and now face the looming spectre of drought because of a La Niña event. The human and economic toll has been aggravated by the COVID-19 pandemic,” WMO Secretary-General Petteri Taalas said in a statement.
Africa has been warming progressively since the start of the last century, and in the next five years, northern and southern Africa are set to get drier and hotter, while the Sahel region of Western Africa will get wetter, WMO’s Regional Strategic Office Director, Filipe Lucio, told a press conference.
“Overall, Africa needs to take action. Action is needed today in terms of adaptation, but also is needed tomorrow in terms of mitigation”, Lucio said.
The agricultural sector is key to building climate resistance, since it is the dominant employer and it relies on the use of water and energy – both heavily implicated in climate change, he said.
Northern and southern areas under threat of aridity and desertification would benefit from reforestation, which helps to prevent water runoff and creates vegetation which supports the hydrological cycle.

Carbon obsessed organisations like the United Nations only see the negative side of global warming.
Imagine the benefits to Africa and Arabia, and other arid equatorial regions, if global warming restored the ancient Monsoons, which failed 6000 years ago after the end of the Holocene Optimum? Northern Africa and Arabia could once again be like the Garden of Eden.
I suspect we shall run out of fossil fuel long before we release enough CO2 to make the climate that benign. Perhaps when recoverable fossil fuel runs out, our descendants will maintain elevated atmospheric CO2 levels by using nuclear powered furnaces to roast limestone and other CO2 rich minerals, to alleviate the suffering of our planet’s CO2 starved plants. They will most certainly laugh at the public climate change follies of our times, just as we laugh at the irrational concerns of our ancestors.
