Only 6,000 years ago the world was warmer and the Sahara was lush green and wet

New Study Finds The Early-Mid Holocene Sahara Had Lakes With Depths Of ‘At Least 300 Meters’

During the hottest part of the Holocene, for thousands of years, there were deep lakes filled with water in the middle of the Sahara Desert. From 9,500 years ago to 6,000 years ago the monsoons rained on the Sahara, freshwater plankton frolicked in the lakes, and greenery grew far and wide. The wetter conditions made it possible for “widespread human occupation and the development of agriculture across North Africa”. Amazingly, that last quote comes from Kuper and Kropelin fully seventeen years ago. Strangely the UN experts don’t mention very often that in the warmer world not that long ago, the hyperarid Sahara desert was rich, green and filled with water? We wouldn’t want people to start wondering if climate change might mean Chad and Libya could be nicer places for Africans to live? Instead we’re told that global warming will turn into our whole world into the Saharan desert, only to find out that in a warmer world […]

The ecologist who says we *need* huge herds of cows and sheep to stop desertification?

Can cows shrink deserts?

Allan Savoury is a farmer from Zimbabwe who used to believe that livestock were destroying the land. He still believes the CO2 scary narrative, but even despite all that, he’s an ecologist who now argues we need large herds moving nomadically to stop desertification.

Years ago he was one of the scientists advising the Zimbabwe government to get rid of lifestock to save the land. In a great moment of ecology they even shot 14,000 elephants for land restoration which didn’t work. That was the saddest blunder of my life, he says. And when he went to the US he found national parks were desertifying too even though they had not had livestock on them. “Clearly we didn’t understand what was driving desertification”. He now claims that the soil of grasslands ends up encrusted with algae, which leads to water runoff and evaporation “and that is the cancer that leads to desertification”.

I’m sure cows don’t change the climate either way, but this sure flies in the face of the idea that livestock create deserts and eating meat destroys the land.

Desertification cancelled: Climate Change won’t make the deserts grow

After a thousand headlines told us Climate Change would make deserts grow, a new study suggests it won’t. It’s a finding that shocks no one who knew that climate models have no predictive skill with rainfall, and that a warmer world means higher global precipitation. Plus there’s the awkward clue that for the last forty years the arid regions of the world have been getting greener instead of more deserty.

Looks a bit different?

The top map (below) shows the deserts expanding — but that’s the old predictions which are based only on “atmospheric data” like temperature and rainfall. The bottom map is the new work which uses soil and vegetation data too. Red means growing deserts. Blue means shrinking.

Remember, all contradictory conclusions are based on expert opinions using worlds best practice and done by Nobel-Prize-winning people. Shame about all the farmers and investors making decisions based on junk models.

Deserts were expanding until experts got a better model.


The new study is based on modeling too so it is still wrong, but less useless than previous studies.

The hugely different forecasts show how vaporously thin the past doom and gloom was, and how so many […]

The Sahara may flip from desert to grass every 20,000 years. Blame The Sun.

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).

UPDATED: Commenter Javier points out these drying cycles were known years ago. (See below)

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.
