The study of ancient pollen, spores and aquatic organisms in sediments in Lake Yoa in northern Chad showed the region gradually shifted from savannah 6,000 years ago towards the arid conditions that took over about 2,700 years ago.
The findings, about one of the biggest environmental shifts of the past 10,000 years, challenge past belief based on evidence in marine sediments that a far quicker change created the world's biggest hot desert.
So, its apparent that one of the world's largest fuckkkin (with respect to location for Piccclefucks benefit) deserts is NOT the product of men driving pickup trucks in Texas or evil Amerwikans.
Fuckin politicians, socialists and enviro pimps and thier lies to usurp power and money. Algore should be sued for fraud and public panic mongering. Or shot in the head by mvscals.
