Dedicated to all, who believe in the Global Warming hoax and Climate Change religion! Yes climate changes all the time for many, many millennia and many times in dramatic ways long before the spurious and phony term anthropogenic was coined!
Global Warming aka Climate Change will go down as one of the greatest scams in human history! Like in the Medieval Ages, too many people still believe in fairy tales!
At least parts of the Arabian peninsula were green and had lakes several times over the past 400,000 years.
"Ten years ago, no dated archaeological sites more than 10,000 years old had been recorded in the three million square kilometres of the Arabian Peninsula. ..."
"Here we report a series of dated palaeolake sequences, associated with stone tool assemblages and vertebrate fossils, from the Khall Amayshan 4 and Jubbah basins in the Nefud Desert. These findings, including the oldest dated hominin occupations in Arabia, reveal at least five hominin expansions into the Arabian interior, coinciding with brief ‘green’ windows of reduced aridity approximately 400, 300, 200, 130–75 and 55 thousand years ago. Each occupation phase is characterized by a distinct form of material culture, indicating colonization by diverse hominin groups, and a lack of long-term Southwest Asian population continuity."
"... The results bolster the idea that the periodic greening of this typically harsh desert played a pivotal role in humans’ dispersals out of Africa—and provide the best evidence yet that different groups of humans pulsed out of the continent through the Sinai Peninsula ...
But past excavations and paleoclimate models have revealed that over the past half-million years, brief periods of wetter, warmer conditions dumped seasonal rainfall over the region, turning its low basins into lakes and its ditches into rivers. In short order, the harsh desert became a lush grassland—a “green Arabia”—only to wither back to sand when arid weather inevitably returned. ..."
