Life and human population thrive with the resources from the Sahara a lot more than with what they naturally get in the Antarctic. The Sahara itself used to support a lot of life it just needed more water, not less heat. --- Around 12,500 BC, the amount of dust in the cores in the Bølling/ Allerød phase suddenly plummets and shows a period of much wetter conditions in the Sahara, indicating a Dansgaard-Oeschger (DO) event (a sudden warming followed by a slower cooling of the climate). The moister Saharan conditions had begun about 12,500 BC, with the extension of the ITCZ northward in the northern hemisphere summer, bringing moist wet conditions and a savanna climate to the Sahara, which (apart from a short dry spell associated with the Younger Dryas) peaked during the Holocene thermal maximum climatic phase at 4000 BC when mid-latitude temperatures seem to have been between 2 and 3 degrees warmer than in the recent past. en.wikipedia.org

Hi bentway; Re: "That's why the Sahara desert, formerly a rich agricultural region, has such a high population, rich wildlife and great agricultural production, right Fubbie?" Okay so you're a complete moron who believes everything liberal and can't understand basic physics. But I'll put a corrective note so that the readers who aren't stupid can understand your confusion (and explain the truth to their friends). The reason the Sahara is not a rich agricultural region is not because it's hot, but instead because it's dry. What's lacking that you need to grow plants is water. And rainfall does tend to reduce temperatures somewhat. Now rainfall comes from the sky, but before it gets up there it has to evaporate from somewhere. And the most usual place it evaporates at is the oceans. Furthermore, as any fool who has boiled water on a stove can attest, warmer air will evaporate more water from the oceans. And that evaporation returns to the land as life-giving rain. In short, the desert regions on the planet expand during ice ages and contract during interglacials. And so there's every reason to believe that the overall size of the world's deserts will decrease if the planet warms. -- Carl P.S. What I've written above is simple physics. It's very straightforward and the lefties will deny that it's a fact even though it's a well known fact of geology. So here's a link where you can verify this simple fact of physics (i.e. no faulty climate simulations needed to understand the fact that warmth means more rain and less desert, in addition to being an obvious result of physics, it's also demonstrated in the geological record): From the University of California at San Diego's "Earth Guide": Ice Age Climate Cycles Other Information from Ice Cores Besides temperature, many other types of information can be extracted from ice cores by analyzing wind-blown dust, volcanic matter, and trapped air. The dust content of glacial ice in Greenland is more than ten times greater than that in ice made during warm intervals. This suggests that glacial periods tended to have dry weather and strong winds, in the regions south of the ice shields. (Cold air holds much less water vapor than warm, so this is not surprising.) During a cold dust storm in the plains, the thick matted hair of mammoth must have been a real life-saver. earthguide.ucsd.edu The loess deposits of the central US, which now form the best farm land on this planet, were deposited as dry dust by ice age winds. Warm weather is good for growing food. Ice ages are the danger to humanity, not hotter temperatures. If you don't know what loess is or where it's found or what it's good for, the wikipedia article may be of interest: en.wikipedia.org
