| - | The Younger Dryas event was a period of extreme cooling theoretically caused by an abrupt change in the North Atlantic thermohaline current, brought about by the Lockhart phase of Lake Agassiz flooding down the Hudson; this event was probably brought about by a cometary impact. Recent evidence indicates the cooling occurred within the span of mere months as the thermohaline current shut down. The time period also coincides with 1500y solar cycles, which have been implicated in repeating cooling events. Other evidence points towards this being the start of the Anthropocene, due to men wiping out the huge methane producers of the age, although the cometary impact evidence has begun edging this out. Global de-cooling begins to take place after this event, leading to deluges that heralded many of the great flood stories. Monsoon changes in the Sahara made it a lush plainsland with gigantic lakes, and at least two groups of peoples (the Kiffians first, and the Tenerians at least a thousand years later). | + | The Younger Dryas event was a period of extreme cooling theoretically caused by an abrupt change in the North Atlantic thermohaline current, brought about by the Lockhart phase of Lake Agassiz flooding down the Hudson; this event was probably brought about by an impact event.
