Figure 4 in B.A. Black et al.: This image shows annually averaged temperature anomalies in excess of 3°C for the first year after the Campanian Ignimbrite (CI) eruption compared with spatial distribution of hominin sites with radiocarbon ages close to that of the eruption.
No it was caused by climate change. Just ask a liberal. They can provide all kinds if maps and charts and probably even throw in a few photographs for good measure..
Nope. It was Transfats.
Neanderthals are alive and well as part of the liberal voting block.
That's as far as I got.
" The last glacial period was preceded by 1000 years of the coldest temperatures of the Late Pleistocene, apparently caused by the eruption of the Mount Toba volcano. The six year long volcanic winter and 1000-year-long instant Ice Age that followed Mount Toba's eruption may have decimated Modern Man's entire population. Genetic evidence suggests that Human population size fell to about 10,000 adults between 50 and 100 thousand years ago. The survivors from this global catastrophy would have found refuge in isolated tropical pockets, mainly in Equatorial Africa. Populations living in Europe and northern China would have been completely eliminated by the reduction of the summer temperatures by as much as 12 degrees centigrade."
The Toba survivor numbers have been increased substancially since this article was written. Even so, almost everyone died.
A volcanic eruption in the East Indies in 1815 caused a "year without a summer" in 1816 in Europe and North America. Tens of thousands of Europeans died of starvation because the crops failed.
