As behaviorally modern Homo sapiens spread out of Africa more than 50 000 years ago, their advanced hunter - gatherer societies helped to cause the extinction of more than half of Earth's mammalian megafauna, yielding trophic

My impression from looking at the conference material is that it was indeed more or less what you would expect four years
on from the 2001 IPCC report, with two very large exceptions: The potential collapse of the West Antarctic Ice Sheet (= 5 meter sea level rise) and ocean acidification (= partial ocean
ecosystem collapse with a subsequent
cascade of potential side
effects that practically defy description).
