ILST Ghenghis Khan reduced carbon foot print and slowed down global warming.
"It's a common misconception that the human impact on climate began with the large-scale burning of coal and oil in the industrial era," said lead researcher Julia Pongratz."Actually, humans started to influence the environment thousands of years ago by changing the vegetation cover of the Earth's landscapes when we cleared forests for agriculture,"
The Carnegie study measured the carbon impact of a number of historical events that involved a large number of deaths.Time periods also looked at included the Black Death in Europe, the fall of China's Ming Dynasty and the conquest of the Americas.All of these events share a widespread return of forests after a period of massive depopulation. But the bloody Mongol invasion immediately stood out for its longevity.And this is how Khan, who repeatedly wiped out entire settlements, was able to scrub more carbon from the atmosphere than any other despot.
