Global warming can be reversed by killing people.

Mass deaths resulting from America’s colonisation caused the atmosphere to cool down.
Experts believe the influx of Europeans and the outbreak of war in the 15th Century sparked an environmental shift which literally lowered the local temperature.
This is because swathes of agricultural land became abandoned and overgrown following the deaths of tens of millions of indigenous people.
As a result, trees and foliage absorbed increased levels of carbon dioxide from the atmosphere, prompting what’s casually referred to as a ‘little Ice Age’.
The Great Dying of the Indigenous Peoples of the Americas led to the abandonment of enough cleared land that the resulting terrestrial carbon uptake had a detectable impact on both atmospheric CO₂ and global surface air temperatures,’ says study author Alexander Koch, University College London.
His team studied population data from 1492 onward to see the impact of conflict and disease.
Settlers and soldiers carried European diseases like smallpox, measles, typhoid and the flu, which ravaged communities.
As a consequence of these fatalities, land the size of France was subsequently abandoned, lowering the concentration of CO₂ in the atmosphere by 7-10ppm (7-10 molecules of CO₂ in every one million molecules in the air).
‘To put that in the modern context – we basically burn (fossil fuels) and produce about 3ppm per year. So, we’re talking a large amount of carbon that’s being sucked out of the atmosphere,’ added co-author Prof Mark Maslin.
‘There is a marked cooling around that time (1500s/1600s) which is called the Little Ice Age, and what’s interesting is that we can see natural processes giving a little bit of cooling, but actually to get the full cooling – double the natural processes – you have to have this genocide-generated drop in CO₂.’
