The Guardian says white men caused the Little Ice Age by killing Native Americans after 1492 – and they say they will not be quiet about the “climate crisis.”

Interesting theory, given that rapid cooling began about 200 years before Columbus arrived in America.
The Little Ice Age started 40 years before Columbus showed up.
Through analyzing tree rings, the Arizona researchers have concluded that they have yet to see the first fruits of the so-called greenhouse effect, the warming of the earth that many say will result from humanity’s release of excessive heat-trapping gases like carbon dioxide and methane into the atmosphere.
But Donald A. Graybill, who studies bristlecone pine trees growing at high elevations in the White Mountains of eastern California, has evidence that the carbon released into the air by the burning of fossil fuels like coal and gasoline is sharply stimulating the growth of bristlecones, both by serving as fertilizer and by making the elderly wonders more efficient in their use of water.
Lisa J. Graumlich, who examines the ring patterns of foxtail pine trees and western junipers in the Sierra Nevada, has compiled a detailed record of the year-to-year variation in temperature and precipitation over the last thousand years.
She has seen in the North American trees the feathery but unmistakable signatures of the Medieval Warm Period, a era from 1100 to 1375 A.D. when, according to European writers of the time and other sources, the climate was so balmy that wine grapes flourished in Britain and the Vikings farmed the now-frozen expanse of Greenland; and the Little Ice Age, a stretch of abnormally frigid weather lasting roughly from 1450 to 1850.
A Crucial Question “We can now see that these were global climate phenomena, not regional temperature variations,” she said. “The question is, how did we get those warmer temperatures during pre-industrial times, and what can we learn from those conditions about what is going on today?”

There is no indication humans had any impact on CO2 levels before about 1830.
The Guardian article is the work of a sociopath, but it does reflect the mindset of their editors – who believe genocide and depopulation is necessary to cool the planet.
