European Colonizers Killed So Many Indigenous People The Planet Cooled Down

I wonder why this was never mentioned in our history books.

Maybe because someone thought it was bad enough America is already known for instituting, managing, and expanding the longest and most brutal forms of human slavery the planet has ever seen.

When you add in how white people killed so many indigenous melanated people that the planet cooled down, there’s no way to see America as “great” ever again. That’s probably why they left this part out.

According to a report on

“European contact brought with it not only war and famine, but also diseases like smallpox that decimated local populations. In fact, a February 2019 study published in the journal Quarternary Science Reviews shows that those deaths occurred on such a large scale that they led to a “Little Ice Age”: an era of global cooling between the 16th and mid-19th century.

Researchers from University College London found that, after the rapid population decline, large swaths of vegetation and farmland were abandoned. The trees and flora that repopulated that unmanaged farmland started absorbing more carbon dioxide and keeping it locked in the soil, removing so much greenhouse gas from the atmosphere that the planet’s average temperature dropped by 0.15 degrees Celsius.”

  • Following Christopher Columbus’ arrival in North America in 1492, violence and disease killed 90% of the indigenous population — nearly 55 million people — according to a study published this year.
  • Diseases like smallpox, measles, and influenza, which colonizers brought to the Americas, were responsible for many millions of deaths.
  • The new research also reveals that following this rapid population decline and the subsequent reduction in land use, there was a global cooling trend.
