European colonizers killed so many Native Americans that it changed the global climate, researchers say
When Europeans arrived in the Americas, they caused so much death and disease that it changed the global climate, a new study finds.
European settlers killed 56 million indigenous people over about 100 years in South, Central and North America, causing large swaths of farmland to be abandoned and reforested, researchers at University College London, or UCL, estimate. The increase in trees and vegetation across an area the size of France resulted in a massive decrease in carbon dioxide (CO2) in the atmosphere, according to the study.
Carbon levels changed enough to cool the Earth by 1610, researchers found. Columbus arrived in 1492,

The increase in trees and vegetation across an area the size of France resulted in a massive decrease in carbon dioxide (CO2) in the atmosphere, according to the study. Carbon levels changed enough to cool the Earth by 1610, researchers found. Columbus arrived in 1492, "CO2 and climate had been relatively stable until this point," said UCL Geography Professor Mark Maslin, one of the study's co-authors. "So, this is the first major change we see in the Earth's greenhouse gases."
1600. The Little Ice Age is a period between about 1300 and 1870 during which Europe and North America were subjected to much colder winters than during the 20th century. The period can be divided in two phases, the first beginning around 1300 and continuing until the late 1400s.

This is proof that CNN is now hiring "journalist" directly from high school.
