Depopulation of Americas may have cooled climate
MINNEAPOLIS — By sailing to the New World, Christopher Columbus and the other explorers who followed may have set off a chain of events that cooled Europe’s climate for centuries.
The European conquest of the Americas decimated the people living there, leaving large areas of cleared land untended. Trees that filled in this territory pulled billions of tons of carbon dioxide from the atmosphere, diminishing the heat-trapping capacity of the atmosphere and cooling climate, says Richard Nevle, a geochemist at Stanford University.
“We have a massive reforestation event that’s sequestering carbon … coincident with the European arrival,” says Nevle, who described the consequences of this change October 11 at the Geological Society of America annual meeting.
Tying together many different lines of evidence, Nevle estimated how much carbon all those new trees would have consumed. He says it was enough to account for most or all of the sudden drop in atmospheric carbon dioxide recorded in Antarctic ice during the 16th and 17th centuries. This depletion of a key greenhouse gas, in turn, may have kicked off Europe’s so-called Little Ice Age, centuries of cooler temperatures that followed the Middle Ages.

Oh no! Killer trees!
The cooling started before the "official" Little Ice Age. Around 1200. Pack ice started to grow in 1250. Around 1300 summers were cooling in Europe. 1315 was a rainy period and the times of great famines. All this stuff happened before Columbus.
Now if Erik the Red caused the diseases to spread all across the native tribes, there might be an argument, but a lot of this happened before Columbus. In fact some of the little ice age effects and politics from it and the famines (especially the religious fights with England) may have been a reason for the Columbus voyages in the first place.
There also was a large number of Mt Pinatubo+ level of major volcanic eruptions during that period. That causes global cooling.
Maybe we can talk the m-c-g-w believers to take one for the team? I'll chip in for the required kool-aid.
He was overexposed to cannabis - - - at least.....
Ah yes, the Jesuits.
The creators of liberation theology .......
Notice how they totally whitewashed the significant role that the Keebler Elves played in Columbus’ evil scheme.
old joke.
too old.
Gosh. I thought the Little Ice Age had something to do with the Maunder Minimum and the disappearing sunspots. Silly me.
Columbus - The First Environmentalist.
This is all it takes to get on a straight site called “Science News”?
Really?
If I submit that Japanese Beetle caused World War II, would they publish it?
This isn’t even pseudo-science; it’s delusional.
BUGS: What's the matter, Chris?
COLUMBUS: The ice-ah age, she-ah no-ah mah fault!
I stand corrected.
His bibliographies are quite impressive. I would call him a reporter covering science, history and archeology.
What kind of rag would publish this
delusional Marxist propaganda ?
This clearly shows that tenure is an environmental hazard.
Whenever a person becomes tenured, he/she is free to make irresponsible statements that are given too much weight, affect policy, and lead to ill-thought-out, destabilizing environmental decisions.
Abolish tenure...for the environment.
