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.

In the absence of other evidence it might make sense, but the reduced solar activity at the time probably had far more impact.
The don’t call it Italian Ice for nothing.
thanks!!!!
That works!!!
the GW crowd says more stupid things all the time. me I am just a lowly auditor at a medicare health plan, and I know BS when I see it
It must have been some incredibly fine weed. LOL!!
Laughable, of course. Did Columbus and his crew fart all at the same time to get those ships moving or what? /s
I believe we could stand some quotes around that "science"...
Hmmm...Maybe he should collaborate on paper with that meathead commie in Congress who claimed that slave ships changed the whole ecological environment of the southern Atlantic ocean...

“atmospheric carbon dioxide...a key greenhouse gas”
The core idea of global warming theory is that if 3/10,000 of our atmosphere is CO2, we’re going to skip happily through sustainable meadows with unicorns, and if it’s 4/10,000 the world is going to be wrecked. It doesn’t matter how many scientists say what, that is never going to make even the tiniest bit of sense. (plagiarized)
I pinged SunkenCiv first thing, but I guess he didn't notice, or thought it unworthy of a ping.
I know; I saw that, and was joking that I got a reply in before he pinged me to an article he was pinged to for once.
Except, of course, that the depopulation of America occurred more than 100 years before Columbus landed in America.
Yes, well you see less population means less eating and less eating means less farting and less farting means less methane gas and less methane gas means less global warming.
Ipso facto we will all die if we don’t pass legislation IMMEDIATELY to outlaw farting. We must heavily regulate the eating of any gas producing foods to the extent possible.
BAN THE FART!!!
Rubbish. The little ice age was almost over by 1492. It has been blamed for the hundred years war and the black death.
LOL
They’re kidding, right? Every estimate that I’ve seen suggests that pre-Columbian North America was pretty thinly populated. Sure there were some areas in Central & South America that sported urban civilizations, but even there...
