By sailing to the New World, Christopher Columbus and other explorers who followed him may have set off a chain of events that cooled Europes climate.
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, Stanford University geochemist Richard Nevle reported October 11 at the Geological Society of America annual meeting. Such carbon dioxide removal could have diminished the heat-trapping capacity of the atmosphere and cooled the climate, Nevil and his colleagues have previously reported.
We have a massive reforestation event thats sequestering carbon coincident with the European arrival, said Nevle.
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. Such a depletion of a key greenhouse gas may have helped augment Europes so-called Little Ice Age, centuries of cooler temperatures that followed the Middle Ages, Nevle's team has argued.
By the end of the 15th century, between 40 million and 100 million people are thought to have been living in the Americas.

Bring back the Italian guy pretending to an Indian, he was good for a laugh.
HA! When the first Italians arrived here, they were considered, and called, niggers by some Irish.
You are right. I would think that it would take the killing of millions of Native Americans to cause such a reforestation and the colonists made great efforts to clear land themselves. I am confused.
Since science has been recording atmospheric CO2 and temperature, changes in CO2 lag behind changes in temperature. Reconstructed CO2 and temperature record going back thousands of years show the same pattern. A few handfuls of catastrophic events in the past billion years have seen CO2 concentrations surging so fast that it overwhelmed the systems that maintain a relatively stable climate. These rare exceptions tell us that the moderating systems can be overwhelmed but so what?
Changes in CO2 lag changes in temperature except when extremely rare catastrophic events release overwhelming amounts of CO2. Drinking water is healthy except in extremely rare cases where people drink overwhelming amounts. My analogy is brilliant.
There are absolutely no societies built on hunting/gathering, as most of the North American Indian tribes were, that can generate enough food to support forty million or more people. North of the Rio Grande the Indian population probably was in the area of two to five million at most. In central America the Aztecs had cities and the populations there were probably a lot larger. But nowhere near forty million. Leftist historians (or hysterians) at work again.

There is evidence that South America was extensively farmed. An early Spanish explorer who went from the Andes to the Atlantic down the Amazon reported seeing large cities. No one believed him. New evidence seems to show he wasn’t lying.
But Methane eruptions should not be ignored just because they are rare. They are extremely dangerous and should be looked into much more then the man made global warming hoax
Where does that data, and those conclusions come from?
(I mean, sez who?)

Should take you about 15 minutes. Go to it tiger.
Brilliant. The folks behind the “CO2 Science”

Saying pretty much what you did.

You find a web site that (I’ll take your word) supports my point and you spin it to make it look like it weakens my point. You may be weak on the science but you’ve obviously been paying attention to how to politic the subject.
As to the web site you linked to, I know nothing about it. And I don’t speculate on things I know nothing about.
But that’s just me.
Credit where credit is due on taking what I’ve written and re-phrasing and re-arranging it to make your point. (That straw man is lying all over both sides of the street, in tatters.)
But you’re the one who said, “search” and then back-pedaled at 200 mph when the source I found suggested the origin for (at least some of the science) for your claims about CO2 could be oil company funded.
Them’s the facts, Jack.
(In other words, don’t piss and moan when you offer “Bing” as a source for your research, and what pops up (on Google) provides a less than completely solid or substantial support for what you’ve been pulling out of your butt.)
LOL. You don’t like the source you found, do another search.
I didn’t have to look. The topic popped up at me from the TeeVee:
“...The Daily Show Notes Irony of Koch-Funded Study Affirming Global Warming is Real
Last night’s entire first segment of The Daily Show focused on the recent study funded by the Koch Brothers that confirmed (again) that climate change is indeed a reality - an ironic twist given the Kochtopus’ track record of fueling the climate change denial echo chamber with upwards of $55 million.
As described in an earlier piece on DeSmogBlog, “The [Berkeley Earth Surface Temperature (BEST)] paper, an effort to confirm or debunk whether the urban heat island (UHI) effect was skewing climate records, has affirmed - again - that global temperature records are accurate and worrisome....”

There’s the problem! You get your information from the Daily Show.
Did you know that you are watching comedy? I guess not.
Powerline has been doing a wonderful job rebutting all the leftist crap being thrown at the Kochs.
climate change is indeed a reality
Obviously climate changes. Tell me who denies that?
Seriously — no irony, sarcasm, or edginess implied at all — isn’t the whole point supposed to be to remain objective, and dismiss the bias, wherever it’s coming from?
I’ll admit that I do have a personal take on this discussion.
.....In the late 70’s, a very good friend, a mining engineer, went to Mexico. As a former official representing the U.N. delegation for the Greek Colonel’s military regime, he needed a new job. To make a long story short, he wandered through the jungle as the point man for a consortium of partners and found a very, very old silver & gold mining site. According to the original, Spanish colonial (17th century) map of the area, the location he’d found was a valley almost a mile deep. But the topography was more or less flat. The valley — roughly an oval, miles wide by many miles long — had been completely filled in with “tailings,” the rock left over after all the valuable bits had been taken away.
I always wondered how many slaves had had to work, digging how many hours every day, every week, every month, for how many decades and centuries (the opening of the mine had pre-dated the Spanish Armada and it probably continued to 1815), to fill in that nearly mile-deep ‘valley.’
So, reading about the “CO2 drop linked to Columbus’ Arrival” that did tend to reinforce my own presupposition that there may have been many more locals on hand than people realized. Which seemed to be confirmed by the Antarctic ice core samples.
As far as the relative benefit or harm, though, of CO2 in the atmosphere, no matter who (or what) is responsible for pumping it out, the most recent data (sponsored by the coal industry, of all people) would seem to suggest there is cause for concern, based on the **rate of change,** and perhaps prior history. If one can make the leap of logic that there some degree of human causation had a hand in kicking off the “Little Ice Age.”
