Skip to comments.Columbus' Arrival Linked to Carbon Dioxide Drop

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.

Scientifically illiterate. CO2 conc. FOLLOWS temperature changes. Doesn’t drive them.
Is there any evil that can’t be traced back to white men?
What kind of rag publishes this Marxist twaddle ??
What a pantload.
Oh... I thought it was the plot to a science fiction book.
The “science” in that article was so abysmal that the author(s) qualify for a primary position on the Obamaloon Clown Show of Cretin/Felons.
Gads, would I have loved to had them in a good numerical analysis course - so they could receive their well deserved Fs and then proceed to get a marshmallow major and become congresscritters. If they got Ds in those worthless majors, they could also become vice-president.
So there was no possible cause and effect between the Permian extinction event, and rising CO2 levels, from the methane that had erupted from the bottom of the sea?
Earth to lib arts majors, yup, it’s “have had,’ not “had”.
So sue me.
The European conquest of the Americas decimated the people living there,
Exactly what decimation occurred? A few thousand Indians? Did the Indians have corporate farms stretching across the entire country? Did virtually every new arrival from Europe not farm the land after clearing large tracts for said purpose?
The logic of this hypothesis is ridiculous.
Orders of magnitude higher CO2 than what the “researchers” were discussing.
Maybe one result of this whole AGW farce will be to identify for future inclusion or exclusion from serious consideration two classes of "scientists", those who are legitimate and thus willing and able to look at the actual empirical evidence and those who are no more scientists than the Vatican jury who placed Galileo under house arrest. Same applies to the "scientific" authors and their publications, or in this case propaganda organs.
It is startling, though, to see the death grip this theory has on so many people who should know better, and disgusting since their fanatic loyalty is so clearly tied to the almighty coin.
I am awed. Who know Columbus was so powerful! Wow!
Little known fact: Columbus never set foot in America. He made it to Haiti and the Bahamas and that’s it. John Cabot was an Italian explorer who landed in what is now known as North America with a commission on behalf of England. We, at the time not wanting to give Britain credit for anything, decided to rally around the Spaniard, Columbus. The only reason it’s not Washington DC (District of Caboto, rather than Columbia) is simply, petty spite. Columbus went on to commit a genocide on the Native Americans that would’ve made Hitler blush.

According to the article:
“......By the end of the 15th century, between 40 million and 100 million people are thought to have been living in the Americas. Many of them burned trees to make room for crops, leaving behind charcoal deposits that have been found in the soils of Mexico, Nicaragua and other countries.
About 500 years ago, this charcoal accumulation plummeted as the people themselves disappeared. Smallpox, diphtheria and other diseases from Europe ultimately wiped out as much as 90 percent of the indigenous population.
Trees returned, reforesting an area at least the size of California, Nevle estimated. This new growth could have soaked up between 2 billion and 17 billion metric tons of carbon dioxide from the air.
Ice cores from Antarctica contain air bubbles that show a drop in carbon dioxide around this time. These bubbles suggest that levels of the greenhouse gas decreased by 6 to 10 parts per million between 1525 and the early 1600s.....”

This article is even worse than that. It was posted a few days ago. The claims made in the article are ludicrous. It isn’t science. Not the least bit.
What better fit to their hate the West ideology than the White men killing the Red men causes a global catastrophe.
