Who would've thought deforestation had an upside?

Satellite flyovers of newly cleared land in the Amazon have uncovered a vanished civilization that could rival the Incans or Aztecs in sophistication.

Researchers found mysterious geometric trenches and other earthworks carved into the landscape as early as a decade ago, but satellites have paved the way for the discovery of over 200 giant structures.

Writing in the journal Antiquity, the researchers say the the formations stretch for some 250 kilometers (155 miles) across the upper Amazon basin east of the Andes mountains and appear to be of a similar style throughout, suggesting one vast, united civilization that could have totaled some 60,000 inhabitants.

Researchers also found stone tools, bits of ceramics, and other artifacts buried in mounds along the trenches. So far, the uncovered areas date to between 200 and 1283 A.D., but the team thinks they've seen "no more than a tenth" of the true extent of this archeological wonder. More from an article which appeared Tuesday in the Guardian:

"These revelations are exploding our perceptions of what the Americas really looked liked before the arrival of Christopher Columbus," said David Grann, author of "The Lost City of Z," a book about an attempt in the 1920s to find signs of Amazonian civilizations. "The discoveries are challenging long-held assumptions about the Amazon as a Hobbesian place where only small primitive tribes could ever have existed, and about the limits the environment placed on the rise of early civilisations."

ElDorado2 They are also vindicating, said Grann, Percy Fawcett, the explorer who partly inspired Conan Doyle's book "The Lost World."

Fawcett led an expedition to find the City of Z but the party vanished, bequeathing a mystery.

Many scientists saw the jungle as too harsh to sustain anything but small nomadic tribes. Now it seems the conquistadores who spoke of "cities that glistened in white" were telling the truth.

They, however, probably also introduced the diseases that wiped out the native people, leaving the jungle to claim – and hide – all traces of their civilization.

There is no upside. The planet is unquestionably dying with the Arctic melting, the destruction of coral reefs and the average temperature climbing at rates that demand a complete stop to deforestation releasing CO2.

I strongly recommend that for the preservation of all mankind that we consider methods of conservation quickly.

No CO2 increase in last 150 years

The trend since 1850 has been "essentially zero"

31 Dec 09 - New research finds that the airborne fraction of carbon dioxide has not increased either during the past 150 years or during the most recent five decades, contrary to some recent studies. See entire article" www.sciencedaily.com/releases/2009/12/091230184221.htm

In contradiction to some recent studies, he finds that the airborne fraction of carbon dioxide has not increased either during the past 150 years or during the most recent five decades.

All he says is that anthropogenic contributions have little contributions based upon his research. The FACT remains: CO2 emissions are CLIMBING at a rapid rate over the past 150 years.

Based on what evidence from a legitimate and untainted source?

Are you saying that CO2 is not climbing in concentrations around the world? Well, it certainly is. Look over any urban city AROUND the world in modern western cultures ... and do you note: automobile exteriors (over a few years) look old and fragmented?

It is because of the CO2 concentrations in that same local proximity. The CO2 concentrations in combination with both sulfur and chloride in the atmosphere create acids; creating acid rain, covering the automobile exteriors rotting away the otherwise beautiful appearance of a fine assemblyline modern machine.

Just as the same in the oceans and the seas around the world destroying the balances of nature there.

I will concede the point that possibly CO2 levels have shown a modest increase.

However, as farmfriend points out there is no evidence that it is necessarily a bad thing. The Earth has historically had much higher levels of CO2 than are currently in the atmosphere.

We're still here.

Imagine that.

We're still here.

And so are the corals!

the coral is threatened more by crown of thorn starfish than CO2.
