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.

I strongly recommend you get some help.

CO2 is not warming the planet. Deforestation in the Amazon is only bad because of the native plants there that are fonud no where else in the world. More CO2 in the atmosphere equals better crops and more trees everywhere! That's right, CO2 is NOT a pollutant.

So, let's say you are ill and go to the local hospital to fetch some professional care. You need to breathe, correct? Do they place a mask over your face to breathe in oxygen or carbon dioxide?

I think Ricky would prefer the CO2.

Sarcasm, correct?

Sarcasm, correct?

With Ricky being Ricky, I really think he WOULD choose the CO2. He's not that bright when it comes to science and stuff...

Our individual and mutual health is in fact the most important asset about ourselves. It seems to me that some people don't know the difference between simple issues that affect not just their own personal daily livelihood(s) but the rest of the world around themselves.

The politics are deep. But to deny science and common sense seems a bit strange to me.

I'm not absolutely certain that the world really IS in danger of global warming at this point, but it would be wise to reduce emissions regardless, since it's not JUST the CO2 we need to be worried about, it's the spectrum of other REALLY nasty pollutants that are truly poisoning us directly and indirecty via our food and water.

Of course, if the global warming pundits ARE correct, and the ocean temperatures ARE rising, then we DO need to be concerned with CO2 levels.

I haven't been keeping up with the news, but do you know whether or not there is any actual evidence of ocean temperatures rising?

This is from NASA so pro AGW site:

Short-Term Ocean Cooling Suggests Global Warming 'Speed Bump'

The average temperature of the water near the top of the Earth's oceans has significantly cooled since 2003. New research suggests global warming trends are not always steady in their effects on ocean temperatures.

NPR, pro AGW site:

The Mystery of Global Warming's Missing Heat

by Richard Harris

Some 3,000 scientific robots that are plying the ocean have sent home a puzzling message. These diving instruments suggest that the oceans have not warmed up at all over the past four or five years. That could mean global warming has taken a breather. Or it could mean scientists aren't quite understanding what their robots are telling them.

NYT:

Ocean Cooling and Global Warming

By ANDREW C. REVKIN

The video loop above shows satellite readings of sea surface height, an indirect measure of heating (because of the way warmer water expands).

Along with two co-authors, Josh Willis, a climate scientist and ocean expert at NASA’s Jet Propulsion Laboratory, found that warming of the seas — as measured by a network of deep-diving “Argo” buoys — essentially stopped over the last four years.
