MWP helped Inca Civilization Flourish

Full story: www.livinginperu.com

The last time global warming came to the Andes it produced the Inca Empire. A team of English and U.S. scientists has analyzed pollen, seeds and isotopes in core samples taken from the deep mud of a small lake not far from Machu Picchu and their report says that "the success of the Inca was underpinned by a period of warming that lasted more than than four centuries." The four centuries coincided directly with the rise of this startling, hyper-productive culture that at its zenith was bigger than the Ming Dynasty China and the Ottoman Empire, the two most powerful contemporaries of the Inca. "This period of increased temperatures," the scientists say, "allowed the Inca and their predecessors to expand, from AD 1150 onwards, their agricultural zones by moving up the mountains to build a massive system of terraces fed frequently by glacial water, as well as planting trees to reduce erosion and increase soil fertility. Core samples from glaciers and from the mud beneath lakes in the Andes, the Amazon and elsewhere have built up a history of the world's climate and the message is crystal clear. It is that changes have taken place in the past, during the six or seven thousand years of our agriculture-based civilizations, that are just as big as the ones we are facing from today's CO2 warming.

'For instance, the pollen in the cores says that there was maize being grown under the Incas around the lake at 3,300ms a.s.l. Until recently the upper level for maize around the Urubamba valley was 3,000-3,100ms. In the past few years the maize level has moved up and today there is maize being grown again above Marcacocha.

Alex's records show that hundreds of terraces were being built around the lake between 1100 and 1150 AD -"lots of mud followed by the heavy pollen of maize."

Enrique Mayer, at Yale, tells me that "the question of the expansion of maize together with the Inca state is now a proven archeological fact, notably in the Mantaro Valley (Tim Earle).]

Just more evidence for a GLOBAL MWP that was as warm or warmer than current temperatures. The same evidence of a global MWP has also come recently from Angkor Wat in Cambodia and even New Zealand and South Africa. That pretty much covers the Southern Hemisphere.

No longer can you alarmists say that the MWP was only a regional, European phenomena and retain any shred of credibility.

Global warming is making life easier at 4,000m above sea level.
The valleys and surrounding hills have formed the roof of the human world for at least three millennia, according to Alex Chepstow-Lusty's core samples. Nowhere else do millions of people live at or even near 4,000ms above sea level where it is cold, but getting warmer.

Today's warming is also following on a colder spell that started, the core samples say, not long after the arrival of the Spaniards in the 16th century.

For instance, the pollen in the cores says that there was maize being grown under the Incas around the lake at 3,300ms a.s.l. Until recently the upper level for maize around the Urubamba valley was 3,000-3,100ms. In the past few years the maize level has moved up and today there is maize being grown again above Marcacocha.

More correctly, it's evidence that current temperatures are at least as warm as "MWP" temperatures in that area.

Those of us who are not AGW denialists know how to read: we can tell that it really says "STOP GLOBAL WAR", but that the final letters are on a portion of the sign the camera did not capture due to the sign's curvature.

But hey, since you denialists are so confused by the difference between 'climate' and 'weather', and by the difference between "instantaneous, local" and 'average', I am not surprised that you were confused;)

Don't be silly. In the first place, it wouldn't make much sense for the sign to read "Stop Global War" at a climate change demonstration, particularly since the last world war ended in 1946.
In the second place, if you look at the picture you can see a bit of the next letter behind the corner of the blue sign.

And finally, why do you want to assume it says War instead of Warming? What's the point of your argument?

Not necessarily. He could have meant to say that AGW is War on the planet.

Still, I have to agree with you that 'warming' is a much more likely reading than 'war'. I can't believe I forgot that when making my own post on the topic above:(

Well, that's probably the best laugh I'll have today.

My guess is that Matty's somewhere around 50 years of age and still behaving like the high school brat he probably was in the 70s.
I wonder if he had a droopy (porn star) moustache like I did back then and flared trousers?
Or was he one of those geeks with his head stuck in a book all the time?
Whatever he was/is, I really feel sorry for him now, with his eyes glued to a computer monitor for so many hours each day, trying to save the world.

Oops, yes, I lost sight of the thread as it strayed off topic.

I can certainly vouch for this part:
"Also, you have John Treacy's book on Coporaque which is probably the most technically accessible to the argument that terraces are, like flower pots, expensive to maintain."
It has happened here where I'm living.
Within the last 100 years, many of the terraces at higher levels, that were once cultivated under grape, almond etc, by farm workers who had to walk everywhere, are now abandoned, although many are still producing crops of almond, while the grapes are now only grown at the lower levels, where gravity fed irrigation water is available.

It's quite understandable that the Incas may have had similar problems.

The only person who has made of fool of himself in this thread is you,'earthling'. You have made such a fool of yourself with your red herrings and innuendo, you prove you really do deserve the epithet 'dirtling' instead.
