A 2,300-year climate record University of Pittsburgh researchers recovered from an Andes Mountains lake reveals that as temperatures in the Northern Hemisphere rise, the planet's densely populated tropical regions will most likely experience severe water shortages as the crucial summer monsoons become drier. The Pitt team found that equatorial regions of South America already are receiving less rainfall than at any point in the past millennium. [snip]
Paired with these sources, the sediment record illustrated that rainfall during the South American summer monsoon has dropped sharply since 1900 -- exhibiting the greatest shift in precipitation since around 300 BCE -- while the Northern Hemisphere has experienced warmer temperatures.

The sediment core shows regular fluctuations in rainfall from 300 BCE to 900 CE, with notably heavy precipitation around 550. Beginning in 900, however, a severe drought set in for the next three centuries, with the driest period falling between 1000 and 1040. This period correlates with the well-known demise of regional Native American populations, Abbott explained, including the Tiwanaku and Wari that inhabited present-day Boliva, Chile, and Peru.
After 1300, monsoons increasingly drenched the South American tropics. The wettest period of the past 2,300 years lasted from roughly 1500 to the 1750s during the time span known as the Little Ice Age, a period of cooler global temperatures. Around 1820, a dry cycle crept in briefly, but quickly gave way to a wet phase before the rain began waning again in 1900. By July 2007, when the sediment core was collected, there had been a steep, steady increase in dry conditions to a high point not surpassed since 1000.

Ya, ya, ya. We’ve heard all this before.
Parts of Texas are having a record drought as our middle states flood. SC: Catastrophism ping?
Ping.
Nonsense! It’s all Bush’s fault. Oh, and SUV’s and evil oil and coal plants! So there!
And my question to them is as always: what the hell then was causing the problem X number of [years, decades, centuries, milleniums] ago if it’s man-made ‘climate change’ today?
Junk Science Alert!
Doesn't the southern hemisphere get hurricanes, too? Didn't the climate nuts predict more hurricanes because of glo-bull warming (not that we really got any more than usual)? I'm sure they'll find a way to "explain" this away, like the way they explain more cold and snowfall in the north ("That's global warming!! It's gotta' get colder before it gets warmer!!").
It’s always trending warmer, or cooler. It’s always trending wetter or more arid. The universal conclusion in all these studies is that the climate naturally changes.
Exactly, Bingo.
And, none -absolutely- none of them will tell you what the right ‘climate/temperature/environment’ should be except one that has no humans in it. They should be eradicated.
It’s thunder and lightning here in the Ohio Valley, and where’s Obama during all this calamity?
CE/BCE is code to identify the left wing bias of the authors of this piece. I’ll give it as much credibility as the hadley data
They were discussing a movie where London sinks beneath the sea due to global warming and they said “people have to take action today to stop this fantasy from becoming a reality tomorrow”.
I told my wife if I were writing a book on dumb statements that would have to be on page one. Then I corrected myself and said I would have to fit it into the foreword.
It would definitely be on the dustcover.
The ‘static’, ‘perfect’, environment of (most of) the woefully uneducated green-movement followers has never existed. It’s a delusion pure and simple. I love the outdoors. I respect the environment as much, if not more than, anyone I have ever met. I also accept that it used to be different and will be different in the future. They use it to attack their fellow human beings.
Exactly.
We feel the drought along the Mississippi River. Part of Louisiana hit by Katrina may in for a different kind of hit soon. At least people in LA are used to carrying flood Ins, My preioums are paid up thank the Lord!!! We will see what happens in the next few days how we will make out.
Only now are Cheby sales resuming and fingers are crossed!
If this is true, it’s fortunate that temperatures aren’t actually rising.
