World Was Warmer in Roman and Medieval Times

[Odessa78]

Rings in fossilised pine trees have proven that the world was much warmer than previously thought - and the earth has been slowly COOLING for 2,000 years.
Measurements stretching back to 138BC prove that the Earth is slowly cooling due to changes in the distance between the Earth and the sun.
The finding may force scientists to rethink current theories of the impact of global warming.

It is the first time that researchers have been able to accurately measure trends in global temperature over the last two millennia.
Over that time, the world has been getting cooler - and previous estimates, used as the basis for current climate science, are wrong.

Their findings demonstrate that this trend involves a cooling of -0.3°C per millennium due to gradual changes to the position of the sun and an increase in the distance between the Earth and the sun.


Professor Dr. Jan Esper's group at the Institute of Geography at JGU used tree-ring density measurements from sub-fossil pine trees originating from Finnish Lapland to produce a reconstruction reaching back to 138 BC.

Can you imagine how cold it would be right now if not for the fossil fuels being used over the last 100 years?

we could all have been dead by now.

OMG! GLOBAL COOLING! We have to do something NOW before it's too late!

Thats an easy fix, let your SUV idle.

Wasn't that period know as the climatic optimum? Named because the warmer temps increased food production and led us from the dark ages into the renaissance period.

However, the study actually does none of the above. "Our study doesn't go against anthropogenic global warming in any way," said Robert Wilson, a paleoclimatologist at the University of St. Andrews in Scotland and a co-author of the study, which appeared July 8 in the journal Nature Climate Change. The tree rings do help fill in a piece of Earth's complicated climate puzzle, he said. However, it is climate change skeptics who seem to have misconstrued the bigger picture.

Ouch! July in US was hottest ever in history books

"The average temperature for the Lower 48 last month was 77.6 degrees. That breaks the old record from July 1936, during the Dust Bowl, by two-tenths of a degree. Records go back to 1895."

"Last month also was 3.3 degrees warmer than the 20th century average for July."

"The first seven months of 2012 were the warmest on record for the nation. And August 2011 through July this year was the warmest 12-month period on record."

"Climate scientist Jake Crouch of the National Climatic Data Center in Asheville, N.C., said the U.S. is getting a double whammy of both localized heat and drought along with effects of global warming."
