Climate: While CBS touts a "groundbreaking" government report linking extreme weather and climate change, German researchers find 2,000 years of cooling and warmer temps in medieval times and the Roman era.
This summer's heat wave has given the global warmongers new hope in conning the hot and the restless into believing the whole thing is due to that SUV parked in your driveway and that coal-fired plant down the street.
Not so fast, say German researchers who documented a two millennia cooling trend. Both the Roman legions and Crusaders marched in warmer climes.
On Wednesday's CBS This Morning, CBS News correspondent Wyatt Andrews breathlessly intoned that a recent study from the National Oceanic and Atmospheric Administration (NOAA) had established "the first-ever statistical connection between extreme weather and man-made climate change" and that the study "found that man-made heat made the Texas drought roughly 20 times more likely."
Well, you know the adage about lies, damned lies and statistic. We have documented how researchers at Britain's Climate Research Unit manipulated data to "hide the decline" in global temperatures that other data, such as from satellite observations, had indicated.
The U.N's Intergovernmental Panel on Climate Change relied on anecdotes from suspect sources to produce carefully edited reports warning about such things as the Himalayan glaciers soon disappearing.
Wyatt's report featured Tom Karl, chief of the climate office at NOAA, talking about shifts in the La Nina and El Nino ocean currents, which have contributed to our hot summer. But they are naturally occurring phenomena predating the Industrial Revolution.
Wyatt's conclusion was that "NOAA scientists, meanwhile, are not saying that climate change causes any one specific drought, like the one in Illinois. They are saying the science is good enough now, they can lay odds on the connection."
Laying odds? The science is "good enough"?
Facts, as Ronald Reagan said, are stubborn things. German researchers at Johannes Gutenberg University used tree-ring density measurements from sub-fossil pine trees in Finnish Lapland to answer how the Romans were able to grow grapes in northern England.
Unlike the manipulated Siberian tree ring data used by researcher Michael Mann at the University of Pennsylvania to support his case for global warming, the German researchers found the Finnish tree data, which let them reconstruct global climate back to 138 BC, showed something quite different, such as a slight cooling trend that has lasted 2,000 years.
In general the scientists found a slow cooling of 0.6 degrees centigrade over 2,000 years, which they attributed to changes in the Earth's orbit — not CO2.
Lead author Professor Jan Esper of Johannes Gutenberg University in Mainz said: "We found that previous estimates of historical temperatures during the Roman era and the Middle Ages were too low."
The study showed Britain 2,000 years ago had a lengthy period of hotter summers than today, including 21 AD to 50 AD, when temps were one degree centigrade warmer than today. That might explain the togas.
"This figure we calculated may not seem particularly significant, however it is not negligible when compared to global warming, which up to now has been less than 1 degree centigrade," Esper said.
He also noted that their "findings are also significant with regard to climate policy, as they will influence the way today's climate changes are seen in context of historical warm periods."
We hope so. A Congressional Research Service (CRS) report that showed that from fiscal years 2008 through 2012 the federal government spent $68.4 billion to fight the phantom known as anthropogenic global warming (AGW) or man-induced climate change.
In its name, the war on fossil fuels has decimated our economy, stunting growth and increasing joblessness.
So next time you hear earth is doomed, just think of toga-clad Romans eating grapes in Northern England.
