New Study Thoroughly Debunks Global Warming, Will Media Notice?

From NewsBusters.org, By Noel Sheppard, July 11, 2012 – In the past several weeks as much of the nation suffered under a massive  heatwave, global warming-obsessed media depicted the high temperatures as  evidence of Nobel laureate Al Gore’s favorite money-making scam.

A new study  published in the journal Nature Sunday completely debunks all previous claims  that temperatures in recent decades are in any way historic demonstrating  instead that things were much hotter on this planet during Roman times:

Here, we present new evidence based on maximum latewood  density data from northern Scandinavia, indicating that this cooling trend was  stronger (−0.31 °C per 1,000 years, ±0.03 °C) than previously reported, and  demonstrate that this signature is missing in published tree-ring proxy records.  The long-term trend now revealed in maximum latewood density data is in line  with coupled general circulation models indicating albedo-driven feedback  mechanisms and substantial summer cooling over the past two millennia in  northern boreal and Arctic latitudes. These findings, together with the missing  orbital signature in published dendrochronological records, suggest that  large-scale near-surface air-temperature reconstructionsrelying on tree-ring  data may underestimate pre-instrumental temperatures including warmth during  Medieval and Roman times.

The website of Johannes Gutenberg University Mainz published  a more reader-friendly explanation of the study Monday:

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. In so doing, the researchers have been able for the first time to  precisely demonstrate that the long-term trend over the past two millennia has  been towards climatic cooling. “We found that previous estimates of historical  temperatures during the Roman era and the Middle Ages were too low,” says Esper.  “Such 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.”

For the first time, researchers have now been able to use  the data derived from tree-rings to precisely calculate a much longer-term  cooling trend that has been playing out over the past 2,000 years. 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.

“This figure we calculated may not seem particularly  significant,” says Esper. “However, it is also not negligible when compared to  global warming, which up to now has been less than 1°C. Our results suggest that  the large-scale climate reconstruction shown by the Intergovernmental Panel on  Climate Change (IPCC) likely underestimate this long-term cooling trend over the  past few millennia.”

The UK Register observed  Tuesday:

Americans sweltering in the recent record-breaking  heatwave may not believe it – but it seems that our ancestors suffered through  much hotter summers in times gone by, several of them within the last 2,000  years.

A new study measuring temperatures over the past two  millennia has concluded that in fact the temperatures seen in the last decade  are far from being the hottest in history.

Here’s a nice little graph to demonstrate what’s really happened in the past  2,000 years:

This thoroughly debunks the claim that temperatures on the planet today are  in any way historic or unprecedented.

The Register continued:

In the IPCC view, the planet was cooler during Roman  times and the medieval warm spell. Overall the temperature is headed up – perhaps wildly up, according to the famous/infamous “hockey stick” graph.

The new study indicates that that’s quite wrong, with the  current warming less serious than the Romans and others since have seen – and  the overall trend actually down by a noticeable 0.3°C per millennium, which the  scientists believe is probably down to gradual long-term shifts in the position  of the Sun and the Earth’s path around it.

Just as many climate realists have been saying for years.

The only question remaining is whether America’s global warming-obsessed  media will pay any attention to this new information.

Stay tuned.
