New Study Thoroughly Debunks Global Warming

While much of the nation has recently suffered under a massive heatwave, warming alarmists and the willingly complicit global warming-obsessed media have depicted the high temperatures (and even forest fires) as evidence of Nobel laureate Al Gore's favorite money-making scam, a new study published in the journal Nature Sunday thoroughly 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's the reader-friendly explanation of the study's results from the website of Johannes Gutenberg University Mainz (H/t - NewsBusters):

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 degrees Celsius 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 degree Celsius. 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 on 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.

[...] 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 degree Celsius 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.

This simple graph from The Register demonstrates what's really happened in the past 2,000 years. It thoroughly debunks any claim that temperatures on the planet today are in any way historic or unprecedented:

The graph clearly illustrates exactly what many climate realists have been saying for years.

Take the time to read the entire Register piece here. As The Register goes on to make clear ... according to the scientists' new paper, published in hefty climate journal Nature Climate Change, the cooling effect of orbital shifting on the climate has been up to four times as powerful as anthropogenic (human-caused) warming pressures.

In other words, the effect of man on climate is proven to be other than what the alarmists continue to claim - essentially none ... zippo ... nada ... not an iota.

Meanwhile, what we can expect from the media on this story is surely nothing more than ... crickets, crickets, crickets ... and then more crickets.
