New Study Thoroughly Debunks Global Warming, Will Media Notice?

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." [...]

Nice straw man. The only thing this "debunks" is the idea that contemporary temperatures are way beyond what humans have faced throughout history.

If the study is correct it shows that there has been a general cooling trend (about 0.3 degrees per year) over the past 2000 years.

Chop off the data that includes the increased amounts of human fossil fuel use (1850 to Present) and the cooling trend would be steeper.

So without us burning fossil fuels the Earth would be cooling more than it is today?

This study supports the case for Anthropogenic Global Warming.
