New Study Thoroughly Debunks Global Warming, Will Media Notice?

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:
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.
