Rings in fossilised pine trees have proven that the world was much warmer than previously thought - and the earth has been slowly COOLING for 2,000 years.
Measurements stretching back to 138BC prove that the Earth is slowly cooling due to changes in the distance between the Earth and the sun.
The finding may force scientists to rethink current theories of the impact of global warming.
It is the first time that researchers have been able to accurately measure trends in global temperature over the last two millennia.
Over that time, the world has been getting cooler - and previous estimates, used as the basis for current climate science, are wrong.
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 finding was based on semi-fossilised tree rings found in Finnish lapland.
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.

Any thoughts, Al?
Global warming was occurring in Roman times, with the root cause being that Rome was burning.
Similar reasons for today’s globull warming...
They must’ve had some really “polluting” engines on those chariots of theirs.
Horse poop?
From Steve Jones’ “Darwin’s Ghost,” a modern rewrite of Darwin’s “Origin,” we have: “A trillion comets orbit the sun. The gravel that surrounds them appears, should it hit our atmosphere, as a shower of meteors. The Earth gains a ton in weight every hour from their dust.”
I have heard that very statement from some AGW people.
Big ‘ol bookmark!
It HAD to be warmer back then. That’s why everyone was wearing togas!..................
This is a newspapert article that does not cite the original scientific study- a little odd not being able to access the data, methodology etc. Also what is JGU. I assume a University but which one? This could be a set up. Tree ring data is what the “hockey stick” graphic was all about.
Trees don’t represent temperature and half a year doesn’t represent an annual record.
Junk science is junk science, whether its them or us.
I was a little bit afraid of that. Always the threat of lots of folks jumping on the bandwagon just to be discredited. Thanks for the heads up.
