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.

‘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.’

The annual growth rings in trees are the most important witnesses over the past 1,000 to 2,000 years as they indicate how warm and cool past climate conditions were.

Researchers from Germany, Finland, Scotland, and Switzerland examined tree-ring density profiles in trees from Finnish Lapland. In this cold environment, trees often collapse into one of the numerous lakes, where they remain well preserved for thousands of years.

The density measurements correlate closely with the summer temperatures in this area on the edge of the Nordic taiga; the researchers were thus able to create a temperature reconstruction of unprecedented quality.

The reconstruction provides a high-resolution representation of temperature patterns in the Roman and Medieval Warm periods, but also shows the cold phases that occurred during the Migration Period and the later Little Ice Age.
In addition to the cold and warm phases, the new climate curve also exhibits a phenomenon that was not expected in this form.

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. </span>

Yeah, but they used 2,150 years of data while our resident climatologists have te last 30 days backing them up.

Well thats a narrow field.

This is such a credible finding that they somehow forgot to link to the peer-reviewed publication in which it appeared!

And they used a geologist for their expert, apparently!

Yes, highly credible, I say!

Actually, of course, if there is any truth to this at all, any science to this at all, it relates to the climate in... Finland.

Who says the Finland climate is a good examplar for the world climate? The researchers?

It's the same issue with the Medieval Warming period (whatever they call it), which has been know about for some time. There is no showing that what it appears to indicate was the case in Europe was anything world wide.

Suggestion: if you didn't already know it, the Daily Mail is a right-wing trash tabloid, which is not a reliable source on anything, probably. Especially on climate matters, which it has consistently distorted over many years now.

And if you think about it, if this were entirely true, it doesn't help the side of the AGW deniers at all.

For if the secular trend has been cooling, the current heating is all the more abrupt and inexplicable under those trends (as they mention, the earth-sun distance is getting longer (typical gravitation effect, same with the earth-moon distance), AND we've been in a very deep solar minimum condition, and yet the temps are still rising?

In stock market terms, the price has regained (and thus confirmed) its peak, and that means the upward trend is still alive (as this year's first six months are the hottest in the historical record, everywhere in the world).

So we've matched 2008, although THAT year was both a solar maximum year and an El Nino (warming) year, and this is neither.

Am i missing something here?????????????????????????????????????????????? ?????????????????????

Theze finnish tree rings, if they show that the world haz been cooling more than we thort, and if they show that scientists hav been wrong, then that wrong iz in a direktion that makes modern manmade warming even bigger and more worrying.

Or am i missing something here?????????????????????????????????????????????? ?????????????????????

God bless them ... at least someone promotes actual science amidst the Eurogoremon cult.

If this is actual science, it has yet to be seen in a scientific forum, based on this article's obvious failure to cite the study or any journal it appears in.

It's well known that even actual published scientific papers are badly misrepresented by general media publications, who often claim in headlines implications that are not part of the paper.

How much worse is a yellow journalist partisan paper at misrepresenting actual scientific papers, still less, random findings that are not robust enough to be published somewhere in a credible scientific journal?

Face it, their extensive history of the reporting you applaud is entirely crap lying, if not simply incompetence.
