Cool! 2

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.

This comes from the Mail Online:

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.

May do? Must do!

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.’

What will the warmists, Big Green, the UN, and the Left in general have to say about this? We’re listening, all agog to know.

    Another one of my “friends” on Facebook has bit the dust. I showed her the Daily Mail article, and she said she already knows what Conservatives say, and then said I lost my mind when I said I don’t believe in Global Warming. It really is like a religion!

    Yes, it looks like we could use a little global warming to counteract this cooling trend!  Since we can’t move the earth back closer to the sun, it looks like maybe a little MANMADE warming might be just the ticket!
