Geological evidence of recent warm or warmer Arctic.

An excerpt:

"Hakan Grudd, of Stockholm University's Department of Physical Geography and Quaternary Geology, compared both tree ring width and maximum density, to construct the most accurate data yet seen for the region. He found a sharp warming trend since the year 1900. However, over the entire period, several such warming events were seen with temperatures in at least four periods (AD 750, 1000, 1400, and 1750) all equally warm or warmer than at present.

Most surprising of all, he noted, when taken as a whole temperatures in the Arctic have actually declined 0.3 degrees over the past 1,000 years. As Grudd himself says, temperatures at present are "not especially warm."

Here's the link to the story. It links to the published white paper with all of the technical information.

At the same time, realclimate.org doesn't understand why there tends to be more skeptics within the geologists camp.

The reason is obvious... Geologists are finding hard evidence that disputes a fair amount of what the IPCC/AGW crowd is saying.
