New Research Cool on Global Warming

Newsflash: that "hocky-stick" purporting to demonstrate rapidly-rising temperatures is a hoax.

This record of Northern Hemisphere temperature variation in the last 1,000 years shows a recent warming trend apparently linked to human activities.

New work in the journal Geophysical Research Letters questions its validity, challenging the way it was originally put together.

Other scientists say the work simply highlights a technical issue.

...

The authors say that when they took [the original hockey-stick analysis' biased methodology] into account, the results in the 1998 paper did not achieve statistical significance.

"This means their model is not qualified for projecting temperatures back more than 500 years," Dr McKitrick added.

...
However, even those scientists who agree with evidence for recent, strong anthropogenic warming have reservations about models such as the hockey stick.

According to Professor John Waterhouse, of Anglia Polytechnic University in Cambridge, UK, the so-called Medieval Warm Period (AD 800 to 1400) and the Little Ice Age (AD 1600-1850) do not show up.

"Most climate researchers expected them to be there," he told the BBC News website.

Um, yeah. That's what bugs me the most. We know for a fact that the Northern Hemisphere, at least, was so warm for a period that grains became incredibly cheap, they grew grapes for wine in dreary, cold England, and that even Greenland was warm enough for primative agriculture to sustain a large colony.

Yet the hockey-stick says: No such warming ever occurred.

Except, of course, that it did.
