Global wind-shift caused Earth’s last ice age to end

June 26, 2010
Washington, DC: A global shift in winds is what led to the end of Earth’s last ice age— an event that ushered in a warmer climate and the birth of human civilization.
It is believed that, in the geological blink of an eye, ice sheets in the northern hemisphere began to collapse and warming spread quickly to the south.
Most scientists say that the trigger, at least initially, was an orbital shift that caused more sunlight to fall across Earth’s northern half.
But they could not explain how the south dealt with the shift so fast.
And now a team of researchers looked for an answer towards a global shift in winds and proposed a chain of events that began with the melting of the large northern hemisphere ice sheets about 20,000 years ago.
The melting ice sheets reconfigured the planet’s wind belts, pushing warm air and seawater south, and pulling carbon dioxide from the deep ocean into the atmosphere, allowing the planet to heat even further.
Their hypothesis makes use of climate data preserved in cave formations, polar ice cores and deep-sea sediments to describe how Earth finally thawed out.
“This paper pulls together several recent studies to explain how warming triggered in the north moves to the south, ending an ice age,” said study co-author Bob Anderson, a geochemist at Columbia University’s Lamont-Doherty Earth Observatory.

Global Warming Hoax Weekly Round-Up, Jun. 25th 2010
The Daily Bayonet, June 24, 2010
Al Gore morphs into El Grope and continues his rapid descent into PR hell. Warmist hippies draw up an enemies list, David Suzuki drops the F bomb in a cafe and a Beatle is concerned with ‘climate warming’.
Part One: Al Gore & Friends
Al Gore is in the news again. Last week it was revealed that the Goreacle had been porking his movie producer, this week an Inconvenient Tryst is with a masseuse who claims that Al tried to get a happy ending when it wasn’t on the menu. Accusations are that the green guru turned into El Grope to such an extent that a police report was filed. Tom has salacious bits if you don’t want to read it all. Tipper is now odds-on favorite to win the top honors at the 2010 Good Timing Awards.
One thing to be grateful for, that El Grope wasn’t around in the 1930‘s.
Al continued to promote the Gore enrichment scheme with an op-ed in the Wall Street Journal. It’s behind a subscription wall, but the great man excerpted a little for us peons:

Warming in Last 50 Years Predicted by Natural Climate Cycles
by Roy W. Spencer, June 6th, 2010
One of the main conclusions of the 2007 IPCC report was that the warming over the last 50 years was most likely due to anthropogenic pollution, especially increasing atmospheric CO2 from fossil fuel burning.
But a minority of climate researchers have maintained that some — or even most — of that warming could have been due to natural causes. For instance, the Pacific Decadal Oscillation (PDO) and Atlantic Multi-decadal Oscillation (AMO) are natural modes of climate variability which have similar time scales to warming and cooling periods during the 20th Century. Also, El Nino — which is known to cause global-average warmth — has been more frequent in the last 30 years or so; the Southern Oscillation Index (SOI) is a measure of El Nino and La Nina activity.
A simple way to examine the possibility that these climate cycles might be involved in the warming over the last 50 years in to do a statistical comparison of the yearly temperature variations versus the PDO, AMO, and SOI yearly values. But of course, correlation does not prove causation.

The IPCC consensus on climate change was phoney, says IPCC insider June 15, 2010

The IPCC consensus on climate change was phoney, says IPCC insider
By Lawrence Solomon
National Post, June 13, 2010
The UN’s Intergovernmental Panel on Climate Change misled the press and public into believing that thousands of scientists backed its claims on manmade global warming, according to Mike Hulme, a prominent climate scientist and IPCC insider. The actual number of scientists who backed that claim was “only a few dozen experts,” he states in a paper for Progress in Physical Geography, co-authored with student Martin Mahony.
“Claims such as ‘2,500 of the world’s leading scientists have reached a consensus that human activities are having a significant influence on the climate’ are disingenuous,” the paper states unambiguously, adding that they rendered “the IPCC vulnerable to outside criticism.”
Hulme, Professor of Climate Change in the School of Environmental Sciences at the University of East Anglia – the university of Climategate fame — is the founding Director of the Tyndall Centre for Climate Change Research and one of the UK’s most prominent climate scientists. Among his many roles in the climate change establishment, Hulme was the IPCC’s co-ordinating Lead Author for its chapter on ‘Climate scenario development’ for its Third Assessment Report and a contributing author of several other chapters.

Why scientists get it wrong
by David Archibald
Quadrant Online, June 1, 2010
Edited extract: “Why did so many scientists get it wrong?” from David Archibald’s book – The Past and Future of Climate:
Click to order book
If the data and forecasts in this book are correct, then the Intergovernmental Panel on Climate Change (IPCC), the National Academy of Sciences in the United States, the Royal Society in the United Kingdom, the Bureau of Meteorology and the CSIRO in Australia are all wrong. How can this be? Firstly, there aren’t that many scientists involved in the IPCC deliberations. The inner core is possibly twenty souls. Secondly, they were untroubled by the necessity to concoct fraudulent data to get their desired results. The only unknown question regarding the IPCC scientists is “Did they actually believe in the global warming that they were promoting?”
It turns out that they did, and possibly still do. That is shown by the Climategate emails released on 20th November, 2009. The Climategate emails are a selection of emails amongst members of the inner core plus minor characters. The fact that the IPCC scientists believed in the global warming they were promoting means that their morality at that level was better than expected, but it also means that they are a lot more stupid than expected. Nevertheless, their behaviour in promoting the notion of global warming using fraudulent statistics is reprehensible and hopefully they will be duly punished in this world or the next.
