Monster List: Skeptics Have Touted "Global Cooling" Theory Anywhere They Could

As word spreads about the Associated Press blind test examining the global cooling theory, which I wrote about earlier this week, I began to wonder how many times skeptics have tried to push this global cooling myth recently on the Internets.

So I perused the first 10 pages of results on Google for the term “global cooling” and discovered plenty of examples of skeptics hawking their global cooling theory on the usual suspect blogs and media outlets (with a few exceptions like the much-ballyhooed BBC News article earlier this month). Here is a sampling of the results of the search:

Title: “Three Decades Of Global Cooling”
“Earth’s climate is influenced by many things, the least of which is the internal combustion engine. We and reputable scientists have noted the earth has cooled during the last decade, a period in which the sun has grown very quiet with little or no sunspot activity.”

BBC News | October 9, 2009
Article title: What happened to global warming?
“This headline may come as a bit of a surprise, so too might that fact that the warmest year recorded globally was not in 2008 or 2007, but in 1998. But it is true. For the last 11 years we have not observed any increase in global temperatures.”

Christian Science Monitor | October 10, 2009
“The Earth isn’t warming right now, is why. It may even be cooling down somewhat. Five major climate centers around the world agree that average global temperatures have not risen in the past 11 years, according to the BBC. In fact, in eight of those years, global average temperatures dipped a tad.”

Statisticians Confirm: No Global Cooling Despite Skeptic Spin

In a massive blow to the climate skeptic movement, the Associated Press has conducted a blind test of statisticians that unequivocally confirms that no global cooling trend exists

Despite the best efforts of a small handful of climate skeptics, who argue that the globe has cooled rather than warmed since the record hot year of 1998, no such cooling trend has taken place.

The Associated Press conducted the blind test by sending global temperature data from NOAA and NASA to four independent statisticians who were not told what the data represented, but simply asked to perform a common statistical analysis to look for trends in the data.

The statisticians “found no true temperature declines over time,” and in fact identified “a distinct decades-long upward trend in the numbers,” the AP reports.

Several statisticians quoted in the AP piece slam the climate skeptics who “cherry-pick” data in a “particularly suspect” attempt to denounce global warming.  Efforts to portray a global cooling trend since the record hot year of 1998 are “not scientifically legitimate,” and are the result of “people coming at the data with preconceived notions,” according to David Peterson, a retired Duke University statistics professor who analyzed the data for AP.

“To talk about global cooling at the end of the hottest decade the planet has experienced in many thousands of years is ridiculous,” said Ken Caldeira, a climate scientist at the Carnegie Institution at Stanford.

“Ridiculous” indeed, but that has not stopped the handful of loud-mouthed climate skeptics from spreading this false claim.  Their efforts have proven successful at confusing the public, thanks in large part to the Drudge Report, FOX News and lazy journalists who fail to fact-check the skeptic arguments, providing oxygen to their baseless claims.

The Associated Press conducted a simple exercise that any self-respecting news outlet concerned with the facts rather than the confusionist spin could duplicate easily.  Don’t expect this news to silence the skeptics, but if you are a journalist, please let the skeptics talk amongst themselves, rather than polluting the public discourse any further.  And if you are a concerned news consumer, please do hold accountable any news outlet that continues to ignore this starkly obvious fact: there is no global cooling.  There definitely is global warming. 

It really is that simple.  Now can we talk about the critically important matter of how to address climate change with just a few weeks left until the Copenhagen Climate Summit?

It's Getting Hot in Here

The US National Climatic Data Center just released data that shows that the period between January and June of 2007 constitutes the second warmest on record for that time period.

During the same period, the Southeast has been the second driest on record.
