Wind farms affect local nighttime temperatures, not global warming

On April 29, a paper about how wind farms affect surface temperatures was published online by the journal Nature Climate Change. The authors of the paper found that wind farms increase the nighttime surface temperature within and immediately downwind of the wind farm because the turbines mix up cold surface air with warmer air from up higher off the ground. What the authors did not find, however, was that wind farms were having any global effect on climate disruption. But if you only read articles and blogs from Forbes, Fox News, The Star Ledger, the UK’s Daily Mail, The National Review‘s Planet Gore blog, The Free Republic, etc., you’d never know that.

In fact, if those were your only sources of information, you’d believe that the paper was all about how wind farms were yet another cause of global warming, when in fact it says nothing of the sort. Continue reading

Climate science discussion between Burt Rutan and Brian Angliss

On January 27, I wrote an “open letter” to Burt Rutan, aerospace engineer and former CEO of Scaled Composites, expressing my disappointment that he would co-sign a commentary in the Wall Street Journal that contains incorrect and misleading information on climate science and economics. On January 28th, Rutan responded in the comments. He also CCed his response to Anthony Watts, who published Rutan’s response on Wattsupwiththat.com. What transpired is a huge number of comments that essentially drowned Rutan’s and my exchanges.

This post extracts from the original comment thread just Rutan’s and my responses, ignoring all the other comments, good, bad, or ugly.

Comments on this post are closed, and any further exchanges between Rutan and I from the original post will be posted here for clarity. If you have something to say about what we’re talking about, please comment in the original post’s comment thread instead – everything here is also there. Continue reading

Heartland Institute's latest climate-related media advisory filled with the usual distortions

The Heartland Institute has a history of distorting peer-reviewed papers, lying in newspaper editorials and Institute blogs, and claiming extensive scientific expertise where little actually exists with respect to climate science and the reality of human-driven climate disruption. Given this history, the distortions in the Heartland Institute’s latest media advisory regarding the results of the Berkeley Earth Surface Temperature (BEST) project are only to be expected.

BEST analyzed more surface temperature data than any other study had previously and concluded that the established global temperature records were accurate. In this way, BEST confirmed what every climate realist already knew from three surface datasets and two satellite datasets – that the globe is warming and that the best available science indicates that the urban heat island effect has a minimal impact upon the measurements. However, the Heartland Institute’s media advisory claims that “the paper is seriously flawed,” attributing that statement to James M. Taylor, senior fellow for environment policy at the Heartland Institute.

It’s at this point, the second sentence of the media advisory, that the distortions start. Continue reading

21 expert climate scientists refute Monckton’s House testimony

On May 6, 2010, Christopher Monckton, Viscount of Brenchley, was invited by the Republican members of the House Select Committee on Energy Independence and Global Warming to present testimony that contradicted over 100 years of established chemistry, physics, and climatology. Monckton, a non-scientist who has a long history of making erroneous claims, was seated as and equal beside four scientists with PhDs in their respective climate-related fields.

Earlier this month, a group of climate scientists submitted a detailed rebuttal of Monckton’s testimony to the House. Continue reading

Final CRU email review considers, overwhelmingly rejects critics’ accusations of misconduct

As a result of the unauthorized publication of nearly 1100 private emails from the Climatic Research Unit (CRU) in November, 2009, five separate inquiries were empaneled to look into whether or not the CRU researchers had committed research misconduct, broke Freedom of Information laws, or inappropriately biased the results of the IPCC Fourth Assessment Report (AR4) published in 2007. All four of the other reviews, two by Pennsylvania State University, one by the UK Parliament House of Commons Science and Technology Committee, and one by Lord Oxburgh of the Royal Society, concluded that the CRU scientists had not engaged in either scientific misconduct or the manipulation of the peer review process, although one inquiry found that the scientists hadn’t been as open with their data and methodologies as they should have been.

The last of the five reviews, the Independent Climate Change Email Review (ICCER), published its findings on July 7, 2010. In general terms, the ICCER found that the CRU scientists’ “rigor and honesty” were not in doubt and that there was no “evidence of behavior that might undermine the conclusions of the IPCC assessments.” However, the ICCER found that there was a “consistent pattern of failing to display the proper degree of openness” with respect to sharing data. These broad conclusions largely agree with the conclusions of all four of the other inquiries. Continue reading

Climategate accusations shrivel under the glare of multiple investigations

For the second time in two weeks, an investigation has found that there was neither a conspiracy to deceive the public nor any scientific misconduct present in the scientific research of the scientists of the Climatic Research Unit (CRU) at the University of East Anglia (UEA). These scientists were at the center of the controversy created by the Climategate email theft.

The House of Commons Science and Technology Committee tasked itself with investigating what the MPs considered critical points, namely whether the scientific work of the CRU scientists was transparent and open, whether CRU had committed scientific misconduct, and whether the CRU committed any breaches of the UK’s Freedom of Information (FOI) law. In order to address each of these key concerns, the Committee collected a significant number of statements as evidence and looked into the various specific accusations made in those statements.

What the Committee found was that there were a few problems and a widespread disregard for FOI in the wider University culture, CRU’s research was reasonably transparent and free of obvious scientific malpractice. Continue reading

The Weekly Carboholic: independent statisticians reject recent global cooling claims in blind analysis

cooling

Climate disruption deniers have been claiming for years now that the global temperature has been cooling down, even though the temperature data clearly shows that it isn’t. Scientists and statisticians have pointed out that, mathematically speaking, the recent reduced warming trend is well within the noise, or put another way, it’s weather, not climate.

A new report by the Associated Press reveals what many of us knew already – the denier’s claims don’t hold water, statistically speaking. The report is intriguing because the AP provided their data to four independent statisticians without telling them what it was, and all four found that the slower warming of the past decade was statistically insignificant with respect to the actual data.

The Weekly Carboholic: as the Arctic melts

“I was in Siberia a few weeks ago, and I am now just back in from the field in Alaska. The permafrost is melting fast all over the Arctic, lakes are forming everywhere and methane is bubbling up out of them.”

“Lakes in Siberia are five times bigger than when I measured them in 2006. It’s unprecedented. This is a global event now, and the inertia for more permafrost melt is increasing.”

This is what University of Alaska ecologist Katey Walter is quoted as saying in a New Scientist article published last week titled Arctic meltdown is a threat to humanity. Continue reading

The Weekly Carboholic: GISS and NOAA expect 2009 to be hotter than 2008

Last year, the Goddard Institute for Space Studies (GISS) released a prediction that record global temperatures should be expected in the next 2-3 years. GISS released their annual wrapup of the 2008 global temperature, and with it an updated prediction: 2008 was the coolest year since 2000 because of a strong La Nina in the tropical Pacific, and record temperatures are expected in the next 1-2 years.
