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

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

It's Climategate 2.0! (…not)

In December, the Goddard Institute for Space Sciences (GISS) published over 200 pages of internal emails as required by a Freedom of Information Act (FOIA) request by the Competitive Enterprise Institute (CEI). The emails involved how the GISS handled responding to a number of requests for information, data, and code from Steve McIntyre, founder of the climate disruption-denier website ClimateAudit.org. Clearly there was no metaphorical “smoking gun” in the emails, because the CEI didn’t crow about a likely Climategate 2.0 following the emails’ release.

However, today it appeared that Judicial Watch and number of large climate denier blogs didn’t get the memo. Continue reading

Nuz Flash! Old story sez Sun makz climate change! Oh noes!!1!

dasunToday, Memeorandum featured a post by climate disruption denier Michael Andrews and writer for the website DailyTech that claimed, among other things, that “even NASA’s own study acknowledges that solar variation has caused climate change in the past.” Not exactly news, but given that this article has been linked by other prominent denier sites like American Thinker, Newsbusters, and WattsUpWithThat, I figured that it was worth a little more looking.

And I’m glad I did, because I came across a great post at The Phoenix Talking Politics blog that pointed out something I’d missed: Andrews got all hot and bothered by a general interest piece that ran in ScienceDaily in May, 2008.

Oops.

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

giss2008

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.

The Weekly Carboholic: UK says Greenpeace stopped climate damage

carboholic

In an unexpected development, jurors in the UK acquitted six Greenpeace activists in a case involving £35,000 ($62,591) worth of damages to a coal-fired power plant. The defense had argued that a 1971 law (Criminal Damage Act 1971) permitting damage to property in order to prevent even greater property damage applied to the activists. Specifically, the Greenpeace activists claimed that they were preventing “damage to properties worldwide caused by global warming”. And the jurors agreed.

This case defines a precedent for UK law that will be difficult to sort out. Does it mean that Parliament comes back through and refines the law to prevent this kind of “abuse” in the future? Or does it mean that the UK cannot build any more new coal plants without carbon capture and sequestration (CCS)? Continue reading

2007 global temperature second hottest since 1880

2007 GISS data-map

On January 16, 2008, Dr. James Hansen of NASA’s Goddard Institute for Space Sciences (GISS) released the summation of temperature data for 2007 with apparently very little fanfare. Given the data collected by Dr. Hansen, the lack of fanfare itself might well be notable. But regardless, the data itself bears more public attention that it’s had.

2007 is now tied with 1998 as the second hottest year for global temperature in a century. Continue reading
