Another defender of limited government (and sound science) has petitioned U.S. Environmental Protection Agency to reopen the regulatory process that led to EPA’s controversial endangerment finding, arguing that new information casts doubt on the scientific integrity of the determination. The Pacific Legal Foundation (PLF), a Sacramento, Calif.-based group that defends individuals against large, intrusive government, filed an administrative petition with EPA last week that challenges the agency’s finding on procedural grounds. The petition to the EPA is available at PLF’s web site.

According to the filing, EPA must reopen the proceedings surrounding its determination that greenhouse gases threaten public health and welfare, in light of recent controversy over e-mails released from prominent climate scientists whose work formed the very foundation of the Intergovernmental Panel on Climate Change (IPCC)’s 4th assessment on climate change (2007).…

“The quality of [truth-seeking] depends on a willingness to respectfully engage in open, honest, and objective debate, to challenge … our own beliefs…. As the philosopher, economist, and Anglican bishop Richard Whately observed: ‘It is one thing to wish to have truth on our side, and another thing to wish sincerely to be on the side of truth’.”

A week ago I posted a tribute to Julian Simon (1932–1998) on the anniversary of his death. The post was picked up elsewhere in the blogosphere, and I received a number of emails from academics who remarked about how much they appreciated Simon’s personal kindness and scholarly qualities. Steve Horwitz wrote at Coordination Problem:

[Simon] was a model of what a scholar can and should be:  well-read, totally on top of the relevant data, fearless about taking on sacred cows, unafraid to be in your face but always with a smile on his face. 

[Editor note: The author has added an update at the end showing why it can be reasonably argued that anthropogenic greenhouse gases may be responsible for less than half of the observed warming since the mid-20th century]

Back in December, the EPA announced that it had determined that greenhouse gases released by human activities “threaten the public health and welfare of current and future generations.” This “Endangerment Finding” is the first step toward EPA’s issuing regulations aimed at restricting GHG emissions in the U.S.

Unfortunately for the EPA, a major pillar of support of the Endangerment Finding—that “most” of the “observed warming” since the mid-20th century is from greenhouse gas emissions from human activities—has been shown by recent scientific research in major peer-reviewed scientific journals to be largely in doubt.

Add this result to the list of problems that seems to grow longer with each passing day as more IPCC gaffes are uncovered and Climategate emails are parsed.…

Joseph Romm heavily edits the comments at his top-rated energy/environmental blog, Climate Progress, a project of the Center for American Progress. (The more academic, one-post-per-day MasterResource is #14 of 2,800 “green blogs” as of 1/31/10 per Technorati, not too bad for being 13 months old.)

Dr. Romm will not publicly debate his distinguished opponents either, just as Paul Ehrlich refused to debate the late Julian Simon. Though thin-skinned and trigger happy, Romm has not attempted to rebut a four-part post at the Breakthrough Institute by Michael Shellenberger, Ted Nordhaus, et al., Joe Romm and Climate McCarthyism, a widely disseminated and discussed event on the Left. (Updates on the Romm series are available at the Breakthrough Institute blog.)

Nor will Romm show the courage of his convictions by betting on his predicted global warming trend, which has led some to speculate that Romm deep down is really a global lukewarmer.…
