Also in the works, an inquisition of the EPA and the resurrection of “Climate-gate”:

…Senior congressional Republicans plan to launch a blistering attack on the Obama administration’s environmental policies, as well as on scientists who link air pollution to climate change.

The GOP’s fire will be concentrated especially on the administration’s efforts to use the Environmental Protection Agency’s authority over air pollution to tighten emissions controls on coal, oil and other carbon fuels that scientists say contribute to global warming.

The attack, according to senior Republicans, will seek to portray the EPA as abusing its authority and damaging the economy with needless government regulations.

In addition, GOP leaders say, they will focus on what they see as distortions of scientific evidence regarding climate change and on Obama administration efforts to achieve by executive rule-making what it failed to win from Congress.

Several key Republican Congressmen — most notably Rep. Darrell Issa (R-Vista), who could take over the chairmanship of the House Oversight and Government Reform Committee — have said they plan to investigate climate scientists they contend manipulated data to prove the case that human activity is contributing to global warming.

…The primary focus will be on the EPA’s determination last year that carbon dioxide and other emissions endanger public welfare by contributing to climate change. Armed with this finding, the EPA has moved to reduce greenhouse gases by mandating emissions reductions in vehicles and will soon move to regulate stationary sources like power plants and factories.

House Republicans like Issa and James F. Sensenbrenner Jr. (R-Wis.) of the Select Committee on Energy Independence and Global Warming have criticized the EPA for basing its endangerment finding on what they consider flawed research. Republicans assert that the science on climate change is not yet “settled,” despite the vast global scientific consensus about its human causes.

Specifically, Issa has said he wants to investigate the “Climategate” scandal that broke late last year, when hackers illegally obtained and released thousands of emails of climate scientists working with a leading British laboratory.

Climate skeptics, among them House Republicans like Issa, contend that the sniping and harshness in some emails prove that climate scientists suppressed dissenting studies and that science showing the link between greenhouse gases and climate change is biased and tainted.

Like officials within the administration, scientists around the country who expect to be investigated by Issa and others are getting legal advice on how to best protect themselves. Among them is Michael E. Mann, professor of meteorology at Penn State University and one of the researchers who developed the “hockey stick” graph that shows a recent spike in global temperatures.

Issa named Mann in a letter to the EPA as a scientist whose work was not “unbiased, accurate or reliable.”
