The Environmental Protection Agency (EPA) has received two petitions asking for official review of a regulatory document that served as critical leverage for the Obama administration to issue global warming regulations.
Two groups — Competitive Enterprise Institute (CEI) and the Concerned Household Electricity Consumers Council (CHECC) — claim EPA’s 2009 “endangerment finding” should be updated with new evidence invalidating the agency’s previous claim greenhouse gasses threatened public health.
CEI filed its petition in late February, but did not publicize it. Sam Kazman, CEI’s general counsel, told The Daily Caller News Foundation that Trump will have a difficult time rolling back EPA’s global warming regulations without invalidating the “endangerment finding.”
“I think they’re going to have a lot of trouble on the other things they want to get done without addressing the endangerment finding,” Kazman said.
CHECC sent its petition to EPA Jan. 20, during Trump’s inauguration. CHECC is only now publicizing this, along with CEI, to urge the Trump administration to re-examine the endangerment finding now that the president issued an executive order to rolling back Obama-era global warming policies.
CHECC’s petition relies on a 2016 study that “failed to find that the steadily rising atmospheric CO2 concentrations have had a statistically significant impact on any of the 13 critically important temperature time series data analyzed.”
“In sum, all three of the lines of evidence relied upon by EPA to attribute warming to human GHG emissions are invalid,” reads CHCC’s petition. “The Endangerment Finding itself is therefore invalid and should be reconsidered.”
One of EPA’s lines of evidence was predicated on the existence of a “tropical hotspot” where global warming would be most apparent. Climate models predicted there’d be enhanced warming in the tropical troposphere.
CHECC’s 2016 study — by economist James Wallace, climatologist John Christy and meteorologist Joseph D’Aleo — found the tropical hotspot “simply does not exist in the real world.”
The co-authors found that once El Ninos and other natural factors were taken into account, “there is no ‘record setting’ warming to be concerned about.”
“These analysis results would appear to leave very, very little doubt but that EPA’s claim of a Tropical Hot Spot (THS), caused by rising atmospheric CO2 levels, simply does not exist in the real world,” according to CHECC’s 2016 study.
EPA issued its endangerment finding for six greenhouse gases, including carbon dioxide, in 2009, citing three lines of evidence to claim such emissions from vehicles “endanger both the public health and the public welfare of current and future generations.”
That finding allowed the Obama administration to move forward with an aggressive agenda to clamp down on greenhouse gas emissions from vehicles, power plants and other industrial facilities.
