The Spin Cycle is a reoccurring feature based upon just how much the latest weather or climate story, policy pronouncement, or simply poo-bah blather spins the truth. Statements are given a rating between 1-5 spin cycles, with less cycles meaning less spin. For a more in-depth description, visit the inaugural edition.
Well, well, well. The EPA has finally gone and done it. They have actually calculated the climate change impacts projected to result of one of their climate change regulations—in this case, the proposed rules for the efficiency standards for medium and heavy duty vehicles.
What they found was hardly surprising—the climate impacts from the proposed regulations will be vanishingly small.
The EPA calculates that the amount of global temperature rise averted by the end of the 21st century from the proposed regulations to be… wait, this is too good to paraphrase. From the EPA:
The results of the analysis demonstrate that relative to the reference case, by 2100 projected atmospheric CO2 concentrations are estimated to be reduced by 1.1 to 1.2 part per million by volume (ppmv), global mean temperature is estimated to be reduced by 0.0026 to 0.0065 °C, and sea-level rise is projected to be reduced by approximately 0.023 to 0.057 cm.
Did you catch that? According to the EPA’s own calculations, their regulation mandating the fuel economy of medium and light duty trucks avoids somewhere between twenty-six ten-thousandths and sixty-five ten-housandths of a degree of future global warming. In other words, it is a useless measure when it comes to influencing the future course of global temperature. If the EPA wants to regulate the fuel efficiency of trucks, it needs to justify it for reasons that don’t relate to climate change.
