ABSTRACT. The Trump administration is in the process of undoing what were the two central planks of President Obama’s climate policy: First, Trump has called for a review of how the social cost of carbon is calculated in used in analyses of regulatory rule making and, second, Trump has announced that the United States is withdrawing from the Paris Agreement. In this paper I examine some of the conservative critics’ objections to the first plank: calculations of the social cost of carbon in climate cost benefit analyses. I argue that while some of these criticisms are justified, the criticisms end up strengthening arguments for the importance of the second plank: the urgent need for an ambitious climate policy, in accord with the Paris Agreement, as precaution against exposing others to the risk of catastrophic harms.
As the record-breaking heat of 2016 continues into 2017, making it likely that 2017 will be the second hottest year on record just behind the El Niño year 2016, and as Arctic heat waves pushing the sea ice extent to record lows are mirrored by large scale sheets of meltwater and even rain in Antarctica—the Trump administration is taking dramatic steps to undo the Obama administration’s climate legacy.
In its final years, the Obama administration pursued two principal strategies toward climate policy. First, by signing the Paris Accord it committed the U.S. to contribute to global efforts to hold “the increase in the global average temperature to well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5°C
