Polar Bears and Climate Change -- A Second Look
Recently, a district judge ordered the Department of the Interior to reconsider its listing of polar bears as "threatened" rather than "endangered" under the Endangered Species Act. In re Polar Bear Endangered Species Act Listing and Section 4(d) Rule Litigation, No. 1:08-mc-764-EGS (D.D.C. Nov. 4, 2010). The polar bear faces a threat because of the disappearance of sea ice, which the government attributes to climate change. Under the listing decision, if the polar bear is "threatened," one cannot sue emitters of greenhouse gases for violations of the Endangered Species Act, 16 U.S.C. § 1531ff. See 73 Fed. Reg. 28,212 (May 15, 2008). That would not be true if the polar bear were classified as "endangered."
The specific question addressed by Judge Sullivan was whether the government properly relied on the "plain meaning" of the term to decide that the polar bear was not "endangered." The statute contains ambiguities that the government has to address. The court remanded the rule for the limited purpose of providing that additional explanation, and gave the government a deadline of December 23. He will then consider the substance of the challenges to the rationale for the "threatened" listing.
On November 3, Karl Rove is reported to have announced to a large meeting of the natural gas industry that "climate is gone." Comprehensive federal climate change legislation may be "gone," but the risk is not. As we have previously commented, greenhouse gas emissions now face regulation under the Clean Air Act, and that is an awkward, expensive, and uncertain tool for the purpose. As In re Polar Bear suggests, the litigation risk to greenhouse gas emitters also persists, and on relatively indirect theories

with less fuel will do better. Cities with better transit will, all other things equal, be where businesses and people want to be. In the process, the nation as a whole will become more efficient as activity flows to those places. As a practical matter, capital improvements to urban transit systems are just not going to be funded by the bus fairy. Pennsylvania tried one interesting approach to having one transportation mode help fund the sort of capital improvements that climate-friendliness and energy-efficiency would require. We see here an example of the sclerotic complexity that rebuilding the economy for an energy- or carbon-constrained world encounters.
