The Endangered Species Act (ESA), with its reputation as the nation’s strongest environmental law, might be expected to impose some limits on greenhouse gas (GHG) emissions adversely affecting listed species due to rising global temperatures. Although the federal government recently conceded that some species warrant listing because of climate change, the accompanying listing decisions revealed a federal refusal to apply the ESA to constrain GHG emissions. In this Article, we explain those decisions—involving the American pika, the polar bear, the wolverine, and the Gunnison sage-grouse—and their implications. We conclude with some surprising observations about the Obama Administration’s apparent endorsement of Justice Scalia’s approach to the ESA’s habitat protections, the Administration’s endorsement of constitutional standing rules to limit the effective scope of the statute, the growing significance of the distinction between endangered and threatened species, and the unintended boomerang effects of the administrative reforms of the statute in the 1990s.
