Greenhouse gas emissions from transportation in the United States have remained persistently high. One cause is common low-density land use patterns that make most Americans dependent on automobiles. Reducing these emissions requires increasing density, which U.S. local government law makes difficult to achieve through the political process. Mount Laurel, a 1975 New Jersey Supreme Court case that addressed an affordable housing crisis by restraining local parochialism, provides a potential solution.

Limiting future temperature increases and associated climate change requires immediate action to prevent additional carbon dioxide being released into the atmosphere and to lower the existing atmospheric carbon dioxide load. This could be advanced through carbon capture and storage (CCS), which involves collecting carbon dioxide that would otherwise be released by power plants or similar facilities and injecting it into underground geologic formations, where it will remain permanently sequestered.

Access to water is a fundamental climate change issue in North America and internationally. It is related to significant political, social, and ecological struggles that indigenous peoples face, and governments and courts so far have done little to address these inequities.

Climate change has important implications for the management and conservation of natural resources and public lands. The federal agencies responsible for managing these resources have generally recognized that considerations pertaining to climate change adaptation should be incorporated into existing planning processes, yet this topic is still treated as an afterthought in many planning documents. Only a few federal agencies have published guidance on how managers should consider climate change impacts and their management implications.

Perhaps Congress should throw up its hands and move on to something more manageable than global climate change. Richard Lazarus asserts that the challenges of enacting effective national strategies for mitigating and adapting to changes in the Earth's climate are not just "wicked," but "super wicked," meaning they defy resolution.

Editor's Summary: In 2003, the U.S. Supreme Court issued its most recent pronouncement on the executive foreign affairs preemption doctrine in American Insurance Ass'n v. Garamendi. In this Article, Kimberly Breedon argues that lower courts are prone to overbroad applications of Garamendi because the Court assumed the presence of three elements when it developed the standard for executive foreign affairs preemption of state law: (1) formal source law; (2) nexus to a foreign entity; and (3) indication of intent by the executive to preempt the state law under challenge.
