Economywide legislation to address climate change will be ineffective unless it addresses greenhouse gas emissions from agriculture and land use. Yet incorporating these sectors into the most popular policy proposal—a carbon tax—carries legal risk that policymakers and legal commentators have ignored. This Article explores whether a carbon tax, as applied to agriculture and land use, is a direct tax within the meaning of the Constitution; it concludes that text, history, and Supreme Court precedent up through National Federation of Independent Business v.

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.

I. Introduction and Overview

Editors' Summary: Since the Supreme Court's decision in Rapanos v. United States, courts, practitioners, and scholars have continued to discuss Justice Anthony M. Kennedy's significant nexus test. Under this test, to protect a wetland one must establish that there is a significant nexus between the wetland and a traditional navigable water. In this Article, authors William W. Sapp, Rebekah Robinson, and M. Allison Burdette suggest that the nearer a traditional navigable water is to the wetland, the better the chance of establishing that there is a significant nexus between the two.

The 1999 National Nuclear Security Administration Act (NNSA Act) threatens to reverse 20 years of reforms and court decisions intended to bring the U.S. Department of Energy (DOE) into compliance with environmental laws and regulations. The NNSA Act, enacted in the wake of allegations of spying at Los Alamos nuclear weapons laboratory in New Mexico, established a semi-autonomous agency within DOE—the National Nuclear Security Administration (NNSA). The NNSA operates nine laboratories and facilities within the U.S. nuclear weapons complex.

Under the public welfare doctrine, certain regulatory crimes require no showing of the traditional mens rea, or "guilty mind," as a predicate to criminal liability. The doctrine has been used to relax intent requirements in criminal statutes when the public welfare is at stake and is predicated upon the fact that the defendant had notice that the dangerous activity is regulated. A majority of courts place the criminal provisions of the Clean Water Act (CWA) within the public welfare doctrine.
