The Emergence of Climate Law Courses

Obama law school

It's an increasingly widespread law school course.

The U.S. legal system has only begun to address climate change in the past ten or fifteen years. It was inevitable that this subject would infiltrate basic environmental law courses, especially given that there have now been three Supreme Court cases on the subject.  But climate change is now increasingly the subject of separate courses […]

Why Michael Mann’s Defamation Suit Against Climate Denialists Is the Right Move

Michael Mann

With the facts on his side, there's no reason to hide

Dr. Michael Mann, one of the country’s leading climate scientists, has been harassed, threatened, and berated for his views that human actions are contributing to global climate change. But not just from anonymous commenters on websites — from leading publications like the National Review Online. After being compared to Jerry Sandusky and having the credibility […]

New research from Berkeley Law finds that the U.S. Department of Agriculture can act now to reduce greenhouse gas emissions

The U.S. Department of Agriculture (USDA) is much in the news these days, as it implements the massive and always-controversial farm bill, works to improve access to national forests, strives to enhance the U.S. position in international agriculture markets, and wrestles to contain this season’s extensive wildfire activity. What is less obvious to many is […]

Water and Climate Change, Backwards

California State Water Project Irrigation Canal: Do We Want More Cement?

Will Conserving Water Contribute to Global Warming?

All of us (except Republicans and adherents of Movement Conservatism) know that climate change is dangerous for rising temperatures, but also because of its effects on other natural resources.  Most significantly, it is hardly news that increasing and variable temperatures will reduce, for example, the Sierra snow pack and cause greater evaporation, eventually leading to […]

Hydrogen “Fool” Cells Vs. Electric Vehicles

The debate over the best clean vehicle technology

California recently committed to spending $50 million on 28 public hydrogen fuel cell charging stations, throwing gasoline (bad pun) on the fire of a growing debate: electric vehicles vs, hydrogen fuel cells as the carbon-free vehicle technology of the future. California policy makers seem to think it may be both, based on their spending to […]

New Pritzker Brief from UCLA Law on Making Public Transit Work

Fellow blogger Ethan Elkind has spent a lot of time researching the history, politics, and future of transit in California.  Earlier this year he published Railtown, a fascinating portrait of the fight over development of the L.A. Metro rail system, revealing the degree to which that development has been driven by good old-fashioned politics and even intrigue […]

Mining for Votes In Coal States: Paul Ryan On Climate Change

Paul_Ryan_VP_announcement

Whatever you think of his budget proposals, his climate views are irresponsible.

For years, Paul Krugman has been decrying Paul Ryan’s reputation as a reputable analyst of budget issues.  That’s not my area of expertise, and I’m agnostic on that issue.  But Ryan’s views about climate change don’t bespeak serious thought about the issues. The Christian Science Monitor reports that last Ryan spoke about climate change in […]

Guest Blogger John Nagle: The Clean Air Act Applies to Greenhouse Gases Because of What Congress Said, Not Because of What Congress Intended

A Reply to Megan Herzog

In my recent CNN op-ed and in her previous post, Megan Herzog and I agree that the Supreme Court has properly interpreted the Clean Air Act (CAA) to apply to the emission of greenhouse gases. We just disagree about the correct manner in which to reach that conclusion. Judges and scholars generally favor an originalist […]

Climate Change Adaptation Strategy: Can California Do More?

Is Increased Reliance on the Public Trust Doctrine an Essential Part of Effective State Adaptation Policy?

I often tell students in my Climate Change Law and Policy course that adaptation–that is, how we can best adapt to the unavoidable impacts of climate change–is the poor stepchild of the debate over greenhouse gas emissions and climate change.  By that I mean that climate change mitigation (i.e., how to reduce greenhouse gas emissions) generates far more […]

Debating the Relationship between the Healthcare Fight and Climate Regulation

Last week, conflicting federal court decisions regarding the Patient Protection and Affordable Care Act, commonly known as the ACA or “Obamacare,” set the nation abuzz. In Halbig v. Burwell, the D.C. Circuit Court of Appeals struck down an Internal Revenue Service (IRS) regulation providing federal subsidies to low-income taxpayers who purchase health insurance through a […]
