Climate Adaptation

Trump’s FEMA Review

Trump’s FEMA Council has reported back. Its basic strategy is flawed.

After much delay, Trump’s FEMA Council has reported back.  While the report has some good ideas, much of it resolves around the same strategy: move current problems from the federal government to the states rather than fixing them.  Moving responsibilities around doesn’t make them go away.  And the reality is that many states will be unable to manage these tasks efficiently.  They also lack the federal government’s capacity and economies of scale.  And while the federal government will do less itself, it will become more intrusive on state operations, so there’s no clear gain in terms of federalism.

Harmful Activities, the Duty to Rescue, and Climate Change

A concept from tort law suggests another argument for international climate adaptation funding.

Do countries that caused past carbon emissions have a duty to help pay for adaptation and disaster response?  Much of the argument about this is phrased in terms of damages for past actions, not unlike arguments that oil companies should pay damages for oil spills. Tort law suggests another way of looking at the issue, one that doesn’t depend on whether the past emissions themselves give rise to duty for reparations. Instead, it depends on the principle that people whose activities contribute to accident risks, even innocently, have a duty to assist victims.

Never Give Up! Every Ton of Carbon We Can Cut Still Matters

A figure demonstrates the possible changes in Celsius of global temperatures at 1.5, 2. and 4 degree Celsius increased in global warming.

It’s easy to be disheartened when we miss climate targets. But climate change isn’t a yes/no thing. It’s a matter of degree.

It’s easy to lose heart about our prospects for limiting climate change. The US has pulled out of international climate negotiations. Most of the countries that joined the Paris Agreement have missed targets , targets that weren’t aggressive enough in the first place.  The 1.5 °C target is already basically out of reach.  Is time to give up on slowing climate change and focus on adapting to it?  The answer is no.  Here’s why.
Climate change is a matter of degrees. That sounds like a truism or a pun, but it’s true in a deeper sense. There is no point past which further warming becomes irrelevant. degree, and every fraction of a degree makes things that much worse.

What Does Wildfire Resilience Cost?

Electric grid

A new UCLA Law report focuses on wildfire liability costs and wildfire mitigation costs in the transmission context.

When it comes to updating transmission lines and other wildfire-related costs, how much of the burden should fall on utility ratepayers? That’s one of the questions at the heart of a new report published by the UCLA Emmett Institute.   First, some context: California saw its hottest temperatures ever recorded in March this year. With a hotter climate come more frequent and …

Climate Issues in the 2026 Governor’s Race: Water

The Seal of the Governor of the State of California has the California flag in the center with a sun in he background and orange California poppies at the bottom.

Third in a series of posts outlining key challenges and opportunities facing California’s next governor

California’s next Governor will need to grapple with a complex array of local, state, and regional water issues. Climate change, shifting population dynamics, and a changing economy are stressing California’s water systems and intensifying conflict over water resources. Floods and droughts are becoming more frequent and more severe. And there are no major new sources …

Guest contributors Maeve Anderson and Mackay Peltzer write that regulatory updates are needed to ensure California’s coastal planning remains consistent with the intent of the Coastal Act.

California’s iconic coastline is simultaneously a source of pride and tension for the state. As increasingly severe storms, intensified by climate change, accelerate the erosion of beaches and bluffs, the conflict around land use at the coast has also intensified.  Nowhere exemplifies this reality better than the City of Pacifica, a popular surfing destination located …

2026: The Year Ahead

Here are six big things to watch.

What to watch for environmentally in 2026: court tests of Trump’s power, midterms, China, grid issues, and state energy moves. In 2025, Trump rolled out new initiatives at a dizzying rate. That story, in one form or another, dominated the news.  This year, much of the news will again be about Trump, but he will have less control of the narrative. Legal and political responses to Trump will play a greater role, as will economic developments. Trump’s anti-environmental crusade could run into strong headwinds.

Thoughts on COP30

On top a deep green background letters read, "COP 30 Brasil Amazonia Belem 2025."

What have we learned about the future of climate negotiations?

we can only expect incremental progress from the U.N. unless or until China takes a leadership role, particularly while the U.S. is also on the sideline.  Incremental progress is better than no progress, obviously. But we’re going to have to look elsewhere for productive international action. 

Basically, that’s going to have to rely on something less than the international consensus that drives COP.  That means doubling down on some other options:  bilateral climate agreements between countries, action by coalitions of interested countries, and subnational agreements including states, provinces, and cities around the world.

Replumbing Los Angeles – Painfully Slowly

An overhead view of a city's layout with a highway, a reservoir, and many houses in sight with mountains in the background.

The City has captured 5.5 billion gallons of stormwater since October 1st — and that is literally just a drop in the bucket.

  This caught my attention last week: The Los Angeles Department of Water and Power says it has captured nearly 5.5 billion gallons of water since Oct. 1 following the recent storms. Mayor Karen Bass’ office announced the estimate on Tuesday, saying it’s enough to serve almost 68,000 homes for an entire year. According to …

The Promise and Growing Pains of Managed Aquifer Recharge

field flooding for recharge

By Dave Owen, Helen E. Dahlke, Andrew T. Fisher, Ellen Bruno, and Michael Kiparsky

  Around the world, groundwater mismanagement is a major driver of water crises. An emerging method for addressing such mismanagement, called managed aquifer recharge, has generated excitement among scholars and water managers. In a newly published article (Owen et al. 2025), we argue that this excitement, while often justified, should also be tempered by acknowledgment …
