Better late than never.

I had a great time discussing with Christophe Courchesne of the Hothouse Earth Podcast my book with Brigham Daniels, Lessons for a Warming Planet (lnkd.in/gKDAXM-m). The episode just dropped! I hope you check it out.

The US Constitution and laws do not protect oil companies from being sued over the harm they cause to the climate theconversation.com/the-us-const...

Judges in Oregon and Hawaii have affirmed what experts in environmental law and federalism have already been saying: that the appropriate place to sue for damages from oil companies is in the state courts. Now, the Supreme Court must follow their lead when they decide Suncor.

Great to have this conversation with my colleague Rachel from the center for progressive reform about our new book with Brigham Daniels. Thanks, Rachel! Please check it out.

I enjoyed this conversation, hopefully you take a look and find it useful also.

Who is responsible for California's toxic borderland river? I give my thoughts in this news article. www.sfgate.com/bayarea/arti...

Gov. Newsom is ignoring his critics, and has called a declaration of a state of emergency "symbolism." Is he right? It's true the Trump admin may not be responsive, but as CPR's @alejandrocamacho.bsky.social tells @sfgate.com, a declaration could still create political leverage and expedite action.

Glad to participate in this conversation with Avigail at No Jargon that ties my new book on the history US environmental law with Brigham Daniels with more recent events.

Please check out this Earth Day episode of the wonderful LENS podcast, where I discuss US environmental history and my book, which also dropped today! www.ioes.ucla.edu/lens/podcasts/

"I understand the despair. But having studied all of our environmental legal history, we have found that the invisible undercurrents of today become the dominant waves of tomorrow." - @alejandrocamacho.bsky.social on how writing a history of environmental law revealed paths to a greener future.

Happy Earth Day! Professors @brigdaniels.bsky.social and @alejandrocamacho.bsky.social's book "Lessons for a Warming Planet: A Vital History of U.S. Environmental Law" is out now from @nyupress.bsky.social. Learn more: nyupress.org/978147980285...

The first #EarthDay succeeded because of a decade of preparatory work. Here are the lessons for us in 2026. A powerful read from @alejandrocamacho.bsky.social @uclalawemmett.bsky.social. legal-planet.org/2026/04/22/o...

This Earth Day, please consider buying our new book on how the US can learn from where we have been!

This Earth Day, please consider sharing this brief illustrated timeline on US environmental law history with anyone (kids included!) who might like (or need!) a snapshot of how the US can learn from where we have been! And consider buying the book!

Lessons for a Warming Planet: UCLA’s Alejandro Camacho discusses his new book and the lessons we can learn from prior generations of environmental advocates. @alejandrocamacho.bsky.social @uclalawemmett.bsky.social legal-planet.org/2026/04/14/l...

Here’s a Q&A on my forthcoming book, already available digitally and out in bookstores this Earth Day eve April 21!

Foreword Reviews offers early acclaim for "Lessons for a Warming Planet." "Addressing environmental damages caused by climate change and artificial intelligence, among other challenges, Lessons for a Warming Planet is a thorough survey of environmental legislation throughout US history."

For many this may be lost in the shuffle of terrible actions. This is just petulant spite. The American people should not subsidize fossil fuels at $1 billion to stop safe renewable energy. It’s an unbelievable waste of money, forced on the American people, arbitrary & capricious, & deeply immoral.

I'm excited that Lessons for a Warming Planet: A Vital History of US Environmental Law, co-written with Professor Brigham Daniels, will be released on Earth Day Eve, April 21, 2026. Save 30% on pre-orders using code NYUAU.

Tragic but vital work being done at UCLA Law on ICE detention deaths. We all must notice, stand up, and use our power to fight back in our own way.

My latest pub, apparently more controversial than it should. We must support research on whether nonnative coral can fulfill reef-building in the Caribbean. If it shows promise, we should work to allow provisional deployment of such species while monitoring for adverse effects and using precaution.

@alejandrocamacho.bsky.social's (@law.ucla.edu) scholarship studies the goals, structures, and processes of regulation, with a particular focus on natural resources, pollution control, and land use law. Connect with Camacho: scholars.org/scholar/alej...

Unfortunately, Trump‘s biggest attack on climate action. Fortunately, it’s on shaky scientific and legal grounds.

I’ll need to work on it, I’m a decidedly less serious person than I am in this video

🐻 🌲 In this @legal-planet.org op-ed, @alejandrocamacho.bsky.social of @law.ucla.edu warns that the Trump administration's proposed changes to the #EndangeredSpeciesAct threaten to harm species & habitat protections, with consequences for the government and economy. Read today:

So glad to be a part of this new intellectual and social community!

There really isn’t a reasonable interpretation that would allow this road to be built. It’s a brazen attempt to ignore existing public lands and other law just to build a road, when another road could be built that doesn’t do so.

The Trump administration has resurrected several regulatory changes to the Endangered Species Act. They are "as irresponsible as they are illegal," writes our @alejandrocamacho.bsky.social in a new piece at @legal-planet.org. legal-planet.org/2026/01/26/t...

Alejandro Camacho (@alejandrocamacho.bsky.social) has joined us as a professor of law at @law.ucla.edu! The Emmett Institute keeps growing stronger. Read a Q&A with Camacho about his scholarship and policy-relevant advocacy at @legal-planet.org: legal-planet.org/2026/01/22/a...

Really excited to start this new chapter in my career. UCLA Law is amazing and I look forward to joining its community.

Despite current US government’s immoral and economically idiotic efforts to fight it, it is good news that the world is slowly transitioning towards renewable energy. We need it to be further along, and it easily could be. But at least the world is waking up. The US government will be back someday.

Depressingly true

This is not normal. This is not legal. You do not have to be an attorney to know this is dangerous.

California is a place where people are having reasonable debates about climate policy. It’s not easy stuff, adults mostly in good faith are trying to figure it out. If only something even remotely similar was happening at the federal level.

Wonky report but real cause for optimism globally, despite Trump’s completely regressive and idiotic policies on energy. Solar and wind outpaced the growth of global electricity demand in the first half of 2025, vaulting renewables toward overtaking coal worldwide for the first time on record.

UC Faculty please consider signing

This is the moron that is taking down the United States and trying to do likewise to the world. We are under the death grip of the most idiotic cult in the history of the world.

Chancellor’s Prof. @alejandrocamacho.bsky.social, in The Hill, reflects on the long history of U.S. environmental law and warns that recent federal actions could represent significant rollback of protections, with lasting consequences for public health & the environment. thehill.com/opinion/ener...

Unfortunately, Trump has remarkably already won the title of worst president on the environment in the history of the US.

For those struggling with inaction, perhaps this might help.

The Trump admin is blatantly ignoring the overwhelming science to be an international pariah & rewrite reality. No independent moral scientist considers this factually & morally defensible. It’ll be challenged in court & likely will lose. Even the first Trump admin thought this was beyond the pale.

Fox News conservatives reclaiming Nazi as a badge of honor. Glad to see some rare accuracy on that network.

A real post by Trump’s Interior Department using taxpayer dollars for propaganda. It’s horrifying and hilarious. Horrifying because it’s the best evidence we live in an Idiocracy. Hilarious because it looks as if done by a fifth grader and uses a gay anthem promoting helping underprivileged men.

I guess I agree with Elon on something. This would be suicidal. And it’s likely to happen. The Republicans are screwing over INDUSTRY ESPECIALLY IN RED STATES in order to make Trump happy for 5 minutes. BTW the US Chamber of Commerce has said it’s stupid and dont do it also.

A new op-ed by Board Member @alejandrocamacho.bsky.social and Member Scholar Rob Glicksman pushes back on attacks against NEPA. This bedrock law makes government decisions smarter and more democratic, despite what critics say. #ProtectNEPA therevelator.org/nepa-lies-mi...
