The Europeans took a stand but struggled to build a coalition to push for more climate action at this year’s U.N. summit.

The Trump administration has made it tougher for local regulators to reduce truck emissions. Some see warehouse rules as a work-around.

A new study estimates that the deadly 2003 heat wave would cause up to 32,000 deaths each week under 3 degrees Celsius of warming.

John Bel Edwards and the Environmental Defense Fund say lawsuits seeking money to restore the coastline should be heard in state courts.

Annalena Baerbock pointed to droughts and other damage from climate extremes in places such as Chad, Syria and Iraq.

The move would channel more funds to developing countries as traditional climate aid wanes.

Most of the money dedicated to fighting climate change goes to causes other than agriculture, which accounts for a third of emissions.

Some farmers and residents of rural areas say they now fear for their livelihoods and, in some cases, their safety.

Interactions between climate change and antimicrobial resistance across terrestrial, aquatic and health systems reveal shared drivers, synergies and trade-offs that shape health and environmental outcomes. This Comment outlines a solutions-oriented research agenda to advance evidence and action that addresses climate change and antimicrobial resistance as interconnected issues.

The authors theoretically delineate the maximal increases in tree growth that can be expected from increases in plant intrinsic water-use efficiency, which increases with rising CO2. They highlight environmental and physiological limits on growth in the context of experimental data.

Delegates from nearly 200 nations — not including the U.S. — showed they could make some progress. But they deferred the hardest decisions.

Nearly two weeks of talks in the Amazon ended with commitments to do more, but no firm movement on the most divisive issues — including turning away from fossil fuels.

The final text of a proposed deal would be a disappointment for European countries and low-lying Pacific island nations.

One of our favorite—and most important—things that we do at EFF is to work toward a better future. It can be easy to get caught up in all the crazy things that are happening in the moment, especially with the fires that need to be put out. But it’s just as important to keep our eyes on new technologies, how they are impacting digital rights, and how we can ensure that our rights and freedoms expand over time.

That's why EFF is excited to spotlight two free book events this December that look ahead, providing insight on how to build this better future. Featuring EFF’s Executive Director Cindy Cohn, we’ll be exploring how stories, technology, and policy shape the world around us. Here’s how you can join us this year and learn more about next year’s events:

Exploring Progressive Social Change at The Booksmith - We Will Rise Again 

December 2 | 7:00 PM Pacific Time | The Booksmith, San Francisco 

We’re celebrating the release of We Will Rise Again, a new anthology of speculative stories from writers across the world, including Cindy Cohn, Annalee Newitz, Charlie Jane Anders, Reo Eveleth, Andrea Dehlendorf, and Vida Jame. This collection explores topics ranging from disability justice and environmental activism to community care and collective worldbuilding to offer tools for organizing, interrogating the status quo, and a blueprint for building a better world.

Join Cindy Cohn and her fellow panelists at this event to learn how speculative fiction helps us think critically about technology, civil liberties, and the kind of world we want to create. We hope to see some familiar faces there!

AI, Politics, and the Future of Democracy - Rewiring Democracy

December 3 | 6:00 PM Pacific Time | Virtual

We’re also geared up to join an online discussion with EFF Board Member Bruce Schneier and Nathan E. Sanders about their new book, Rewiring Democracy: How AI Will Transform Our Politics, Government, and Citizenship. In this time when AI is taking up every conversation—from generative AI tools to algorithmic decision-making in government—this book cuts through the hype to examine the ways that the technology is transforming every aspect of democracy, for good and bad. 

Cindy Cohn will join Schneier and Sanders for a forward-looking conversation about what’s possible, and what’s at stake, as AI weaves itself into our governments and how to steer it in the right direction. We’ll see you online for this one!

It’s been a month since Rewiring Democracy: How AI Will Transform Our Politics, Government, and Citizenship was published. From what we know, sales are good.

Some of the book’s forty-three chapters are available online: chapters 2, 12, 28, 34, 38, and 41.

We need more reviews—six on Amazon is not enough, and no one has yet posted a viral TikTok review. One review was published in Nature and another on the RSA Conference website, but more would be better. If you’ve read the book, please leave a review somewhere.

My coauthor and I have been doing all sort of book events, both online and in person. This ...

A California judge ordered the end of a dragnet law enforcement program that surveilled the electrical smart meter data of thousands of Sacramento residents.

The Sacramento County Superior Court ruled that the surveillance program run by the Sacramento Municipal Utility District (SMUD) and police violated a state privacy statute, which bars the disclosure of residents’ electrical usage data with narrow exceptions. For more than a decade, SMUD coordinated with the Sacramento Police Department and other law enforcement agencies to sift through the granular smart meter data of residents without suspicion to find evidence of cannabis growing.

EFF and its co-counsel represent three petitioners in the case: the Asian American Liberation Network, Khurshid Khoja, and Alfonso Nguyen. They argued that the program created a host of privacy harms—including criminalizing innocent people, creating menacing encounters with law enforcement, and disproportionately harming the Asian community.

The court ruled that the challenged surveillance program was not part of any traditional law enforcement investigation. Investigations happen when police try to solve particular crimes and identify particular suspects. The dragnet that turned all 650,000 SMUD customers into suspects was not an investigation.

“[T]he process of making regular requests for all customer information in numerous city zip codes, in the hopes of identifying evidence that could possibly be evidence of illegal activity, without any report or other evidence to suggest that such a crime may have occurred, is not an ongoing investigation,” the court ruled, finding that SMUD violated its “obligations of confidentiality” under a data privacy statute.

Granular electrical usage data can reveal intimate details inside the home—including when you go to sleep, when you take a shower, when you are away, and other personal habits and demographics.

The dragnet turned 650,000 SMUD customers into suspects.

In creating and running the dragnet surveillance program, according to the court, SMUD and police “developed a relationship beyond that of utility provider and law enforcement.” Multiple times a year, the police asked SMUD to search its entire database of 650,000 customers to identify people who used a large amount of monthly electricity and to analyze granular 1-hour electrical usage data to identify residents with certain electricity “consumption patterns.” SMUD passed on more than 33,000 tips about supposedly “high” usage households to police.

While this is a victory, the Court unfortunately dismissed an alternate claim that the program violated the California Constitution’s search and seizure clause. We disagree with the court’s reasoning, which misapprehends the crux of the problem: At the behest of law enforcement, SMUD searches granular smart meter data and provides insights to law enforcement based on that granular data.

Going forward, public utilities throughout California should understand that they cannot disclose customers’ electricity data to law enforcement without any “evidence to support a suspicion” that a particular crime occurred.

EFF, along with Monty Agarwal of the law firm Vallejo, Antolin, Agarwal, Kanter LLP, brought and argued the case on behalf of Petitioners.

From Anthropic:

In mid-September 2025, we detected suspicious activity that later investigation determined to be a highly sophisticated espionage campaign. The attackers used AI’s “agentic” capabilities to an unprecedented degree­—using AI not just as an advisor, but to execute the cyberattacks themselves.

The threat actor—­whom we assess with high confidence was a Chinese state-sponsored group—­manipulated our Claude Code tool into attempting infiltration into roughly thirty global targets and succeeded in a small number of cases. The operation targeted large tech companies, financial institutions, chemical manufacturing companies, and government agencies. We believe this is the first documented case of a large-scale cyberattack executed without substantial human intervention...

Policyholder-owned insurance exchanges are filling voids left by traditional insurers. But some are low on cash to pay excessive claims.

“Good fortune” with a lack of catastrophes helps seven major insurers earn more than $1 billion in underwriting, new analysis finds.
