Dear UNFCCC, Subnational Governments are Key to Protecting Forests
GCF Task Force and Regions4 Submit Comments to COP30 Roadmap on Halting and Reversing Deforestation and Forest Degradation by 2030
Two of the world’s largest subnational governmental networks – the Governors’ Climate and Forests Task Force (GCF Task Force, a project of the Emmett Institute on Climate Change and the Environment at UCLA School of Law), and Regions4 – submitted a comment letter today providing input to the Roadmap on Halting and Reversing Deforestation and …

The Iran War it is hitting energy markets hard. Will that affect the energy transition?
The Iran War has been a big shock to the global energy system. It’s natural to wonder what the long terms will be. What it will lead to an orgy of oil and gas drilling, or will it speed up the energy transition? There are enormous uncertainties, and making confident predictions would be a clear mistake. In this post, I’ll try to unpack some of the issues and offer a semi-educated gas about the answers.
Climate Issues in the 2026 Governor’s Race: Housing and Climate
Fifth in a series of posts outlining key challenges and opportunities facing California’s next governor.
(This climate issue brief is authored by CLEE’s partners at the Terner Center for Housing Innovation.) California faces complex and integrated challenges of unaffordable housing and climate change. Failure to build adequate housing supply has resulted in high prices that have pushed home buyers and renters to locations that are further from jobs, schools, and …

CONTINUE READINGPolicy Implications of Accelerating Warming
If warming is coming more quickly, we need to pick up the pace on policy responses.
There seems to be an emerging scientific consensus that the rate of global warming is rising. After screening out the effects of natural factors like El Niño, scientists have concluded that the pace of warming has roughly doubled since the 1970s. What does this tell us about policy? Some of the implications are more obvious than others, and at least one implication may be unsettling for some climate advocates. Most obviously, we need to accelerate our efforts to carbon emissions. We will be closing in on possible tipping points faster than expected. Climate impacts that we might have expected twenty years from now could hit in half that time.
CONTINUE READINGThe Environment is a System, Not an Array.
In 1969, Barry Commoner summed up much of environmental science in six words. Today’s conservatives don’t get it.
People have an intuitive tendency to focus on an action’s immediate direct effects. The same intuition leads us to downplay effects that are indirect, long-range, and cumulative. This can lead us astray, as it has the Supreme Court, when dealing with impacts on environmental systems. Writing at the outset of the modern environmental world, biologist Barry Commoner tried to crystalize what was known about the environment into four crisply phrased laws. The first law read simply: “Everything is connected to everything else.” What we have learned since Commoner published The Closing Circle in 1969 has only confirmed that insight.
This interconnected means that the environment is a system (really, a nested set of systems), where interactions are paramount. It’s not just an array of different things happening independently in different places or times. That’s true, as we’ve learned, not only of the environment but the global economy to which it is linked and of the geopolitical realm linked to that.
CONTINUE READINGWe are Hitting a Major Methane Milestone
The Drain is a weekly roundup of environmental and climate news from Legal Planet.
This year, we celebrate 250 years since its discovery. No, I don’t mean America (though plans are underway to celebrate the semiquincentennial this July.) I’m talking about methane — that colorless, odorless, flammable and short-lived but super potent greenhouse gas that is helping heat the planet faster than carbon dioxide. It was 250 years ago …

Fourth in a series of posts outlining key challenges and opportunities facing California’s next governor.
(This climate issue brief is authored by CLEE’s partners at the Building Decarbonization Coalition and Caliber Strategies.) As California pushes to decarbonize, its homes and commercial buildings are a central driver of the state’s affordability, energy and infrastructure challenges. Building energy consumption (both electricity to power appliances and gas to power furnaces and stoves) is …
CONTINUE READINGEarth is Getting Darker. Here’s Why That’s Alarming
Some climate scientists are calling attention to yet another alarming recent climate trend: Earth’s declining reflectivity and what it may mean for feedback effects on future warming.
Some recent Earth observations are spreading new alarm among climate scientists. The observations have been reported in many scientific and environmental outlets, and have provoked a fair amount of confusion and some misrepresentation. Some scientists have been informally calling these observations “the most important climate risk you’ve never heard of.” But they have not yet …

The real lesson everyone misses about Paul Ehrlich and his famous wager.
Paul Ehrlich died last weekend at the age of 93. Among scientists, he was celebrated for his work on population biology, integrating economics and ecology, and for his creation (with Peter Raven) of the field of co-evolution, the study of how species influence each other’s evolution. To the public, he was much better known as …

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 …
