Policy 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.

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.

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 …

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 …

CONTINUE READINGDoes Federal Law Still Preempt State Standards Relating to Fuel Efficiency?
The answer may depend on what being “in effect” means.
If a tree falls in the forest but no one hears it, does it still make a sound? If a law hasn’t been formally repealed but can be violated with complete impunity, is it still in effect? This matters because federal law preempts state fuel efficiency standards if, but only if, a federal standard is “in effect.” Congress just eliminated any penalty for violating the federqal standards. Which means at best they have only a kind of ghostly existence, but no substance to speak of.
CONTINUE READINGThe Trump Governance Playbook, in War and Peace
Going to war is very different than regulating pollutants, but the Trump Administration approaches both decisions similarly.
Trump’s approach to governance has some roots in previous practice, but it is not what Americans generally have been used to. It is a governance style that centralizes power not only within the executive branch, but in the executive branch at the expense of Congress, and in government rather than the public. Some might argue that this is more democratic since only the President is nationally elected. Others take a different view. There’s no question, however, that the governance system is in a very different mode of operation in all spheres, foreign and domestic.

Second in a series of posts outlining key challenges and opportunities facing California’s next governor.
Skyrocketing electricity costs pose a formidable political and economic barrier as California pushes to decarbonize its power supply and electrify homes and transportation. The stakes for the incoming governor are incredibly high: average residential rates for large investor-owned utilities (IOUs) increased 8%-10% annually over the last decade, far outpacing the 3.5% inflation rate. While the …
