Pearl Harbor Today

82 years after the attack, what is the state of the harbor?

Today is Pearl Harbor Day, the anniversary of the Japanese attack that launched the U.S. into World War II.  Those of us who don’t live in Hawaii may not think much about the harbor, but I started to wonder how things were going environmentally there. The geography is more complex than I had expected. I …

Fudging the differences between carbon capture and carbon removal risks weakening climate action

Emissions cuts alone will (almost certainly) not keep the global average temperature rise below 1.5°C. But some optimism remains. Alongside a rapid phase-out of fossil fuels, substantial deployment of carbon dioxide removal (CDR) techniques might avert – or at least limit – overshoot of 1.5°C. At COP 28 this week the US and several partners …

The New Frontier of Methane Regulation 

A climate and weather satellite

Nations, companies, and NGOs are targeting methane like never before using satellite data. A new UCLA paper outlines what that could mean for regulation. 

Methane is ready for its close-up. The first week of COP28, the UN climate talks taking place in Dubai, saw a handful of big announcements about how world leaders plan to tackle human-made climate change by targeting methane, a powerful short-term climate pollutant. The UCLA Emmett Institute is also drawing attention to the issue of …

When Communities Take Over Their Energy Systems

Is Local Control A Good Thing? It’s Complicated . . .

This Post was Co-Authored by Sharon Jacobs and Dave Owen. For many decades, most people in the United States have obtained their electricity from a large investor-owned utility company (IOU). They had no real choice. Much of U.S. energy law was built on the belief that the best way to provide electricity was to give …

Climate Change and the Hard-Headed Realist

Henry Kissinger showed that you don’t have to have a shred of idealism to favor climate action.

It’s not surprising that Bernie Sanders said, rather emphatically, that he was not a friend of Kissinger’s.  Yet there was one issue where they did agree:  climate change. If there was one thing that Henry Kissinger stood for, it was the hard-headed “realist” view of foreign policy — a view that prioritizes national interest at …

Why Do Small Changes in Global Temperature Matter So Much?

One problem is that we’ve pursued optimization rather than robustness.

Scientists are warning us that even comparatively small changes in average temperature may have disastrous results. If you turn up your thermostat 2 ºC (about 3.6 ºF), the difference may be noticeable but it’s no big deal. So why is that a scary increase in global temperatures?  Some reasons are physical, particularly the difference between …

Climate Backlash

Vicious attacks on climate progress are on the rise.

Presumably, no one actually wants rising seas, dangerous heat waves, severe droughts, runaway wildfires, and floods. Nor, I assume, are there many who want those climate disasters for their children and grandchildren. Still, there are all too many politicians and public figures who act as if their goal was to foment climate change. No doubt the …

A Guide to Environmental Law Centers

There are twenty and the list is growing.

Many law schools consider public service a key part of their missions. More than most people appreciate, they play an important role in public policy in areas as diverse as intellectual property, criminal justice, and environmental law. Research centers are an increasingly common institutional setting for that work. With that in mind, I’ve tried to …

Have We Begun the Third Age of Climate Law?

Some thoughts for Environmental History Week.

An international agreement in 1992 committed the world’s nations to addressing climate change but contained few specifics. The US ratified that agreement, but there was little concrete action here through the end of the 20th Century. As this century began, things looked optimistic, with both presidential candidates favoring reductions in carbon emissions.  Promptly after taking …

Evolving Air Quality Standards

The standards have gotten tougher. Compliance still lags.

The goal of the Clean Air Act is to achieve national ambient air quality standards (NAAQS), with the primary requirement being protection of public health. As our understanding of the health effects of air pollution has improved, there has been a general trend toward tightening the standards. However, it’s very hard to keep track of …
