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 …

St. Valentine’s Other Assignment

Along with lovers, couples, and marriage, he has a more environmental domain.

St. Valentine is associated with love and romance. He is also the patron saint of beekeepers. It’s unclear why. Maybe it’s the association of honey with happiness and affection, especially in the age before chocolate reached Europe. Or maybe it’s because of the “birds and the bees” as models for explaining sex to children. Whatever …

How California (and the World) Get to 30×30

COP15 in Montreal ended with a pledge to protect 30 percent of the planet by 2030. UCLA student analysis shows what we can learn from California’s own plan.

By Ashley Anderson, Elana Nager, and Madeline Ward As 2022 wound down, the United Nations Biodiversity Conference (COP 15) convened in Montreal. The conference ended with around 190 of the world’s nations adopting the Kunming-Montreal Global Biodiversity Framework, which establishes four goals and twenty-three targets to be achieved by 2030. The most prominent of these …

Scenarios and Uncertainty

Imagining different futures can be the best way to think through options when we don’t know the odds.

In environmental law, we’re often operating at the limits of knowledge about the natural world and human behavior. Climate change is well understood in some ways, but it will set off a chain of reactions that we only partly understand. It’s also difficult to predict the future of ecosystems, future energy prices, technological changes, and …

When is a bee a fish?

The California Court of Appeal finds that invertebrates can be protected under the California Endangered Species Act

That was the question before the Third District of the California Court of Appeal. The California Fish and Game Commission had accepted petitions to list four species of native California bees for protection under the California Endangered Species Act (CESA). A group of agricultural trade associations challenged the decision as exceeding the Commission’s authority …

Reforming the California Endangered Species Act

Updating the state’s landmark biodiversity law for the twenty-first century

California has a rich heritage of biodiversity, with many species found nowhere else in the world (including the iconic giant sequoia trees). But California’s biodiversity faces grave threats – pressures from development that eliminates habitat; water shortages that harm aquatic species in California’s rivers; and climate change impacts that are shifting and altering habitats, among …

Calculating the Extinction Cost of Carbon

Or, how many megatons do we need to cut to prevent one extinction?

Economists often talk about the social cost of carbon, which basically translates the harm done by a ton of CO2 into dollars. The dollar metric is less useful as applied to ecological impacts like species extinctions than impacts of humans. It may be better to skip the dollar conversion, and just ask how much a …

The Kolbert Report

Elizabeth Kolbert’s new book asks what it means to protect nature in the Anthropocene.

Elizabeth Kolbert’s new book, Under a White Sky, opens with the story of the battle to keep invasive Asian carp out of the Great Lakes. The problem exists because of two earlier interventions with nature. A century ago, we reversed the flow of the Chicago river to keep the city’s pollutants out of Lake Michigan …

The Whipsaw Effect

Get ready for a rough ride, with sudden weather reversals and climate shifts.

Steady predictable changes in climate and weather would be easier to adapt to. Instead, we may well see some very sudden shifts, both in terms of short-term weather and longer-term climate regimes.

Deferred Planetary Maintenance

It’s easy to put off long-term problems when there’s a crisis. Much too easy, actually.

Long-term problems get short shrift in a crisis. That’s true of infrastructure repair; it’s also true of climate change. Like deferred maintenance, climate change just gets bigger the longer it’s put off. I often see the fruits of deferred maintenance on the Berkeley campus. Building conditions are a huge problem at Berkeley. Whenever there’s a …
