Don’t Believe Everything That You Read

CNN solar geoengineering tweet

Solar geoengineering is often inaccurately portrayed in the media

If you had followed the climate change news over the weekend, you might have been shocked to see headlines such as “Scientists Prescribe a Healthy Dose of Sulphate Particles to Promote Global Cooling on the Cheap.” CNN tweeted that “Harvard and Yale scientists are proposing that we tackle climate change by dimming the sun.” And …

New Book Demonstrates the Hidden History of Climate Science

It’s a great regret of mine that I did not study the history of science either as an undergraduate or in graduate school. Then, it seemed to me like an arcane, recondite field — almost bizarre. Boy, was I wrong. Now in my rapidly advancing dotage, I recognize how it touches on so many of …

Another Possible Means To Keep Global Warming Within 1.5 Degrees Celsius

Did the IPCC bury the lede regarding solar geoengineering?

In my previous posts on the reports of the Intergovernmental Panel on Climate Change (IPCC), I described how models assume the use of uncertain negative emissions technologies at very large — if not impossible — scales in order to keep global warming within 1.5 or two degrees Celsius (1, 2; see also my colleague Julia …

Negative Emissions Technologies in the New Report on Limiting Global Warming

Cover of IPCC's special report on 1.5°C warming

The new Intergovernmental Panel on Climate Change report on 1.5°C warming relies heavily on negative emissions technologies.

Last week, I described how the scenarios expected to keep global warming within the 2°C target, which was internationally endorsed in the Paris Agreement, had to assume the use of negative emissions technologies at very large scales. The Intergovernmental Panel on Climate Change (IPCC), an international assessment body, downplayed this essential fact in its most recent major report, …

A Major Challenge for Avoiding Climate Change Hides In Plain Sight

Bio-energy with carbon capture and storage

If we probably cannot keep global warming within agreed-upon limits by reducing emissions alone, how could we?

Next week, the international body responsible for assessing climate change will release a special report on the 1.5°C target, an ambitious, international goal to limit global warming that became part of the Paris Agreement in 2015. The report might mark a significant turning point for how policy makers, the scientific community, and others think about …

The Endangered Species Act in the Supreme Court: Oral Argument Today in Weyerhaeuser v. US Fish & Wildlife Service

Post-Argument Panel at Georgetown Law Will Feature Advocates

Oral argument in Weyerhaeuser v. U.S, Fish & Wildlife Service is this morning, the first day (and first argument) of the new Supreme Court term. The Court will be short-handed, with only eight Justices hearing the case.  I’ll be attending the argument and speaking on a post-argument panel at Georgetown Law School, along with other advocates …

When No News Would Be Good News: The Ongoing Trials of Prop 65

California’s Proposition 65 law has been consistently making the news lately — but not for the reasons it should.

This summer, California’s unique-in-the-nation law governing human exposure to toxic chemicals, Proposition 65, has been consistently making Page 1 — but in ways that belie the adage that “all publicity is good publicity.” Most heavily reported, and acutely politically perilous to the law’s supporters, has been a state trial court ruling that coffee must bear …

Awaiting the Climate Change “Trial of the Century”

Juliana v. U.S. “Atmospheric Trust” Federal Trial Set to Begin in October

The Trump Administration really, really doesn’t want the Juliana v. United States case, a.k.a. the “atmospheric trust litigation,” to go to trial. But despite the persistent efforts of President Trump’s Justice Department to have the Juliana case dismissed, it now appears that the most important currently-pending climate change case in the nation will indeed go to trial …

UCLA Law Wells Environmental Law Clinic Files U.S. Supreme Court Brief on Behalf of Scientists in Endangered Species Act Case

Scientists’ Brief Argues Federal Agencies and Courts Must Use Science in Interpreting “Habitat” Under the Endangered Species Act; Clinic Clients Include Profs. Stuart Pimm & E.O. Wilson, Along With Three MacArthur “Genius” Award Recipients & Ten Other Esteemed Scientists

Congress enacted the Endangered Species Act in 1973 to protect species at risk of extinction.  Congress viewed species extinction as an urgent threat requiring urgent, decisive action.  The result was a bipartisan law designed to apply scientific knowledge and expertise to managing the threats to U.S. species.  While the Act has been controversial, and characterized …

The Hurricane Outlook

The journalists are sure about the 2018 hurricane season. The scientists? Not so much.

I’m actually in Puerto Rico today for a conference on the situation here after Hurricane Maria. Since hurricanes are on my mind, I wondered what the forecast for this year looks like. As it turns out, the headlines give significantly different takes on what to expect. Here is a sample of news stories, all issued …
