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 […]
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 […]
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, […]
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 […]
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 […]
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 […]
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 […]
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 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 […]
Personal Reflections on the Raging Debate Over Trump’s Utah Monument Reductions
One of most highly visible disputes arising out of the Trump Administration’s multifaceted efforts to roll back and nullify the natural resources policies of previous administrations is the decision by President Trump and Secretary of the Interior Zinke to substantially reduce two national monuments in Utah created by former President Obama under the Antiquities Act. President Trump’s December […]
