The 2024 Election Outcome Could Boost the Case for Geoengineering
A Trump victory would increase the odds that we will ultimately need to start blocking solar radiation as a last resort to limit climate change.
A Trump victory would increase the odds that we will eventually need to “break the glass and pull the red lever.” To be prepared for that possibility, we would also need to do more in the short term to research various forms of geoengineering, their feasibility, and their potential side effects. Basically, if you decide you’re going to start smoking a lot more cigarettes, you need to be prepared for the greater likelihood you’ll need chemo.

The polls could be systematically off, not just due to random error. That’s a worry with climate models as well.
Yes, your favored candidate could sweep the swing states, and yes, climate change could be more moderate than we now expect. But that shouldn’t give you much comfort on either issue, since the errors could equally be in the opposite directions.
Obviously, we’d like to improve our models, but that’s not always easy. In the meantime, the smart thing is to plan on the basis of the best models we have but avoid overconfidence about our predictions.

Here’s the case for setting aside a day to think about climate change, and why that day should be Aug. 23
Creating National Climate Awareness Day would send a message about the importance of climate change. It would also provide an occasion to educate Americans about the issue. If it can also celebrate modern science, and the contributions of women to science, all the better. And all it would take is a Presidential proclamation.

The abortion pill case could undermine the authority of agency’s expert judgments.
The Chevron doctrine requires judges to defer to an agency’s interpretation of a statute if that interpretation is reasonable. The State Farm case, which is much less widely known, requires courts to defer to an agency’s expert judgment unless its reasoning has ignored contrary evidence or has a logical hole. As you probably already know, …

CONTINUE READINGThe New Particulate Standard and the Courts
The tough new air quality standard is sure to be challenged in court. Winning the challenges will be tougher.
EPA has just issued a rule tightening the air quality standard for PM2.5 — the tiny particles most dangerous to health — from an annual average of 12 μg/m³ (micrograms per cubic meter) down to 9 μg/m³. EPA estimates that, by the time the rule goes into effect in 2032, it will avoid 4500 premature …

Bluntly speaking, the statute is a mess.
When the 2023 amendments to NEPA passed as part of the debt ceiling bill, I wrote a series of blog posts about the drafting errors. It turns out that I missed some, as I discovered when working on the new edition of my environmental law casebook. They really aren’t all that subtle, and it’s hard …

CONTINUE READINGCan We Use Regulation to Reduce Inequality?
Contrary to some, I think the answer is yes. And here’s how we can do it.
Inequality is a burning issue in our society but plays only a limited role in the design of regulations. In an article that came out a week ago, I try to work through questions about how economic and racial inequality can be integrated into rule-making. In terms of economic inequality, the current system already has …

Herein of the now-forgotten woman who discovered the warming effect of CO2.
The first climate science ever published was in 1856 by Eunice Newton Foote, who discovered that CO2 and water vapor trapped the sun’s heat. Her paper was read at the annual meeting of the American Association for the Advancement of Science. That paper, along with another paper of hers, were the only physics papers by …

Organizing Universities Around Sustainability
In May, Stanford grabbed headlines by announcing a billion dollar gift to launch a new School of Sustainability. There hasn’t been much written about the details of Stanford’s effort, or about what other schools are doing along similar lines. There’s little in the way of systematic information, but there does seem to be a lot …

CONTINUE READINGThe Revolution, the Enlightenment and the Climate Crisis
The Founding Era’s belief in facts and science has too often been replaced with political identity as a test of truth.
The Declaration of Independence is a document deeply rooted in the Enlightenment. The Declaration begins with a note of cosmopolitanism, referring to “a decent respect to the opinions of mankind.” There is then the famous passage declaring “these truths to be self-evident, that all men are created equal, that they are endowed by their Creator …
