Cost-Benefit Analysis and Deep Uncertainty
How should agencies take into account “the things we know we don’t know”?
Since 1981, cost-benefit analysis (CBA) has been at the core of the rule making process. OIRA, the so-called “regulatory czar” in the White House, must approve every significant regulation based on a review of its CBA. But CBA has had a major blind spot. It embodies techniques for analyzing possible harmful outcomes when the probability …

CONTINUE READINGArguments over Solar Geoengineering Research
Science Magazine weighs in
Doing research on environmental issues or responses is usually an easy call for policy-makers and gets wide political support, even if there’s disagreement what to do about the issue. But there is now one big exception: research on solar geoengineering (SG). SG would cool the Earth, temporarily and imperfectly offsetting some of the climate effects …

CONTINUE READINGThe Fuss about Methane
Part 1: Science and weird facts
Methane is getting a lot of attention in climate debates. There was even a “Methane Day” last Tuesday at the climate conference in Glasgow. Several new regulations controlling methane emissions have been adopted recently, including two new rules for the US oil and gas sector announced last week. There’s a new informal international agreement to …

CONTINUE READINGCost-Benefit Analysis: FAQs
Cost-benefit analysis has been a key part of the regulatory process since 1980. Here’s how it works.
Cost-benefit analysis is required for all major regulations. It’s also highly controversial, as well as being a mysterious procedure unless you’re an economist. These FAQs will tell you what you need to know about how cost-benefit analysis (CBA) fits into the regulatory process, how it works, and why it’s controversial. Q: Let’s start with a …

The latest science confirms the need for urgent action.
The IPCC issued the massive first volume of its new report on climate change on Monday. This volume focuses on climate science: how much will the world warm, and what will the impacts be? The bottom line is that the evidence is becoming ever firmer that (a) humans are causing an unprecedented rate of climate …

CONTINUE READINGEarth System Interventions for Sustainability
We actively shape major Earth systems, with increasingly powerful technologies. We should face up to it.
Stewart Brand–a contender for the most interesting living person in the world–famously opened the Whole Earth Catalogue in 1969, “We are as gods and might as well get good at it.” Importantly (and often misunderstood), he meant not that we are gods, but instead that technologies have given humanity powers that had previously been exclusive …

CONTINUE READINGSolar Geoengineering and Public Engagement Trolling
A first test of a long-planned outdoor solar geoengineering experiment has been delayed–again. Why?
It has been a busy week in solar geoengineering. Last week, the US National Academies released a report that offers recommendations for a research program and for governance of research. (A few of us will post our thoughts on the report here soon.) Here I discuss developments regarding outdoor solar geoengineering experiments, of which there have …

Do regulators and utility managers have irreconcilable differences or mutual goals? By Alida Cantor, Luke Sherman, Anita Milman, and Mike Kiparsky. What do climate change, aging infrastructure, and urban population growth have in common? They all pose major challenges – especially for water infrastructure in the United States. And many utilities are having a …

Technical policy questions often involve ethical political questions that the public must have a say in
As vaccination for the coronavirus in the United States ramps up, I want to take a look back to a policy dispute over the initial plans for vaccine distribution at the end of 2020 and the beginning of 2021 – in part because that fight (like “follow the science,” which I blogged about recently) also …

CONTINUE READING“NIABYs” Obstruct Important Climate Change Research
Some activists say “not in my backyard,” but strident opponents of solar geoengineering argue “not in anyone’s backyard.”
A peculiar type of activism is manifesting with regard to solar geoengineering. This proposed set of technologies to reduce climate change has been subject to only a few outdoor experiments. One has been in the pipeline for almost a decade: The Stratospheric Controlled Perturbation Experiment (SCoPEx) would involve the launch of a balloon into the …
