Hot off the Press: The New IPCC Report
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 …

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 …

CONTINUE READINGThe problem with “follow the science”
Science is necessary, but not sufficient, for good policymaking
In the wake of the poor performance of the Trump Administration’s efforts to address the coronavirus pandemic in the United States, there has been advice that the Biden Administration should “follow the science” in developing its coronavirus policies and strategies. While an emphasis on a clean break from the prior Administration’s rejection of the nature …

CONTINUE READINGThe Danger of Climate Change Deadlines
Essential targets set by some of the world’s leading climate scientists and policymakers just passed. Now what?
Seven prominent figures in the global climate change policy discourse published an opinion essay in Nature. In “Three years to safeguard our climate,” they set a deadline for key targets to be met in order to stay on track to meet the Paris Agreement’s global warming goals. The notable thing is that the essay was …

Eyeballing trends in the epidemic? Proceed with caution!
Many of us anxiously scan coronavirus statistics, looking at trends and cross-country comparisons. Warning: We need to be cautious in interpreting those numbers. There’s lots of noise in the data, meaning that it’s not always an accurate measure of what we want to know about the disease. Even death counts are not always reliable — …

CONTINUE READINGDebate Amid Coronavirus: Are Single-Use Plastic Bags Safer?
How Plastics Companies and Environmental Groups Can Help Us Find an Answer
Since the outbreak of COVID-19, concerns have grown over the safety of grocery bags. Many U.S. states—among them New York, California, Maine, Massachusetts, and Oregon—have suspended or delayed their single-use plastic bag bans in the past two months. Some places like Massachusetts, New Hampshire, and San Francisco have gone even further to temporarily ban reusable …
