Of War and the Environment
War and environmental disruption are like evil twins, often found together.
A Vietnam-era slogan proclaimed that “war is not healthy for children and other living things.” And war is indeed a danger to the environment. But perhaps less obviously, environmental disruption also makes wars more likely. The slogan was appropriate for its time. The U.S. deforestation campaign in Southeast Asia caused environmental harm on an unprecedented scale. According to WorldWatch, “an estimated 35 percent of southern Vietnam's inland hardwood f...
CONTINUE READINGMaking Key Policy Decisions in Advance of Droughts
Part 6 in a Series on Improving California Water Rights Administration and Oversight for Future Droughts
It’s hard to respond effectively to a crisis when you don’t have clearly defined priorities. This is true for sudden-onset crises, like floods and wildfires, and also for slow-onset crises, like droughts. My recent posts have explored why the State Water Resources Control Board (Board) should develop a contingency-based framework to support its drought decisions and how it might go about doing this. As I’ve flagged previously, complementary efforts to re...
CONTINUE READINGGoverning New Biotechnologies for Biodiversity Conservation
The fourth in a series examines how international institutions have responded
The previous two posts in this series described how and why genetically modified organisms (GMOs) could be introduced into wild populations, either "typically" modified ones that would transmit their altered genes ineffectively or those with "gene drives" whose changes would quickly propagate through the entire population. In both cases, their potential applications include helping conserve biodiversity through making wild populations resistant to disease, increasing the...
CONTINUE READINGThe Governance of Solar Geoengineering: Managing Climate Change in the Anthropocene
My book is now available!
I interrupt my ongoing blog series on new biotechnologies and their governance (1, 2, 3) to announce that my book The Governance of Solar Geoengineering Managing: Climate Change in the Anthropocene is available today from Cambridge University Press. The brief description is: Climate change is among the world's most important problems, and solutions based on emission cuts or adapting to new climates remain elusive. One set of proposals receiving increasing attention ...
CONTINUE READINGEPA’s Magic Disappearance Trick
The Trump EPA has come up with a way to hide hundreds of deaths in plain view.
According to press reports, EPA is preparing to ignore possible deaths caused by concentrations of pollutants occurring below the national ambient air quality standards (NAAQS). This is a key issue in a lot of decisions about pollution reduction. For instance, there is no NAAQS for mercury, but pollution controls on mercury would, as a side benefit, reduce pollution levels of harmful particulates. According to EPA’s prior cost-benefit analyses, those reductions cou...
CONTINUE READINGGenetically Modifying Wild Populations
The third in a series examines powerful new gene drive tools
In my previous two posts, I introduced what I call first, second, and third generation genetically modified organisms: (1) GM bacteria for diverse, mostly indoor purposes; (2) GM crops and agricultural animals; and (3) GMOs that would be intentionally placed into natural environments, where they would live, reproduce, and transmit their modified genes to offspring. A limitation with the final category is that an entire wild population (that is, those organisms within ...
CONTINUE READINGGetting to 2050
A roadmap for achieving an 80% emissions cut.
To do its part in keeping climate change to tolerable levels, the United States needs to cut its carbon emissions at least 80% below 1990 levels by 2050. That’s not just a matter of decarbonizing the electricity sector; it means changes in everything from aviation to steel manufacture, and reducing not only CO2 but also other pollutants like HFCs and black carbon. In a new book, Michael Gerrard and John Dernbach have assembled a team of authors to look at thirty-f...

Will Gov. Newsom and Sen. Atkins Rescue SB 50?
California faces a dual crisis: a massive housing shortage leading to displacement and spiraling economic inequality; and an increase in driving miles and related greenhouse gas emissions which threaten to undermine the state's progress achieving its climate goals. Both of these crises were solidly addressed in Sen. Scott Wiener's SB 50, which seeks to ease local restrictions on housing development near transit and jobs, in part so more residents can access transit and s...
CONTINUE READINGBike Week 2019: Los Angeles Cyclists Dream of Protected Bike Lanes
These are heady days for the soon-to-be-expanded class of Los Angeles commuters who use bicycles (1 percent and growing!) and other non-car modes to navigate our asphalt arcadia. The breathlessness might come from inhaling small particulate and ozone pollution from car exhaust, or it could have to do with new city and county-level goals to rapidly expand the share of trips taken by bike, foot, rail, and e-mobility devices: the scooters and their smartphone-enable...

NIMBYs Win A Battle, But Trench Warfare Continues
The NIMBYs have won a battle: A high-profile bill that would have increased home building near mass transit and in single-family home neighborhoods across California has been killed for the year, ending a major battle over how to address the state’s housing affordability crisis that has attracted attention nationwide. Senate Bill 50 by Sen. Scott Wiener (D-San Francisco) would have required cities to allow four- to five-story apartme...
