The Shadow Price of Carbon
Merging Cost-Benefit Analysis and Feasibility Analysis
The U.S. government has devoted a lot of time and effort to estimating the social cost of carbon. This is basically a standard exercise in cost-benefit analysis, following a familiar three-step process: 1. Impacts. Figure out the physical impacts of the emissions. This involves setting up some emissions scenarios and then running computer simulations to …

CONTINUE READINGCan We Trust the Science? The Challenge of Irreproducible Results
In the peer review process, articles submitted to scientific journals are sent to experts in the field who then assess the methodology, results and conclusions. Based on their feedback, authors often revise and re-submit, publishing an improved article as a result. Peer reviewers rarely attempt the actual experiments described in the paper. Irreproducible results are …

Will This Litigation Be More Successful Than Earlier, Related “Atmospheric Trust” Lawsuits?
Late last week, attorneys representing children from around the nation filed a provocative new lawsuit in federal court, arguing that the Obama Administration is violating the children’s constitutional rights by not taking far more dramatic steps to curb greenhouse gas emissions and address climate change concerns. The newly-filed complaint in the lawsuit, Juliana ex rel. …

Justices Hold CSU Can’t Pass the Buck re: Environmental Mitigation Measures Tied to Campus Expansion
In an important decision issued last week, the California Supreme Court forcefully rejected the California State University’s efforts to avoid paying for mitigation measures needed to offset the adverse environmental impacts associated with CSU’s ambitious expansion plans. That’s welcome if predictable news from a court that has in recent years been protective of the state’s bedrock …

Brown’s National & International Environmental Reputation Disputed by Some California Environmentalists
California Governor Jerry Brown has had a most eventful 2015, especially when it comes to environmental policy. He started the year fresh from an overwhelming election victory last November, earning him an unprecedented fourth term as California’s chief executive. Brown began 2015 by declaring a state drought emergency and becoming California’s “educator-in-chief,” repeatedly warning state …

Tomorrow’s Emission Determine Today’s Social Cost of Carbon
Here’s the weird thing: the social cost of carbon today, depends significantly on the year-by-year emissions of carbon in the future, which we obviously don’t know. (Because it depends on our own future actions!) It takes some explanation to show why that’s true and how it matters. If you know a bit about climate policy, you know …

State Farmers Planting New Almond Orchards Despite Critical Water Shortages
Traveling through California’s drought-striken San Joaquin Valley repeatedly over the past year, I’ve been surprised and disheartened to see that Valley farmers continue to convert their agricultural fields to newly-planted almond orchards. (My anecdotal observations have been confirmed by various recent press accounts.) This development is a striking, current example of Garrett Hardin’s Tragedy of …

A new article suggests river corridors could leverage existing policies to build habitat connectivity
As we try to protect biological diversity for the future, a perpetual challenge is ensuring that the strategies we adopt today will continue to work in the face of changing conditions. How can we design conservation approaches that will be resilient in the face of environmental challenges that will only become more severe in coming years? …

In Michigan v. EPA, the majority followed its own policy views, not those in the statute.
The majority opinion by Justice Scalia has gotten most of the attention. Most notably, he wrote that “[o]ne would not say that it is even rational, never mind “appropriate”, to impose billions of dollars in economic costs for a few dollars in health or environmental benefits.” Indeed, “[n]o regulation is ‘appropriate’ if it does significantly …

New expert report offers recommendations for shoreline armoring management
As California’s beach goers and residents well know, erosion and climate change are already impacting the California coastline. Eighty percent of California’s coast is actively eroding, and the latest science projects that sea levels may rise up to 5 additional feet along much of the coast by the end of this century. Higher sea levels …
