Requiem for a Bottom-Feeder
UCLA’s Don Shoup Has Transformed Urban Planning
Every scholar wants to do good, productive, important work, but I suppose all us secretly would like to redefine our fields — to go down in academic history, so to speak. Virtually none of us do. But UCLA’s Don Shoup, who is retiring this year from the Urban Planning department, is one who has. And …

CONTINUE READINGWhat Happens When You Feed Garbage Data to a Nobel Prize Winner? — The Bizarre Story of the Phantom Job Gains from Romney’s Deregulation Plan
Deregulation is one of Romney’s five steps in his plan to add jobs. But how do we supposedly know that deregulation will add jobs? It’s a fascinating story, featuring a Nobel laureate’s economic model. The model is very fancy, lots of complex math, but it’s justified on the basis of data from a discredited study. …
CONTINUE READINGRomney Calls for a Fossil Fuel Feeding Frenzy
The Washington Post reports that Mitt Romney will announce a new energy plan centering on explosive increases in oil and gas development, combined with greater use of coal. I’ve read the staff briefing paper, and the Post’s account is an accurate summary: Mitt Romney on Thursday will outline a plan that he projects would achieve …

From the title, this could be a posting about the election results. It isn’t — although I do wonder whether the relatively rapid changes we’ve seen in the House over the past decade are a sign of increased feedback effects. My topic, however, is climate science. The curve at the left shows how feedback effects …

CONTINUE READINGIt’s All About the Feedback
A fairly common reaction to climate science is to wonder how changes in the concentration of a trace gas can have a substantial effect on the world’s climate. As it turns out, this is exactly the right question to ask. There’s a great post at RealClimate working through the logic. The direct effect of increased …

Feedback effects can lock in decarbonization policies, for better and for worse
This is the fifth in a series of posts. The first post is here. The second post is here. The third post is here. The fourth post is here. Decarbonization is a long-term challenge, and it requires commitments to drive the investments required for innovation and deployment of non-fossil-fuel energy sources. But long-term commitments, which …

How can we enact policy that is effective, resilient, and expands its ambition over time?
Climate change is a difficult problem to solve, politically. The costs of addressing climate change are born by current generations, but the benefits accrue to many generations to come. Addressing climate change might require people today to make significant sacrifices to benefit people around the world, as well as future generations. There are significant, powerful …

California’s Low Carbon Fuel Standard has been successful. CARB should update the program without undermining its fundamental features.
On November 8, the California Air Resources Board, or CARB, is slated to consider approving amendments to California’s Low Carbon Fuel Standard. The program has been so successful in replacing high carbon petroleum-based fuels with lower emissions vehicle fuels that interest groups from all sides of the political spectrum have come forward to demand radical …

CONTINUE READINGModel Uncertainty in Politics and Climate Policy
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.
