Some economic models of climate change come out with low damages because they assume smooth and effective adaptation efforts. That never made much sense. There’s a lot of inertia in social systems, and planning major projects can take a long time. Some of what we’re seeing lately is worse than that, however. We’re seeing cases […]
Strolling west on Calle Loiza from the Ocean Park neighborhood of San Juan, Puerto Rico, you could miss the devastation wrought by Hurricane Maria last September. Here in early May 2018, runners and walkers lap the track at Parque Barbosa while middle-aged men try to keep pace with younger guys on the sheltered basketball court. […]
Puerto Rico was hit much harder than Houston. But help was much slower coming.
Texas and Puerto Rico both got hit very hard last year by major hurricanes. But the federal government moved a lot more quickly to get help to Texas. In a new paper, I document the difference and explore the reasons. Although I won’t go into all the details here, this is a situation people need […]
The journalists are sure about the 2018 hurricane season. The scientists? Not so much.
I’m actually in Puerto Rico today for a conference on the situation here after Hurricane Maria. Since hurricanes are on my mind, I wondered what the forecast for this year looks like. As it turns out, the headlines give significantly different takes on what to expect. Here is a sample of news stories, all issued […]
It’s been eight months. What’s happened since the storm?
Hurricane Harvey made landfall in the U.S. on August 25, 2017. That probably seems like ancient history to many Americans who live outside the area. The storm has certainly dropped out of the national media. It’s not easy to find information about how storm recovery is proceeding. But here’s where I could find. Let’s start […]
The Anthropocene will produce profound economic, social, and political effects on human societies
In my prior post, I explained how humans are increasingly altering or influencing natural systems at a planetary level, and not just through climate change. Now I want to explain a little about the impacts of those changes on human societies, and the implications of those impacts for how we will respond as societies to […]
Michael Wara posted previously about Rick Perry’s proposal to subsidize coal and nuclear. In its current incarnation, the proposal is aimed purely at ISOs and RTOs that operate capacity markets, which largely means a single entity, PJM. Why the focus on PJM? Oh, I guess I had better explain. OK, to start with, what did […]
We’re slowing improving disaster resilience. But there have been some notable setbacks.
An ounce of prevention is worth a pound of cure, as the saying goes. The same is true for disasters. We are slowly getting better at mitigating disaster risks. These improvements don’t generally take the form of dramatic breakthroughs. Rather they involve incremental progress on a number of fronts. For instance, homes that were constructed […]
States (for wind) and the Feds (for water) provide insurance for hurricane victims. Here’s how.
Rebuilding takes money. That makes insurance a crucial part of the equation. Insured losses are expected to be in the $70 billion range for Harvey and Irma combined. This includes commercial insurance, but the payments for home owners will also be hefty. Those costs are generally covered by government-supported insurance markets. I’ve posted previously about […]
The 100-year flood and the 500-year flood are both very rough estimates.
My title is a little unfair. So far as I can tell, the people who are trying to figure out the 100-year or 500-year floods in various places are hard-working professionals, applying their expertise to a difficult problem. But there are a lot of uncertainties that get concealed behind the final numbers. The consequence is […]
