These states could suffer the most without FEMA
Some of the most disaster-prone states would face the greatest financial burdens with less federal relief assistance.

The politics of disaster relief suggest that the current admin will have considerable trouble dismantling FEMA. Data from our Disaster Dollar Database shows why: climate-vulnerable red states would be hurt most.
Trump’s talking about shutting down FEMA. Republicans hate that idea.
GOP lawmakers resisted the president's suggestion FEMA might need to "go away," but they support changes to the disaster response agency.

Reading this EO, it feels like this new FEMA review council is being strongly nudged toward a pre-cooked conclusion: the costs and responsibilities of disaster aid should be pushed down to the states and away from the federal gov’t.

Investors' attention span for physical climate risk buried in municipal bonds is limited, and so local investment in adaptation may be being squelched. Maybe limiting the federal tax exemption would focus things - post today: open.substack.com/pub/susanpcr...

China keeps surging ahead in the global clean energy race. Without a rapid change in US policy, it will leave American firms in the dust. Proposals from our team on how Washington can turn this around are coming soon.

An exciting development: ARPA-E's first funding for supercritical geothermal resources.

$30 million is small, but it's an important first step to unlocking this untapped, high-reward resource. Hope to see more this.

Press Release | U.S. Department of Energy Announces $30 Million to Increase Baseload Power Resources Through Access to Superhot Geothermal Energy Resources
WASHINGTON, D.C. — Today, the U.S. Department of Energy (DOE) Advanced Research Projects Agency-Energy (ARPA-E) announced $30 million to increase geothermal power production by unlocking superhot reservoirs deep within the Earth. Currently, geothermal baseload production in the U.S. is limited to 4 gigawatts (GW). ARPA-E’s Stimulate Utilization of Plentiful Energy in Rocks through High-temperature Original Technologies (SUPERHOT) program aims to provide access to superhot reservoirs capable of producing 10-20 GW of reliable baseload power at a competitive cost.“Geothermal is a reliable and secure baseload power source, but today we are only able to access a fraction of the energy it can provide,” said ARPA-E Director Evelyn N. Wang. “SUPERHOT projects can change that and allow access to hotter reservoirs to create more domestic flow of energy onto America’s grid.”The SUPERHOT program will explore modification of conventional well designs or completely novel designs, materials, and materials systems that satisfy requirements to survive superhot conditions. SUPERHOT’s goals are to develop robust geothermal well construction capable of a 15-year operational life and enable transfer of heat from the surrounding geologic formation to the well. Projects will seek to enable access to resources with temperatures greater than 375 °C and pressures greater than 22 megapascals.SUPERHOT builds on ARPA-E’s history of support for enhanced geothermal projects. ARPA-E’s work in this area includes supporting industry leaders Fervo Energy, AltaRock Energy, and Eden Geopower.Visit the ARPA-E eXCHANGE website for more information about SUPERHOT, including key guidelines.ARPA-E is the disruption wing of the DOE that funds and directs the discovery of outlier energy technologies that are strategic to America's energy security. Learn more about these efforts and ARPA-E's commitment to ensuring American-made energy for all through U.S. leadership in developing and deploying advanced energy technologies. Press and General Inquiries:202-287-5440ARPA-E-Comms@hq.doe.gov

All eyes are on the crisis in the fire insurance market, but we can’t forget the other looming climate-relates crisis: flood insurance markets are not working either. Urgent fixes are needed, argues my team-member @scrawford.bsky.social in her latest piece for @carnegieendowment.org:

Flood risks affect homeowners’ costs and home values, but the housing finance system may not sufficiently account for these risks.

Our system of disaster aid is accustomed to dealing with hurricanes. Wildfires were a sideshow, financially speaking. Now, it will have to cope with a wildfire of hurricane-like dimensions. Here's the details from my team-member @sarahlabo.bsky.social:
