Fire update: thanks to heroic efforts by contractors & USF CMS ops staff, my group got most of our samples. Yesterday books emerged. Waiting for space allocations for prep labs & offices. Instruments & buildings will take longer; advocating for mobile labs in short to mid term. Funding still needed.

It's not just the sun's rays; the wind is doing some big work, too. 💨Did you know, Texas LED the nation for wind generation in 2025 at 129,458 GWh? ❗That outpaced the #2 producing state, Iowa, by ~86k GWh ☀️Texas was #2 for solar generation at 64,073 GWh 📊

As a fire scientist, I am devastated for my many good friends and colleagues who will be affected by the mass closure of so many research stations and offices. Many will leave the agency. USFS has pioneered so much foundational fire science. The consequences of this will be catastrophic.
