America Needs Wildland Firefighters More than Ever, but Attrition Is at Record Levels
Highly skilled firefighters are the last line of defense against wildfires, but that line is fraying because the government decided long ago that they’re not worth very much

Good article, but wildfire is never “preventable”; all of the management strategies outlined will never stop wildfire from burning at some point, but will “mitigate” severe effects and damage to human infrastructure. But fire itself is inevitable in these ecosystems; best accept that fact.

The Turkeyfeather Fire in the Gila Wilderness, NM has burned as a low-severity fire over about 24,000 acres (so far). This is a continuation of a fire regime that existed for millennia before the 20th century. This 🧵reviews the fire history of the Gila, as my colleagues and I have studied it. 1/18

Looks like another record low water year for Lake Powell, on par with 2022 when the lowest water level since filling in 1964 was reached. The "emerging splendor" (Schmidt et al. 2020) of Glen Canyon will continue; time to get out this summer to see Cathedral in the Desert again!

The sparse news coverage that exists of the Billionaire's Coup is, frankly, incomprehensible to a lay audience. "Treasury payment system" is meaningless jargon to most people. Tell people in plain language "Here is what Trump and Musk are doing, and here is how it affects Americans."
