Key developments
Wildfire nights lose their cooling edge
A Science Advances study led by Kaiwei Luo and reported by UPR Utah Public Radio finds potential burning hours rose 36% across much of North America over the last five decades. The biggest increases were in the American West, where parts of New Mexico, Arizona, Colorado, Wyoming and Idaho now see more than two additional burning hours per day. Luo said fire managers should have less confidence that nighttime will reliably slow fires.
Why it matters
Fire crews may be losing a long-standing nighttime suppression window as climate change intensifies fire behavior.

UPR Utah Public Radio coverageUSDA extends digester loan pause through year-end
The USDA extended its pause on new federal loans for anaerobic digesters through the end of 2026, citing significant delinquency rates and realized losses in the portfolio. Inside Climate News reported that 11% of the 746 project lenders nationwide were more than 90 days delinquent, with many digesters operating on large livestock farms in states such as California, North Carolina, Idaho and Iowa. Critics say the technology can entrench concentrated animal feeding operations and add ammonia and water pollution, even as supporters frame it as a methane-cutting tool.
Why it matters
Federal financing is a key lever for whether manure-biogas projects keep expanding or slow down.

Inside Climate News coverageLeaked BHP files show climate backtracking
The Guardian reported leaked internal documents showing BHP halted or delayed emissions-cutting projects in Western Australia's Pilbara, including a proposed iron ore processing plant that internal assessments said aligned with shareholder-endorsed climate plans. Separate Guardian reporting says BHP kept buying diesel trucks for Pilbara operations even though internal materials described the move as misaligned with decarbonisation goals. The leaked material suggests some climate investments could be pushed back by as much as two decades.
Why it matters
It raises questions about whether a major miner's public climate strategy is translating into capital spending decisions.

OPEN QUESTION
How quickly will fire agencies adapt to shorter night suppression windows?
The new study suggests nighttime relief for firefighters is becoming less reliable across much of the West.
OPEN QUESTION
Will USDA tighten digester lending standards after year-end?
The pause was justified by delinquency and losses, so the next policy step will shape future methane-project financing.
