Last week, a friend and I planned to visit Sedona but were foiled by the
#PocketFire
. A week later, it grew 100 fold to ~10,000s of acres. Much of the Southwest is burning, and there's an glaring driver: climate change. Until humans get our act together, this still needs to be said.

How climate change is driving Arizona's Pocket Fire and other blazes
Climate change brings warmer temperatures and drier weather — conditions favorable for a rapid spread of wildfires.

Forests are reorganizing in their composition and structure in response to climate change - will they be able to maintain their carbon? Turns out: yes - they even sequestered more carbon than resilient forests! New paper out in Global Biogeochemical Cycles 🔄💎

I’m really concerned about early career scientists using generative AI in writing, because writing is how we think and reflect. There’s almost nothing *more* human than that, and to give that gift away to a machine is almost unconscionable to me

& hopeful takeaways for forests of Greater Yellowstone! Rather than failing to regenerate after fire, forests may shift in composition and structure throughout the 21st century.

Our new report finds utilities are falling behind on interim emission reduction goals promised to investors and customers. This trend is made more concerning given it is playing out against the backdrop of the Trump admin's attacks on climate policy.

Excited to connect with folks here! I work with forests, fire, and people who live with forests that burn. Last year, we partnered with the UW-Madison media team to produce a video on some of the Turner lab’s work in the Greater Yellowstone Ecosystem. Enjoy!
