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!

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

Great work led by @knowlton.bsky.social & 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.

Taylor’s law predicts unprecedented pulses of forest disturbance under global change - Nature Communications Large pulses of disturbance have been observed globally in response to climate change. Using Taylor’s Law, the authors show that those pulses were not unpredictable but expected given a strong scaling...

As the mean rate of forest disturbance is increasing, so does its temporal variance. Proof that Taylor's law also applies to disturbance ecology, and a warning of more severe future extremes. Paper led by @corneliussenf.bsky.social w/ @tommaso-jucker.bsky.social www.nature.com/articles/s41...

Hi! #journorequest here: For HCN, I'm looking to speak with #federal scientists from the West who are preparing for #fieldwork this upcoming season. How has the federal chaos affect your planning?

I'd be happy to offer anonymity. You can reach me at shien.kim@hcn.org or via Signal @shienkim.1721.

Conserving landscape dynamics, not just landscapes Abstract. Protected areas form the backbone of modern conservation. However, the current policies and practices in protected areas reinforce a static view

β€œWithin protected areas, there is an urgent need to rethink what we are protecting: the current landscape conditions or the landscape dynamics that generate those conditions.”

Electric utilities falling behind on emission reduction targets Many of the nation’s largest electric utilities are not on track to achieve their interim emission reduction goals or the β€œnet-zero” targets

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!
