In the era of affordability politics, making clean energy cheaper may be a more viable emissions mitigation strategy than making dirty energy more expensive. My latest over at The Climate Brink digs into the debate:

I often get asked about the Miyawaki method of forest restoration, usually by people who have heard extraordinary claims for it. Morales et al. (2025) have reviewed the evidence and found it to be weak or absent. 🌏🧪🌳🌲 besjournals.onlinelibrary.wiley.com/doi/10.1111/...

To scale up restoration effectively, practitioners and policymakers should prioritize methods supported by robust empirical evidence rather than relying on untested claims. Our findings highlight the...

A group of people in a conference room look at a speaker and a screen that reads "Speak out to save NCAR." In the foreground, a sign reading, "We love NCAR" leans against a seat.

UCAR President Antonio Busalacchi stands at a podium in a conference room. Beside him sits AGU President Brandon Jones. There is also a large screen that reads, "Speak out to save NCAR!"

At an @agu.org Town Hall today, @ncar-ucar.bsky.social President Antonio Busalacchi spoke to #AGU25 attendees about what's at stake if NCAR is dismantled.

One attendee asked anyone who uses NCAR research to stand up. Almost everyone in the room stood.

The future of the Amazon may rely on its past. According to study, landscape interventions by the forest’s pre-Columbian Indigenous inhabitants might still affect its ecological functions, including its capacity to store biomass, absorb carbon, and withstand climate change

Portions of the forest managed by pre-Columbian populations hold higher biomass and are more able to withstand climate change.

We offer three considerations on uncertainties and potential misapplications of global datasets, to ensure results appropriate for decision making.”
