Did you know air pollution is the top preventable cause of premature death + ill-health in the world today: killing nearly 10 million people per year? And 2/3 of air pollution comes from burning fossil fuels?

Iowa was the first state in the nation to adopt a renewable portfolio standard, in 1983. Since then, more than 30 states have followed suit, "red" and "blue" states alike. This is all about what makes economic sense in a place like Iowa. Not ideological.

Trump opposes wind energy. That could be a tough sell in Iowa.

The president takes his affordability message Tuesday to the state where turbine farms have helped keep electricity prices low.

ICYMI: New online! Environmental data justice is key for developing more effective area-based conservation approaches

Environmental data justice is key for developing more effective area-based conservation approaches

Nature Reviews Biodiversity, Published online: 27 January 2026; doi:10.1038/s44358-025-00126-wScientists disagree about area-based conservation’s role in addressing biodiversity loss. This Perspective examines how conservation scientists, land systems scientists and political ecologists approach these debates differently and argues that environmental data justice frameworks can bridge epistemic divides, helping researchers to develop more effective and equitable conservation interventions.

Best showing in a bit. Maybe the canary in the coal mine (pun intended). Whether they win or not it's an indicator of larger shifts. Good coverage from @westvirginiawatch.com and @lorikerseywv.bsky.social.

First, communities are rightfully worried that big tech will simple abandon the facility when AI bubble bursts.

Second, data centers are terrible neighbors. Increasing electricity prices, limited job prospects after construction, noise, high water stress, air pollution.

Whenever it floods, the UK media uses images of York. It is meant to look terrible, shocking, scary.

But this is an image of resilience. You can see this scene every few weeks in winter! This is York being flexible, a flood being inconvenient but not damaging. York gets on with it.

I‘m baffled by this piece whether the assault on US 🇺🇸 climate policy will have long-lasting effects.

Sure, executive orders might be reversed by the next administration, but the destruction of social infrastructure and technical capacity for science & governance will last for decades…
