"Mosquitoes in Iceland are more than a curiosity or future annoyance. They are a warning …" - Amanda M. Koltz and Lauren E. Culler
Iceland—previously the only Arctic nation without mosquitoes—no longer holds that distinction.
"The detection of mosquitoes just north of Reykjavík in 2025 reflects an ecological shift already underway," write Amanda M. Koltz and Lauren E. Culler in a new #ScienceEditorial. https://scim.ag/4tg86pJ

This figure shows how snowpack (measured as Snow Water Equivalent, SWE) in a region evolves over a typical year, and how the current year (2026) is well out of historical conditions. https://nwcc-apps.sc.egov.usda.gov/awdb/basin-plots/POR/WTEQ/assocHUC2/14_Upper_Colorado_Region.html

The notion of an "alternative" world of fact and law, analogous to and epistemically on a par with the normal one, is – and this is a technical term – complete bullshit: en.wikipedia.org/wiki/On_Bull...

As an atheist I'm agreeing the the @Pontifex! Well done!
"Enough of the idolatry of self and money! Enough of the display of power! Enough of war! True strength is shown in serving life. "
It's so good to hear an American say this!
The magnitude of these forecasts continues to surprise me. Strong El Nino events are quite uncommon, happening only once every 15 years or so, and often on the heels of a moderate event like the 2023-24 El Nino.
"The average size of wild animal populations has collapsed by > 73% in the last 50 years. Vast swathes of rainforests & other ecosystems have been destroyed. The oceans are being emptied of life. Microplastics riddle the environment and our bodies...Warm water coral reefs are being exterminated..."
Absolutely remarkable statement from Pope Leo today.

The University of Michigan has been measuring consumer sentiment since 1952. We just got the first Iran-afflicted measure for April, and it's at the lowest level ever recorded.
Wildfires are becoming more frequent and are ravaging new parts of the world due to global warming.
A new study combining 13 climate models finds that nearly 84% of species already vulnerable to wildfires could face even greater risk by the end of this century.

Uruguay generates nearly 43% of its electricity from wind and solar. In 2010, the share was less than 1%.
Most of the rest if hydro.
Today, Uruguay produces nearly 99% of its electricity from renewable sources.

Exciting news! I’ve been following Mason’s work for years and it seems he will be sitting across the street now!

Two things strike me about this story. 1. Preston seems to have been genuinely unaware that AI might simply lift stuff from another review. I guess I am surprised, but maybe shouldn't be, that folks like this will use AI with so little understanding of it. And...

cover of the book "Bayesian Workflow" by Gelman, Vehtari, et al. Coming out later this year, in the summer probably.
I would have preferred to have the "draw the rest of the owl" meme on the cover, but this will do. Seems like it is on schedule, and we'll leave some typos so you know we didn't write it with AI.

NSF LTER program “archived”.
LTER=“Long Term Ecological Research”.
This program has been incredibly successful, incredibly frugal for what they accomplish, and…of course…targeted by evil know-nothings.
My heart is breaking.
What a tragic and unnecessary loss brought on by cruel policies cruelly enforced.
The broader picture is that while some of the GOP's war on science will be reversible, some won't. Never again in my lifetime will the best and brightest from around the world want to study and work in the US.
