If Condé Nast Can Illegally Fire Me, No Union Worker Is Safe
The Trump administration is making employers think they can ignore their legal obligations and trample on the rights of workers.

Iowa City made buses free in August 2023 with a goal of lowering emissions and encouraging people to take public transit.
Now ridership is up, traffic is down, and the program is extremely popular.
So popular that the City Council has voted to extend it for another year.

A cyclist on a sidewalk is usually a symptom of bad infrastructure.
As I often say, cyclist vs. pedestrian conflicts arise because both are fighting over the scraps of space not occupied by cars. But what if we took that space from cars to make biking, walking, and rolling safer?

my hot take as a full-time pedestrian and transit rider is that i want cities to do the absolute maximum amount to provide cyclists with safe and protected bike lanes everywhere so that i don't have to feel the least bit bad for kicking one off the sidewalk into the street
And before you say anything about Just Do More Public Transit, make your neighbors less fucking neurotic about funding and designing roads for public transit

We often discuss the threat of ocean acidification (and climate change) on shallow #reefs, but it does not spare deep reefs. As the ocean acidifies, the aragonite saturation horizon shallows, and with it the zone many reefs can inhabit. 🧪🌊

Kinda interesting to compare water year precipitation with snowpack at a continental scale. Most of the western US has been very wet since October 1, but there is almost no snowpack anywhere except at the very highest elevations because it has been so ridiculously warm. #hydrology #wx
