US science agency reclassifies hundreds of workers as probationary, US lawmaker says
National Science Foundation administrators reclassified hundreds of employees from permanent to probationary status in violation of labor contracts, according to a U.S. lawmaker and agency employee.

Climate change has never been clearer, and this is in part due to brilliant work by US climate scientists. Yet the Trump administration is trying to outlaw even the word 'climate'. The "leader of the free-world" is undermining that title in every possible way.

I think it’s not helpful to repeat claims that the administration is working on eliminating “DEIA” as though it’s some kind of corporate strategy; just say explicitly that they’re trying to eliminate diversity, equity, inclusion, and accessibility, and explain how.

Two papers in Nature Climate Change suggest that exceeding 1.5 °C in 2024 may indicate that we have entered a multi-decadal period of 1.5 °C average global warming.

You’ve probably heard that trees share resources through an underground network of fungi—that story is everywhere. But it is not supported by much evidence, & scientists are walking back early claims. Here, I ask why there is so much resistance to changing the story 🧪 #PlantScience #SciComm

A study in Nature Cities on access to running water in large US cities since 1970 finds that the 2008 financial crisis worsened household ‘plumbing poverty’ in many cities. This generally squeezed lower-income households into more precarious living situations. 🧪
Urban inequality, the housing crisis and deteriorating water access in US cities - Nature Cities
Meehan and colleagues study access to running water in large US cities since 1970, finding that the 2008 financial crisis worsened household ‘plumbing poverty’ in many cities. This disproportionately impacted households of color and generally squeezed lower-income households into more precarious living situations.
