Uncertainties of enhanced rock weathering for climate-change mitigation - Nature Reviews Earth & Environment Enhanced rock weathering (ERW) is a carbon dioxide removal (CDR) strategy that converts atmospheric CO2 to stable carbonates by applying minerals to agricultural land. This Perspective discusses the p...

Enhanced rock weathering (ERW) on agricultural soils is being considered as a carbon dioxide removal strategy. However, uncertainties remain regarding feedstock availability, plant-soil impacts, CDR efficiency, and socio-economic considerations, limiting large-scale deployment. 🧪

Bacteria Decide the Ocean’s Dissolved Organic Carbon Abundance - Eos Dissolved organic carbon prevalence follows from how many bacteria are around to eat it, modeling suggests.

Owusu et al. say that either top-down control (e.g. grazing) or nutrient limitation (e.g. N) shape bacterial communities which in turn set DOC levels in the oceans. The EOS piece by @saimamay.bsky.social is a good summary.

The Biden Admin directed hundreds of billions to clean energy/manufacturing.

Did these investments shift public opinion?

We find that these projects are visible but not traceable: People notice nearby investments, but connect them to Governors, not Biden.

As someone who was, I think, an effective note-taker in college, this discourse about LLM note-takers is alarming. For me, the act of *taking* notes is the important part. If I had thrown the notes away immediately after a lecture or reading a chapter I'd still have gotten 80% of the value.

For those familiar w/ "ARkStorm/ARk2.0" flood scenarios for California, a comparable event has been unfolding on the Iberian Peninsula. These ridiculous rainfall accumulations, caused by a long series of extremely moist atmospheric rivers, have brought widespread severe flooding to Spain & Portugal.

It turns out we’re wrong about what makes ice slippery for 200 years.

We thought ice was slippery due to pressure or friction. New research reveals the cause is molecular dipole interactions. These electrical forces disrupt ice's crystal structure, creating a liquid layer even at extreme cold.

A digital illustration of Skeletor as depicted in the 80s He-Man cartoon. For those unfamiliar he is a a blue man with a fantasy bodybuilder physique. He wears a cross-body harness with some little bones at the center and a matching purple hood that frames hood face which is somehow just a yellow skull. Here he is seen yelling up to the sky and shaking his little blue fists at the heavens. Cutting him off at mid-abs is some gleaming 3D lettering in the style of the Masters of the Universe logo that reads ‘Maybe it will happen today’.
