@robinsonmeyer.bsky.social makes the point that humans have always reshaped their environment, but the takeaway isn’t license to modify, it’s that communities have figured out ways to govern commons together (Ostrom, not Prometheus) (2/2)

To dig into these changes, Lily did a tour-de-force analysis, including:
-Cloud Controlling Factors
-Mixed-layer energy budgets
-Green's Function analysis

Together, these revealed how climate feedbacks respond to AMOC decline, with extratropical NA warming playing a key role

... and suppresses ordinary convection, but when storms do break, they’re stronger. This is similar to a dynamic we expect to see in a lot of places in a warmer world: fewer moderate rains, more violent extremes.

Each approach comes with uncertainties about whether it will succeed, and interesting questions about equity and reproducibility. And this debate is happening just as we're starting to have long enough records to identify robust model-obs discrepancies

This would leave no indirect costs going to the UC general fund (salaries, tuition support, equipment) or to the Opportunity Fund (faculty recruitment, GSR support, equipment)

Numbers from the 23/24 UC budget request

~2/3 of federal research awards come from the NIH. If the mean OH rate is 50-60%,then capping at 15% would cut total UC overhead cost recovery by about 50%, to ~$500 mill

If other agencies implemented the same OH cap, indirect costs would more or less cover grant administration

True “efficiency” would come from maximizing what we get out of these obs and developing (and executing) a plan for integrating ML into everything NOAA/NWS does
