Maybe for their next trick, #NYT will account for the human and environmental health externalities of petrol (and even hybrid) powered autos. I drive an #EV for a lot of reasons. Cost of charging isn’t one of them.

The group that authored a controversial report sowing doubt in the severity of #climatechange has been disbanded. I’ve said and written many times before, what to do in response to climate change is very much an open question. But whether climate change is real and consequential is not.

The group’s end can be traced to a lawsuit alleging the group’s formation violated federal law in several ways.

Just learned my home in DTLA is in the curfew zone. At once bummed and proud about this. Bummed for the local shops and businesses whose employees won’t earn a full day’s pay. Proud of my city and neighborhood for standing up to bullies.

My terrific colleague, @alexsegrecohen.bsky.social, led a study where we looked at US counties with worst drinking water violations.

What a privilege it was to discuss the energy transition and a bipartisan strategy for making progress on #climatechange with someone I so admire: Jennifer Granholm. Thank you Secretary and Governor Granholm for spending a few hours with me at USC today.
