I was recently invited to present my thoughts on the role of universities in the #climate crisis
Several audience members asked that I share my slides, so I've decided to post them here too as an open resource
I'd love any feedback, & for you to share examples of projects & best practice.

PAY ATTENTION: ICE is filing fake 911 calls in Chicago, weaponizing emergency services to provoke local police.

The GOP has done nothing on healthcare in the 21st century other than stop Dems from improving it. Literally nothing.
Mike Johnson: "Let me look right into the camera and tell you very clearly: Republicans are the ones concerned about healthcare. Republicans are the party working around the clock everyday to fix healthcare. This is not talking points for us: we've done it."

I like this. Since under RFK Jr, Covid shots are now for people with underlying conditions that put them at risk, Michigan’s chief medical executive Dr. Natasha Bagdasarian states that not having the most recent Covid shot constitutes such an underlying condition.
