I teach chemistry at The George Washington University and study the electronic structure of transuranic materials, homogenous catalysts, and green chemistry. I do not speak for GW.

Today, the Trump administration repealed the endangerment finding: the ruling that served as the basis for limits on tailpipe emissions and power plant rules. Without it, we’ll be less safe, less healthy and less able to fight climate change—all so the fossil fuel industry can make even more money.

As I say here, there is no scientific justification to revoke the engagement finding. In fact, over the last 15+ yrs, the evidence of how climate change affects our health has only grown. Higher risk of allergies, dementia, fertility, heart disease, and death: that’s what’s on the line. @nature.org
There is No Scientific Justification to Revoke the Endangerment Finding
The U.S. EPA's decision to repeal the Endangerment Finding will limit the government's ability to regulate emissions of carbon dioxide and other greenhouse gases under the Clean Air Act.

Hey inorganic people: Does anybody know what happened to the symmetry site at Jacobs university? I see that Jacobs has become Constructor. I'm wondering if the symmetry site - which was crazy useful - has been redeployed elsewhere.

NSF is about to dismantle NCAR at Russell Vought's direction to protect the fossil fuel industry. It's hard to communicate just how much NCAR does, so let's take a look: I've never worked at NCAR, and I've worked with NCAR researchers once ever. What scientific discoveries has NCAR made possible? 👇

Over the weekend ICE abducted an NIH contractor when he showed up to a courthouse for his green card hearing. He is documented. His wife is a citizen.
He is also member of the skeleton crew of animal care staff that works through a shutdown, to ensure the health and wellbeing of research animals.
