I wanted to share probably the most important sermon I’ve given and it’s while I’m being arrested. It’s torture pure and simple what happens at #Broadview. I’m ok, though I was thrown to the ground and choked with my pectoral cross. A review of the video shows I was peaceful - did I deserve this?

Seems like the #Aurora is already visible over a large chunk of the CONUS tonight thanks to the #CME's over the last few days from a couple of significant X-class solar flares.

Just out: new New Jersey state sea-level rise assessment
Under current global emissions trends, New Jersey is likely to experience 1.5-2.5 ft of sea-level rise between 2005 and 2070, 2.2-3.8 ft by 2100 (or 2.2-4.5 ft, considering potential ice-sheet collapse).

Last year, @michaelfwehner.bsky.social and Jim Kossin made the scientific case for a Cat6 cyclone. This week, Hurricane Melissa became the 6th storm in recorded history to smash through that threshold, with max winds of 216mph. And conditions leading to these storms are on the rise.
