Turned NOAA's HRRR Smoke satellite images of #CampFire into a time-lapse. The giant plume of smoke covering the SF & the bay area doesn't really seem to be dispersing, and is instead occasionally blown back from the ocean.

Right out of the new ⁦Sharper Image⁩ catalog. What bogus! HEPA filters do not leave small particles behind. Total BS. These companies can say anything in their marketing and they do. Plus this probably emits some ozone as it’s an ionizer.

Fascinating that they found so much virus on a MERV 4 filter because its removal efficiency is low. Experienced, careful team. medrxiv.org/content/10.110… Must have been lots of passes through the filter and plenty of virus in larger aerosols. MERV figure from sciencedirect.com/science/articl…

.Amber Briggle (she/they), a TX mom of a transgender child has "no more words" to say to AG Ken Paxton, who’s labelled gender affirming care for kids as child abuse. "He broke bread with my family and now he says that families like mine should not exist."

Last night I just had enough. I’m sick and tired of transgender kids getting bullied. So I went to the Senate floor to call out the adults who relentlessly and shamelessly target these kids. I hope you’ll watch this.
