Boise ID just unearthed a 1.6k SARS2 sample

[Adam Wong @Engineer_Wong]

People would voluntarily wear masks if bioaerosols were visible to the naked eye, like in this video.
When smog was visible to the naked eye in China, everyone knew how harmful it was—you couldn’t see far into the distance. Where I live now, the air still has 40+ μg/m3 of pollution for most of the year, but it’s no longer visible to the naked eye. So people have stopped talking about smog.

People in DC right now, in full Covid denial, making a post about a “weather headache” while CyFi has the city surging hardest on ED visits since August and hitting 12+ week highs:

“That time of year again! Anyone else’s sinuses and head kinda hurtin’?”

Comments immediately ABC:

“Ragweed pollen is a thing and everyone’s gonna have a reaction to it… you don’t need to have an allergy to ragweed- it will just set your body off cuz it’s not normal for us to be breathing it…”

Someone notes the sources show ragweed is LOW and PEAKED WEEKS AGO.

OP: “Oh wow! Yikes! I’m stumped then. This is something in the air because I’ve been sneezing like a maniac… heh maybe its some new kind of pollen that’s not being measured yet, like that invasive species tree in DC. Tree of heaven? IDK.”

Final comment: “It’s likely barometric pressure triggering the migraine.”

The weather headache, invisible ragweed allergies, tree of heaven and barometric pressure are really putting in work. ABC 🫠

Water temperatures along California coast continue to warm & have now reached genuinely *astonishing* levels. At the Farallon Islands--usually the epicenter of NorCal's infamously frigid upwelling zone--temps now exceed 66F, shattering all records for this late in calendar year.
