Ruth Brooker I've heard from so many people that CO2 they see in UK classrooms is around 3,000ppm. It's one of the reasons we measured the long decay at that level. At that level, in effect, the final 10-20% of the exhaled viral load just kind of stops decaying, and begins to accumulate.

Kimberly Prather, Ph.D. 𝙹𝚘𝚎 𝚅𝚒𝚙𝚘𝚗𝚍 [email protected] Prasad Kasibhatla if there were 5 stages of grief for ones credibility after making a mistake that cost that many lives, i think trying to get everyone to agree on new terminology looks like 'bargaining'
Was truly not expecting such an enormous temperature drop of 10°C down and back up again during the #Eclipse2024 . Emotional suspense caused by a cloud bank in the three minutes before totality, it passed with just seconds before totality began! Thank you Barry Hunt - #DavosSafe
The #Eclipse2024 ended for Ontario at around 4:30 PM EDT. Ontario’s solar generation dropped from about 1,800 MW to about 70 MW as the IESO secured other generation to compensate.
