1/ The State of Ventilation in the US as illustrated by a trip to the #AAAR2022 conference.
Just boarded @RideRTD bus to @DENAirport. 1/3 full, so far I am the only one with a mask (N95 Aura).
CO2 already quite high 5 min. after boarding even tho NOT full: poor ventilation...

2/ Still on @RideRTD bus to @DENAirport.
CO2 steadily climbing. Now over 2600 ppm, meaning >5% of the air we are breathing is "second hand", it has been in someone else's lungs before.
POOR ventilation. ~10 ppl masked our of 45, mostly KN95, few N95, 1 surgical.

3/ Made it to @DENAirport. Eating something outdoors so that I can remove the mask as little as possible in the terminal and the plane.
The CO2 sensor is measuring typical outdoor levels.
