According to ASHRAE standard 241 on the control of infectious aerosols, supply of clean air to a patient exam room sufficient to mitigate the risk of disease transmission should result in CO2 concentration of around 700 ppm, whereas my sensor was recording more than double that.

Clean indoor air should be a basic right guaranteed by legislation. Poor ventilation is common, invisible, and public awareness of the health impact is low. Here's a CO2 reading from a medical clinic (!) in Halifax yesterday:

There’s lot of Covid going around at the moment, again. I don’t qualify for NHS jabs, which are now very restricted, but I just paid £90 for one at my local pharmacy. As a freelancer, that’s a lot less expensive than having to take a week or two off if I get ill, let alone risking long term issues.

Apropos of nothing, here's my essay for @newrepublic.com from earlier this year about Covid's continued influence on our lives, whether we like it or not: newrepublic.com/article/1927... (Thanks again to @dceiver.bsky.social for letting me write it.)

"À la lumière de ces données, Piétons Québec constate que dans 20 % des 184 collisions mortelles survenues pendant la période étudiée, le conducteur du véhicule avait omis de céder le passage au piéton." Ouaip. Je ne tombe pas pantoute de ma chaise 🙃

to be fair the post office was printing money at that time. mail made so much money it subsidized passenger rail lines until trucks took over

Canadians fought for walkable streets. Côte-des-Neiges, Montreal, June 22, 1955, part 2: After a driver injured a 7-year-old boy, about 40 women blocked the intersection of Clanranald and Van Horne avenues, demanding safer conditions for walking and letting no motorists through.

150 à 180 $, ouch… Au moins le vaccin pour la grippe reste gratuit, mais quel manque de vision. Tout le monde est à risque de la covid, un vaccin gratuit c’est le minimum.

tldr humanity needs to engineer buildings around filtered air replacement rate and it's not even that dramatic but for dramatic results

⬆️ ventilation = ⬇️ Covid HAIs Increasing from 1 to 6 ACH = 50% reduction (~40% to 20% attack rate) Increasing from 6 to 10 ACH = more reduction (~20% to 10% attack rate)

Traveling on N-American railroads is like watching priests performing the rituals of an obscure lost religion: weigh the luggage, leave votive offers, open just some random doors, shout some inaudible psalms in the loudspeaker, close the doors, pull the stool, ring the small bell, ring the big bell.

As soon as Air Canada knew the strike was real, they made a deal. In other words, if the government had told Air Canada that they wouldn't force the striking workers back to work, this whole thing would've been avoided. The government constantly siding with corporations is why this chaos happened.

As our kids go #BackToSchool, never forget that we ARE the traffic that we’re afraid of. If more kids walked, biked or rode transit to school, it would erase a massive number of car trips each day, and our kids would be safer, healthier and better at school. HT Ian Lockwood. Spread the word.

Air Canada’s CEO gave striking flight attendants more reason to defy a government order to go back to work. On BNN Bloomberg, CEO Michael Rousseau says the company didn’t make provisions for passengers with cancelled flights because it assumed government would enforce Section 107 to end the strike.

If you’re in Toronto, get out to Pearson to support the Air Canada wildcat strike. This is the most important labour action in years. The government’s use of Section 107 is an act of war on labour, and CUPE is refusing to lay down their arms. If you want a future for labour in Canada, get out there.

Mind the Gap! Across Montréal, cars get nearly 98 per cent of the roadway, while micromobility gets just 2.32 per cent. Yet micromobility users account for nearly 5 per cent of all trips. That gap matters. momentummag.com/is-there-spa...

Press needs to stop repeating govt euphemism of “clearing homeless camps.” I’ve witnessed it in other cities: massive destruction of personal property. Not just bedrolls & tents; family photos, Bibles, meds. Times I’ve seen it people weren’t even given option to move their things.

The reason Israel has killed journalists with impunity throughout this genocide and continues to do so even as famine sets in and world opinion turns against them because it is in the interests of them, their political allies and their backers in the media to destroy as much evidence as possible.

Eleven more libraries will reopen on Sundays, thanks to the leadership of the City Council. They never should've been closed in the first place. As Mayor, I'll end this absurd budget dance that keeps our beloved libraries in limbo year after year.
