This is literally the method they used for aerosol droplet sample collection.

Gas stoves emit methane, nitrogen dioxide and fine particulates at levels known to contribute to asthma and cardiovascular disease. 🧪 NEW STUDY: The annual indoor health cost of a single gas stove = $5,258 A big part this is from childhood asthma. www.zmescience.com/medicine/gas...

Five years ago, November 10 2020 #Toronto was a balmy 21.6 C. Today? High of 1 C and snowing all day.

Here is the flight track for the aircraft in question. Note the ~250 knot speed because of its low altitude, about 6075 ft most of the flight, with 20 minutes at 10000 ft.

"Great cycling cities do not use sharrows. The end." “We never suggest using sharrows to create a bikeway,” Snyder concludes. “We’ve learned our lessons. Now that we know better, it’s time to do more.”

We have ****ed the climate. Dressing this up as temporary overshoot is indefensible. But this does not mean we are doomed, & it certainly doesn't mean there is no point in trying to turn off the fossil fuel spigot. It's time to get real with climate risks. www.technosphere.earth/derailment-w...

When I was a child we had to separate LEGO flats from base plates using fingernails, teeth and brute force. Not all pieces survived.

Happy 10th anniversary to the best political tweet, ever.

21 years ago I saw the Canadian indie documentary documentary The End of Suburbia and it had a profound impact on my career. This new article by Richard Heinberg serves an introduction and update to the issue of peak oil and what comes after.

New from Canadian Coalition for Green Health Care: Displacement Ventilation: Rethinking Indoor Air for Health and Climate

The motor vehicle-centric societal thinking observed by @shawnmicallef.bsky.social is demonstrated by @ianwalker.bsky.social et al in "Motonormativity: How social norms hide a major public health hazard" doi.org/10.31234/osf... /1

That's ... not good.

New full-length CBC documentary on the iconic 90's music festival, Lilith Fair, on YouTube. Such great music!

Changing the filters on the open source PC fan-based air cleaner. It was still keeping the particulate mass in the bedroom below measurable (0.1 μg/m3) but it's been running for at least 17,000 hours. /1

It's the last weekend of summer, make it count! #equinox

Wayfinding and footpath for the GO Train platform at Bloor Station and to/from the International Centre at Malton Station is horrible. This is my second trip this year and I still took wrong turns and wrong staircases at both stations.

My daughter and her friends made bracelets and sold them at the street festival yesterday. Apparently two or three people bought a pair each, and paid the higher amount!

!! The OpenCPC is now available (Condensation particle counter) presented by @masknerd.bsky.social of @openaeros.bsky.social $5k USD (compared with "contact us for the quote" = price of a car). Counts ultrafine particles and can be used for testing respirators, measuring air quality & filtration

New road markings have appeared in Toronto using the zig-zag pattern to indicate the passenger loading area in the curb lane adjacent to the streetcar stop. #BikeTO

*Seventeen* speed cameras cut down in Toronto last night!?! www.youtube.com/watch?v=tiz0...

Just want to note that, while this criticism is mostly spot on, NACI releases guidelines, not rules. You're "allowed" to get more than one shot per year. If you're in Ontario, call up a pharmacy and if they have stock they'll give you a shot, even if you had one 6 months ago.

Why is NACI allowing only 1 COVID vaccine per year for most Canadians, making many ineligible for the fall vaccine? Everyone should be eligible: 1. It’s an UPDATED vaccine. 2. COVID vaccines begin to wane at 4 months - it’s NOT a yearly vaccine. #Canada #COVID www.canada.ca/en/public-he...

We all need to be a lot more willing to call a lie a lie.

An incredible way to kick off September - celebrating major steps forward in Toronto's low-carbon future!!! I was thrilled to help open Toronto's newest, state-of-the-art, electric heat pump facility from Enwave Energy, providing low-carbon heating to over 10 million sq. ft. of downtown buildings.

The US elimination of the de minimis rule is affecting Canadians. Example: LEGO Pick-A-Brick are shipped from Denmark to the US before being sent to Canadian purchasers. As one Redditor commented: "Ship them straight to Canada, we even share a land border with Denmark now"

Nothing to see here, just a totally normally shaped electoral district.

Note that while the Wahoo ELEMNT ROAM/ BOLT V1 bike computer GPS issue is fixed, it took my unit over 10 minutes into the first ride to get a lock on GPS. /1

New study calculates US could save $1.1T in public health costs by replacing 33k industrial boilers that burn fossil fuels with heat pumps Would save $1.1T in public health costs Prevent 77k premature deaths and 33M asthma attacks And slash CO2 emissions www.canarymedia.com/articles/cle...

I mentioned to a couple of people that I had a surprise waiting to be shared when Moderna got approval for its updated COVID-19 vaccine. It’s approved, and the big news??? Completely produced domestically!!!!! 🥳🤩 Approved as usual for all aged 6mo+!

Health Canada has authorized the LP.8.1 variant adapted Pfizer COVID-19 vaccine for individuals aged 6 months and older. The updated COMIRNATY® vaccine targets the Omicron LP.8.1 variant, one of the most recently circulating SARS-CoV-2 lineages. It will be made available this Fall across Canada.

Look at this badass heat pump! LOOK AT IT!

Done. Please do likewise.

17% price hike by way of shrinkflation: $10 bag originally had 7 uncooked chicken parmesan, now contains 6. Difference in expiry dates is three months. Manufactured by the sneaky little hobbitses at Grand River Foods, Cambridge, Ontario.

I *thought* I had cancelled my annual 🚴Strava subscription (US based, Intervals.ICU is much better for me anyway) but the payment went through. Turns out you have to go through THREE cancel questions sneakily color coded to trip you up before it's really cancelled. Now August 2026. 😡

For me the test is simple. If a road has a lot of cars, it needs a protected bike lane. The road is evidentially useful i.e. goes somewhere that people want to go and is therefore busy. We shouldn't have to wear an Escalade to use it safely.

Straightforward 🇨🇦 messaging in Chatelaine Magazine: If you need an air conditioner, buy a heat pump.
