Toronto is at the special triple point, aka that rare "wintry mix" trifecta where the three phases of H2O are rain, ice, and snow. (My skin agrees there is no water vapour present in the air)

Everyone at #AGU25, make your fonts bigger.

Time to see if 2025 'Ove' Glove measures up to the ~2010 model

If you work on sources and impacts of VOCs (biogenic or anthropogenic) from measurement to modeling perspectives please submit an abstract to our atmospheric organics session at #EGU26! Our invited speakers are @dbm.bsky.social and @jacquirickard.bsky.social See you in Vienna! tinyurl.com/55vda8u7

The Canadian government is ignoring research and the voices of green business and is cutting our brand new greenwashing law. Read more in our Globe and Mail op ed today.

Sad the #bluejays lost but honestly could not have handled another extra inning game, especially after the clocks changed

Happy Thanksgiving!

Farewell to my trusty steed (who was apparently liberated by a stranger on Front Street last night)! I bought her at a Halfords during my postdoc in the UK 20 years ago and we spent so much time together (especially during the pandemic) in and around Toronto #biketo

A beautiful day for the last paddle of the summer

Atmospheric Physics faculty position at Univ of Toronto - help us make use of satellite and aircraft capabilities that are on their way in Canada! jobs.utoronto.ca/job/Toronto-...

I'm really noticing how it's getting harder to be relatable to undergrads. My first year teaching I remember saying "10 years ago, I was sitting where you are now" and this semester I had to go with "I've been a professor as long as you've been alive" (insert out-of-touch Simpsons reference)

Is there anything more Canadian than cutting down a pine tree that your flag got tangled up in?

A tactical blunder putting off my cottage holiday until so late that overnight lows are in the single (°C) digits, but the views are still great and I might work up the courage to swim...

Are you interested in biosphere-atmosphere interactions, global modeling, and living in Zurich? If so, this postdoc position might be for you! Please share with any interested colleagues: jobs.ethz.ch/job/view/JOP...

Mostly disturbing but so OTT it can't help but be comical also: www.nytimes.com/2025/08/08/t...

Thanks for your advocacy!

I suspect that spending a week in hospital this spring after rupturing my appendix made Small Rain by @garthgreenwell.bsky.social especially meaningful to me, but the descriptions of home renovation trauma and joy, the beauty of trees, and the close readings of poetry resonated too - such a pleasure

We are looking for a PhD student for a project on chloronitramide in drinking water. Please spread the word! jobs.ethz.ch/job/view/JOP...

Updating a missing link from previous repost... you should still come to Toronto and be my colleague!

Come to Toronto and be my colleague!

I don't think so honey: reporting sampling efficiencies/recoveries/biases in the methods section but then NOT actually saying if the results have been corrected based on these values. Happens so often and drives me up the wall

We are looking for an Assistant Professor (tenure track) in the area of Soil Chemistry. Please spread the word! Application deadline is September 30. ethz.ch/en/the-eth-z...

In a study of professors, women got 378 new work requests over 4 weeks vs 118 for men. Women spent more time on service, advising & teaching; men on research. Orgs should track who is taking extra duties & ensure they are rewarded and distributed fairly. www.forbes.com/sites/kimels...

My kind of patriotism. Happy Canada Day, snack lovers

Such an interesting and enjoyable listen

There have been arguments to redefine #PFAS that seem to be politically or economically motivated. We (20 scientists with PFAS expertise) argue here that the definition of PFAS should be unambiguous and based on chemical structure. pubs.acs.org/doi/10.1021/...

If you're a Canadian Crave subscriber, I can't recommend Empathie highly enough. Incredible writing, acting, and directing, plus you can witness the rich tapestry of Quebecois cursing vocabulary reduced to a single (f)word

We are looking for a postdoc to join our research group at York University in Toronto, Canada to study the atmospheric chemistry of PFAS #PFAS www.cjygroup.com/opportunities

If you are a bilingual climate/sustainability academic that can spend $500,000 to $1 million per year over 8 years, and are willing to move to Ottawa/Canada, you have until July 7th to apply to the 2026 Canada Excellence Research Chair at the University of Ottawa: www.uottawa.ca/research-inn...

This paper summarizing the highlights of Sarah Simon's PhD work was published last fall, but given that #pollen season 🤧has arrived in the northern hemisphere, it seems like a good time to share it here. Kinetics experiments + surface characterization + box model pubs.acs.org/doi/abs/10.1...

Some good news for a change–Queen's has set aside funds to assist any students who have lost their visa status in the US and are looking to continue their graduate studies. Please share widely. www.queensu.ca/grad-postdoc...

The wholesale dismantling of the scientific research enterprise in the US is an unmitigated tragedy, but is sometimes represented as an opportunity for other countries.

This raccoon is out here asking himself "how does Santa make it look so easy to get snacks from inside someone's house?"

Come be my colleague! @uvic.ca is hiring for an Assistant Professor in physical and/or inorganic chemistry. The department is super collegial, and Victoria is a great place to live. If you/someone you know fits the bill, we’d love to hear from you! #facultychemjobs www.uvic.ca/faculty-staf...

O M G .... no wonder he wants to nullify all the agreements related to the governance of the Great Lakes. Spray, baby, spray!

Back when I was choosing grad programs in 2000, I ruled out a group that had an important instrument that had a computer that could only use 5.25" floppy disks. This week I learned a key instrument in my lab depends on a computer that is still running Windows 7. Physical chemist, heal thyself!

Trump has a degree from UPenn, Vance has one from Yale, five out of the six Justices in the conservative Supreme Court majority graduated from Harvard or Yale, most Republican Senators, Representatives, governors, and major donors have college and often graduate degrees, what is he talking about.

When talking about generational differences, part of the discourse is often about "kids these days" needing a reward for every minor accomplishment, but apparently this is nothing new, based on what im discovering as I sort through boxes from my youth

Xiaoying Yang collected many gas phase and size-resolved particle phase samples across seasons and locations in Toronto, which allowed us to study the pH-dependent partitioning and fate of dimethylamine and diethylamine in the atmosphere. pubs.acs.org/doi/10.1021/...

Just finished the amazing short story collection Show Don't Tell by @csittenfeld.bsky.social that concludes with a story that revisits the protagonist of the iconic novel Prep. Satisfaction guaranteed if you are a late Gen Xer who was once an angsty teen and now treats hot flashes with great fiction
