A real book.

I pray: watch where you step.

For a mere $1000, I'll name a character in my next History book after you.

I'm 30% off! www.mqup.ca/content/sear... And so are a lot of other people!

I get 2-3 AI book promo scams a day. But a self-identifying AI agent reading my obscure blog feels like a Freudian slip from a creepy future.

Saw "Digger." Would recommend! "Station Eleven" meets "Don't Look Up" (meets, uh, "Tropic Thunder").

It’s been so very, very weird to see this little article of mine circle the planet. Here’s the original: theconversation.com/scientists-p... #doomsday

Plus ca change, etc. Ottawa Citizen, 20 Oct 1938

Toronto Star, 9 Nov 1960. Whew, that's a relief. For more, theconversation.com/scientists-p... #doomsday

Sometimes you fall down a rabbit hole, sometimes you jump. Here's a just-published piece of mine on Malthus, math, & magic, in @ca.theconversation.com. 43 days till Doomsday. Should you be worried? theconversation.com/scientists-p...

For the anniversary of Silent Spring, published on this day in 1962. This Peanuts cartoon is from February 1963. #envhist @carsoncenter.bsky.social

To mark the start of Truth and Reconciliation Week, @niigaanwewidam.bsky.social, Gord Hill, and I are excited to share some big news: In January 2027, we will be releasing "A Knock On the Door: A Comic Book History of Residential Schools": uofmpress.ca/books/a-knoc...

According to this moment's version of me. A few perfect. A few imperfect but somehow more perfect for it. Breaking Bad, oddly grudgingly. And had to give a kdrama & an offbeat Aussie comedy some love.

So many moving parts & last-minute scrambling to get this post up in time for Sunday's 50th anniversary of the Ark's opening. Just like the Ark's opening itself! #princeedwardisland #pei #envhist #cdnhist

One of the things we do in this post is annotate & embed the transcript of a 1976 talk by Amory Lovins. Super simple to do - & pretty useful, I think. Lots of potential applications.

This is so sad. My heart goes out to Susan, Jordi, & everyone who loved Karen. She was such a warm & wise mentor to so many, including me. www.queensu.ca/devs/news/re...

Hey! Congratulations to @adeleperry.bsky.social on receiving the JB Tyrrell Historical Medal for outstanding work in the history of Canada.🍁 rsc-src.ca/en/about/pub... #cdnhist

Last day to get your nominations in to @alanmaceachern.bsky.social for a series on Commemorating Canadian Environmental History Describe your topic and discuss its impacts, environmental and otherwise, and how it meets the HSMBC criteria niche-canada.org/2026/08/18/a... #envhist #cdnhist

This is fun: @joshmacfadyen.bsky.social & I have assembled a 3-parter for @nichecanada.bsky.social about the environmental turn on #PEI in 1976. Today, pt. 1 launched: niche-canada.org/2026/09/14/p... Wed, pt.2 on Energy Days. Fri, pt.3 on the opening of the Ark, 50 yrs ago this weekend.

As beautiful a first teaching day as my very first teaching day at Western U, 25 years ago.

Realizing that I'm working simultaneously on 4 small, completely distinct writing projects at the moment. Is that efficient? No. Will any of them lead to a book? No. But are they fun? Yes. Weird? A couple.

In this post, I put out a call for #envhist people, places, or events that Canada should be commemorating. Submit yours: there's a $200 prize at stake. Deadline 14 Sept. Details in post.

Yesterday, I had a 10-minute touch-up laser surgery 5 years after cataract surgery & I wish I could show you just how amazingly good my vision is. I’m going to spend all day today just looking at things.

#PEI has been there. Or rather, not been there.

Trapped in bed this morning. Oh well.

In Thunder Bay today & revisited my home for 2 PhD years: the CCGS Alexander Henry icebreaker.

2035-36: the first year Canadian universities employ more tenured/TT professors over the age of 80 than under the age of 35.

In 2019, the Historic Sites & Monuments Bd of Canada identified 4 strategic priorities for designation. How many of each have been designated since then? 🔵diversity: 33 🔵Indigenous peoples: 14 🔵Can & the world: 9 🔵environmental history: 1 Ouch. niche-canada.org/2026/08/18/a... #envhist #cdnhist

Just an American chemical rep, in the wake of Silent Spring, explaining to a Canadian Parliamentary cttee in 1963 why we couldn't give up on pesticides like DDT: we needed to feed the impending population explosion ...that would, uh, result in Doomsday on 13 Nov 2026. Good times. #cdnhist #envhist

Help settle an argument: Bad Grandpa or Bad Grade Point Average?

Just realized that Doomsday is 100 days away! If the prediction turns out not to be accurate, I'll write about it after. (Because if I publish something in advance & it's accurate, what's the point?) #envhist #envhum

Roadside raspberries, brought to you by #PEI & summer.

The UN recognized 2026 as the Year of the Woman Farmer and I'm so proud to announce the installation of a new exhibition at McLaughlin Library @uofguelph.bsky.social that honours women's contributions to Canadian agriculture. Will be on display until Spring 2027. #womeninag #cdnag #ruralhist

Another round of: “Spot the Cruise Ship”

PEI Tourism may start re-promoting its “cool, health-giving air” of a century ago. “Salubrious” will make a comeback.

Back on PEI. Some research, some meetings, 2 talks - but also this.

Good, long photo-essay about the Statue of Liberty — with some unfortunate ad placement. www.nytimes.com/interactive/...

References in a podcast to “of Island” constantly transcribes to “of Violent.” That’s going to help give me a 2nd title in my #PEI noir series, after “Harlot Town.”
