"The realization is yet to set in with the public that 90 per cent of the cost of this multibillion-dollar project — we don’t know how many multiples of billions yet — is going to be paid by Alberta and Canadian taxpayers, just as we were promised would never happen." thetyee.ca/Opinion/2026...

Taxpayers will be on the hook for billions to bring oil through BC’s Lower Mainland.

New from me. Mark Carney’s Oprah giveaway day, and a vexing question: if a new pipeline is a money-printing machine, why does no private company want to build it so that taxpayers have to? #cdnpoli www.theglobeandmail.com/politics/opi...
Opinion: Welcome to the Mark Carney major projects sweepstakes
You get a port! And you get a tunnel! And everybody gets a pipeline, whether or not they want one!

When reality surpasses fiction! Top: fictional forecast for August 2050, broadcast by French TV in 2014 to warn about the consequences of global warming. Bottom: Real French forecast for yesterday, June 22, 2026.
Thick exposures of Quaternary sediments in the Churchill River area record at least three glacial-interglacial cycles and provide valuable insights into past glacial dynamics and interglacial climates. A fun area to work in. doi.org/10.1139/cjes...
Laurentide ice sheet dynamics across multiple glacial–interglacial cycles from Quaternary stratigraphic records in central Canada
Quaternary terrestrial stratigraphic records are key to understanding the long-term behaviour of past ice sheets beyond the most recent glaciation. Glacial sediments provide important information on i...

Did you know? Pixar’s film, Hoppers, worked with real scientists to reflect real-world ecology. 🦫 Dr. Emily Fairfax, one of the experts, also authored GSA Special Paper 562, showing how beavers support biodiversity and help landscapes recover from wildfire. 🔗 Learn more: geosociety.co/beavers

It's important to thank the volunteers around you. We all do it for different reasons, and are there for the ups and downs. Here's to more ups and thanks to all who I have volunteered with over the last 20 years.
Guess what. Glaciers aren't as good at eroding the landscape as we might have thought. New paper with collaborators from Quebec, France, and across the US. Internationalism lives on at least in science! gchron.copernicus.org/articles/8/1... ❄️🧪💙📚 #scicomm #climate #UVMresearch #science 🌎 🔬 ⚒️
In situ cosmogenic 10Be and 26Al reveal the complex exposure and erosion history of the landscape once covered by the Quebec-Labrador Ice Dome
Abstract. The rate at which ice sheets erode rock and produce sediment is poorly known. Here, we use paired cosmogenic nuclides in both deglacial and modern sediment to understand better the efficacy ...

After about 5 years (!) of keeping secrets, I am so excited that Disney Pixar's Hoppers is finally coming out on March 6th! Back in 2021, Pixar emailed me asking if I could give a talk about my research to their employees. Then another talk. And another. 📸 Disney/Jesse Grant/Getty Images
Our new paper is out, in proper format, in CJES today. It's a continuation of our stratigraphic framework development in the southwest HBL, together with Paleo environment data (UofT) and optical dating (UFV).

Absolutely true - I am more and more aware every day of the need to question established 'common knowledge'.
Lily Dove@solilyquy.bsky.social · 9mo ago“I have found that the longer I exist as an expert in my own field of science, the less I like to assert a piece of knowledge with great certainty.” Beautiful writing that is helping me reflect on my assumptions in oceanography (and all the other amazing things I have the honor of learning!). 🌊
I also told students to me more like the cuttlefish - again, don't take the marshmallow because it is quick and easy and right in front of them

Cuttlefish show they can be patient and ignore a snack that’s right in front of them to hold out for a more tantalizing treat.

Stopped the bike ride for a little geology. Fascinating mud cracks that peel off in layers, and sticky clay underneath. Little minds shocked and amazed when they learned that mud cracks are found as 'fossils' too. #geology
Congratulations to Mr. Mesich who successfully defended his MSc today at UWaterloo. It's been a pleasure serving as your co-supervisor with Dr. Ross. *Quaternary stratigraphy of the Gods and Yakaw river areas, northeastern Manitoba*
Fire-induced rock spalling! This area burnt about 1-2 months ago. All of the little rock shards on the ground are spalled pieces of the granite boulder, overlying burnt soil and moss. Before seeing this in person, I didn't really consider the mechanical weathering effects of fire!
Campground foraging near the Manitoba Escarpment. A lot of work for a little bit butter. Makes me grateful for farms and grocery stores.
