Associate Professor, Earth and Atmospheric Sciences at the University of Alberta. I like things that fly through the air (not shit hitting fan though), science, nature, pottery, and well, many things actually. Opinions are my own and probably questionable.

I found this a powerful article. The entire toxic empathy part is mind-boggling. It is easy to be hateful, self-interested, and only take care of yourself. It is hard to be caring, empathetic and vulnerable. To give a shit. These ass-hats take the easy way out. www.theatlantic.com/ideas/2026/0...

Quote from end of article that reads:

When I see brutality like we’ve all witnessed in Minnesota, I ask myself: Can I really find empathy for people who insist on dehumanizing others? I’m not sure, to be honest. I’m still working on it. I believe our hearts are big enough to hold two truths at once. We can see the humanity in even the worst of our fellow human beings and still fiercely resist tyranny and repression. We can stand firm without mirroring the cruelty of our opponents. These are dark days in America. To rekindle our light, we must reject cruelty and corruption. To be strong, we need more empathy, not less.

The Trump administration's “war on empathy,” Hillary Rodham Clinton writes, “threatens to pave the way for an extreme vision of Christian nationalism that seeks to replace democracy with theocracy in America”: theatln.tc/dcVIzlMi

Very exciting to share that @climatecentral.org is hiring a Climate Data Scientist to join a new climate services effort focused on advancing predictions of risks and hazards on seasonal-to-decadal timescales. The application closes on February 9, 2026 at 5pm ET, & the description can be found here:

Climate Data Scientist | Climate Central

Climate Central is seeking a highly-skilled Climate Data Scientist to join our team. Reporting to the Vice President for Science, the scientist will be part of a new initiative in climate services to ...

This is an wonderful documentary. It shows how important international science ventures are, and highlights the Earth Sciences. One of the most important subjects that isn’t taught in most K-12 schools, creating a crisis in illiteracy about our planet with major consequences. Watch it 🧪⚒️

New video about the JTRACK expedition's work on better understanding stress, earthquakes, and tsunami at the Japan Trench subduction zone: www.youtube.com/watch?v=qoBN... ⚒️🌊

If you are interested in studying participatory cryosphere science or permafrost science feel free to reach out about these opportunities. Will be recirculating in early January. Also for international scholars there's a new funding opportunity for postdocs where these projects could apply as well!

I don't usually do this but if you love nature & quality journalism please donate to The Narwhal. Their work is more important than ever, and are currently trying to raise $200,000 to keep the lights on. You get a charitable receipt, and a donor is matching funds. Please share 🧪⚒️ @thenarwhal.ca

I think you could lessen the firestorm this has started (pun, intended) by making this opt-in. Firefox has been my go to browser since you started. Please, don’t start acting like the others now. Give us the choice please. I don’t want to start over with a new browser, but will. @firefox.com

Firefox@firefox.com · 8mo ago

Exactly. We know not everyone wants AI, which is why our approach is different. Firefox is not becoming an AI browser. Features are optional, clearly labeled, and fully under your control with a total opt-out coming early next year. It won't please everyone but we believe you deserve choice.

#AGU Long time member & attendee. For several years it feels like they lost the plot, extortionate, and the meetings seem more about cramming more in than quality exchange. I was unable to attend for personal reasons, but there are others who couldn’t attend because they didn’t know if it was SAFE 🧵

Rebecca Williams@volcanologist.bsky.social · 8mo ago

I don't even consider AGU anymore. 1) Hostile immigration processes 2) Extortionate cost 3) Size is overwhelming I only get 1 international conference every couple of years, so I need to choose wisely. I get more out of specialist events. And where I feel safer travelling to.

Just happened across this, as well as being great for new Quaternary scientists looking for the good stuff, it's also great for heyday twitter alumni to reunite! Rebuilding that network slowly... Thanks Christine!

My turn for a starter pack! Here is a collection of Quaternary Scientists (broadly defined) that you might find interesting to follow. Enjoy. And let me know your suggestions please! go.bsky.app/71XJ4jH

Very cool work by Bryan Black here at the Laboratory of Tree-Ring Research establishing the exact date of the Electron Mudflow in the Puget Sound metropolitan area: 'Forest-floor burial in 1507 by the largest Mount Rainier lahar of the past millennium' doi.org/10.1130/G537...

This is so cool! I had an amazing undergraduate student right after I started my job, and his research project included looking at the 1842 eruption. We concluded it was not just a phreatic event, but a bit more exciting. I wish this letter had been available then. 🌋⚒️🧪

November 22, 1842, contemporary sources describe clouds of ash "rolling up in great masses, wreathing as smoke from a pipe does, but on an enormous scale" over Washington and Oregon - one of the early documented eruptive episodes of St. Helens (who repeated this spectacle 138 years later)🌋
