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.

My first social media account ever (except my lab account @tephrotastic.bsky.social). My science is tephrochronology, volcanoes, stratigraphy & climate. I am an amateur potter, advanced procrastinator, middling, but enthusiastic, birder. Growing a garden for bumblebees, can't wait for my next hike.
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.

This is one of my absolutely favourite movies. It is so absurd and amazing. I have no idea how many times I have watched it. However it probably has been a couple years, so I know what I am watching this weekend!

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 🧪⚒️

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
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.
Look, I get that it's frustrating to see @firefox.com make an announcement this tone-deaf, but let's be clear: the same announcement makes it clear that their AI features will be clearly-labelled and can be turned off, which is more than we'll get from Chrome or any of its offspring (Brave, et. al.)

#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 🧵
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.

Attendance at US-based science conferences is bouncing around this year but generally down. #AGU25 has ~10k fewer this year! I explored these trends for @nature.com — including solutions to keep conferences local & productive:

Le démantèlement annoncé de NCAR est un scandale. On brûle une cathédrale de la science climatique qui sera pratiquement impossible à reconstruire. Un recul de plusieurs décennies. Je suis sans mots
NCAR is quite literally our global mothership.
Everyone who works in climate and weather has passed through its doors and benefited from its incredible resources.
Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet.
Unbelievable.
