Yesssss. There’s a real scientist/bike advocacy crossover happening on my timeline and I am HERE for it @astrokatie.com! We need to start designing roads (and cities!) to prioritize people, not cars.

Katie Mack@astrokatie.com · 24h ago

[redacted person who does not know whose mentions they wandered into]: In my city, the cyclists are so entitled, they act like they own the roads. Me: LET THE BIKES OWN THE ROADS. THE BIKES ARE FAR LESS DANGEROUS AND POLLUTING BY ABSOLUTELY EVERY MEASURE. MAKE THE CARS PAY TOLLS TO THE CYCLISTS.

Michael Longfield, executive director of Cycle Toronto, said the decision is a step back for evidence-based decision making. 'I want to be clear that bike lanes do not cause traffic congestion. Removing them will put people's lives at risk,' he said." www.cbc.ca/news/canada/...

Ontario appeal court says Ford can rip out Toronto bike lanes | CBC News

Big day and not the news we were hoping for. I'm not shocked. I'm disappointed. But this fight isn't over. The facts are clear: bike lanes do not cause traffic congestion; ripping them out will put people's lives at risk. Add your name and stay tuned for next steps: www.cycleto.ca/defendbloor

New data analysis “has provided fresh evidence that cycling is the fastest inner city rush hour transport, with new findings from London showing that 2 wheels beats the tube & cars for most trips…the bike beat 92% of matched trips aligned to TfL services, as well as 75% of rush hour driving trips.”

When you’re well into your public transit commute and realize your pants are still tucked into your socks 😂. #UrbanEcology problems

Beautiful day exploring the Toronto Meadoway, learning about the amazing research community built up around this space!

Look how much space cars take up" is a tired advocacy frame. A more aspirational and community-centred approach is: What does pedestrianization make space for? Statements often polarize, but good questions begin conversations.

If you are an expert on air quality and have 10-15 minutes to talk to me today or tomorrow about important things journalists should know while reporting on wildfires and smoke, my DMs are open, or you can email me at karen at OpenNews dot org.

Almost every city in the world needs to urgently understand the need to get really good at planning and designing for shade. #UrbanHeat

It’s bad enough that it tries to flatter you by telling you you’re asking such good and insightful questions. But desperately egging you on to try to make you spend more tokens is just gross. Like if every time you ran a mass spectrometer it tried to upsell you on some more advanced analysis.

I’ve seen a lot of my colleagues’ interactions with Claude working on research problems & it would be easier for me to accept it as a serious scientific tool if it didn’t end every single response with the LLM equivalent of “you want fries with that?” — constantly trying to goad you into asking more

Bordeaux, France, has now recorded more days above 40°C in 2026 alone than during the entire 105-year period from 1920 (when observations began) to 2025. This is deeply shocking.

Flowers and salamanders and bats, oh my! Second annual lab ‘blitz the gap’ camping trip (in the rain, again 🤷🏻‍♀️). Lots of fun critters despite the weather! Thanks @qcbs.ca 💰

A lot of the press and certainly all of the politicians are very far removed from the reality of being only just able (or able to afford) a bicycle for transportation and it really warps the debate framing

If the wildfire smoke bothers you, commit to one serious climate action. Whether that's joining a local climate group, or making a plan to decarbonize your home, or switching to a more sustainable transportation system. And encourage others to do the same! We're not alone in our fear and anger 🧵

David Roberts@volts.wtf · 4w ago

We didn't previously integrate wildfire-smoke costs into the supposed cost of climate change for the US, and it turns out to be bigger than all those other costs combined. Oops! Gosh I wonder if we're underestimating anything else. Probably shoulda done something about this. Ah well.

Nice reminder of the importance of radiation shields for urban heat studies. Reminds me of this old favourite of mine that I’m constantly sending colleagues in ecology: onlinelibrary.wiley.com/doi/10.1002/...

Ad hoc instrumentation methods in ecological studies produce highly biased temperature measurements

We performed two field experiments to examine the accuracy of three common portable temperature sensors (HOBO Pro, HOBO Pendant, and iButton hygrochron) housed in manufactured Gill shields or ad-hoc,...

There has been an explosion in #urbanheat monitoring using low-cost meteorological sensors. In our paper (doi.org/10.1175/BAMS...) in Bulletin of @ametsoc.org, we empirically show why we need to be careful about large biases in such sensors; & provide guidelines for their effective deployment.

Let's do some Canadian pipeline-wildfire math. The Canadian Energy Center says growing oil exports by 1.5M barrels/day **could** boost GDP by ~31B annually. Meanwhile, wildfire smoke health costs alone - just the health costs, nothing else - averaged 23B/year, past tense. And they're growing fast.

Référendums : les Premières Nations opposées à la séparation

I want people to understand the full impact of the devastation that First Nations in Canada are facing. It's NOT just that people and wildlife are losing their homes...it's the history that is being lost for generations to come.

Just spitballing here, but maybe Canada 🇨🇦 doesn’t need a bunch of new oil and gas pipelines. 🌎

If I were to title this photo, I would call it "Leaving Home." As climate breakdown unfolds, few of us will be spared such an experience. We are all leaving the home that was Earth in the Holocene. 1/

I often give similar advice to my former postdocs / students as they begin faculty jobs: the first year or two are really really hard. It gets much better and is worth it. The successful senior faculty had shitty first years too.

"You feel stretched to the point of breaking. The waves of emotions are rolling over you. I am here, your future self, to tell you that you are enough. You don’t break. You put one foot in front of the other, and you not only make it through, but you have fun." https://scim.ag/3SWodeP

This is one of those videos that reminds me of that tweet: “Climate change will manifest as a series of disasters viewed through phones with footage that gets closer and closer to where you live until you're the one filming it.”

Carbon capture is expensive and largely ineffective at making a real difference on emissions. Especially when the captured carbon can be used for enhanced oil recovery, which lets companies access oil that would have otherwise stayed in the ground!!!

Mark Carney@mark-carney.bsky.social · last mo.

Cutting emissions. Catalysing massive private investments in clean tech. Creating thousands of good jobs.   The Pathways Project will be the world’s largest carbon capture, utilisation, and storage project — built right here in Alberta.

Holy COW. Text analysis of comments on the OMB rule: overwhelming opposition, overwhelmingly not form letters. (But 9 in 10 comments supporting the rule ARE form responses, LOL) Whatever happens next, folks have stepped up.

For example, in the US about 2/3 of people are worried about climate change. But do you know how many are activated? 8%. That’s a gap of nearly 60% who are worried but don’t know what to do. Science causes this “lack of efficacy”. And efficacy is *directly correlated* with willingness to act.
