About to go on CBC Radio's Just Asking, but first -- a shout out to #publiclibraries and librarians everywhere. When I was asked to do the show this weekend I already had a camping reservation at Porpoise Bay. The Sechelt Public Library has kindly provided me with a quiet space to call in.

tune into CBC's Just Asking this afternoon to hear me and @profkharrison.bsky.social talk about @mark-carney.bsky.social's alarming anti-climate policies.

#Ebikes reduce GHGs and other air pollution, offer health benefits, and save money. But there's still a tendency to think of cyclists as gutsy souls making sacrifices. But here's the thing: cycling to/from work makes this 67 yr old, not-super-fit person happy. I'll share why in this occasional 🧵.

Canada's bitumen is disadvantaged in a carbon-constrained world because it's costly and carbon-intensive to extract. US attacks on Iran render cheaper OPEC crudes less appealing though. But with increasingly low-cost renewables, how high a democracy premium will the world pay - and for how long?

This moment in Canadian climate policy rests on two forms of gaslighting. Neither is new, but both are making a comeback in light of rising economic, affordability, and sovereignty concerns. #cdnpoli

Guilbeault speaking now in House of Commons www.cpac.ca/en

PM Carney and Min Hodgson responded to Guilbeault's resignation and Ksi Lisims' LNG contract saying "the world has changed." Yes Donald Trump has disrupted global markets and threatened Canada's economy. Know what else has changed? The global climate.Temps just hit 46C in India. And it's only May.

Is there a better end of work week activity than cycling through sun-dappled bike routes onto the people’s yacht (aka Seabus) for a meeting to talk climate policy?

Another day, another bad take on oil and gas from the Globe and Mail -- this time from Tony Keller. Let's dig in. 🧵 www.theglobeandmail.com/business/com...

Ultimately this is on the BC govt, which did not follow through on its promis to mandate the Zero Carbon Step Code for new bldgs by 2030. BC's Energy/Climate Minister complained BC was undercut by feds weakening industrial C pricing, but BC did the same to city leaders. www.cbc.ca/news/canada/...

"the MOU slightly improves industrial carbon pricing relative to its current status in Alberta – but goodness, that’s a low bar. The losses offset the gains, because the MOU cements a low level of stringency around industrial carbon pricing across Canada for the foreseeable future.

I spoke today about the fed-AB agreement with several CBC stations, including Vancouver's Early Edition. Tldr - federal backtracking on requiring a private proponent? - huge concessions on industrial carbon pricing - BC's reaction curiously silent wrt southern route. www.cbc.ca/listen/live-...

Canada’s MOU agreement with Alberta puts the country’s commitment to net zero emissions by 2050 firmly out of reach. Read our full statement from @rjcsmith.bsky.social ⬇️ climateinstitute.ca/news/mou-wit...

Mayor Ken Sim tries to kill Vancouver's popular gas ban. Again! Vancouver friends, Mayor Sim has to go. The man simply cannot take 'no' for an answer, and he is bound & determine to do the bidding of FortisBC. 🧵 ... www.nationalobserver.com/2026/05/15/n...

$130/tonne by 2040, presumably to become the Canada-wide benchmark. The rationale for $170/tonne by 2030 was that modelling indicated that was what was needed to meet Canada’s original Paris target of -30% by 2030. Canada has no credible plan to meet its current NDC. www.cbc.ca/news/politic...

No detail on how the Clean Electricity Reg will be revised (even though this is surely part of the fed-AB negotiations), but seems to be asserting that to get to net zero in 2050 we need to burn more gas. No acknowledgement at all of Canada’s 2030, 2035 Paris targets www.cbc.ca/news/politic...

Canada’s new electricity strategy rightfully emphasizes clean electricity and electrification as a backbone for the country’s competitiveness, but sidesteps critical issues. Read our full response from @dalebeugin.bsky.social ⬇️ climateinstitute.ca/news/canadas...

Didn't have Jesus supports a pipeline on my bingo card! Plus when asked when her government would reject the "notion of climate change" Smith said "I’m trying not to be too hardline one way or the other.” A biblical claim of "stewardship" demands ignoring climate change. thetyee.ca/News/2026/05...

Curious. LNG Canada is committing to $100Ms toward a final investment decision, but what are federal and provincial govts committing other than agreeing to pretty obvious shared goals: create jobs, diversify exports, collaborate with FNs, competitiveness? 1/2 archive.news.gov.bc.ca/releases/new...

Sickening, but an important read. “The blunt reality is that when there are no consequences, we humans are capable of immense depravity toward those we are taught to scorn as subhuman.” www.nytimes.com/2026/05/11/o...

Our latest analysis shows that the emissions implications of the Canada–Alberta MOU will depend primarily on one key factor: how the industrial carbon market is updated. https://440megatonnes.ca/insight/canada-alberta-mou-treatment-industrial-carbon-pricing-emissions-outcome/

Some of Canada’s top trading partners already have industrial carbon prices in line with the Canada-Alberta MOU ($130/tonne): EU: C$120 Norway: C$120 Switzerland: C$119 UK: C$85 Our new analysis of the MOU shows strong carbon markets can drive big emissions cuts⬇️ 440megatonnes.ca/insight/cana...

Good morning with good news: Solar globally grew by 600 TWh in 2025, largest ever rise from any source, excl rebound yrs. RE & nuclear growth was more than total electricity demand growth. Fossil fuel generation DECLINED! RE = coal generation! iea.blob.core.windows.net/assets/ade8f... #energysky

VERY BIG NEWS out of France a week ago: "French Prime Minister Sébastien Lecornu announced on Friday, April 10, a ban on installing gas heating systems "by year's end" in new buildings, including multi-unit housing, to curb France's dependence on fossil fuels." www.lemonde.fr/en/environme...

Canadian oil producers hope to capitalize on instability in the gulf - plus government subsidies - to expand Cdn exports. But the Iran war's impact on prices is hastening the shift away from oil in importing countries, reinforced by ZEV mandates that spur lower pricing of EVs. Pipeline to nowhere?

It *seems* the Yukon is the first Canadian province to face a conflict between its climate ambitions, which demands expansion of clean electricity, and its electricity capacity. I have thoughts! www.cbc.ca/news/canada/...

I can't stop laughing at this post. It's perfect.

Former NASA climate scientist, now Senior Scientist at Project Drawdown, Dr. Kate Marvel, has a fantastic piece in the New York Times today. This is a must-read if you care about science, the planet, and the future. www.nytimes.com/2026/04/08/o...

It's #givingday at #UBC. Donations to the Political Science Learning Fund support experiential learning. Professors (including me, also an alumna), who know the value of these opportunities for our students, have contributed $2000 to match other donations. Join us! givingday.ubc.ca/32770/gd2026...

“Compared with non-active travelers, the cyclists had a 19% lower risk of all-cause dementia, a 22% lower risk of Alzheimer's, a 40% lower risk of young-onset dementia (before the age of 65), & a 17% lower risk of late-onset dementia.” Connecting bike-riding with reduced dementia risk. #UrbanTruth

This is needed, province-wide, to save lives in the next heat dome (and there will be another.) The building code protects those in new buildings, but the most vulnerable are renters in the older bldgs. New Westminster Requires a Cool Room in Rental Units to Save Lives thetyee.ca/News/2026/04...

Heartbreaking. Btw Dr Marvel is speaking at #UBC April 15. Link next in thread. Prominent Climate Scientist Resigns From NASA, Citing Trump’s Attack on Science www.nytimes.com/2026/03/25/c...

What will industrial carbon pricing cost the oil sands sector if the Canada-Alberta MOU moves forward? Our latest research shows costs would be minimal—just a Timbit per barrel if the price reaches $130/t in 2030. https://ow.ly/QtNF50Yslm5

Good news: Scientists were wrong about how bad sea level rise is. Bad news: It’s even worse than we thought.

I cannot recommend Marvel’s book, Human Nature, strongly enough. I learned things, and I laughed in parts, but most importantly I was moved to tears — in a good way. She’s speaking at UBC April 15!

Canada's definition of inefficient fossil fuel subsidies already had so many exceptions that it could justify almost any subsidy. But seems like we're not even making the rhetorical effort anymore when it comes to subsidizing fossil fuel expansion. www.theglobeandmail.com/canada/artic...

A good thing to remember every time you’re thinking about supporting US businesses or tourism, Canada.

Last week Canada announced it will develop its own tailpipe standards for GHGs. That's about to get way more urgent. When EPA repeals the endangerment finding its GHG tailpipe standards, which are predicated on that finding, will immediately be defunct. Cdn law references US regs that won't exist.

Last 6 mins, from 20:30 on. "William Shakespeare, 400 years ago." 👏

Bets on how soon we get an announcement that BC ZEV Act will be repealed? I'm thinking by noon today.
