Under the UNFCC Canada is not responsible for the downstream combustion emissions of the fossil fuels we export. So we conveniently ignore them (as in Ksi Lisims Assessment and BC and fed announcements today), though those GHGs are more than Canada's territorial emissions to the global atmosphere.

Today marks a major development in U.S. climate policy. Gov. Newsom, the CA Assembly & Senate just released the final cap-and-trade—now called cap-and-invest—reauthorization bill: AB 1207. 1/ #climatesky #energysky

I've been getting requests from reporters about the disbanding of the DOE Climate Working Group. Here are some comments. More to come on my Substack (www.theclimatebrink.com).

Part of me is sad I will never see DOE's attempt to respond to the excellent comments from the scientific and economic community on its awful climate science report A larger part is relieved this document will be expunged from the administrative record A small but real victory for accuracy and fact

DOE's embarrassment of a "climate science" report is 150 pages where as this response from the scientific community is 500. My take: It takes much more effort to refute nonsense than it does to generate it, a tax on the time of all who care about fact and accuracy sites.google.com/tamu.edu/doe...

trains are such a great example of how the future is here, if we want it and are willing to subsidize it

What an impressive shift from FF to renewables and storage for new generation capacity over the last 2 decades in the US (www.eia.gov/todayinenerg...)

Developing a new method to answer whether environmental markets actually improve allocative efficiency. California's RECLAIM program improved allocative efficiency, but the US's NOx Budget Trading Program did not, from Kyle C. Meng and Vincent Thivierge https://www.nber.org/papers/w34111

A point made insufficiently: nations of the world are lining up to poach US scientists and Harvard-bound students. They are not coming together to think about the hole in global science the Trump administration is creating. That's a problem.

Three issues with the term "decarbonized" oil: i) It is silly. Oil contains carbon and emits CO2 when combusted. ii) Doesn't even make sense for production emissions, because carbon capture and storage doesn't capture all emissions (can be <50%) iii) Our trading partners know (i) and (ii)

Excited to open the call for papers for the 40th Canadian Econometric Study Group (CESG) conference. The conference will be in Ottawa from October 17 to October 19, this year's theme is `Credible Econometrics'. For more details, see caneconometrics.ca/annualMeetin... #econtwitter #cdnecon

GiveWell sought an independent check on the evidence supporting >$1 billion it has granted to its top charities. This fall, Alex Cohen asked whether we could obtain the datasets needed to reproduce the underlying RCTs. We said yes; charging only a modest fee to cover our time. 🧵 + 🐀 + blog post!

It's a good sign when Alberta criticizes the pick for Federal minister of the environment! The opposite would be worrisome. www.ctvnews.ca/edmonton/art...

We've got the @katharinehayhoe.com stamp of approval! That's awesome.

If you are a bilingual climate/sustainability academic that can spend $500,000 to $1 million per year over 8 years, and are willing to move to Ottawa/Canada, you have until July 7th to apply to the 2026 Canada Excellence Research Chair at the University of Ottawa: www.uottawa.ca/research-inn...

From me on the urgency of updating industrial carbon pricing systems in Canada: climateinstitute.ca/federal-gove... The 2026 interim review isn’t fast enough to bring much-needed certainty to 🇨🇦 carbon markets.

Canada’s new govt should act swiftly to finalize methane regulations in the oil and gas sector. SK, AB, and BC have already cut oil and gas methane in half in less than a decade. Reducing methane is low-cost action and more progress is possible. 440megatonnes.ca/insight/how-...

Attention climate scholars seeking to leave the US: Next year the University of Ottawa will be seeking int'l candidates for a Canada Excellence Research Chair in "Climate and Societal Solutions" (broadly defined) They'll seek established scholars with global reach in this area (see below)...

After Turkey, Brazil! I had not seen this. EU's climate club is taking shape.

California is planning to extend its cap-and-trade passed 2030 to provide further program certainty in face of the White House threat. Awesome! www.gov.ca.gov/2025/04/15/g...

I had missed this, but it looks like Trump's April 8th executive order may kill California cap-and-trade system (www.whitehouse.gov/presidential...)

My advice to friends in UK and Germany last week, in anticipation of coming Trump tariffs: 1. Stand firm. Preemptive concessions & weakness don’t work with Trump. 2. Don’t take the bait. Calm & steady. 3. Look for off-ramps. Offer to negotiate. 4. Stay united, at home & with partners.

I don't even need to doom scroll, I've got all the daily doom dose I need with the first five posts I read when opening bsky. Sacrament que ça va mal!

If Canada survives another 100 years, Manitoba's moment with Wab Kinew will feature as prominently in the history books as a bunch of other things happening right now.

One less-noticed success in the Canadian counteroffensive: The most famous thinkers at Yale — specifically writers on fascism — are being serially scooped up by the U of T’s Munk School as they express a desire to flee the Trump assaults on universities

It took detaining a white Canadian woman for the public to get a glimpse into ICE detention. The stories she tells—of her dehumanizing experience & that of so many other women—are horrifying. This is America. Not new to this administration, just ramped up. www.theguardian.com/us-news/2025...

🚨 First PhD paper in @pnas.org 🥳 🌊 @edualastrue.bsky.social and I looked at how much less CO2 will be taken up by the ocean if the #AMOC weakens - and how this reduced ocean carbon uptake affects the social cost of CO2 emissions. 📝 Read the paper here: doi.org/10.1073/pnas... 🧵 A thread [1/11]

A close friend lost their dream job as a USGS scientist yesterday. It took years to get, removed in a few months. Devastating is a euphemism!

This is a deeply stupid and offensive article. The @nytimes.com is failing to rise to the moment in spectacular fashion.

Bravo!

Dear @pbsnews.bsky.social when a fascist is threatening an invasion and annexation of a sovereign nation you in fact do not have to respond by explaining how it would work WTF is “Here’s what it would take to transform Canada from a nation to a state”?

Canada & Mexico should put tariffs on US oligarchs If Tesla wants to sell cars in Canada & Mexico then Musk himself, as main shareholder of Tesla, should have to pay tax in Canada & Mexico Put a wealth tax on him, and condition Tesla’s market access to him paying the tax 7/x

The illegal funding freeze still in effect is an incredible waste of taxpayer dollars. Across the country, projects are pausing construction and laying off staff. This will slow work to replace lead pipes, install clean energy, recover from storms, and clean up contaminated land. 🔌💡 9/X

I ran $100 billion in Infrastructure and IRA programs at EPA. We obligated over $70 billion onto signed awards and contracts to protect public health and the environment. All that funding is currently frozen. Here are the facts… 🔌💡 1/X

Given the turmoil in the US research world, now might be a good time to consider making Canada an alternative place to do world leading research, esp in health. Poaching top talent currently in the US should be doable. Education and health are provincial responsibilities. Any Premiers on it?

Let them tariff our exports; we should win the war that matters, that of human capital. This is what the US did to Europe in the 1930s, building its scientific dominance on it. Oh well, a guy can dream.

If Canadian universities had a bit of vision, they would be launching a Manhattan project to poach every US-based top researcher. And the federal government would be drastically expanding tri-council funding and creating an expedited review process for those holding NSF and similar grants.

will Amazon reduce operations in Philly in response or is that just a move for Quebec locations?

One day after the White House environmental justice website went dark, please join me in welcoming the father of environmental justice to Bluesky. Yes, sociologist @drrobertbullard.bsky.social literally defined the concept in his 1990 book, Dumping in Dixie: Race, Class and Environmental Quality.

Tackling problems like climate change requires taking a stance on discounting & inequality. The literature has struggled disentangling the two. Frikk & Paolo provide an elegant solution that incorporates a range of inequality attitudes, and nests cases commonly used in the literature. Have a read!
