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...

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.

Alberta premier’s chief of staff criticizes new environment minister Alberta Premier Danielle Smith’s chief of staff is sounding the alarm over Prime Minister Mark Carney’s pick to head up the government’s environment portfolio.

It's a good sign when Alberta criticizes the pick for Federal minister of the environment! The opposite would be worrisome.

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...

The federal government should act decisively to modernize industrial carbon pricing Industrial carbon pricing is Canada’s most impactful climate policy, capable of driving more emissions reductions than any other policy.

The 2026 interim review isn’t fast enough to bring much-needed certainty to 🇨🇦 carbon markets.

How oil and gas methane emissions were cut in half A co-ordinated suite of provincial and federal policies has dramatically cut methane emissions well ahead of schedule. Cutting even more ...

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.

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...

If you are worried for your safety, I think there are less concerns at preclearance facilities at Canadian airports. I think at worst they turn you away (which is bad for future entry), but I do not believe they have detention facilities. This is different for crossing a land-border. Could be wrong.

I hope California's, and if not, Québec's can survive.

Protecting American Energy From State Overreach By the authority vested in me as President by the Constitution and the laws of the United States of America, it is hereby ordered: Section 1.  Purpose.

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...)

E.P.A. Is Said to Plan Deep Cuts to Greenhouse Gas Reporting Program Officials are moving to eliminate requirements that most big polluters disclose how much carbon dioxide and other planet-warming gases they emit.

(Potential) RIP to the US EPA's GHGRP! I couldn't of done of one my dissertation chapters without you. Is the NEI or TRI next? www.nytimes.com/2025/04/10/c...

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

I’m the Canadian who was detained by Ice for two weeks. It felt like I had been kidnapped I was stuck in a freezing cell without explanation despite eventually having lawyers and media attention. Yet, compared with others, I was lucky

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.

After being alerted about possible misconduct, the I4R are reproducing published papers that use data from a specific NGO (GDRI). This thread releases the first 2 reports and provides more information about the work and responses/statements from authors journals and journals. 🧵

🚨 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.

Oups! I missed the virtual😅! Sorry!

Enjoy Montréal! The city just received ~70cm of snow in 4 days. It's beautiful!
