@alexandreshields.bsky.social je crois que ce nouveau cahier de recherche (de @eyalfrank.bsky.social et al) sur la réduction des risques d'accidents de la route grâce à la présence des loups sur la rive nord versus sud du Saint-Laurent saura certainement vous intéresser: www.nber.org/papers/w34377

So for-profit AI companies have trained on the world's largest collaborative volunteer project and a precious free resource, to make money for their for-profit enterprises. They have crushed traffic to the volunteer project, starving it of donors and volunteers www.404media.co/wikipedia-sa...

OK, here we go... I'm excited to launch Climate-Colored Goggles, a newsletter about climate and culture. I'll be writing about climate solutions in pop culture, media & sports. America's most influential storytellers need to get in the game. Sign up here: www.climatecoloredgoggles.com

The only questions you ever need to ask of people who want to peddle this issue are: "What do you mean by merit? How do you measure it? Is there only one definition of merit?" They will not be able to answer The Qs because they haven't thought about it. Because, in turn, IT'S NOT ABOUT MERIT.

We have had this precise discussion many times before, with the invention of the book, radio, TV, the internet, etc. Knowledge of these discssions are freely available, but apparently the WSJ can't find it or doesn't understand its relevance. Might this kind of thing be what professors are for?

You might think that the mayor of Yellowknife, the capital of Canada's vast Northwest Territories, would be a fan of giant pickups. Nope. He's disgusted by car bloat. www.linkedin.com/posts/benjam...

On Sunday, #Zürich residents voted 52.8% in favor of increasing parking fees for cars according to weight. The owner of a BMW X2 (Diesel), which weighs 1,675 kilograms, will now pay equivalent of €717 Euros per year to park on a public street. (Before, about €321.) Direct democracy!

Noise reduction benefits from EV adoption in the US estimated at $77.3 billion, concentrated among low-income families in urban areas www.nber.org/papers/w34298

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!

#cdnecon do I spy @mikepmoffatt.bsky.social au discours du Trône?

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-...

A PhD economist as the Prime Minister of Canada: "So I'm going to govern in econometrics"

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...)

(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

Adding CBC News to my daily reading (which includes The Guardian, Boston Globe, Philadelphia Inquirer) Mourning the loss of my lifelong standbys, now sane-washing a rapid slide into autocracy RIP Washington Post, NYT, LA Times

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...

🚨Incredible lineup at @nber.org conference this Thurs/Fri 3/20-21: **Energy Markets, Decarbonization, and Trade** 📑Agenda www.nber.org/conferences/... 🎥 Webstream www.youtube.com/nbervideos Organized w Natalia Ramondo, supported by @sloanfoundation.bsky.social

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. 📝 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
