Well, it's not like he's a professor of food with a claimed expertise in food supply chains. Go easy on him.

Now this looks useful for the Canadian climate policy modelling community, an analysis by @aleach.ca of what is actually legally allowable under Canada’s constitution … @naviusresearch.bsky.social @climateinstitute.bsky.social

For the late/west coast crowd, my latest episode where @aleach.ca and I talk about the history and economics of east coast LNG, as demands for it have been resurrected #cdnpoli

It will be up next week.

Andrew Leach @aleach.ca · 16/03/2026

I know. See my follow up. But, an NDP leader who can't win in Vancouver and who is going to scoff at the Prairie NDP types isn't going to grow the party at all. Not my circus, as you know, but the federal NDP will get what they deserve if they choose him.

Andrew Leach @aleach.ca · 16/03/2026

Of course, Shannon won't do that. Because she's actually interested in the success of the party. But, I'm going to enjoy imagining it anyway.

Andrew Leach @aleach.ca · 16/03/2026

My hope: Lewis wins the leadership, reduces the NDP to a single seat that isn't his, and I get to watch Shannon laughing exactly like this on an election night panel. If your NDP doesn't include people like Shannon, you're not going to get very far.

Andrew Leach @aleach.ca · 03/03/2026

Disagree, and I have kids and a border collie. I could be persuaded to adopt standard time permanently.

Andrew Leach @aleach.ca · 03/03/2026

How late do you wake up?

Andrew Leach @aleach.ca · 03/03/2026

There's a loud voice for this in my household.

Andrew Leach @aleach.ca · 03/03/2026

I don't think anyone is suggesting it changes the length of the day. The other option would be standard time year round.

Andrew Leach @aleach.ca · 03/03/2026

Remaining on daylight saving time would mean sunrise in mid-January would happen at roughly 9:30am. That seems like it would not be great.

Andrew Leach @aleach.ca · 03/03/2026

Especially in the context of engineering or other professional schools, the consequences of a finding of academic misconduct can be massive. Students should and generally do seek external advice, although not always from legal counsel.

Andrew Leach @aleach.ca · 22/02/2026

*waves*

Andrew Leach @aleach.ca · 22/02/2026

Okay, Bob. Whatever you want to believe.

Andrew Leach @aleach.ca · 22/02/2026

Except the fact that they are leading in nearly every poll, and recently by a significant margin, and I don't think I've seen approval polls w Nenshi up on Smith. Have you? I guess if you ignore that then you are correct, there's no indication.

Andrew Leach @aleach.ca · 22/02/2026

So, maybe go back to the original question and answer it. Is it possible that different things happen? Yes. Is there any indication that the UCP is likely to lose an election if it were called today?

Andrew Leach @aleach.ca · 22/02/2026

I'm aware of our system of government. Are you aware that polling data exists with the resolution to predict individual races?

Andrew Leach @aleach.ca · 21/02/2026

You think Enbridge agrees with you? You should take a peak at what they're building.

Andrew Leach @aleach.ca · 21/02/2026

Thanks for your input, Fred. You can protest outside with those who think I'm a climate nut.

I was going to use OPEC scenarios.

Andrew Leach @aleach.ca · 21/02/2026

See section 3.

Andrew Leach @aleach.ca · 21/02/2026

No idea what you're saying here.

Andrew Leach @aleach.ca · 21/02/2026

In the constitutional and transport sections.

Andrew Leach @aleach.ca · 21/02/2026

I do have that, including wonderful visuals from @hannahritchie.bsky.social.

Andrew Leach @aleach.ca · 21/02/2026

Yeah, have moved it up to third.

Andrew Leach @aleach.ca · 21/02/2026

What makes you think it wouldn't come up as the reason for the environmental policies discussed?

Andrew Leach @aleach.ca · 21/02/2026

I think you might want to turn it down from 11.

Andrew Leach @aleach.ca · 20/02/2026

Will be in the constitution section and in the sections on pipes and likely electricity.

Andrew Leach @aleach.ca · 20/02/2026

It's in there in session 1, but also likely in 3.

Andrew Leach @aleach.ca · 20/02/2026

Yeah, some of it although this is a good reminder to go back to Mary's book.

Andrew Leach @aleach.ca · 20/02/2026

How's this?

Andrew Leach @aleach.ca · 20/02/2026

I think the overall objective here is energy literacy. I might see if I can get sponsored by the war room!

Andrew Leach @aleach.ca · 20/02/2026

So, constitution up front? And climate?

Andrew Leach @aleach.ca · 20/02/2026

Nuclear is there for sure, as are wind and solar. Geothermal unlikely to be relevant at scale in AB any time soon. But, yes, rest of it is pretty fossil-fuel heavy, although probably proportional to its role in primary energy supplies.

000

Andrew Leach @aleach.ca · 20/02/2026

I was thinking of that. Maybe session 2.

Andrew Leach @aleach.ca · 20/02/2026

It's intended as a broad-market energy literacy course. So, I think my followers on here are likely a bit too energy-engaged on average to be representative of the target market, but I'm still interested in what you all think!

Andrew Leach @aleach.ca · 20/02/2026

It's designed for random yappers.

Andrew Leach @aleach.ca · 20/02/2026

Would you take this class? If no, why not? What's missing? What would you cut? Please share your thoughts.

Andrew Leach @aleach.ca · 20/02/2026

Is there any polling showing that an election would be remotely close?

Andrew Leach @aleach.ca · 20/02/2026

I think you've answered your implicit question.

Andrew Leach @aleach.ca · 20/02/2026

I think we might see another question or ten added before we get to the fall.

Smith kicked off the sovereignty referendum campaign tonight. The fight for the future of Alberta starts now.

Good read from @aleach.ca on the oil market and the case—or lack thereof—for a new pipeline. Puts some good context into the talk of Keystone XL revival or Ford's west-east pipeline study.
