“I practice hope like an Olympic sport.” –Katharine Hayhoe at @amnh.org during New York Climate Week

The fact that the thing we're calling artificial intelligence *can't do math* and yet we're jamming it into programs that successfully *have done math* for decades, then warning people against using the AI to do math, seems like an excellent summary of where we are.

Simple field test of ChatGPT 5. "Produce a table of Bolivia's largest 15 cities by population in the latest census. Provide a link to the source."

It offered the 2012 Census data, and provided a link. But each of the top nine cities has a population that doesn't match the source.

*controversy alert* if you want to move the needle on the transition I wouldn't go into physical climate science, we need folks with good quant skills in energy finance, grid stuff, transportation, etc. Like, pick one of the sectors that emits GHGs and use your physics background to help it stop

The security reason to electrify transport is not about oil imports, it’s economic resilience. Oil powers 90% of US vehicles, so when the price of oil spikes because of a war, people & companies pay more for energy, which hurts the economy. The more transport is electrified, econ security goes up.

If you don't have anyone in your feed who can bring Elton John-based biofuel diss tracks into your bsky feed what are you even doing here

Between the EU’s GHG target and policy based progress, and China’s industrial policy based progress (PV, EV, batteries), let’s all cut the BS that climate policy has vapourized somehow. North America is a sideshow now - what matter is how the Global South develops. www.ft.com/content/4abd...

Like, the damages from a middle emissions scenario, are very very bad for people, ecosystems, and the economy! If they don’t want to use the high value, use the middle one, which also requires us to get to zero emissions!

My doctrine:
Mitigate like we need 1.0°
Resilience like we’ll get 3.0°

Scientists for the past 15 years: "let's design a bunch of models & calculation procedures to estimate how much land is cleared, and CO2 emitted from land use change, when people divert food crops to biofuels and the food is displaced elsewhere"

House Republicans: "let's assume that number is zero"

Criticisms of #Wikipedia's supposed leftist bias have gotten attention lately, so let's remember that Wikipedia has also sustained a ton of criticism from progressives (thread).

US campaign entices Canada tourists: “Come visit America and also maybe El Salvador!”

A tricky thing about modern society is that no one has any idea when they don’t die.

Like, the number of lives saved by controlling air pollution in America is probably over 200,000 per year, but the number of people who think their life was saved by controlling air pollution is zero.

I kind of want to go

Scotty was the person who created the first version of the Klingon language - who set the sound pattern for it. Scotty is also from South Vancouver, right next to the Musqueam reserve where they speak Halkomelem. This is Klingon: youtu.be/-XTce38ef98?... And Halkomelem youtu.be/uy2BR0WZgrA?... 1

As a chem teacher I encourage my students to use Wikipedia, but completely discourage AI use. I have yet to find a single student who has managed to produce a text about chemistry that actually makes sense while using AI. Wiki tho? Fantastic results...

It's good that there's a 25% tarriff on imported coffee now. This will incentivize people to purchase American coffee, grown in the New Jersey coffee forests

Executive order for the “energy emergency”. The definition of energy does not include solar winds or batteries for the purposes of “emergency permitting”. www.whitehouse.gov/presidential...

In the last 30 years, almost everybody in Bangladesh gained access to basic electricity
