The IWPR link from above (with data from the US BLS) suggests that the 320K women in construction trades represent 4% of the total field, implying that there are about 8 million total construction trade jobs in the US. I'm not sure how many construction workers hold 4 year degrees, but it seems plausible this would explain a large portion of the gap.
No, it shows that all trades jobs put together make up about as many jobs as nurses OR teachers. This is some basic media literacy that needs to be used when media outlets like the Wall Street Journal publish articles suggesting that all unemployed Americans should just become electricians. (or whatever other trades job they trot out) These jobs can be lucrative for men without a college diploma but are a small fraction of jobs in the USA.
Steel uses so much carbon that it’s been a target for using hydrogen as a reducing agent. There are a couple ironworks that have already started converting.
That’ll still leave concrete as one of the next largest sources, even if the rebar gets a smaller footprint.
That would be true if there had been zero effort and money spent in subsidizing fossil fuels, hiding data about its true long term impact for decades and sabotaging efforts to move away from carbon dependence.
There are two types of coal, metallurgical and thermal.
Energy for steel production can come from coal, but doesn't need to, coal bound with iron to make steel is a different reaction to burning coal for energy.
"Green steel" (as odd as that sounds) is an active area of research ATM, promising but there's a looong way to go to reduce the emissions from a billion+ tonnes of steel per annum (and concrete production and other resource processing).
One of the biggest Steel mils here in Argentina had a dedicated forest with 30.000.000 eucaliptus to make the coal. So it's possible to use carbon-neutral coal. More details (Spanish) https://es.wikipedia.org/wiki/Aceros_Zapla_S.A.
Yes. Already during the Roman empire the Ruhr valley was denuded as the trees were cut down to make charcoal for iron making.
With modern technology we can do better, e.g. torrefaction produces bio-coal with about 90% of the original energy in the wood, but OTOH the scale is way beyond what was seen in the ancient world.
They will never be a state. They’re in the sweet spot of self governance and endless federal subsidies. Despite what Wikipedia will tell you, English is not prevalent. Statehood will never happen and I’ve been listening to that drum for over 30 years.

Let's be clear, this is not decided by Puerto Ricans. Congress ultimately decides this. How they decide is up to them. Until now, they haven't done much.
Jones Act restrictions on shipping are a lot worse for them than any amount of subsidies. Makes it much harder for ships to come from nearby non-US islands and deliver anything.
I recently switched back to using homemade desktops for most of my work. I’ve been running Debian on them . Still have my Mac laptop for working on the go
hcaptcha cofounder here. Whenever i read these stories and papers they never talk about how captchas have different difficulty levels or what level they were using. I assure you we've been using LLMs since before transformers in the captcha industry and we can catch and defeat them all at the correct difficulty level
You are telling me your students can safely implement single decree paxos.... I worked on a few paxos production implementations before the RAFT paper, single and multi decree. The idea that paxos, as it is to be implemented, is easy for students to understand... Well let me re-read the paper, but i assure you, raft was a big deal
