As someone who drives an electric car around Texas, I can tell you that range anxiety should not be a thing anymore. There are lots and lots of chargers, particularly if your car has an adapter that lets a charge on the Tesla network.

we already had a small-ish battery but as soon as I saw how much power we were pushing to the grid I replaced it with a big battery

Turns out that kids running gaming computers 16 hours/day pull a lot of power. So now we push a lot more electrons back to the grid. 😐

We installed solar panels on our house a few years ago when my kids were in high school. The panels were sized to cover our electricity usage at the time.

Now that they've moved out, we're using 2/3rds of the electricity we previously did.

Very useful for someone like me - excited, but bewildered, by the explosion of novel approaches in the climate modeling space.

Glad to hear things are better. I was so mad in 2024 that I vowed to never submit to an AMS journal again. I even thought about cancelling my membership. But I've calmed down in the last 2 years.

I can't believe we have reached this point, but this bears crystal clear emphasis: Our global climate system ensures that even "limited" use of lower-yield "tactical" nuclear weapons against civilian or industrial targets would have major regional-to-global scale consequences.

has anyone submitted a paper to an AMS journal lately? did it get sent to the journal editor quickly?

last time I submitted a paper (early 2024), the paper spent months waiting for AMS staff to do a 15-min. check before sending it to the editor. I was absolutely outraged.

they had images from low Earth orbit, so they had a pretty good idea what the planet looked like

Excellent work here. Breakthrough has spent years doing contrarian hippie punching to get attention and their founders refuse to acknowledge how stupidly harmful that is all while occasionally pretending to have expertise in communication and public opinion.

What we are facing in 2026 is a fossil fuels crisis. Not an energy crisis. 🧪🔌💡☀️💨💧🔋

I seriously doubt the differences represent any change in the Earth. Likely it’s due to differences in the cameras and film/image processing. I’m sure that, if you wanted to, you could adjust the color balance and make them look similar.

Why is it so hard to understand
a. the difference between primary and secondary energy, and
b. why it amounts to journalistic malpractice to compare
current renewables capacity with the primary energy provided (and to a large part wasted in the form unused heat) by fossil fuels?

No, he’s not going over the carbon tax. It’s an interesting question but he’s graduating this summer and is writing this up now. He has no time to do additional work.

Prior to LLMs, I would spend a lot of time fixing grammar errors. Now, I can focus on IMHO more important aspects of the paper: is the narrative convincing, is the data analysis robust, is it well described, what are the things that reviewers will barf on and how to fix those.

I have a Masters student who’s working on this. Here is his talk from the recent AMS meeting. He’s writing this up now.

I’m just going to say it: I’ve never seen grad students (esp. foreign ones) write so well. In the old days, I would have to spend half my time reading a manuscript fixing grammatical errors. Now the papers are grammatically error-free, thanks to LLMs

Yes, I agree that a lot of people are using them but not mentioning it b/c they don’t want to be judged.

You make good points. In the end, it’s your choice. Just realize that most others are using it.

This is also a problem when working with graduate students. I can go through a document and note all of the student’s grammatical errors and they can just accept my changes and not develop their voice (or worse, learn my voice).

Obviously, this is a thread about LLM‘s and people are going to want to flame me. You’re free to do so, but I will immediately block you. You may not care, but if you do want to keep seeing my posts, then maybe just take a pass on responding. Up to you.

Put differently, the tenure & promotion committee will give you zero credit for being insufferable about LLMs.

Also be upfront with the student about the consequences: Not learning to use LLMs puts students at a disadvantage because most of the rest of the field is using them. There are lots of ways that it may hold back your career.

As usual, everyone is free to make their own decision. If you don’t want students to use LLMs, you’re free to tell them that. But don’t be a jerk about it. Using LLMs does not make someone a person bad.

I just know I’ll never tell a student to not use LLMs to 1) code or 2) help tidy up writing or 3) help them understand the peer-reviewed literature.

I do emphasize, however, that you can’t get ideas from LLMs. Those must be the researcher.
