Beginning of semester me: *sets aside Tuesday and Thursday for research*

Me now: Spends all of Tuesday and Thursday grading and writing emails.

NSF GRFP solicitation out.
App deadlines now in November.
As others noted, eligibility rules for current graduate students now exclude 2nd year grad students. See the solicitation - they’ve emphasized “first year” and “less than one academic year” in grad program.

Reason No. 324 why no-one should think that "AI" (artificial but certainly not intelligent) is an unmitigated Good Thing: it's mathematically inevitable that AI will hallucinate.

We need far more discussion of the risks of all this and less frantic hype. I mean, really, what's the hurry?

CH₄ has a lifetime of about a decade in the atmosphere, whereby it oxidizes to CO₂ and remains in the atmosphere for tens of thousands of years. More than 99% of the cumulative climate impact (i.e., the radiative forcing) is from its life as CO₂. In the end, it's still CO₂ that gets you. 🥲

My provocation: By 2035, methane - not carbon dioxide - will be the main driver of climate change. Absent significant policy intervention, fossil fuel infrastructure will continue to emit methane at high rates even if fossil fuel combustion, and associated carbon dioxide emissions, drop sharply.

Here are 10 provocations on climate and energy. Tell me if you agree, disagree or have a nuanced take. Drop your own provocations in reply or quote post.

Start:

1. By 2030, the use of air conditioning will lead to greater increase in electricity demand than data centers. And it's not even close!

I present to you- my lab as trees.
My students said we needed “more whimsy”, so we have it now. Great summer working in mussel physiology with these awesome students

Sounds good. My own experience is that green crabs often have some blue coloring on claws and elsewhere. I’d guess is not a hybrid. But the blue is very blue and there are people who might be keen to test it out!
jbaumann3.bsky.social
Can you elaborate on the location (what bay, for example) and how common this blue morph is?

Any more photos?

This. These people assume kids do WAY more listening to professors than they do. It’s not the classes. It’s the chill AF Iranian girl with the good weed hookup and the hot queer boy who is nicer to you than any of your friends back home that change your brain chemistry. It’s the possibilities.

I used to tell biology/forestry/ecology graduate students that being a Federal Agency Research Scientist was a great career to shoot for, but they might not even exist next year.
tressiemcphd.bsky.social
But literally everything I’ve been able to tell a student for 15 years is now just…gone. Gone. I had the same issue with a family friend reaching out about scholarships to help bridge her son’s financial aid gap. I had to explain that everything I knew about is mostly gone and/or frozen.

Everyone is acting like US scientists will just go get science jobs elsewhere and sure some will but there are not anywhere close to enough science jobs elsewhere.

The end result of this will be much, much, much less science, not science happening in different places.
nparmalee.bsky.social
People are talking about the imminent brain drain of US researchers to other countries but that’s not the only way it’s going to look. There is going to be a brain drain out of science and into other US sectors. There are a lot of non-science things you can do with a Ph.D.

Read news, op-eds, and analysis, not AI summaries. Create your own art (even if it's messy) or hire an artist to do it. Do your own homework. Talk to people, not chatbots. Keep your thinking and skills sharp and cherish our messy humanity. That's the new punk rock.

Listen: this is obscenely important. There is a growing complacency that over-achieving solar can make up for under-achieving wind, and it is *not true*.

Wind and solar generate in a complementary way. Solar might max out. Wind needs much more support!!

Governments must enable faster
wind growth and increase
ambition
National targets are not ambitious enough for a global tripling, and most
countries are still not on track to deliver even these.
A global tripling of renewables capacity as agreed at COP28 last year means at least a
tripling of wind capacity. The vast majority of countries that currently have wind capacity
installed also have wind targets for 2030. However, the sum of those targets only aims for
just over a doubling of capacity, and falls short of the tripling needed to stay on the 1.5C
pathway. Forecasts for global wind capacity suggest that meeting the 2030 national targets
is achievable, in aggregate. However, this is almost entirely due to China’s dramatic rise as a
global wind leader. Without China, the rest of the world is set to fall far short of national
targets and even farther from a tripling.
Wind has an important role to play in meeting electricity generation needs associated with
the global tripling of capac

Yes. I am right. I am seeing how Chat GPT is ruining students critical thinking and writing skills in real time. It is not the future. It is a tool designed to render the populace helpless, to make people doubt their innate intelligence, and to foster overreliance on technology.

If a human told you things that were correct 80% of the time but claimed, flat out, with absolute confidence, that they were correct 100% of the time, you would dislike them & never trust a word they say. All I'm really suggesting is for people to treat chatbots with that same distrust & antagonism.

But the idea that “the product doesn’t suffer” seems so questionable. And also (per other comments) just doesn’t seem possible

Peer review is slow! This is a pre-print that is ideally in the review process now. Pre-print sharing is common in academic spheres. Though grain of salt required…

No idea if these authors have submitted this for peer review or not.

Super important point here-- privatizing GRFP or really anything funding science makes folks doing the work beholden or at least feel beholden to whatever special interest is funding. This drastically impact messaging, results, and even the questions that are asked.

And remember, they are talking about privatizing the National Science Foundation Graduate Research Fellowships, making instruments of government dependent on the largesse of the billionaire military-tech complex www.aip.org/fyi/nsf-seek...

The initiative was announced at an NSF board meeting that sidestepped discussion of looming cuts to the agency.
