I know it’s not that simple (you have to listen to her)

academic job ads are all like "we seek the smartest person who has ever existed, duties involve securing millions of dollars of grant money to pay senior administrators and teaching 70 classes. we will pay you one (1) dollar and give you access to the library on alternate Tuesdays

this is not directed at program officers who are wonderful, overworked, and should fund everything I send them, but rather their politically appointed bosses

to be more realistic we could rank students by interest/ability, identify the ones at the bottom, and ask the principal to put them in charge of everything

this is a good kindergarten activity, but I feel the fifth graders need something more engaging, like fixing the indentation errors in their current and pending funding table

I have to do Career Day at my kids' school, what's a good way to teach them about science? I was thinking of giving them a fun activity and then making them fill out a lot of paperwork before abruptly canceling it

are you a giant nerd who wants to know what past temperatures and precipitation totals are compatible with tree ring based drought atlases? Me too!

Things I learned today - language in the Clean Air Act explicitly defines "air pollutant" to include anything with adverse effects on weather and climate

NCAR and the climate and weather services it provides are a classic example of a public good. These broadly support other sectors of the economy and will not be provided efficiently by the private sector. Critical case in point - insurance pricing

we explained all of this in the Fifth National Climate Assessment, an official document that went through exhaustive peer and National Academies review, responded to comments in a transparent process, followed all relevant federal advisory committee rules, and has now been replaced by Grok and vibes

But it's fascinating to look at where we are now compared to our history. And remarkable how many of those changes we completely understand.

Climate "skeptics" are indeed correct that not every extreme event is 100% attributable to climate change, and that bad things have happened in the past. Although I don't think "climate change will only be as bad as the Dust Bowl, forever" is quite as reassuring as they think it is

the trend in humidity is much clearer, for example

And this is because basic physics says that warm air can hold more water vapor, that can be dumped on us in the form of heavy rainfall

but where you REALLY see the trend is in *extreme* precipitation. It may or may not be raining more on average, but when it rains it pours. The changes in heavy rainfall are very noticeable:

ok what about precipitation? It looks like it may be increasing, if you squint, but the upward trend is not nearly as clear as in temperature. We expect that average rainfall worldwide will increase a little with warming, with lots of regional variations

This is the difference between daytime and nighttime temperatures. Nights are warming faster than days, which is 1) a smoking gun that climate change is not caused by the sun and b) bad

This is for the whole country. If you just look at the West, the 2000-2022 drought is by far the worst on record. And it's the worst in at least 1,200 years
