This is the BlueSky feed of Raymond T. Pierrehumbert, Professor of Planetary Physics at the University of Oxford. Tune in for news about Principles of Planetary Climate, and diverse science and political commentary. (Also folk music news)
As seen on a lawn in Madison, WI. (Needs to be updated with the lone-star tick, I guess)
Stirling Air engine. The rotor is moving so fast you can't see it moving, but you can hear it, and see the flashing light powered by the itty bitty generator it runs. If you extinguish the flame and crank the rotor instead, it acts as a heat pump. The working fluid is plain old air.
Agreed. Me, a considerable number of years ago, Abisko, early Spring. -28C outside, -6C inside, but I still felt drained when I got back.
Edouard Barrier: Effect of hazes on surface temperature of subNeptunes
Robb Calder (invited presentation): Most subNeptunes observed so far have magma oceans.
Namrah Habib on subNeptune convection at high resolution, incorporating compositional buoyancy effects:
Joseph Livesey on how tidal heating restricts habitability of subNeptunes:
Cara Pasciotta shows how hydration of hazes in water-rich atmospheres changes their optical properties:
gear on top and they'd still be intact after a week. I haven't seen Voima around for a while.
additional kneading. A bonus is that you can control the amount of salt -- commercial bread, even the expensive boutique stuff, tends to have a ton of salt. Wonderful to be able to produce such a beautiful nourishing thing with only the most basic gear.
And this bit of hype now appears at the bottom of the Google search page. Yeah, right; more like "Destroying the environment through witless expansion of useless AI."
New Years Eve, ski trail at ABR in Ironwood, MI. Best snow I've had my skis on in several years, including our last spring ski trip to Äkäslompolo.
Very interesting piece on the work of a (formerly) Oxford seismologist on soils. In honor of George's interest in soils, I'm re-upping the Antigo Silt Loam song.
Congratulations to Dr. Richard Chatterjee, my DPhil student who passed his viva on atmospheric escape today and is off to a position at Leeds. (Me on the left, his examiners Garcia-Muñoz and Tad Komacek on the right -- Tad and Richard are in the traditional subfusc, except should be white tie)
Yikes, this last one takes the cake for getting it in just under the wire, practically to the millisecond! And so to bed. (Time zone Oxford, 1AM = 8PM EDT)
Breaking: MIT president Sally Kornbluth decisively rejects Trump's coercive "compact" for higher education. Here is an excerpt from her letter, following on a description of the principles by which MIT has already abided. I'm proud to be re-joining their faculty in 2026.
Following up on this thread, something that might not have been clear from what's in the paper is what's going on with the bare rock vs. rock vapour case in Fig. 2, so I'll add some additional explanation here.
Our other piggy, SeitaPirtti, also got along well with Rob's piggies, but wasn't in the pictures. Here she is:
