In Earth Science (or at least in cimate/atmos/ocean) there is no particular significance to last author. The senior author (PI) is often second author, but just as often will be in the middle of the list.

Chemistry is really not my strong point, but, generally speaking, if you have a source of particles how can they neither accumulate nor interact (i.e. be inert)?

Like, I get it how evolution and natural selection worked to select for humans whose brains cannot just tune out their kids’ screaming. All i’m saying is that once you introduce the interstate highway system you run the risk of starting to naturally select in the other direction.

The ACE2 emulator is only trained historical AMIP simulatotions. Yet, it reproduces patterns of response to localized warming! Check out the stationary waves propagating from a Warm Pool SST anomaly. These are not explicit in the training set, and I doubt ACE2 read Hoskins and Karoly 2/

ECS <2 is absurd in the year of our lord 2025. The data used in Sherwood et al is now almost a decade old (not to mention Lewis and Curry 2014). Even ignoring pattern effects, we’re now already at ~1.5C with less than 2xCO2 and an even larger energy imbalance. No way Effective ECS is <2.
