09:32:41 From Shiv Priyam Raghuraman : Great talk Daniel! Any thoughts on how to include clouds into this analytical framework? I think the IPCC estimates are all-sky estimates
09:36:45 From Jonah Bloch-Johnson : the “feedback CO2 dependence” that Daniel describes is actually the same physical mechanisms as the “forcing temperature dependence” from He et al. 2022 (https://arxiv.org/abs/2210.12244)
09:37:38 From Kyle Armour : Thanks, Jonah, I’ll check that out as well.
09:38:25 From Daniel Koll : Replying to "the “feedback CO2 de..."
that’s correct, Jonah, although feedback CO2 dependence is not the same as the CO2 feedback which Kyle was asking about (which is the feedback that comes from the part of the spectrum which is dominated by CO2)
09:39:15 From Jonah Bloch-Johnson : Replying to "the “feedback CO2 de..."
ah, gotcha
09:39:36 From Daniel Koll : Replying to "the “feedback CO2 de..."
For how CO2 can act as a feedback, check out Seeley & Jeevanjee’s 2020(?) radiator fin paper.

Here’s the link: https://doi.org/10.1029/2020GL089609
There is some additional discussion also in Lukas’ paper https://doi.org/10.1029/2021GL094649
09:58:26 From Bjorn Stevens (MPI-Hamburg) : There is also the nice connection to Daniel’s talk on that last point (subtropical cooling)
10:01:28 From Stephen Po-Chedley : Is the global average warming (HR versus LR) approximately the same in 2100? It looks like it.
10:02:14 From Nic Lewis : Pedro, as the ECS of the high resolution model is similar to that for the standard model, at what point do their warming patterns converge, if at all? Thanks
10:04:18 From Nadir Jeevanjee : I guess the TCR of the two configurations might be different?
10:04:29 From Stephen Po-Chedley : Great talks!
