Feng Li (NASA GSFC): Stratospheric water vapor under global warming: climate feedback and impact on temperature and circulation
Pietro Salvi (Imperial College): Time-evolving radiative feedbacks in the historical period
Andrew Pauling (Univ. of Washington): The climate response to the Mt Pinatubo eruption does not constrain climate sensitivity
09:14:55 From Thorsten Mauritsen : Interesting. I missed whether you used ocean heat uptake efficacy?
09:15:19 From Tim Merlis : Last time I checked on estimates of Pinatubo volcanic forcing there were large differences ~30% conservatively. Do you think the modelling centers prescribed the same volcanic AODs in CMIP6 like you did in the 2box model?
09:17:42 From Tim Merlis : Good news-thanks!
09:17:44 From Daniele Visioni (he/him) : Most CMIP6 models (but not all, CESM imposed their own from WACCM) imposed the same AOD from GloSSAC
09:39:26 From Isaac Held : Confused about the consistency with the first talk, since, if I understand it, you are seeing a well-defined efficacy for volcanic forcing from the historical simulations
09:40:56 From Thorsten Mauritsen : I am confused too regarding the first two talks.
09:56:37 From Cristian Proistosescu : In the efficacy terminology, the first talk suggests there is no correlation in the inter-model spread b/w volcanic efficacy and the feedback to CO2.
09:56:55 From Cristian Proistosescu : The second suggests volcanic forcing has (in the model-mean) a different efficacy from CO2
09:56:58 From Cristian Proistosescu : (I think?)
09:57:12 From Jonah Bloch-Johnson : if I understand Pietro’s talk, it looks like there’s a connection between the feedback associated with the warm pool region and the volcanic forcing efficiency - but the response to CO2 is both that feedback + feedback in other regions
09:57:27 From Andrew Pauling : Yes what Cristi said is what I was trying to say
