@leafwax @hausfath This work by @lchahn_uw suggests that part of the reason there's more Arctic warming today is that the height of Antarctica precludes deep inversions which are needed for a positive LR feedback. Antarctica without ice sheets warms mor…

For those interested in why Antarctica has a less-positive lapse-rate feedback than the Arctic, see @lchahn_uw's paper suggesting that it has to do with the height and slope of the Antarctic ice sheet precluding formation of strong atmospheric inversion…

2) Hahn et al 2020 in GRL: In a similar vein, this study show in model experiments that the orography of the AIS limits Antarctic surface warming by its influence on the vertical temperature structure https://t.co/PKsjwccDaB @lchahn_uw @karmour_uw @andr…
