A climate-change attribution retrospective of some impactful weather extremes of 2021

CNDS Fellow, Gabriele Messori has co-authored a paper on the attribution of climate change to some of the weather extreme events from 2021. It is shown that the extreme events the authors investigate are significantly modified in the present climate with respect to the past, because of changes in the location, persistence and/or seasonality of cyclonic/anticyclonic patterns in the sea-level pressure analogues.
