The dearth of Saharan dust this June across the tropical Atlantic is exceptional. Compare the extent to a typical June, last June, or June 2020 for a recent dusty example. Dustiness explains ~35% of SST variability in the summer so less dust generally means a toastier Atlantic. pic.twitter.com/wYbf9yKMgN
