What this all tells us: Yes. Cool air still exists in a warming world. But it’s becoming less common. Summer cool snaps parents & grandparents once expected are now a rare treat. As the planet warms, pleasant breaks will keep fading while extreme heat keeps becoming the norm.

#hurricaneBeryl has finally weakened to a Category 2 #hurricane. #Beryl was a major (Category 3+) hurricane for 4.25 days, tied with Hurricane Emily (2005) for the most major hurricane days produced by a single Atlantic hurricane prior to August on record.
