I’m in NYC preparing for civil disobedience this morning, which is to say, I’m acting out of my conscience and sense of obligation that comes from what I know as a biologist. Today my body is a data point. And it’s full of love and resolve. #SummerOfHeat My statement:

#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.

Models have overestimated atmospheric levels of hydroxyl radicals, which break down methane. A new discovery shows that water vapor reduces sunlight's availability to make hydroxyl radicals, slowing methane’s atmospheric breakdown rate. climate.gov/news-features/…

🍂 Aug-tober? From the Upper Midwest to the Southeast, many are stepping into refreshingly cool late-summer air this week. 🔵 Temps 10–20°F below average—a rare late-August treat The catch? A refreshing summer cool down like this is becoming less common for future summer fun 🔽

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.
