More context [1]. This was measured in very shallow water with poor circulation and heavy dark algae (which heats water) and is also similar or less than readings in 2017 and 2009.

> Even if the 101.1° water temp isn’t verified, it was exceptionally hot in the Florida Keys, and it remains that way.
> Water temperatures at other buoys, and remote sensing using satellites, have recorded water temps in the mid to even upper 90s around the Florida Keys.
> This has resulted in brutal heat for the land areas.
It may be that the Manatee bay sensors are in a uniquely hot location but the temperatures there will be negatively impacting wildlife; outside that location water temperatures seem pretty darn elevated.

Coral bleaching isn't typical and is a direct indication of water temperatures exceeding the max habitable temperatures. You can look at coral, or manatees, or algal blooms to confirm that our present conditions are anomalous. Extraordinary claims require extraordinary evidence but the research is in regarding rising sea temperatures.

The best we can say is, “at least this is the best time to be alive for humans”.
