Here's another way to look at how the oceans have been changing: https://www.reef.org/database-reports

 

This database has been growing for 30+ years and is approaching 300,000 surveys.

 

REEF has been responsible for this humongous (technical term) use of volunteer citizen scientists. It's probable that a lot of those here have contributed. If you haven't yet, please do! Go to the REEF.org site and find out how to sign up.

I have recently been in Roatan, Honduras, taking hundreds of photos of the reef and the current condition of many dive sites. It was depressing. Talking to the local dive masters, guides and instructors working here for years, some for decades, they said the reef is 70% dead compared to 6 or 7 years ago. I could find some isolated alive corals but not healthy at all, and the most of them are showing up massive bleaching. The water temperature was 29°C in April 2024, and increasing in summer. The problem is bigger than we think and it's worldwide.
