World’s largest coral reef system off Queensland, a World Heritage site
The latest data show global sea temperatures have reached record highs in August 2026 as El Ni 0o intensifies, driven by natural variability and long-term warming. Forecasts indicate the warmth will continue into 2027, with wide-ranging impacts on weather, seas and economies. Governments warn of increased risks to vulnerable communities and fisheries.
Whale sharks, the world’s largest fish, have been spotted near the Hudson Canyon about 100 miles off New York, with NOAA considering a National Marine Sanctuary designation to protect the area. The sightings come as warmer Gulf Stream–driven currents draw tropical species closer to metro waters. A 24-hour pelagic trip captured the moment, while researchers note the species remains endangered and face ongoing threats.
The IUCN has classified 96% of the world’s shallow-water coral reef systems as critically endangered and warned of possible ecosystem collapse by 2075 if current warming continues. The assessment, presented at COP17, blames heat stress from climate change and adds that reefs still show pockets of resilience that stronger emissions cuts and local conservation can protect.
