Atlantic Reefs’ 2040 Tipping Point

Updated: 2025.10.13 8D ago 2 sources
A study of 400+ Atlantic reefs estimates that over 70% will begin dying by 2040 even under optimistic warming, and 99% will stop growing if temperatures exceed 2°C by 2100. Reef loss would gut marine biodiversity and remove natural coastal defenses, shifting risk onto fisheries, tourism, and shore communities. — It reframes near‑term climate policy as a coastal infrastructure and food‑security problem, not just a distant biodiversity concern.
