World's Oceans Fail Key Health Check As Acidity Crosses Critical Threshold For Marine Life
An anonymous reader quotes a report from The Guardian: The world's oceans have failed a key planetary health check for the first time, primarily due to the burning of fossil fuels, a report has shown.

In its latest annual assessment, the Potsdam Institute for Climate Impact Research said ocean acidity had crossed a critical threshold for marine life. This makes it the seventh of nine planetary boundaries to be transgressed, prompting scientists to call for a renewed global effort to curb fossil fuels, deforestation and other human-driven pressures that are tilting the Earth out of a habitable equilibrium. The 2025 Planetary Health Check noted that since the start of the industrial era, oceans' surface pH has fallen by about 0.1 units, a 30-40% increase in acidity, pushing marine ecosystems beyond safe limits.
