A new alarm bell for the biosphere has just been rung.
Increased ocean acidification, a process driven by the burning of fossil fuels, has exceeded its safe limit for the first time, putting all marine life and ecosystems at risk.
Ocean acidification is the seventh of the nine natural processes that regulate Earth's biosphere to surpass their safe limits. The scientist who led this research, Johan Rockström, director of the Potsdam Institute for Climate Impact Research, explains why this oceanic limit is so important and what we must do to get the planet back on track.
