Discovering ancient climates in oceans and ice

The swift change in ocean chemistry outpaces marine organisms' ability to adapt, rooted in millions of years of lower CO2 levels.

To safeguard oceanic biodiversity, immediate action is needed to limit CO2 emissions and mitigate the dire effects of ocean acidification.

Ocean acidification, a dire consequence of CO2 emissions, threatens marine biodiversity and necessitates urgent CO2 caps.
