Upper environmental <i>p</i>CO<sub>2</sub> drives sensitivity to ocean acidification in marine invertebrates

Nature Climate Change, Published online: 03 February 2022; doi:10.1038/s41558-021-01269-2

The authors link the effects of pCO2 on marine invertebrates to the localized pCO2 conditions of their coastal habitats. They show that responses depend on the deviation from the locally experienced upper pCO2 level, highlighting the importance of small-scale variability and adaptation.
