Impact of climate change on marine life shown to be much bigger than previously known

Alter and her colleagues calculated the consequences of three projected scenarios of carbon dioxide increase, and thus of ocean warming and ocean acidification: extreme increase, moderate increase at the current speed and—due to possible measures—mitigated increase.

Alter says, “Our new approach suggests that if ocean warming and acidification continue on the current trajectory, up to 100% of the biological processes in fish and invertebrate species will be affected, while previous research methods found changes in only about 20 and 25% of all processes, respectively.”
