Scientists find link between fast-melting Arctic ice and ocean acidification

An international team of researchers has found acidity levels increasing three to four times faster than ocean waters elsewhere and a strong correlation between the accelerated rate of melting ice in the region and the rate of ocean acidification. This threatens the Earth's climate and the survival of plants, shellfish, coral reefs and other marine life. The team, which includes University of Delaware marine chemistry expert Wei-Jun Cai, also identified a strong correlation between the accelerated rate of melting ice in the region and the rate of ocean acidification, a perilous combination that threatens the survival of plants, shellfish, coral reefs and other marine life and biological processes throughout the planet's ecosystem. The new study, published on Thursday, Sept. 30 in Science, the flagship journal of the American Association for the Advancement of Science, is the first analysis of Arctic acidification that includes data from more than two decades, spanning the period from 1994 to 2020.
