Acidification of the western Arctic Ocean is happening three to four times faster than in other ocean basins, a new study has found. The ocean, which absorbs a third of all of the carbon dioxide in the atmosphere, has grown more acidic because of fossil fuel use. Rapid loss of sea ice in the Arctic region over the past three decades has accelerated the rate of long-term acidification, according to the study, published in Science on Thursday. https://www.theguardian.com/environment/2022/sep/29/arctic-ocean-acidifying-up-to-four-times-as-fast-as-other-oceans-study-finds
