The area of the Arctic Ocean experiencing acidification due to excess carbon dioxide is growing rapidly. Communities dependent on shellfish and other marine resources could be at risk.
Among the changes, the Arctic tundra is now releasing more carbon dioxide to the atmosphere than it stores.
Nearly 100 NOAA scientists and staff contributed to the Fifth National Climate Assessment. Among this group were 35 authors, 13 chapter leaders, 20 members of NOAA’s technical support team, technical contributors and reviewers.
