Observations in 2022 (IMAGE) National Institute for Environmental Studies Caption Sea surface temperatures observed in July and August 2022 near Japan and ten monitoring areas. This figure has been updated with the latest observational data obtained after the acceptance of the paper. Area numbers where extreme ocean warming events are identified are shown with area-averaged values and anomalies relative to 1991-2020. Single- or double-star marks indicate the event frequency increases more than twice or 10 times due to global warming significantly at the 95% confidence levels. COBE-SST2 was retrieved from the NEAR-GOOS RRTDB website on 15 September 2022 and thus the results in August 2022 are yet preliminary and not included in the published article.
