Abstract/Summary

In 2022, the worldwide averaged satellite-derived lake surface water temperature (LSWT) warm-season anomaly was +0.33°C with respect to the 1995-2020 baseline, the second highest since the record began in 1995. The mean LSWT trend between 1995 and 2022 was 0.20±0.01°C/decade, broadly consistent with previous analyses. The lake-mean temperature anomalies were positive for 70% and negative for 30% of the 1951 globally distributed lakes. For about 30 other lakes, no anomalies could be computed since no water was found in 2022. Large regions of coherently high LSWT anomalies were identified in 2022, with 40% of the observed lakes experiencing LSWT anomalies in excess of +0.5°C.
