New record ocean temperatures and related climate indicators in 2023
Listed in National Center for Atmospheric Research
The global physical and biogeochemical environment has been substantially altered in response to increased atmospheric greenhouse gases from human activities.
Description
In 2023, the sea surface temperature (SST) and upper 2000 m ocean heat content (OHC) reached record highs. The 0-2000 m OHC in 2023 exceeded that of 2022 by 15 +/- 10 ZJ (1 Zetta Joules = 10(21) Joules) (updated IAP/CAS data); 9 +/- 5 ZJ (NCEI/NOAA data).
The Tropical Atlantic Ocean, the Mediterranean Sea, and southern oceans recorded their highest OHC observed since the 1950s. Associated with the onset of a strong El Nino, the global SST reached its record high in 2023 with an annual mean of similar to 0.23 degrees C higher than 2022 and an astounding > 0.3 degrees C above 2022 values for the second half of 2023. The density stratification and spatial temperature inhomogeneity indexes reached their highest values in 2023.
