Global Ocean Surface & Atmosphere Cools Below 30-Year Average Mean Thanks To La Nina

The La Nina came and the NET ocean heat content of earth’s oceans have cooled in the past 12 months. With this cooled, we have indeed seen the atmospheric feedback response with decline in the lower tropospheric temperature.

The atmosphere has responded and cooled to slightly below the 30-year global mean average.

The above chart represents version 6.0 of the global average lower tropospheric temperature which currently sits at -0.01C BELOW the average based on the time frame from 1979 to 2021.

The current -0.01 is down from the +0.20C of February and significantly down from around 0.6C of 12 months ago. Likely a direct response from the La Nina and probably the solar minimum.

The upcoming boreal summer season will be interesting given the weakening La Nina to see if we begin to see a rise in global temperature or do we continue with a flat line or even continued decline. As usual, only time will give us the answer.
