Atlantic sea surface temperatures [SSTSST Sea Surface Temperatures] have been increasing exceptionally quickly over the last 12 months. Even allowing for the fact that the increases coincide with an El NinoEl Niño El Niño 'The Boy' is the warm phase of the El Niño–Southern Oscillation and is associated with a band of warm ocean water that develops in the central and east-central equatorial Pacific event, what lies behind them in both the North Atlantic and globally remains a mystery. As you can see from the first chart, a 365 day moving average, the linear trend since 1981 has been at the astonishing rate of +0.249°C per decade. To investigate the rise in SST I’ve developed a program to download and visualise the daily SST data from the Climate Reanalyzer site and to plot these three charts that I’ve included. I am thankful to Professor Eliot Jacobson (@eliotjacobson) for the link to the data, and the inspiration for the first two of these three charts. ToDo: It might be very useful if I were to overlay the ENSOENSO El Niño–Southern Oscillation is an irregular periodic variation in winds and sea surface temperatures over the tropical eastern Pacific Ocean, affecting the climate of much of the tropics and subtropics. The warming phase of the sea temperature is known as El Niño and the cooling phase as La Niña. events on the first of these two graphs.
As you can see 2024 has picked up where 2023 left off and is considerably higher than 2023 was at this date.
