For the fourth month in a row global temperatures have set another new monthly record for warmth. September is perhaps the most remarkable of the four in my DIYDIY Do It Yourself global temperatures series, exceeding the previous highest in 2016 by a massive, in global temperature terms that is, of 0.24°C. The question that immediately springs to mind is when will this run of new extremes come to an end? Maybe when it comes full cycle in June of 2024, or who knows if the 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 is still running it will just continue.
Currently, on the 30th of September, the daily mean global temperature is in open water on the graph above way higher than in any of the previous daily temperatures since 1948. What’s driving the sharp rise in global temperatures are the higher than average SSTSST Sea Surface Temperatures in the central Pacific Ocean. The La NinaLa Niña La Niña is an oceanic and atmospheric phenomenon that is the colder counterpart of El Niño, as part of the broader El Niño–Southern Oscillation climate pattern. The name La Niña originates from Spanish for "the girl", by analogy to El Niño, meaning "the boy". In the past, it was also called an anti-El Niño[1] and El Viejo, meaning "the old man." event which had been keeping a check on global temperatures until earlier this year has gone, replaced by a strengthening El Nino.
