Pictured is a graph of historical global sea-surface temperatures across the year from 1982-2024. Yesterday was about 0.3°C warmer than last year. Well, maybe it will go back down since this is an El Niño year? :>
Average global surface air temperature in February 2024 was 1.77°C warmer than the average February from 1850-1900. So maybe we can retire those 1.5°C warming goals now?
However, the IPCC reports that global temperatures have only risen by 1.1°C. This is because they use decade-long averages. Indeed, it is completely possible that 2025 will be cooler than 2024, but crop failures don't care much for averages. And if global warming has accelerated, the IPCC's method will be a decade late to realizing it. Not that they can actually do anything about it...
If you look at the scale, the seasonal variations are actually quite small. The ocean temperature was quite stable in a narrow band from 20-20.5C. Was. Water has a high heat capacity and the top few feet of the oceans is a colossal amount of water. I saw last year's rise described as "adding 500 million Hiroshima bombs of heat to the ocean." (Just normal variations I am sure, lol)
