Data Munching | We can't turn a blind eye to climate change when sea surface temperatures rise
Hindustan TimesMuch has been written about how 2023 was the warmest year in the world in recorded history. On January 11, data from Copernicus Climate Change Service of the European Centre for Medium-Range Weather Forecasts confirmed that 2023 was the warmest ever year on record and by a massive margin. Sea surface temperatures — the temperature of the ocean’s surface layer — across the world averaged at around 20.89°C over 2023. By itself, this number may not describe much, but what stands out is that this was a deviation of 0.69°C over what the world saw between 1982 and 2011 — the long period average of 20.20°C as calculated by the University of Maine’s Climate Reanalyser, which compiles global sea surface temperature data, as observed by the NOAA Optimum Interpolation SST V2. Thus sea surface temperatures have a cascading effect — but that's what a crisis looks like, not a single catastrophe, but a series of very unfortunate events.
