It is not just about the present temperature and how it affects marine ecosystem or global weather. A hotter ocean fuels a few global warming positive feedback loops, like that warmer water holds less CO2, can emit more methane from the sea floor, and melts floating ice reducing Earth's albedo, and that could end warming ocean water (and the planet) even more. And that this is happening during La Niña event could turn for worse in the next El Niño.
