Hottest ocean temperatures in history recorded last year

The bad part is that the oceans are not just water, they are complicated biogeochemical systems that influence everything.

The oceans play a vital role in the carbon cycle due to a biological pumping action that pumps nutrients and carbon up and down. Climate change distrupts this process, it causes thermal stratification, which causes nutrition deficiency, which changes the plankton (including bacteria and algae) mix you get, which changes everything, but especially the atmosphere.

So it's not just water, our oceans are what makes Earth habitable. They are way more important than any stock market, and we should pay a lot more attention on them. All the attention really, we should just have an economy where performance is tied to how the oceans are doing.

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.
