I just checked a physics calculator. The change from 18° to 38° means the water volume is 0.5% higher. And since there is no space but in one direction the water level is rising ... just by heat. Now 0.5% sounds not much, but imagine that for ocean-amounts of water.

@cyberfunk3793 But not while we were around and this is the problem.

@mistressfreezepeach Well then it's maybe just 0.25% for the rest of the ocean ... still not good.

@theeraphatsunthornwit6266 It's not a lie. Since ocean temperatures are extremly important for weather forcast and hurricane and storm warnings they are measured very frequently, very precise, around the globe. The North-East Atlantic is warmer than ever before. It looks like a mistake on the diagram so we are in unprecedented territory. And I only told you warmer water expands.

@InTimeTraveller Thank you all for your responses. Of course not the full ocean will heat to the levels of Florida ... not yet anyway unless we stop the trend somehow. But what is important that water expands just by heat and people forget that. This is especially important because this is not the only reason for higher water levels. There is melting ice which is on land (swimming ice does not change the level as everybody knows who had a drink on ice) which directly adds more. Greenland, Antartica and glaciers around the globe which are already receeded to large percentages. And water changes elasticity slightly with different temperatures something not even mentioned yet. It changes behaviour and maximum wave height which might be a problem on storms and for ships. Besides I never mentioned anything about how big the rise is in m or feet. I leave that to the scientists. I just gave you an orientation what water does on higher temperatures and how big it is because it is often overlooked ... sometimes with intention.

@alvagoldbook2 You missed the point: It was never THIS warm.
