More accumulation

Rising ocean temperatures have been in the news recently, with unusual fish sightings (1) and catches (2), and satellite images (3). The world’s hemispheres have alternative summers and winters, so oceans warm up half the year and cool down the other half. The sun heats them and the heat is dissipated by vast ocean currents and by incoming winds. Until recently the hot and cold balanced out, what was gained in summer was lost in winter. This equilibrium seems to be broken, and every year the temperature rises as less heat is dissipated and more is added. Such an accumulative process could bring severe climate change (+2/3°c) forward into the coming decade.
