From the Ted Talk by Jeremy Jackson: How we wrecked the ocean
Unscramble the Blue Letters
The really scary things though are the physical, chemical, oerhanapgicoc things that are happening. As the surface of the ocean gets warmer, the water is lhitger when it's warmer, it becomes harder and harder to turn the ocean over. We say it becomes more strongly stratified. The consequence of that is that all those nutrients that fuel the great aecvtnoha feirheiss, of the sardines of California or in Peru or whatever, those slow down and those fisheries collapse. And, at the same time, water from the surface, which is rich in oxygen, doesn't make it down and the ocean truns into a desert.
