William When I first came to Japan, I brought my wetsuit, which had protected me from Los Angeles’ chilly seas. On my first trip back to LA, I brought it back - the warm Kuroshio current obliviates the need for wetsuits here. And, apparently, Japan (particularly Kyushu) will see some of the greatest ocean warming on Earth. (Ironically, LA’s water is predicted to cool.)
