There is a world map in today's SF Chronicle that shows ocean surface temp rise over the last 100 years. Everywhere is colored hottter except that one patch near Greenland.
I suspect that the instrumentation wasn't very good 100 years ago. Certainly not adequate to resove fractions of a degree C.
The amount of Greenland melt water must be PPMs of the volume of the ocean, even ignoring circulation.
The map shows high water temp warming just off our local Pacific coast. I wish! Swimmers die here of hypothermia.
