Future Timeline

(Vox) If you were to dip your toes into the middle of the North Atlantic — say, somewhere between South Carolina and Spain — the water would feel frigid. You definitely wouldn’t want to swim. It’s winter.

Yet that water would, in fact, be very warm, relatively speaking. Right now, the North Atlantic ocean is, on average, warmer than any other time on record, running about 2 degrees Fahrenheit hotter than the average temperature over the last three decades.

To understand just how unusual this is, take a look at the chart below (and in the preceding post - caltrek). The wave of squiggly lines represents the sea surface temperature, averaged across the North Atlantic, from 1981 to now; each squiggle is a different year.
