The giant patch of warm water in the northern Pacific – nicknamed The Blob – has finally broken up. Compare images from this year and last.

These maps show sea surface temperature anomalies in the Pacific in July 2015 (above) and January 2016 (below). The maps do not depict absolute temperatures; instead, they show how much above (red) or below (blue) water temperatures were compared to the average from 2003 to 2012.
