People living across the US have lived through some odd weather in the past year. It’s been unusually warm and dry in the western US, while the East had a very cold and snowy winter. Meanwhile, scientists have been seeing Pacific marine species in places they’re not normally found and a huge spike in hungry, stranded sea lion pups on California shores.
All these phenomena are linked to a giant patch of remarkably warm water off the West Coast in the northeast Pacific Ocean called “the blob,” a term I coined when we first started to notice it during the fall of 2013 and winter of 2014.
