Historical SST warming events in the Northeastern Pacific: How unique is the Warm Blob?

Abstract: During 2013-2015 a patch of warm water called Warm Blob appeared in the northeastern Pacific, producing several effects at biological and physical level. This event appears to be unique, however, evidence was encountered for another three events similar to the recent Warm Blob event during...
