Nature2014North America - U.S. West Coastmedium confidence

By fall 2014, the warm water of the Pacific 'Blob' extended all the way to the U.S. West Coast.

Notes on verification

Confirmed by NOAA Fisheries, NASA Earthdata, and a peer-reviewed study (PMC5703460), all consistent that the warm water mass reached the U.S. West Coast by fall 2014, with minor variation on exact seasonal onset. [tier=bronze indep_score=0.539 clusters=3 claim_tier=notable]
