Way back in 2013 an oceanic heatwave developed in the Pacific. ScienceAlert reports it stretched from Alaska all the way down to Mexico, and it produced toxic algae blooms, messed with oceanic ecology and caused birds that rely on fish to starve. In fact, according to Earth Data, the heatwave triggered a temperature jump in the waters off the coast of Oregon, causing them to skyrocket some 12.6 degrees Fahrenheit in a single hour.
