In 2013, a suffocatingly hot blob of water brewed in the Pacific Ocean off the coast of North America. It then decimated marine life.

Thousands of seabirds washed up dead on shores, along with starving baby sea lions. Salmon, krill, and other marine animals vanished as the warmth fuelled a massive toxic algal bloom that also shut down crab fisheries.

Confused summer breeding fish spawned during winter, while lost subtropical species such as swordfish and pyrosomes appeared far outside their normal range. Over 100 million Pacific cod are thought to have perished.
