Why record ocean heat does not stay in the ocean

The nonpolar global ocean recorded 100 consecutive days of unprecedented surface heat through Sept.

Cheatsheet for Why record ocean heat does not stay in the ocean. Text equivalent is attached.

Why it matters: Hotter seas can disrupt marine food chains, fisheries, tourism, coral and weather, while warmer, wetter air increases the risks of extreme rainfall, humid heat and intensified coastal heatwaves.

Open cheatsheet → Post to X

What changed
The nonpolar ocean sustained 100 record-breaking days, and atmospheric water vapour reached its highest monthly level on record in August.[1][4]
Why now
Human-caused warming is driving the long-term ocean trend, while an intensifying El Niño is amplifying heat and moisture levels.[1][4]
Watch next
Scientists expect the current El Niño to peak toward the end of 2026 and continue influencing conditions into 2027.[1]
