“The periodic swings between El Niño and La Niña, collectively known as the El Niño Southern Oscillation (ENSO), is a natural phenomenon cycling every three to seven years. Over the past year, the El Niño also synced with other natural patterns like the warm phase of the Atlantic Ocean’s temperature cycle, driving thermometers up further. But humanity’s relentless injection of heat-trapping gases into the atmosphere is pushing these changes to greater extremes.”
