At the bottom: Is climate change affecting La Nina’s impact?
El Nino and La Nina are now happening on top of the effects of global warming. That can exacerbate temperatures, as the world saw in 2023, and precipitation can go off the charts.
Since summer 2023, the world has had 10 straight months of record-breaking global temperatures. A lot of that warmth is coming from the oceans, which are still at record-high temperatures.
La Nina should cool things a bit, but greenhouse gas emissions that drive global warming are still rising in the background. So while fluctuations between El Nino and La Nina can cause short-term temperature swings, the overall trend is toward a warming world.
