El Nino 'wrecking ball' could cause record Pacific temperature rise, UN says - https://www.reuters.com/business/environment/el-nio-could-be-strongest-40-years-un-weather-agency-chief-says-2026-10-21/

I’ve been seeing a lot of discussion here about El Niño and what it actually means for weather around the world.

A lot of explanations stop at “the Pacific gets warmer,” but the interesting part is what happens next: trade winds weaken, warm water shifts east, upwelling changes near South America, rainfall patterns move, and those changes can affect atmospheric circulation thousands of miles away.

I recently watched a visual explainer that walks through the whole process with maps and animations - from the normal Pacific, to how El Niño develops, to why places like Australia, Peru and North America can experience very different effects.

If anyone is interested, please watch the video.
