  • The Paris Agreement: How the World's Biggest Climate Promise Became Optional

    In December 2015, nearly 200 countries stood up in a conference hall outside Paris and agreed, for the first time, to fight climate change together. It was hailed as the moment the world finally got serious. A decade on, global emissions are higher than the day it was signed, one American president has pulled the country out of it twice, and the UN's own scientists say the promises currently on the table still add up to a planet roughly three degrees warmer.

Neither of those is a figure of speech. Both mountains are what happens when two continents meet and neither is heavy enough to sink, and the ranges they made went on to change the weather for the rest of the planet.

  • El Niño Is Back in 2026: What It Is, Why It Happens, and What It Did Last Time

    A patch of the Pacific Ocean warms up by a degree or two, and the whole planet's weather shifts. Here is what El Niño actually is, why it keeps returning, what forecasters expect in 2026, and what the last one did.
