2024 was the hottest year on record, breaching a critical climate goal and capping 10 years of unprecedented heat
CNNCNN — It’s official: 2024 was the hottest year on record, breaking the previous record set in 2023 and pushing the world over a critical climate threshold, according to new data from Europe’s climate monitoring agency Copernicus. Scientists are much more concerned about breaches over decades, rather than single years — as above that threshold humans and ecosystems may struggle to adapt — but 2024’s record “does mean we’re getting dangerously close,” said Joeri Rogelj, a climate professor at Imperial College London. “But people shouldn’t think that’s climate change hitting pause or plateauing,” said Paulo Ceppi, a climate scientist at Imperial College London. “The world doesn’t need to come up with a magical solution to stop things from getting worse in 2025,” said Friederike Otto, a climate scientist at Imperial College London.
