Taking into account all known factors, the planet warmed 0.2 °C more last year than climate scientists expected. More and better data are urgently needed.
We need answers for why 2023 turned out to be the warmest year in possibly the past 100,000 years. And we need them quickly.
Could be an anomaly on top of climate change but as far as we know it’s probably hard to tell. We’ll probably understand it better in a few years.
