We have exceeded 1.5c warming.

"I think it's safe to say that both 2023 and 2024 temperatures surprised most climate scientists - we didn't think we'd be seeing a year above 1.5C this early," says Dr Hausfather.

"Since 2023 we've had around 0.2C of extra warming that we can't fully explain, on top of what we had expected from climate change and El Niño," agrees Helge Gößling, a climate physicist at the Alfred Wegener Institute in Germany.
