Global warming has accelerated, a lot! The first 19 days of 2025 were on average +1.74°C above pre-industrial. That's about 0.1°C warmer than the same period last year. Then we had an El Niño, now a La Niña.

In case you had any doubt, the near perfect fit of the quadratic trendline makes it clear: global sea surface temperatures are accelerating. The current rate of warming is about 0.32°C/decade, which comes out to somewhere around 275 million Hiroshima bombs worth of ocean heating in 2025.
