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.
I though it was believed to be due to the rapid phaseout of sulfur in marine shipping fuel?
This was my understanding as well. Basically we were accidentally performing climate engineering and then we stopped so things went back to reality
