It's just a lag really.
Takes a while to warm the oceans, which is why even if we had net zero emissions tomorrow things would continue warming for decades.
Usually there's several years of warming to hit a new baseline and then it levels off for a bit or may even go down in lieu of other factors like in the 70s.
Then the process repeats. Note that the leveling off period is what climate skeptics always mention. They talked about it in the 70s and 00s.
The skeptics will also return if/when we do get net zero emissions and the planet continues warming. They refuse to acknowledge the lag.
