Slow? Slow compared to what? Reality is not slow, or fast or anything. Reality is what it is.
Yes, it’s slow compared to the ’90s. So? That’s ‘slow’ only if you expected it would continue to warm at the same rate.
It’s also slow compared to the models. That’s not ‘slow’, that’s the models being fast. The models are hotter. And the models are definitely man-made.
So yes, it’s not the climate that’s slow.
It’s the models that are hot, and your expectations that were high.
