We Just Breached the 410 PPM Threshold for CO2

the IPCC models have done a good job of predicting that over the past couple decades

That's not my understanding. We had a warming "pause" from 2000 to 2010 (approximately). That was certainly not predicted.

Then scientists went back to look for an explanation of the "pause". Ocean temperature data was then incoporated, other data adjusted and the "pause" was no more.

I would characterize the climate modelling as constantly evolving. We don't have it nailed yet.

Yes, it's not settled. I suspect that the huge ramp up in SOx and particulate emissions from China played an important role. And now that China is cleaning up, reducing dependence on coal, and exporting less, the rate of global temperature increase will keep increasing.

The total energy trapped in the system was accurately predicted. The amount of heat trapped in the ocean was not so accurately predicted. The part that matters was pretty spot on.

Even more importantly, the net effects (sea level rise, etc) were well within the predicted range.

My understanding is that there is still a lot of disagreement about the adjusted data and whether it truly explains the pause.
