No doubt the NW is just in the zone right now. Every once in while we get into a regime where the mean trough position consistently remains here for two or three years. With breaks of course.
I believe it was 1C via linear regression on a 10yr running mean. By that metric we’ve observed ~ 0.5°C (+/- 0.1°C depending on the dataset) of warming since then, which is roughly half of what the IPCC projected.
However, warming was greater than predicted in the arctic, and less than predicted in the tropics (particularly in the tropical mid/upper troposphere, which suggests the positive H2O/lapse rate feedback either doesn’t exist or is substantially less than projected by climate models).
