Note to warmist John Nielsen-Gammon: If you're trying to increase our faith in "consensus" predictions for 21st-century temperatures, this paragraph wasn't helpful

Looking Under the Hood of a Climate Model | Climate Abyss | a Chron.com blog

Testing a climate model by comparing it to 20th Century trends is fun, but not very useful for model development, because the 20th Century temperature record is just a single realization of the climate, and random variations in the atmosphere and ocean would easily make even a perfect model diverge from the observed temperature trace for years or decades. Plus we don’t know for sure what the forcing was. There’s no real ground truth.
