Mann's False Hope Graphic Presentified

I needed a copy of the “False Hope Graph” that Michael Mann painstakingly created for his Scientific American piece “Earth Will Cross the Climate Danger Threshold by 2036” for a presentation I’m doing, but it had to be simpler, leave some stuff off, and be readable across the room on a screen. The original graphic looks like this:
earth-will-cross-the-climate-danger-threshold-by-2036_large (1)

It is a major contribution showing the relationship between climate sensitivity and climate change in the future depending on various important factors. The graphic I made from it is here (click on it to get the big giant version):

You’ll notice I left only one sensitivity + aerosol forcing line on it because in my talk I’ll use that as the most likely. Some of you might find it helpful.
