Buried in the IPCC report are three "storylines of possible worlds"—example scenarios based on different conditions. I found it very helpful. [p. 174 on, massive PDF] http://report.ipcc.ch/sr15/pdf/sr15_chapter3.pdf#page=174
E. g. "summer sea ice has not completely disappeared from the Arctic", "the intensive area required for the production
of bioenergy sets pressures on food prices driving elevated rates of food insecurity", and "the world as it was in 2020 is no longer recognizable".
