An excellent write-up of what will unfold.

One note is that the food loss won't just be linear. It will be chaotic within the probabilities you noted. Crop loss is effectively a weather event and, as such, a chaotic one. That means extreme events will be the driving force behind food shortages. Namely, heatwaves will cause extensive loss of crops in specific areas. Over some years, that will average down, but people don't eat long-term averages; they eat daily. So we should expect significant one-time impacts. That is, the severity is not the average but rather the peak.
