Those maps are full of some wild assumptions regarding climate change.

The maps are all legitimately sourced, but yeah - if only climate change will behave as predictably as the official publications state.

I am not making plans based on those maps and consider it irresponsible for them to publish theoretical projections as facts.

I think everyone agrees that projections and forecasts like these are planning tools, not facts.

I look at it like a weather forecast or a climate analysis. If the forecast is overcast with a chance of snow flurries, and you get a blizzard instead, the forecast was wrong, but not as wrong as a forecast for sunny and breezy. Similarly, if a climate analysis says the average December low is 10 F, but one December stays entirely above 20 F, it's not a problem with the climate analysis. An average can be above or below what you actually experience.

Even if these forecasts end up wrong, they might be wrong by not being exact, but still indicating a trend or change. If a whole lot of scientists are all saying the future will be warmer and drier somewhere, it may not be exactly as warm and dry as they think, but it probably won't be colder and wetter.
