Exactly. And if there is so much uncertainty about the weather in a 100 square mile area over the next 48 hours, how the heck can anyone “know” what the global weather will be in 100 years?
In either the 100-square-miles or the next 100 years ... it’s all down to patterns and trends. What you say is if this pattern and trend keeps up ... “this is what will happen”. The “problem” is that you don’t necessarily know if the pattern or trend will stay constant. That’s always been the problem with predictions.
