Predictions are still plus or minus 1000 years or 10,000 years. Maybe over a thousand years we should consider where we live, more north or more south.
The next 100 years is pure speculation, pessimism, optimism.

I am 99% certain we will start to have food problems because of cold in the next 20 years, and we will be in a mini-ice age within a 100 years ahead of the full iceage that is coming after that.
