“...exemplifies why long term predictions on climate change (involving many more unknowns and variables) are very difficult to get right. “
Don’t conflate short-term and long-term predictions. I can’t say whether or not you will be dead tomorrow, but I am confident you will be dead 100 years from now.
The ability to accurately model and accurately predict any process is dependent upon understanding the mechanisms/determinants that define that process. There are many, many more unknown variables in climate science than there are in predicting the path of a hurricane.
