nd issue a challenge to climate modelers to model and predict the behavior of the system... Then check the predictions with measurements. We need t o think of a sufficiently complex system that can be built and measured. Re member the biosphere?
Don't be silly. We aren't in the business of finding out whether climate mo dellers know what they are doing - they are just as sceptical about the res ults of their models as any climate change sceptic, with the difference tha t their scepticism is evidence-based, rather than a bought-and-paid for inc redulity purchased by the fossil-carbon extraction industry.
The trick is getting the limited amount of credible information that can be extracted from the models, rather than any kind of precise prediction.
