They don't know what the model's accuracy is over long periods because it hasn't been around long enough to test.

- brabel 6y agoWhile you can never be sure, you can apply your model to the past and see if it can predict the present.

- orwin 6y agoWell, i think the (honestly quite basic) climate model that came into being in 1974 is 95% accurate then, since it predicted the rise in average temperature until 2020. What climate modelists do is take the data from 1950, put that in their models, and see how well ir predict the temperature and hydrometry of different areas. I think what they were working on in the 2010s was how much the artic polar circle was at risk of breaking more often, and what that would mean for the average temperature (not much) and precipitations (probably drier winters/springs in europe). Sadly they did not amke prediction about how much the polar winds descending south would kill buds and take a toll on orchards.
