Are you referring specifically to climate as in weather? The article is about forecasting a range of future events, not specifically weather.
But our ability to forecast weather on a longer timeline, like for industrial forecasting, is calibrated on historical weather patterns. But with weather being more erratic and unusual, I don't understand how AI will be forecasting with the models they have now.
For example, predicting which party will win an election, or if there will be a major cyber event in the next year, or the price of Gold in 6 months. Presumably a few of the questions could be related to climate as you're thinking of.
