A simple case, indeed–an oversimplified, cleverly designed false analogy. The problem, of course, is that, unlike in your example, there are not millions of people who everyone knows have a thorough mastery of how the climate responds to stimuli such as CO2, with the ability to pass operationalized, predictive tests. Likewise, Googel Translate, unlike the models in climate science, can also pass operationalized, predictive tests. For example, if I use it to translate “I want fried cat” from English to Korean, I may not end up eating cat, but it won’t be because the waitress didn’t know what I was saying (or at least what was on my slip of paper–the output of my model).
