Make a prediction model, plug in the data and release the results to the public. Prediction turns out to be wrong, rinse and repeat
That’s not far off liberal scientific methodology, to be fair, but it seems to put the cart before the horse. You might want to look up ‘falsifiability’, ‘confidence factors’, and, if you have the time and inclination, Karl Popper’s Objective Knowledge.
This won’t give you everything but it should go some way to explaining the scientific method in more detail.
The process is roughly as follows:
The more times the hypothesises is not disproved, the more likely it is too be correct, the more confident the prediction. According to this theory, it’s impossible to prove anything; we can only be confident that knowledge is objectively true if we have tried and failed to disprove it. This is a bit of a blunt summary.
If you don’t trust this method, I wouldn’t ever get on a plane or take any medication.
The key point being that a prediction won’t become the consensus until it has a fairly high confidence factor (i.e. lots of people have tried and failed to disprove the prediction). Climate change is one of those things. Every time someone conducts another experiment, the new data strengthens the view that global warming cannot be disapproved.
Just to put all my cards on the table, I think Popper is wrong. But he sets the scene for a lot of liberal conceptions of science. It’s his ideas that underpin many of the kinds of predictions that you’re talking about, I think. (When I say liberal, I’m referring to the main ideology of capitalism, not to the ‘left’ brand of US politics.)
That is, climate change about as ‘true’ as things can get, and so it is predicted. But even ‘prediction’ in this sense, makes it seem as if we’re taking about something in the future (I couldn’t help but challenge the Popperian model just a little bit, I’m afraid). But climate change is already here. It’s the present. The prediction only concerns how bad it’s going to get.
Thanks for this write up and the Popper reference!
You’re welcome.
Feel free to come back if you want to talk about Popper more. His work can be quite difficult to read. Some paragraphs/chapters read smoothly, then others are very technical. It might be worth having a quick look into ‘hypothetical deductive methodology’ for an overview of Popper’s main idea before tackling him directly.
It might also help to know that his theory comes from his anti-communism. So when he’s talking about the problems of prediction and historicism, he’s challenging the Marxist method (poorly, IMO, but I won’t get into why, here, unless you want to talk about it).
