What you really mean is that when the data doesn't support your hocus-pocus theories, instead of tossing out the theories you just invent excuses as to why the data no longer correlates.
AGW isn't science. It's a con. Aztec priests were intimately familiar with the kind of reasoning employed by their modern counterparts in the field of "climate science."
So you're saying that new evidence can't change a theory? Ever? We should stay with the way Aristotle thought the world worked?
If you can't make predictions based on your theory, then your theory is wrong. Geologists used to have a theory that the continents were fixed and immovable. "new evidence" showed that the continents did in fact move over time. Geologists then tossed the old theory on the trash heap.
We can't predict what viruses and bacteria will evolve into, but we know they evolve.
There is climate change, and it does impact storms and drought. How much and where, we don't know. How much is caused by CO2, is something we don't know either.
30 years ago, Geologists thought we'd be out of oil. We aren't. But oil is not a renewable fuel.
