Spendulus, I think you're mistaking what the word falsify means with regard to the demarcation problem of science.
If you bothered to look it up, you'd see I'm stating that AGW claims are
nothing more than psuedoscience and they need to make falsifiable statements in order for us to demarcate their claims as real science or cargo cult science. That's what
falsify AGW means. It doesn't mean "disprove it" it means "make a statement that you can soundly claim with NEVER happen to support your theory".
Here's one from evolution: "We will never find modern day rabbit fossils embedded in pre-Cambrian rock."
AGW alarmists have yet to come up with one single falsifiable statement regarding man's impact on carbon. I don't doubt there is science to be had here, but it is not in making alarmist calls surrounding claims of few or several degrees temperature differences over periods of time. Instead, science is making bold claims, like "If X then Y" or "If X then not Z". Alarmists are unable to make such claims, so the only thing the rest of the scientific world can do is scratch their heads and shrug because there's not a damn thing to test or verify. This is the crux of the issue. You can't refute something that's not making scientific claims, which is why AGW alarmism has perpetuated itself for so damn long. Sure, they have a consensus in their little journals, but FFS the Vatican has a consensus on the virgin Mary! That a few individuals who choose to take the title "climatologist" decide to also be alarmist doesn't tell us anything. There weren't even degree programs for climatology as a standalone degree till 2001. It seems the required credentials for being a climatologist is that you have a degree in one of the following: physics, meteorology, biology, zoology, botany, paleontology, geology, entomology, microbiology, oceanography, astronomy, math, computer science, or statistics. I can assure anyone there is far from a consensus among those degrees on AGW, though their might be a consensus among those in those degrees that also choose to call themselves climatologists. We might agree there's been warming, we might agree that man's had some sort of an impact, but we don't all agree it's universally bad, and we certainly disagree on the level of impact. There's anything but a consensus on a single statement or claim related to AGW.
Hence my argument that we should falsify AGW claims, in other words, MAKE THEM TESTABLE.
Someone needs to make a claim that can be falsified according to Karl Popper's demarcation solution. Then we can test and/or observe.
