> I don't care if it fits your narrow definition of science.
1. That's not my definition of science--it's the definition of science.
2. If your argument is not based on science, what is it based on?
> If a planet destroying meteor is hurtling towards earth, is that reproducible or falsifiable?
That scenario would be a matter of Newtonian physics, which any astronomer could run the numbers for. Newtonian physics is indeed reproducible and falsifiable, as demonstrated by the many objects launched into the solar system, as well as the astronomical observations and predictions over the centuries.
It's disingenuous to compare climate change alarmist claims based on primitive, already-falsified computer models to simple, proven Newtonian physics.
> Should we do nothing until you personally are convinced that it has been scientifically proven that it will destroy the planet.
Should we do what you demand when you demand it because you personally are convinced that the planet is going to be destroyed? (N.B. Earth will certainly be destroyed, either when impacted by a large celestial body or when the sun expands. Earth would not be destroyed by a minor GATA increase.)
> If we convert our entire energy and transportation sectors to renewable energy and climate change turns out to be a hoax, we still get cleaner cities, cleaner air and a cleaner environment.
If it might be a hoax, shouldn't we consider why such a hoax would be perpetrated? Might there be ulterior motives? What would be the implications of those motives?
> That is a perfectly acceptable consolation prize considering the potential risks.
Your analysis presented here is completely one-sided. It does not mention any drawbacks or side-effects. It is not impartial, it is not fair, and it is not scientific. It is not a reasonable analysis to act upon, especially considering the risks, i.e. decimating the economies and lives of billions of people in poor and developing nations.
