The problem though is that things are getting worse not better. Globally emissions are increasing, not decreasing, and unless something is done relatively soon (especially given how slowly we as a species tend to react to such stuff), we will hit the tipping over point which would be catastrophic for our species, and many other species that we share the planet with.
Worse though, the closer and closer we get to the tipping point, the more extreme the change would have to be to counter it, and the less likely we are to implement it in time.
Anyhow you guys are using a whole wack of different fallacies (false arguments) in your statements (strawman, ad hominem, tu quoque, red herring, and several others).
