No one (at least not anyone I know) denies that climate change through non-anthropogenic processes exists.
You are in essence though. You are claiming that natural change is nonexistent next to anthropogenic change. You (and others like you) deny constantly that natural processes account for one iota of change, or else you would mention it with any talk about climate change.
Through omission, you damn yourself.
Regardless of what the mixtures of components are, we already know now that there is no runaway warming process so the reason to fear change the way you do. We know from recent decades that CO2 levels from human emissions has basically zero effect on increases in temperature (as temperature increases have either failed to materialize or been swallowed by other climate processes even as CO2 emissions continue to rise).
So again, why do you fear? What will it take to abate the unreadable and utterly un-scientific fear of a natural process?
Instead lets fight ACTUAL pollution, lets make sane choices that are truly better for the environment and not someones pocketbook or serve to increase government power over the plebes.
