>Carbon taxes are a fake proposed by financial elites to distract people from implementing real solutions
Taxes are a normal and widely accepted response to externalities.

>Correction. 50% of ghg are produced by richest 10% (and these people's lifestyles will not be affected by carbon taxes)
Irrelevant. Even if they don't change their behaviour, the companies they use will have to in order to stay competitive.

You first.
We can distinguish natural and human driven CO2 sources by isotope balance.

The fuck? That's politician logic.

>I can acknowledge that the climate is changing, you'd have to be literally retarded to not think there's any climate change. We can see it every day. What I cannot understand or acknowledge is that humans are somehow causing these massive changes in climate. I know that the climate is changing, but is there truly any evidence that HUMANS are the cause?
Yes. Go read the IPCC summery for policy makers.

The short version is this:
We know the planet is warming because we can measure it.
We know that the greenhouse effect is responsible, because we can observe stratospheric cooling and a reduction of outgoing IR.
We know that human emissions are responsible, because carbon fossil fuels have a different isotope distribution then carbon that was in the carbon cycle.

>Now you're just making shit up.
No.

That the current warming is driven by greenhouse gasses can be shown from studying outgoing radiation:

And that the increase in CO2 is from organic sources (ie: not volcanoes) can be shown from measurements of the C13/C12 ratio
