Hmm, partly agree
In fact, I agree entirely with your perception of the tax issues, but I have to say that global warming is almost certainly being exacerbated by humankind.

Yes, the earth is in a warming cycle because of factors such as increased solar output and so on. In fact, we're actually coming out of an ice age. But if you look at the rate of temperature increase over the last 200 years, and compare this with models constructed from ice core data and the like over the last millions of years, the temperature is now increasing at an unprecedented rate.

This coincides with a rapid increase in atmospheric CO₂ content and is enough to convince most scientists (me included) that anthropogenic global warming is real.

However, on just what the consequences of that will be, the jury is still out.
