Meaning there is nothing we need to do about it? It appears the deniers are heading in your direction. They are morphing from the more and more obvious lie that warming does not exist, to warming is a good thing or not important enough to worry about. It is just more denial mostly because they are too selfish to make what they perceive as sacrifices to help people that are not born yet.
Consider, what we would or could do about it, vs what will likely happen any way.
If the goal of the AGW proponents, Is to reduce CO2 emissions.
Laws passed in the US would have little global effect.
The only way to move people off of fossil fuel, it to provide a naturally lower cost alternative.
Since the technology is already being developed, and the cost curves are already converging,
Carbon neutral man made fuels, will likely start replacing fossil fuels within 10 to 20 years, likely sooner.
What we really need is an energy source, that we can store in the man made fuel.
I see the main problem with AGW, is they identified the wrong problem.
We have a very real energy problem in our (global) future.
Our modern first would life styles, are only possible with the solar energy that have been concentrated
in organic hydrocarbons. The cheap easy hydrocarbons, have already been exploited, leaving
only the expensive difficult ones behind.
Solar power (which includes wind) have an energy and density problem,
hydrocarbon storage could easily be the solution to that problem.
It would allow low density, poor duty cycle energy to be concentrated for when it is needed.
But all of this will happen without any government involvement.
When the price of oil get between $90 and $100 a barrel, it will be less expensive for the
refineries to make their own feedstock, than to buy the organic oil from the market.
The Government does need to do something, and that is unify the home power generation laws,
so they are fair for both the homeowner and the utility.
