So you feel like your individual observations in the DC/MD/VA area validate the rejection of a global climate accord?
Unless these elitist liberals choose to sit in the dark and not consume power, walk to work (likely impossible, so maybe just not work since working also probably produces a lot of CO2) then there is no reason to attack the problem at a global or national level?
What happens to the power companies if 50% of people go on a power strike? Shut down coal plants and immediately start investing in renewable before they go bankrupt? What happens to the economy while all these liberals are putting their money where their mouth is?
Why the hell would you not push to transition from one source of energy to another without completely upending the entire system and economy? Individuals are not going to make drastic changes in their own power usage when the biggest consumers (business, industry, etc) are not going to follow and many of their fellow citizens will not follow. It would be a spiteful empty gesture (which it seems that you understand) that would just make our lives harder and damage the economy.
My guess is that your position, like most peoples position comes down to psychology. My guess is that you are a frustrated, spiteful person (at least inwardly) whose opinion on climate change is entirely emotional - people you don't respect are on one side so you are on the other. If they aren't as intelligent as you then how could they be on the right side of this issue? This is the attitude I see from most climate change deniers - initially it will be about economics, or the data (ie citing long-debunked statistics) or this and that, but eventually you get through all that and it comes down to spite.
I get frustrated by people too but I realized long ago there was no point in letting human nature (on a macro-scale) frustrate me - I might as well get mad at a pet for doing something I don't want them to do. I try to take that same mindset with climate change deniers but its hard to be so dispassionate when people are willingly making decisions like this that hurt EVERYBODY, and hurt the weakest the most just because you feel isolated.
