Being that you include yourself in the "we". What have you spread beyond, probably, Facebook? I doubt it's much, but you may surprise me. Also, when proposing solutions, you really need to take into consideration the "other side".
For example, telling large CO2 emitting businesses that they need to cut those emissions isn't a solution. Obviously, that's the endgame, butt hat isn't you (general) proposing a solution. A large portion of emissions comes from generating electricity... companies have for years been working to incorporate technologies that would get them to zero or near-zero emissions for their fossil fuel power plants. Problem? It is (was) extremely expensive... to capture the carbon, you're talking about building a new facility that consumes so much power that you aren't doing a lot of good in the end.
I could be wrong, but the first natural gas power plant was just recently built down in Texas. It's being used as a test and if everything goes well, they will expand. Again.. I am pretty sure this is the first of it's kind. People are working on things, but ragers want it done immediately. Shit does not work like that. I don't trust the government to regulate cap and trade systems.... California is either about to or already has passed a bill saying their state can pull tens of millions of dollars out of their emissions cap&trade market to fund other projects. That money is supposed to go towards cutting emissions -- which California is doing but not at the rate they promised when they started the programs. The government is a dirty mistress ready to infect you with an STD.
I really think the best solution is innovation, like NetPower's plant in Texas. Problem is, innovation takes time and money -- neither of which many activists want to contribute (of course, there are some). Of course, it doesn't help that the country is so anti-nuclear power either.
If you want to debate the existence of climate change, argue with yourself. I am not interested in that drivel or going nowhere conversation.
