I'm not too concerned about it. It's one of those things that's so far outside my control that there's nothing I can do about it.
Our politicians want to make us scared of it so they can "fix" it. Fixing it takes money so of course they need to tax us some more.
For instance our President has decided that coal is evil so is going to shut down the coal industry. "Utility bills will necessarily skyrocket?" Do you recall that speech? Of course they tax our utility bills so more $ to the gov.
The real problem is overpopulation by humans of the planet. I suspect our kids will have far bigger problems to tend with than global warming.
