The problem with the debate about climate change is that there seem to be 3 actual perspectives.
The first is the (typically conservative) point of view that says that climate change is less of a problem than is implied. This mentality ranges from either "it doesn't exist" to something like "we can screw off for another 100 years with fossil fuel before doing anything with renewable energy"
Then there's the liberal hogwash that climate change is going to melt the ice caps in 15 years (looking specifically at Al Gore) and that the only way to stop it is to drive a Prius and recycle. This is also equally bullstuff.
The truth is that while climate change is a very real thing, it isn't as dramatic as documentary filmmakers portray it to be. While investment in renewable energy is a positive thing, there has to be a more gradual shift to it, versus the complete cessation of coal mining and fracking that the far left proposes.
