Climate change even when natural has a trigger. The earth doesn't wake up one day with a wild hair up it's arse and decide to change the game. The Milankovitch cycles ain't due for another 29,000 years, no super volcanoes, or large tectonic shifts recently. However we are pumping ungodly amounts of greenhouse gas into the atmosphere.
It's not even complex science that everybody tries to make it out. The global climate is easy to model when only three basic factors are involved. Anyone who is a sceptic on man made climate change needs to take a step back and look at what really dictates the earths temperature.
For the record I know perfectly well that we're never getting off fossil fuels. They will be gone someday possibly in my lifetime, and it might be a good idea to advance Americas natural energy potential. If we did come up with a way to provide cheap clean energy it would be a game changer for the whole planet. Imagine how much you're quality of life would go up if you never had to pay a electric bill again. I don't get why anyone would resist the advancement of the human race.
