Greg here shows the simplicity of the situation. He skips past the political part and lets fly the truth. The truth is, it doesn't matter whether or not we are causing global climate change or if even the climate is changing but we do know this... at the current pace, if we don't do anything, this 'cyclical' period could severely hinder the existence of the human race.
