The earth goes through cycles of hot and cold similar to the summer and winter seasons - hotter than blazes for a while, cold and frozen for a while. There is nothing that you, I, anyone, any government, or any group can do about that - no matter how much they care.
Other than caring and spewing rhetoric I see no real action being taken by those same individuals. No trees planted, still driving cars, still buying synthetics produced with fossil fuels in fossil fuel powered factories, still producing large volumes of trash, still recycling (which does nothing to help the environment), still consuming electricity to power lights, computers, cell phones, still drinking the kool aid of fear being put forth by doomsayers.
You are being conditioned and terrorized by the eco-prophets to surrender your ever diminishing freedom in exchange for "salvation". Division completed, conquering to follow.
