They blame every single change in weather on CO2 and blame climate change on every single unhappy event from Ebola to ISIS. (I am not kidding).
The Earth has been getting warmer or colder for 4,000,000,000 years. The only constant in Earths environment is change. It will continue to change till its consumed by the Sun.
Man has been on earth .00075% of Earths age or 300,000 years.
Earth will continue to change after man is long gone.
The universe is dynamic. Suns supernova, galaxys collide, planets are formed and lost in blackholes daily.
Man is merely a brief observer, not the cause.
