I agree that whatever warming there is can't be stopped, because we can't regulate the shape of the ever-changing orbit of the Earth around the sun, nor sunspot activity ("radiation forcing"), nor the ever-changing tilt of the Earth's axis, which are the primary causes of climate change, not CO2.  Increases of CO2 always follow warming, by an average of 800 years and no less than 200 years, which a rational person would conclude that warming causes CO2 increases, not the other way around.  CO2 isn't a pollutant, it's necessary for life, and the level of CO2 in the atmosphere is coming off one of the lowest levels in the 4.56 billion year history of the Earth.  The Earth was more hospitable to life when CO2 was between 2,000 and 8,000 ppm.  Both NASA and the Navy say that astronauts and submariners are perfectly safe at CO2 levels up to 10,000 ppm, 25 times the level in the atmosphere now.  The AGW agenda is a hoax, based on scientific facts.  An Ice Age is a bigger threat.
