There is a severe lack of evidence to draw the conclusion that humans have caused the global warming effect. On the contrary, there is strong evidence to support that man is not responsible for this phenomenon. Ice core records over the past 650,000 years show that CO2 has succeeded temperature change. If CO2 causes global warming, how does this work?

It works that a little change of a gas, also oxygen, can cause big change in every life in earth. I recommed you to search something to the "gaia" theory, because Lovelock 40 years ago studied that we can influence changes with anthopogenic pollution, but the earth will always balance the concentrations, maybe with some difficulty, but the real problem is if we can stand this pollution, the earth will always modify itself, but only with time and preferring some species to others, i.e. when mammals are born it was because happens the biggest pollution in history of earth, the levels of oxygen increased up to current levels, but other species are extint..maybe the levels of CO2 are caused by different phenomena, but this change have, and had in history, different consequences, some of them can be prevent if their comes from human pollution, but some of them may comes from earth changes that we can't prevent..
