Carbon dioxide levels today are nearly 30% more than they were prior to the industrial revolution. What is truly unprecedented about current carbon dioxide levels is the speed in which they have risen. In the millions of years of known geological history, the Earth has never experienced such a rapid rise. The signature of human influence is unequivocal. There is no doubt that we have caused this change to the atmosphere from burning fossil fuels.
