Did the planet and the inhabitants of said planet survive the other periods of warming? Other periods of warming have been far more extreme than this one.
Can I deny that humans hurt the climate? Can you state with certainty that they do hurt it? I would agree that humans have polluted the environment, but I am not even one small bit convinced that we, short of nuclear armageddon, can change the climate.
I look at the current warming on Mars, where the polar ice caps have all but disappeared, and wonder how it is that all of our human caused warming has spread that far.
