Evidence?
What an extraordinary claim! The ocean is deep, and slow, atmospheric CO2 is < 200 ppm, an 18th of what it was in the Ordivician period. Has the ocean been saturated before? What evidence is there for these claims? What predictions are made by the theory of globally threatening, man-made climate change, and do they turn out to be true? Did polar bears and penguins survive the last warming? Did anything thrive in the last ice age?
