You have likely heard that 97% of scientists agree on human-driven climate change. The overwhelming majority of scientists take no view on the question of whether climate change is man-made, for it is beyond our present knowledge to answer.

Only 0.3% of science papers state humans are the cause of climate change. And when surveyed, only 18% of scientists believed that a large amount – or all – of additional climate change could be averted.

There is no scientific evidence or method that can determine how much of the temperature change since 1900 was caused by humans. We know that temperature has varied greatly over the millennia. We also know that for virtually all of that time, global warming and cooling were driven entirely by natural forces.
