"It should be understood by anyone professing an interest in climatology that the object of study has been around longer than man and the climate here has varied radically in the last 40 million years. In the Eocene carbon dioxide levels were several times higher than they are currently. The temperature was quite compatible with life from pole to pole. Until we can understand that, or how Earth moved from there to the Miocene, then the Pliocene and then the Holocene, each with its own climate, flora and fauna, we have no good reason to think we understand climate. To make predictions about what follows from here and when, and to audaciously begin the discussion by implicating our humble species in the whole thing is worse than audacious, it’s pathetic."
