John Crisp’s article on climate change makes one wonder what the early Pliocenes were doing 3 million years ago to cause the atmospheric carbon dioxide levels to be as high as they are today, and what behavioral changes they made to cause it to lessen over the next several million years? The earth’s temperatures may be rising lately, but as recently as the 1970s climatologists thought we were heading towards another ice age due to the severe winters. Earth’s temperatures fluctuate over time and it’s the height of arrogance to suggest we, as humans, can control it.
