A sleeping giant has awakened. Instead of looking at the U.S. withdrawal from the Paris Agreement as a negative, look at this as the passing of the baton to American businesses and citizens to do what Americans do best—innovate and lead!
There is a short analogy that has been used to explain the human response to climate change (whether in the form of denial, inaction, or delay, or simply nonchalance): that if you throw a frog into a pot of boiling water, he will hop right out, but if you put the frog in a pot of cold water and then turn on the burner, he will remain calmly in the pot until he is fully cooked.
The analogy does provide some insight into our lackadaisical response to a changing climate. From a human perspective, climate change is indeed a slow-moving phenomenon, but geologically-speaking, it is incredibly rapid. As a set of events and changes unleashed primarily by our discovery of fossil fuels some 300 years ago (and dramatically increased rates of extraction and combustion mostly in the last hundred), a cognitive sense of changing climate is distributed across only a dozen generations – either too slow to notice, or too ambiguous to come to conclusions about causality.
