Partition of causes of climate change (above) and responses to climate change (below) along the dimensions of “environmental practice” and “scientific plausibility.” For the former dimension, climate change causes are classified as reflecting either “poor” or “good or neutral” environmental practice, while responses are classified as reflecting either “good” or “poor or neutral” environmental practice.

† “Banning CFCs” was a plausible abatement strategy in 1992, but in 2009 is implausible (since it has already been done). “Converting to electric cars” was implausible in 1992 but in 2009 is clearly plausible. The original (1992) coding is used in Equations 2 and 4; the revised (2009) coding is used in Equation 5.
