According to Krakoff, Why Do the Temporal and Spatial Dispersion

Multiple Choice

According to Krakoff, why do the temporal and spatial dispersion of the effects of carbon dioxide make climate change an especially difficult challenge?

A) Because they lead to a situation in which each generation in each country has a self-interested reason to continue emitting carbon dioxide, although those emissions will harm other countries and future generations.
B) Because they force us to make choices about climate change without complete certainty about what the effects of our emissions will be and who will suffer from those emissions.
C) Because they cancel each other out from the perspective of self-interested countries, with the temporal lag giving each country a reason to stop emitting carbon dioxide but the spatial dispersion giving each country a reason to continue emitting.
D) Because they provide us with an excuse to claim that we are not really causing climate change, thereby undermining the motivation to respond to it.
