C. scientists cannot agree on a general model of how the greenhouse effect went from being a positive to a negative and a life-threatening force.
D. global warming actually benefits 90 percent of the world's population, so it is difficult to mobilize the will to address the anthropogenic causes of climate change.
E. it is difficult to distinguish between climate change and global warming.
