At Wednesday's hearing, retired Army Major General Robert Scales, who said he had "deep reservations" about the science of climate change, worried that if fossil fuels were curtailed it would reduce the availability of diesel and jet fuel "that might reduce our ability to go to war."
On the prospects of global political and military instability from climate change, Scales said, "such unlikely events would cause enormous suffering and social dislocation. But the history record strongly suggests that such devastating humanitarian disasters rarely if ever result in large-scale wars."
