In a classroom in Wilson Library, Robert Cox pauses to
update his class about the sudden disintegration of a massive Antarctic ice
shelf.
Raising his eyebrows, he gestures animatedly in front of
satellite images depicting a slab of ice the size of Connecticut crumbling into
the ocean.
With passion in his voice, he adopts a preacher-
like rhythm that suggests that some of his words are italicized: “The physics
of it are so uncertain and unstudied that we cannot model how quickly this will
break down.” He is referring to scientists’ projections about how global
warming will affect the rest of the ice.
Cox has good reason to be passionate about the collapse of
Antarctic ice. In addition to teaching
a course about global warming in the communication studies department, he is
president of the board of directors of the Sierra Club.
