Calvin and Hobbes by Bill Watterson for July 23, 1987
Calvin: Hey Mom, what's this I hear about the greenhouse effect? They say the pollutants we dump in the air are trapping in the sun's heat and it's going to melt the polar ice caps! Sure, you'll be gone when when it happens, but I won't! Nice planet you're leaving me! Mom: This from the kid who wants to be charffered any place more than a block away. Calvin; Hey. Noboldy told me about the ice caps, all right?
