Bringing the issue back in: Comparing the marketability of the ozone hole and global warming

This study takes advantage of fortuitous similarities to compare the role o f claimsmaking activities and marketability in affecting the outcomes of wa rnings about ozone depletion and global warming. While global warming has p roduced more claimsmaking in different public arenas, it consistently obtai ns lesser outcomes. in lieu of differences in claimsmaking, political oppor tunities, or rhetorical strategies, it is suggested that a clustering of fa ctors fostered a "hot crisis" around ozone depletion but not global warming . The analysis suggests that it is the extent to which the trajectory of a problem meshes with the prevailing institutional selection principles that determines how salable it is.
