The rejection of climate change science is organized by a countermovement, a collective effort to oppose a threatening social movement, in this case global environmentalism along with climate mitigation efforts. This chapter shows that, from a comparative perspective, the Anglo group of countries are quite alone in organizing the Climate Change Countermovement (CCCM), even though climate denial manifests in an unorganized way more broadly. This chapter offers the theoretical possibility that this Anglo climate denial emerges as a defense of imperial privilege threatened by the social change required to address a warming world. The theory is then supported by selections from authors of books who reject climate change and that evidence a fear of loss—of US power, of possessive individualism, and of Western progress.
