This article investigates the messages about climate change that ten nature protection organizations in Germany, the Netherlands, and the United States communicate to their members and the public through their Internet sites, member magazines, and annual reports. Based on analysis of this content, we conclude that all the organizations address climate change, but to varying extents and in differing ways. All of the organizations note that climate change is a major problem, has a significant impact on nature, and should be addressed mainly via mitigation. With the partial exception of the Dutch groups, all also inform their members about domestic climate change politics. Other themes, including international dimensions of climate change, adaptation to climate change, consumer behavior, collaboration with and criticism of business, and efforts to pressure business or government received less emphasis overall. How much emphasis the organizations gave these themes was conditioned by their traditions, constituencies, national context, and international affiliations.
