The entrée of climate change politics to the center stage of international relations has been accompanied by broad range of strategic linkages, which have produced various institutional interactions. This special issue takes stock of the wide range of ways that international regimes are strategically linked to climate change politics. We do this with a view to better understand both how climate change is shaping the global environmental political landscape, and is being shaped itself through strategic linkages to regimes both within (i.e. forests, biodiversity, fisheries, and desertification) and beyond (i.e. security and human rights) the environmental realm. The contributions that make up this special issue explore when, how, and by whom regime linkages should be pursued, how linkage politics are affecting regime development and function, and in turn how these changes are shaping the evolution of global environmental politics and problem solving writ large.
