Signatories of the United Nations Framework Convention on Climate Change (UNFCCC) have committed themselves to addressing the “specific needs and special circumstances of developing country parties, especially those that are particularly vulnerable to the adverse effects of climate change”.1 The Intergovernmental Panel on Climate Change (IPCC) has since concluded with high confidence that “developing countries will be more vulnerable to climate change than developed countries”.2 In their most recent report, however, the IPCC notes that “current knowledge of adaptation and adaptive capacity is insufficient for reliable prediction of adaptations” 3 because “the capacity to adapt varies considerably among regions, countries and socioeconomic groups and will vary over time”.4 Here, we respond to the apparent contradiction in these two statements by exploring how variation in adaptive capacity and climate impacts combine to influence the global distribution of vulnerability. We find that all countries will be vulnerable to climate change, even if their adaptive capacities are enhanced. Developing nations are most vulnerable to modest climate change. Reducing greenhouse-gas emissions would diminish their vulnerabilities significantly. Developed countries would benefit most from mitigation for moderate climate change. Extreme climate change overwhelms the abilities of all countries to adapt. These findings should inform both ongoing negotiations for the next commitment period of the Kyoto Protocol and emerging plans for implementing UNFCCC-sponsored adaptation funds.
