Figure 2. Vulnerability to climate change, mean GHG emissions, and mean GDP.

(a) Number of countries in each climate change vulnerability category, derived from DARA vulnerability data¹⁸, for 2010 (blue bars) and 2030 (green bars). (b) Mean GHG emissions for 2010, derived from CAIT GHG emissions data¹⁷, shown in CO₂ equivalent units and climate vulnerability categories for 2010 (blue bars, with standard error) and 2030 (green bars, with standard error). (c) GDP shown in current US$ (in billions), derived from the World Bank GDP 2010 data²⁸, and 2010 GHG emissions. (d) Mean GDP for 2010 shown in current US$ (in billions) and climate change vulnerability for 2010 (blue bars, with standard error) and 2030 (green bars, with standard error).
