Abstract: With the vigorous social and economic development, the impact of climate change on people's life-styles in various countries has become an important factor that caused country disability. As a result, more and more vulnerable countries appeared. This papers aims to determine how climate change increases national vulnerability first and then establish measures to mitigate the risks of climate change. We selects twelve indicators to assess national vulnerability and make countries into three classes by cluster analysis: the stable ones, the vulnerable ones and the extremely vulnerable ones. The data of temperature, precipitation and the population proportion of affected population in 2009 were collected. The entropy method was used to determine the weight of each index, then the climate change index of each country was obtained, and the correlation between climate change index and vulnerability index was calculated. Climate change indirectly affects national vulnerabilities by affecting 12 indicators of vulnerability.
