ABSTRACT

The CMIP5 climate change scenarios from 34 GCMs were analyzed to quantitatively assess future changes in temperature, precipitation, and solar radiation against the global region and the Northeast Asia region with a focus on South Korea, North Korea, or Japan. The resulting projection revealed that the Northeast Asia region is subjected to more increase in temperature and precipitation than the global means for both. In particular, temperature and precipitation in North Korea were projected to increase about 5.1°C and 18%, respectively under the RCP 8.5 scenario, as compared to the historical means for 30 years (1971-2000), although a large uncertainty still exists among GCMs. For solar radiation, global mean solar radiation was predicted to decrease with time in all RCP scenarios except for the RCP 2.6 scenario. On the contrary, it was predicted that the amount of solar radiation in the Northeast Asia increases in the future period.
