The objective is to assess the economic effects of global warming upon agriculture and global economy under various Shared Socioeconomic Pathways, using EMEDA simulations. The EMEDA has 16 regions and 16 sectors, including five agricultural sectors. Our main outcomes are: all sectors in USA, EU25 and East Asia, and some sectors in Japan, Russia, South Korea, Oceania, and North America will experience economic growth, while the other regions only offset direct agricultural damages by global warming. USA, China and India can positively participate in the COP for the 2℃ target in future for obtaining their own potential large advantages.
