Abstract
In order to discuss the role of the climate change impact research for the agreement on long-term target setting for combating climate change, this paper has summarized important points relevant to the agreement. It follows from these points that one of the important roles of the climate change impact research is integration of discrete knowledge on multi-region and multi-sector impacts. We have developed the climate change impact database which stores the sectoral impact records with common data such as scenario, target year and global mean temperature increase and possesses a function to display plural sectoral impact records in parallel utilizing the common data as an explanatory variable. The database is expected to provide decision-makers the knowledge of impacts effectively aiming at the long-term target setting.
