The present invention relates to a climate change big data analysis system that can accurately visualize and provide an extreme climate event desired by a user at a fast speed. To this end, the present invention, a data collection unit for collecting climate change scenario data necessary to respond to data requested by a user; a data pre-processing unit for generating location coordinates corresponding to the climate change scenario data by using the climate change scenario data and map data; a data analysis unit for extracting data corresponding to the request data from the climate change scenario data; It provides a climate change big data analysis system comprising a data visualization unit that displays the data extracted by the data analysis unit to be superimposed on the map data. Therefore, according to the present invention, it is possible to prepare for climate change in advance in many fields such as agriculture, fishery, sports, etc. by enabling general users as well as analysts to easily know the future climate change.
