Global warming, which is still occurring, causes various problems in human society and the natural environment.On the other hand, due to rapid technological development, urbanization and globalization, socio-economic activities are closely linked in various ways, and the natural environment also exerts various effects on each other.These complex interdependencies of human society and the natural environment create an "chain of effects" in which one problem created by climate change causes another.
Previous studies have summarized the impacts of climate change by sector or region, but none have systematically summarized the chain of impacts across different disciplines worldwide. ..
Under these circumstances, research project teams such as the National Institute for Environmental Studies, the University of Tokyo, and Tokyo Institute of Technology have succeeded in visualizing the impact chain of climate change.The trial of this project is to comprehensively investigate all the possible impacts of climate change in the world and the chain relationship between the impacts using existing literature, and to make the obtained data visually easy to understand. It is expressed by.In order to cover all the fields where impact occurs, seven fields of water resources, food, energy, industry and infrastructure, natural ecosystems, disasters and security, and health are selected, and project members who are experts in each field have 7 A literature search was conducted on studies that evaluated what could happen during the century.Then, the effects of climate change are summarized in 21 items, the climate change factors that cause these effects are summarized in 87 items, and the 17 causal relationships between these items are summarized as a chain of effects.
Analysis of the impact chain diagram reveals a large structure in which climate change affects the natural environment, causing social and economic problems and ultimately human life.This research is thought to contribute to the understanding of the overall picture of global warming by many people, not just researchers.
