Japanese adaptation policy and the analysis and mapping of impacts under Climate Change for Adaptation and Food Security Project

摘要

In Japan, relatively low temperatures continued up until the 1940s, but then started to rise. After experiencing high temperatures in around the 1960s and rather low temperatures until the mid-1980s, the temperature rapidly rose from the late 1980s. Many of the years that marked record-high temperatures in Japan are concentrated in the 1990s and onwards. The frequent occurrence of high-temperature years in Japan can be construed as a combination of global warming caused by an increase in greenhouse gas emissions represented by carbon dioxide and the natural fluctuation repeated with a cycle of a few years or a few decades.
