 note = {Global Warming is a major concern for all the people in the world. To stop the increase of the temperature, it is necessary to reduce carbon dioxide emissions. We Japanese are trying hard to reduce carbon dioxide emissions but density of carbon dioxide is still increasing.
 To clarify the change of temperature in Japan, temperature measured at 43 meteorological observation stations out of 81, which have recorded highest temperature after 1990, were analyzed. Monthly averaged minimum, maximum and average temperature since 1958 were approximated by least square method and gradient of regression line were obtained. 
 It is found that increase of minimum temperature in autumn and spring was significant compared to other seasons., 18, KJ00005305399, 論文, Article},
