Professor Hidefumi Kurahashi of the Graduate School of Social Sciences, Chiba University and others have released the "Climate Change Meteorological Data Providing System," which allows you to refer to meteorological data from 760 locations nationwide in a graph, going back to the past 40 years.The contents show the climate change situation of each local government at a glance, and can be used for formulating global warming countermeasures for local governments.
According to Chiba University, the data released by the system are the maximum values of average temperature, annual precipitation, and hourly precipitation observed by the Japan Meteorological Agency from 1981 to 2020.When you enter the code of the city, town, or village you want to check, the candidates for the observatory to be referred to are displayed, and if you select the observatory and enter the code, you can obtain the data of that observatory.This data is graphed and can be used as a graph for municipalities to refer to in their regional climate change adaptation plans.
The 2021 Glasgow Climate Agreement has made it a universal goal not to raise the global average temperature rise in 2100 to more than 1.5 degrees Celsius compared to before the Industrial Revolution.However, the average temperature of the earth has risen by about 1 degree, and not only the reduction of greenhouse gas emissions but also the adaptation to the rise in temperature has emerged as an important issue for the region.
In the mean values of 709 points excluding the stations with missing data, the average temperature increased by 40 degrees in 1.26 years, the annual precipitation increased by 184.2 mm, and the maximum hourly precipitation increased by 1 mm.There are only 9.9 observatories where the temperature is declining, and only 4 are where the annual precipitation is declining, and the tendency of temperature rise and precipitation is remarkable.
