WMO announces record high in 2015 at 400ppm of global CO2 concentration risk level

The World Meteorological Organization (WMO) announced on the 24th (GMT) that carbon dioxide (CO), which causes global warming,2) In 2015, the world average concentration reached 400ppm, which is considered to be the “dangerous level concentration”, and it was announced that it reached a record high. Observations around the world have shown that it is certain that it will exceed 400 ppm in 2016, but it has reached the dangerous level in 2015.According to WMO, CO2Similarly, the 15-year global average concentrations of the greenhouse gases methane and nitrous oxide also reached record highs.The 22nd Conference of the Parties to the United Nations Framework Convention on Climate Change (COP22) will begin in Morocco on November 7 for the first time with the new Paris Agreement on global warming...

Estimate the cost required to prevent heat stroke due to global warming

As global warming progresses, people around the world will work in a hotter environment. Longer breaks are needed to prevent heat stroke, which reduces productivity. A research group at the National Institute for Environmental Studies and the University of Tsukuba said that if global warming progresses without taking measures to reduce carbon dioxide, the productivity lost to prevent heat stroke will be lost to prevent heat stroke in the world’s gross domestic product (2100). It has been announced that it will reach 4% of GDP). The amount of loss is comparable to the cost required for aggressive measures to curb global warming.This research is characterized by realistic calculations that take into account how much air conditioners will become widespread according to the economic developmen...

Global grain yield growth slows due to global warming Estimates by NARO

Among the major grains in the world, corn and soybean cannot meet food demand due to slowing of yield growth even if the temperature rise by the end of this century is less than 1.8 ℃. It was found by estimation by research groups such as. A research result suggesting the food crisis caused by global warming, the paper was recently published in the English scientific journal “Scientific Reports”.The Paris Agreement, an international framework for the prevention of global warming, stipulates that the rise in global average temperature should be kept below 2 ° C, preferably below 1.5 ° C, by the end of this century. A research group consisting of Toshinao Iizumi, a researcher at the Agricultural Environmental Change Research Center of the Agricultural Research Organization, members of the In...

Strong wind area of ​​typhoon spreads to the outside due to global warming

Typhoons, which bring disasters to Japan almost every year, are a bit of a problem even in research to elucidate the mechanism with computers.First, the air pressure in the center is very low. Typhoon No. 18, which traversed the Japanese archipelago from September 13th to 18th, had a central pressure of about 930 hectopascals. Since the atmospheric pressure on the ground is usually about 1000 hectopascals, such a low central pressure means that the atmospheric pressure is changing rapidly in a narrow area. Therefore, in order to calculate the structure of a typhoon with a computer, it is necessary to reproduce the area finely and with high accuracy. Otherwise, we cannot keep up with the sudden changes. However, this would increase the amount of calculation. Research does not go as planned...
