When it shows on a global scale how much a hot day of 35 degrees or more by global warming will increase



It is pointed out that human beings are seriously damaged by various factors such as climate change, sea level rise, food shortages, heat waves, etc., as the pace of temperature rise due to global warming is accelerating. It is often dangerous worldwide by showing how frequently the day over 95 ° C (35 ° C) of the boundary line is said to be seriously damaged in one year I understand.

If the temperature rises above 95 degrees Celsius degrees (35 degrees Celsius), the size of the crops decreases and the harvest volume decreases, so that the demand for electricity can catch up with the amount of power generation by increasing the use of air conditioners, It is known that there is.

The graph on the left shows the changes in California, USA of electricity usage. Based on the electricity usage on the day of Mr. Ka 65 degrees (18.3 degrees C), you can see that the use of air conditioner increases as the temperature rises and the amount of electricity consumption also increases sharply. The graph on the right shows changes in the yield of temperature and corn. It can be seen that the crop yield decreases sharply as the temperature rises with Ka 32 degrees (0 degrees C).


Based on the data of Climate Impact Lab, if you create a color map according to the frequency that the temperature is over 35 degrees a year and create it by the period from 1986 to 2099 it becomes as follows.


It is clearly understood that the area where the temperature above 35 degrees Celsius exceeds 100 days will continue to expand in the future, especially in the equator. It should be noted that the map data above is a global framework for climate changeParis AgreementAccording to the criteria stipulated by the law, each country complies with emission limits of greenhouse gases. Given that the framework of the Paris Agreement is still maintained, such as the fact that the United States under the trump regime has declared a departure from the Paris Agreement, is still uncertain as to whether the future is uncertain or not "an optimistic scenario" It is not case study.

In this data, in the US / Washington state, between 1986 and 2005, the average number of days averaged over 35 degrees was 7, but it is thought that in the year 2099 will be 29 on average on average I will.

On the other hand, map data showing what happens when each country does not take measures against global warming is as follows.


To compare with the case of compliance with the Paris Agreement, it is estimated that the annual average number of days over 35 degrees in Washington State will be severely warmed up to 74 days, and indeed even more than 1 / 5th of a year.

Professor Solomon Shangshan of the University of California, Berkeley said, "When talking about temperature rise, there is a tendency to think that many people can" enjoy the day when they can swim. "However, although not so much attention, With the rise the days of hot weather will increase, so bad things that can not be thought will happen in every direction and you can distort your life. " In recent years, scientists are studying how the pace of crime and conflict will change as the temperature rises.
