A model of the impact of human activities on climate change
According to the information released by the United Nations Office for Disaster Reduction, from 2000 to 2019, according to the statistics of meteorological disaster losses, a total of 7,348 natural disasters occurred worldwide, with an economic loss of 2.97 trillion US dollars, 1.23 million deaths and 40 affected people. billion people (as shown in Figure 1).
Among natural disasters, 3,254 floods occurred due to heavy rain, accounting for 44%; 2,043 storms caused by extreme weather occurred, accounting for 28%; other aspects such as earthquakes, heat waves (extreme temperatures), avalanches, droughts and forest fires also occurred. There are as many as hundreds of each (as shown in Figures 2 and 3).
The increase of natural disasters is inextricably linked with the development of the world economy and human activities, because the changes in climate caused by human activities are a process of gradual evolution, resulting in six types of climate patterns on the earth unknowingly.
What are the six types of changes in state?
The formation of extreme climates has caused extremely cold, extremely hot, extremely dry and extremely wet weather patterns in different parts of the world, resulting in meteorological disasters all over the world. For example, in July 2018, Japan was affected by strong high pressure, and the hot weather has lasted for more than a week. At least 44 people have died from the heat since July 9. Japan's Kyodo News reported that there were 11 fewer deaths on Saturday alone. The hot conditions continued until Monday (23rd), with Tokyo exceeding 41 degrees for the first time (pictured on the left) .
More and more attention has been paid to climate change, mainly because the impact of human activities on the climate may cause irreversible changes in the climate that are not conducive to human beings. The Energy and Environmental Technology Center of Qinyi University of Science and Technology, in order to cope with the emission of greenhouse gases and waste heat from air conditioners, has developed the "All-outside Natural Energy Conversion System - Oxygen Generator". Emitting hot waste gas into the outdoor environment, it can also wash pollutants and impurities in the air, creating a comfortable and healthy indoor living environment, and at the same time, it can also be friendly to neighbors and the earth, cool the earth by X°C, and contribute to all living beings on the earth. mental strength.
