In 2017 it is almost certain that it will be the second heat in observation history and the extreme trend of weather is also revealed

From the meteorological observation data of the entire earth, it is surely ensured that 2017 will be the year with the second highest average temperature in the record so far. Furthermore, the change is not only "rising in temperature", but the characteristic of extreme meteorology is becoming clear.

It's not your imagination: 2017 has been abnormally hot so far | Popular Science

According to the latest data released by the United States Oceanic and Atmospheric Administration (NOAA) on July 17, 2017, it is clear that June in 2017 was the third hotest June in observation history. Moreover, the temperature deviation that occurs when comparing the average temperature in the six months from January 2017 with the average data of the whole 20th century is "Ce plus 0.9 degree", and it is the hottest as shown in the following graph It is also revealed that it was the second hotest half year in 2017, after 2016.

Moreover, the situation of the average temperature around the world is as shown in the figure below. The color is red indicates that the temperature was higher than the average data of the whole 20th century, but you can see that the temperature was above the average on almost the whole earth. In particular, the part shown in red indicates that the average temperature has been reached enough to update the record.

As mentioned above, it is thought that in 2017 it will not exceed the heat of 2016,El · Niñyo phenomenonIt is speculated from the fact that it has not occurred. Seawater temperature rises in the eastern Pacific Ocean in South America / Peru Although it is thought that this phenomenon relates to abnormal weather occurrence in various parts of the world, there is a tendency to influence the average temperature of the earth Since it is seen as there is no occurrence in 2017, it is predicted that the temperature will not rise in 2016.

Nonetheless, it can be said that the average temperature of the earth clearly shows a clear rise in the long run, which is also undeniable fact. The annual average temperature when it is based on 1880 is a graph like the following, you can see the tendency that the earth is generally getting hot and rising to the right.

However, it should be noticed that it is not simply "the earth is getting hot", but it is that the frequency and extent of abnormal weather events are increasing. One such example is damaged by many people, especially due to the heavy rain which became frequent in the northern hemisphere and the flood caused by it. In addition, the "whitening phenomenon" in which corals are dead and whitened due to the rise in seawater temperature has been confirmed in various places, and also in the world-famous "Great Barrier Reef" of Australia, large-scale coral bleaching for the second consecutive year The phenomenon has been confirmed.

Furthermore, the declining ice of the Antarctic and the Arctic is also seen as being involved in climate change. In the Arctic, the scale of ice generation in the winter season is smaller, and in the Antarctic, "Larsen C shelves" with a total weight of 1 trillion tons and about half the size of Kyushu is separated from Antarctica ice shelves It just happened. Along with this, further reduction of shelf ice is predicted, and it seems that it is almost undoubted that the environment of the earth is in the process of rapid change.
