"Hot Dead" is no longer a joke this summer.

Within 7 days at the end of June, a total of 719 people in British Columbia, Canada may die at unusually high temperatures; earlier May, three young children in Pakistan were killed at high temperatures; India ushered in the highest temperature in 122 years, and nearly a hundred people were in the heat waves. Killing; my country has repeatedly repeatedly died due to heat irritation ...

On July 8th, the World Meteorological Organization (WMO) declared that according to the European Copernicus climate change service agency data, the world has just experienced the third hot June in the record, and a wide range of extreme high -temperature incidents appeared.

How many poles?

The first is earlier than previous years. In Europe, the highest temperature in the central and southern regions of Spain exceeded 40 ° C on June 13, and the heat waves came early, setting a record for Spain since 1981. Next, France, Germany and other high -temperature weather appeared in high temperatures.

The second is the extensive impact. Beginning on June 13, the record high -temperature expanded from the large US plains to the Mississi -Valley and southeast, and the population of more than one -third of the United States was affected. In the past month, high temperature has affected more than 900 million people in my country.

More extreme is the highest temperature of more than 40 ° C or even 50 ° C. For example, the highest temperature in some parts of California in the United States reached 45.5 ° C in June, and the Death Valley exceeded 50 ° C. ℃, southern Pakistan exceeded 49 ° C in May.

High temperature also affects our country. Since June this year (as of July 12), the average high temperature number of high temperatures in my country is 5.3 days, which is the largest in history since 1961. The highest temperature of 71 national meteorological stations in the country broke through the historical extreme value, and there were extreme high temperatures above 44 ° C.

Why is the northern hemisphere so hot?

From the perspective of meteorology, the atmospheric circulation is abnormal (the Western Pacific subtropical high -voltage belt, the Atlantic high -voltage belt, and Iran's high -voltage average staged enhancement and slightly different from the influence scope of previous years. Direct reasons for frequent high -temperature heat waves in many places.

But in fact, it is not "hot" this year. In the past 50 years, global warming has occurred at unprecedented speeds in the past 2000, and the unstable climate system has intensified. The Secretary -General of the United Nations Gutres call it "the red alarm of all mankind."

Global warming is a frequent climate background in the high -temperature heat wave event in the northern hemisphere. The World Meteorological Organization believes that human influence may increase the probability of incidents in composite extreme weather.

The sixth evaluation report issued by the UN Intergovernmental Climate Change Special Committee (IPCC) pointed out that global warming is leading to severe weather events such as rainstorms, floods, droughts, typhoons, high temperature heat waves, cold waves, and sandstorms frequently occur frequently. In the past, the extreme weather and climate incidents of "one encounter of decades" or even "one hundred years" seemed to be becoming more and more common.

Global warming originated from the influence of human activities, and also acts on every humans on the earth. How to alleviate the pace of global warming and "calm" the "calmness" of the "high fever" is a long -term topic that all human beings should think carefully.
