Extreme weather safety handwritten newspaper is very simple, few words.

The extreme weather safety handwritten report is as follows:

Global climate change is the most serious environmental problem facing all mankind at present. Extreme weather is becoming the new normal. At present, this round of extreme rainfall in Beijing, Tianjin and Hebei has basically ended, but the follow-up disaster relief, flood risk and geological disaster risk continue. In addition to extremely heavy rainfall, this past July, extreme high temperature and super typhoon are also constantly affecting our country.

How to treat the alternation of extreme high temperature and precipitation in July? What kind of reminder does it bring to us? Is the extreme weather in the future really getting more and more normal?

In recent years, with the intensification of global climate change, extreme weather events such as high temperature and heavy rain have occurred frequently. On July 4th, the World Meteorological Organization confirmed that El Ni? o conditions were formed in the tropical Pacific for the first time in seven years, which may lead to soaring global temperatures and destructive weather and climate patterns.

In addition, NASA scientists said that this year is more and more likely to become the hottest year on record, and the situation will not ease next year, and the temperature will be higher than this year.

What is extreme weather? What are the causes of extreme weather?

Wang Guofu, Director and Researcher of Meteorological Disaster Risk Management Office of National Climate Center of China Meteorological Bureau: Extreme weather and climate events include extreme weather events and extreme climate events, which are abnormal events relative to most common events.

That is, when the value of weather or climate variable is higher (or lower) than a certain threshold, the probability of occurrence is generally less than 10% near the upper limit (or lower limit) of the observed value interval of the variable.

The changes of extreme weather and climate events are influenced by the internal variability and external variability of the climate system. Global warming is the main cause of frequent extreme weather and climate events.

From the mechanism, global change, especially the long-term change of marine climate, will affect the monsoon, and the influence of monsoon change on extreme precipitation and temperature will lead to extreme weather and climate events in different degrees.

The report of the United Nations Intergovernmental Panel on Climate Change (IPCC) points out that with global warming, the frequency of extreme weather and climate events has changed, showing an increasing trend.
