1. What is extreme weather? Extreme weather and climate events are rare meteorological events in a certain area in a certain period of time, and their occurrence probability is usually less than 5% or 10%.

Extreme weather and climate events can generally be divided into extreme high temperature, extreme low temperature, extreme drought, extreme precipitation, etc., which are generally characterized by low probability of occurrence and great social impact.

With global warming, the frequency of extreme weather and climate events has changed, showing an increasing trend.

In 2007, Britain suffered a once-in-200-year rainstorm;

In 20 10, there was a century-old flood in Pakistan and a century-old drought in Russia.

20 1 1 year, tornadoes in the United States caused hundreds of deaths;

In 20 17, the hurricane season was extremely active and hit the north Atlantic one after another.

20 18, hurricane? Florence? Attacking North and South Carolina in the United States, causing floods;

According to United Nations statistics, the population affected by the storm reached 654.38+02.8 million, and 654.38+0593 people died. In terms of economic losses, hurricanes? Florence? And then what? Michael. Causing about $30 billion in losses to the United States, typhoon? Swallowing it caused a loss of about 654.38+0.25 billion dollars to the Philippines.

In 20 19, the temperature in the midwest of the United States was colder than that in the North Pole, while on the other hand, Australia suffered an extreme heat wave, as if it were in a sea of fire. In addition, in other parts of the world, many parts of Europe suffered from heavy snow, while Brazil, Chile and Indonesia suffered from floods.

Extreme cold caused direct deaths, schools in many areas were closed, and infrastructure such as electricity and natural gas was overwhelmed.

High temperature caused local asphalt melting, infrastructure failure, large-scale sudden death of animals and fish (one third of them died within two days) and wildfire.

Second, the impact of extreme weather on us? Economic risk

Climate change is not only an environmental problem, but also a major risk facing the global economy.

Extreme weather will have a great impact on many industries. Take the extreme cold in the United States as an example. In the United States, 2300 flights were cancelled, 1 1800 flights were delayed due to weather, trains with frozen tracks could not operate normally, UPS and several transportation companies suspended services, and large-scale electricity consumption caused the power infrastructure to be overwhelmed. The futures prices of natural gas and crops in the United States fluctuated, and some commercial and government institutions were forced to temporarily close down.

The United Nations recently released the report "20 19 World Economic Situation and Prospects", which listed a series of major issues facing the global economy. The report pointed out that with more and more extreme weather events around the world, climate risks are increasing. From 1998 to 20 17, the losses caused by climate-related disasters reached $2.245 billion, an increase of 15 1% compared with the period from 1978 to 1997. 2. Impact on human beings

Extreme climate change will increase the incidence of various diseases and human mortality. Or directly lead to human death. The ongoing COVID-19 is a new virus discovered under the current climate warming, which leads to global economic chaos and makes it inconvenient for people to travel.
