The climate is getting warmer and extreme weather is frequent. Look at the answer

The warm winters in recent years have given people an illusion that climate warming means that the temperature is rising and the weather is getting warmer and warmer. In this regard, climate experts explained that climate warming is a general trend, but it does not mean that the cold is no longer. Climate warming will lead to frequent extreme weather events, such as snowstorm, cold current, rainstorm, heat wave and drought.

(2) Severe cold is the manifestation of abnormal weather under the background of global warming. Kumar Koli, an expert of the World Meteorological Organization, said in Geneva recently that climate warming will not only bring unusually warm winters, but also lead to extreme weather events such as severe cold, high temperature in summer, the rise of every plane, the disappearance of island countries and the melting of polar glaciers.

Due to global warming, natural disasters have more than tripled in the past 20 years. Curley said that in the early 1980s, there were 120 natural disasters every year in the world, but now it has increased to 500, and the number of people affected has increased by 68%. From 1985 to 1994, the global average annual population affected by disasters is1740,000; From 1995 to 2006, the average number of people affected by disasters increased to 254 million per year.

④ Extreme weather often occurs all over the world. Zheng Guoguang, director of China Meteorological Bureau, pointed out that abnormal atmospheric circulation and La Nina event are the main causes of meteorological disasters in southern China.

⑤ Under the background of global warming, extreme weather and climate events occur frequently around the world; On June 29th to 3rd1year1October 29th, 65438+, a rare snowstorm hit the countries in the eastern Mediterranean and the Middle East, which are famous for their warm climate. The thickness of snow on the border between Syria and Lebanon exceeds 1 m. 654381October 8, Iran suffered the biggest snowfall in more than a decade. 65438+1In mid-October, continuous snowfall in Afghanistan caused a snowstorm. In some areas, the snow is as deep as 2 meters. The snowstorm also hit the midwest of the United States and eastern Canada, with some airports closed and road traffic paralyzed.

6. Climate warming does not mean that the temperature is rising. Ai Wanxiu, a senior engineer at the National Climate Center, said that climate warming does not mean that the temperature is rising, and winter is getting warmer and warmer. "Warm winter" is the average concept of temperature in the whole winter, and "warm winter" may also explain weather fluctuations such as sharp cooling. Climate change is gradual, but the impact of extreme weather and climate events is sudden.

Today, the climate is still normal and warm. Zhang Chengyi, chief scientist of the National Climate Center, said: "Although there is a lot of rain and snow this winter, from the general trend, this year is still a warm winter. In general, I think blizzard is related to climate change. " Under the influence of climate change, the water vapor content in the atmosphere has increased. When the water vapor content increases, it will definitely decrease at some point. This process must be related to the weather. Climate warming is long-term. Even if the temperature drops this winter, it may still get warmer. Judging from the current forecast, this year is still a warmer year.

18. The order of this article is. (2 points)

19. talk about the consequences of global warming according to the actual life and the extracurricular knowledge learned. (3 points)

Reference answer

14. Climate warming will lead to frequent extreme weather events such as snowstorm, cold current, rainstorm, heat wave and drought.

15. Methods: Enumerate figures and compare them. Function: More scientifically and accurately show that with global warming, the number of natural disasters is increasing faster and faster. (just agree)

16. Cannot delete. "Main" shows that the causes of meteorological disasters in southern China are different, not unique, and reflects the accuracy of the eliminated interpretation language. (just agree)

17. It shows that under the background of global warming, extreme weather events occur frequently around the world and the disasters caused by them. (just agree)

65438+

19. For example, allergic symptoms are aggravated, animals migrate to high places, tidal water leaks, frozen soil melts, mountain rebounds, forest fires, and satellites turn faster and faster.
