Why do you feel that the climate is getting worse?

Climate change has an important impact on human beings and natural systems. Because ecosystems and human society have adapted to today's and recent past climate, it will be difficult for people to cope with these changes if they adapt too fast. For many developing countries, this may have a very harmful impact on the basic living standards of human beings (housing, food, drinking water and health). For all countries, the increasing frequency of extreme weather and climate events will increase the risk of weather disasters. Climate change has both positive and negative impacts on China's economy and society, some of which are actually irreversible, so we should pay more attention to the negative impacts. According to statistics, from 1950 to 2000, especially after 1990, the economic losses caused by meteorological disasters increased sharply. There are two reasons, on the one hand, the increase of extreme weather events, on the other hand, the increase of China's overall economic volume, so the absolute value of economic losses has obviously increased.

The impact of climate change on agriculture is negative. It is predicted that by 2030, China's three major crops, rice, corn and wheat, will mainly reduce production except winter wheat. Climate change also has a great impact on water resources. Global warming accelerates the water cycle and increases the spatial heterogeneity of precipitation. Climate change also has an impact on major projects, such as the increase in precipitation in the upper reaches of the Yangtze River, which will lead to an increase in the frequency of geological disasters and have a certain impact on the safe operation of the Three Gorges Reservoir. In addition, climate change will also affect the Qinghai-Tibet railway and highway, greatly increasing the investment in railway and highway operation and maintenance.

Like the whole world, China's climate and environment have also undergone tremendous changes. Climate warming goes far beyond the general climate and environmental problems, and has brought a very serious threat to the economic and social development of China, and this threat will continue and intensify. Scientific and technological circles should pay special attention to climate change, actively take adaptation and mitigation measures, and constantly improve the level and level of climate system, ecology and environmental protection. This is an important content of fully implementing Scientific Outlook on Development and building a harmonious socialist society, and it is also the common aspiration of the government, the public and scientists.

The coldest place in winter and the hottest place in summer in China.

The coldest place in China in winter is Mohe Town, Heilongjiang Province. 65438+ 10 The monthly average temperature is -30.6 degrees. The coldest place has an extreme minimum temperature of MINUS 52.3 degrees. This is the lowest temperature in the existing meteorological records in China. The hottest place in China in summer is Turpan in Xinjiang. The average temperature in July is 33 degrees, so it is called "Huozhou". The extreme maximum temperature there once reached 49.6 degrees. This is the highest value in China's existing meteorological records. The average temperatures in Chongqing, Wuhan and Nanjing, known as the "three stoves", were 28.6, 29.0 and 28.2 respectively in July. Compared with Turpan in Huozhou, we have to admit defeat.
