 267 organizations from Inner Mongolia, Gansu, Shandong, Beijing, Tianjin, Henan, Anhui, Shanghai and other regions, as well as public interest partners who concerned about climate change and natural disaster relief, and some of the staff of the foundation all participated in this event.

In this issue, Professor Xu Yinlong from the Institute of Agricultural Environment and Sustainable Development, Chinese Academy of Agricultural Sciences shared a popular science report with the theme of "Where does extreme weather come from?" from three levels of "scientific facts about climate change, basic concepts of adaptation to climate change, and typical case analysis on how to deal with climate risk".  The relationship between global warming and the intensification of extreme weather events is analyzed in a simple and profound way.  On this basis, the connotation and logical level of adaptation to climate change are analyzed, and the case of Zhengzhou "7•20" rainstorm is used to analyze how to strengthen the prevention and mitigation of adaptation to climate change in cities facing increasing climate risk.

1 Climate disasters are getting worse

 

Over the past century, human activities have led to the increasing concentration of CO2 in the atmosphere, and the global greenhouse effect has become increasingly severe.  According to the IPCC Sixth Assessment Report released in 2021, the global observed temperature has increased by 1.09/120a, and the temporal and spatial mismatch of precipitation distribution has become more and more obvious, which has brought a series of problems such as glacier melting, sea level rise, and ecological environment deterioration, posing great challenges to human survival and sustainable development.  From the point of view of the increasing concentration of greenhouse gases in the atmosphere, the enhanced greenhouse effect produces huge energy accumulation, this paper analyzes why the extreme weather and climate events and the climate disasters caused by them become more and more intense.  In Particular, China is facing a series of new characteristics of climate change: increasing climate volatility, especially in the north, and increasing climate volatility in the northeast, with frequent occurrence of extreme high/low temperatures;  The rain belt moved northward, light rain frequency decreased, heavy precipitation events increased, drought and flood alternated, typhoon intensity increased;  Extreme weather events occur frequently and concurrently, with drought and flood turning sharply and rainy days rarely seen in southern China.

 

2  How to deal with climate risk

 

In the face of the increasing threat of climate change, mitigation and adaptation are two basic approaches to deal with climate change.  Mitigation refers to the reduction of greenhouse gas emissions by human intervention. It is a long-term and arduous global task to solve the greenhouse effect which caused by greenhouse gas emissions from the root. The adaptation of natural and human systems to the actual or projected impacts of climate change, is a reality that every country, region, community and individual will face for a long time.  The principle of adaptation is to seek advantages and avoid disadvantages, and the core is to adjust human behavior.  Professor Xu analyzed four basic levels of adaptation: the average trend of adaptation to climate change, adaptation to increasing extreme weather and climate events, ecological consequences of adaptation to climate change, and economic and social consequences of adaptation to climate change.  Strengthen climate resilience through scientific and rational actions to adapt to climate change, and fundamentally improve urban disaster prevention and mitigation capabilities.

 

3 Typical Case Analysis

 

Extreme weather events brought about by climate change are becoming more and more frequent, and the perception of the public is becoming more and more significant. Taking the rainstorm in Henan Province in July 2021 as an example, the Disaster investigation team of The State Council determined that the disaster was a "natural disaster" in general, and a "man-made disaster" in particular. Through a detailed analysis of the response of the existing emergency response system before, during and after a disaster, we can see the problems existing in it. Current cognitive deficiencies, the risks of climate change and mitigation of climate change brings new situation new task has not been enough attention and vigilance, in traditional way of emergency response to climate change under the influence of sudden strong, the strength is huge, and wide spatial distribution of the new type of extreme events will eventually lead to deal with your head, and cause great loss of people's life and property.  To reduce climate risk loss, we need to draw a lesson from these disasters have occurred, from the Angle of climate change, improve the cognition to the climate risk, strengthening the concept of adaptation to climate change, to adapt to climate change in the climate risk response plan, conduct effective adaptation to climate change action, will adapt to integrate all aspects of everyday activities (i.e., mainstream).

Through live broadcast promotion, online interaction, exchange and Q&A, this event deeply interpreted extreme weather and enhanced scientific cognition.
