Abstract

It has been demonstrated that climate change is an established fact. A good comprehension of climate and extreme weather variation characteristics on a temporal and a spatial scale is important for adaptation and response. In this work, the characteristics of temperature, precipitation, and extreme weather distribution and variation is summarized for a period of 60 years and the seasonal fluctuation of temperature and precipitation is also analyzed. The results illustrate the reduction in daily and annual temperature divergence on both temporal and spatial scales. However, the gaps remain relatively significant. Furthermore, the disparity in daily and annual precipitation are found to be increasing on both temporal and spatial scales. The findings indicate that climate change, to a certain extent, narrowed the temperature gap while widening the precipitation gap on temporal and spatial scales in China.

Highlights

The global average temperature has climbed 0.85 ◦ C since the industrial revolution, which resulted in remarkable warming in certain areas and impacts on flora and fauna, the ecosystem, health, public safety, and so on [1].A number of research studies hold that climate change will cause some health problems [2,3,4].For instance, Phalkey argued that there is significant correlation between climate change and child malnutrition [2]
A similar research study of Asseng showed 1 ◦ C warming could lead to 6% reduction of wheat output, which is equivalent to one-quarter of wheat trade volume worldwide if no adaptive measures are taken [7]
For temperature change and extreme temperature: On the whole, a warming tendency is observed in all seasons nationwide

Summary

Introduction

The global average temperature has climbed 0.85 ◦ C since the industrial revolution, which resulted in remarkable warming in certain areas and impacts on flora and fauna, the ecosystem, health, public safety, and so on [1].A number of research studies hold that climate change will cause some health problems [2,3,4].For instance, Phalkey argued that there is significant correlation between climate change and child malnutrition [2]. The global average temperature has climbed 0.85 ◦ C since the industrial revolution, which resulted in remarkable warming in certain areas and impacts on flora and fauna, the ecosystem, health, public safety, and so on [1]. A number of research studies hold that climate change will cause some health problems [2,3,4]. Another study showed that 1 ◦ C warming in the summertime could induce 1%. Regarding the ecosystem and agriculture, Liu found that a 1 ◦ C temperature rise could reduce wheat output by 5.7% (95% confidence interval ranges from 4.0% to 6.9%) [6]. A similar research study of Asseng showed 1 ◦ C warming could lead to 6% reduction of wheat output, which is equivalent to one-quarter of wheat trade volume worldwide if no adaptive measures are taken [7]
