“…The correlation coefficients between precipitation and temperature for both the two periods (i.e., 1931–1970 and 1971–2010) are shown in Figure S1. Negative precipitation and temperature correlations are shown for each period in most regions (except for the Qinghai‐Tibet Plateau in western China), which is consistent with previous studies (He et al ., 2015; Zhou and Liu, 2018; Aihaiti et al ., 2021). The overall negative precipitation–temperature dependence during summer is closely related to the occurrences of CDHEs.…”

Compared to individual dry or hot events, compound dry and hot events (CDHEs) usually pose more severe economic and societal impacts. A growing body of literature investigates the role of anthropogenic forcing on variations of individual dry and hot events at different spatial scales. However, the attribution of CDHEs in China using model simulations from the Coupled Model Intercomparison Project Phase 6 (CMIP6) has received little attention. This study investigates the anthropogenic influence on CDHEs during summer in China and projects their future occurrences using CMIP6 simulations with data from the Climatic Research Unit (CRU) as observations. The results show that large regions of China experienced a significantly increased frequency of CDHEs during 1971–2010 relative to 1931–1970, which is overall captured by the CMIP6 simulations. Anthropogenic forcing is shown to contribute to the high likelihood of CDHEs in recent decades over most parts of China, with remarkable contributions in southwestern regions. Under future socioeconomic development scenarios, these CDHEs are projected to become more frequent in 2021–2100, which will increase by approximately 51.56–55.00% on average compared to that in 1931–2010. This study could aid the development of mitigation strategies of CDHEs across China under global warming.

“…However, it does not mean that future precipitation events do not need too much attention. The probability of extreme precipitation events is increasing under climate change (Aihaiti et al., 2021), resulting in increased crop production damages (Li, Zhao, et al., 2019; Rosenzweig et al., 2002). Generally in cold regions, temperature plays a more relevant role than precipitation in crop production, while crop reduction effects caused by excessive precipitation events are more significant than that in warm regions due to the possibility of waterlogging (Li, Guan, et al., 2019; Shaw & Meyer, 2015).…”

Securing food production is one of the important measures to ensure food security, and has become a critical issue worldwide with the growth of population and increasing food demand, while global crop production could be less stable and more uncertain under future climate change (Agnolucci et al, 2020;Iizumi et al, 2017), mainly due to changes in temperature and precipitation (Aihaiti et al, 2021;Stevanović et al, 2016). Since the Green Revolution in the 1960s, the increase in crop yield was mainly achieved by intensive land management with increasing fertilizer and irrigation water inputs to meet the growing food demand (Tilman et al, 2001).

Adaptation Strategy Can Ensure Seed and Food Production With Improving Water and Nitrogen Use Efficiency Under Climate Change

et al. 2023

Adaptation strategies can reduce the negative impacts of climate change on food security. As an important part of food security, more attention should be paid to seed security, as it determines the crop planting area and ultimately affects food production, especially in major seed production locations, such as the Hexi Corridor in China. This region is an important production base of grain (including field maize and wheat) and maize seed, but the shortage of water resources and low use efficiency of water and nitrogen (N) seriously constrain the sustainable development of agriculture. Formulating an adaptation strategy to balance the seed and food production and resource use efficiency is an important way to maintain regional as well as national food production. We established an optimization‐simulation framework, which consists of a novel crop production function and a grid‐based crop model, APSIM. This framework was used to optimize agricultural management and evaluate its performance considering the spatio‐temporal variability of climate and soil properties, actual crop water consumption and N uptake during each growth stage, and interactive sensitivity coefficients of water and N at different growth stages under climate change. We show that the proposed adaptation strategy could save 0.31 km³ of irrigation water and 22 thousand tonnes of N fertilizer, and increase seed and food production by 33 thousand tonnes, compared with traditional practices. Significant increases in irrigation water productivity and N use efficiency can be expected by using the adaptation supporting the sustainable development of agriculture.

“…Since the start of the 20th century, the sea level has risen at a rate of 1.5-2 mm per year 1 . In the past 100 years, the global average temperature has increased by 0.74 o C, making it about 1.1 o C higher than in the pre-industrial period 2 . Global warming is mainly caused by the massive emissions of anthropogenic greenhouse gases such as CO 2 , CH 4 , and N 2 O, of which the contribution rate of CO 2 is as high as 76% 3 .…”

The effects of different surface modifiers on the CO2 adsorption capacity of coal-based activated carbons were studied, and the diffusion behavior, adsorption kinetics and thermodynamic parameters of CO2 in activated carbons were analyzed. The results show that compared with ethylene glycol, 1,2-propylenediamine and zinc chloride, potassium hydroxide and sodium hydroxide can greatly improve CO2 adsorption capacity. The adsorption rate is faster, and the adsorption capacity is larger, with the maximum CO2 adsorption capacity being 33.54 mL/g. Fick’s law can well describe the diffusion behavior of CO2 in activated carbon. The addition of a surface modifier can increase the diffusion coefficient. The diffusion of CO2 in activated carbon falls into the category of crystal diffusion. The adsorption kinetics of CO2 before and after surface modification follow the Bangham equation. During the adsorption process, δ H < 0, δ G < 0, δ S < 0. Surface modification can reduce adsorption heat and promote adsorption, and the adsorption process is dominated by physisorption.
