Summary: With rapid warming since the mid-20th century, China has experienced remarkable changes in extreme temperatures. The study shows that warm extreme temperatures have become more intense and frequent compared to cold extremes, with anthropogenic factors identified as the main driver of these changes, especially for warm extremes.

Summary: The precipitation in southern China during January-February 2022 was the second highest since 1961. Anthropogenic influence, according to the HadGEM3 (CMIP6) model, reduced the likelihood of extreme events like the one in 2022 by approximately 50% (55%).

Summary: We investigate the contribution of anthropogenic forcing to extreme temperature and precipitation events in Central Asia. Our analysis shows a higher risk of extreme heat events and precipitation events in the region, particularly in Kyrgyzstan and Tajikistan.

Summary: Greenhouse gas forcing has doubled the likelihood of events like the wettest September in northern China in 2021, while anthropogenic aerosols have played a minor role in suppressing these events.

Summary: The summer of 2020 witnessed an extreme dry-wet contrast over South China, which occurred once in every 183 years. Anthropogenic influences have increased the risk of such extremes by at least 3 times.

Summary: Climate models predict an intensification of extreme precipitation under climate change, but this effect is difficult to detect in the observational record. Using machine learning methods, a physically interpretable anthropogenic impact on extreme precipitation is found in global observational data sets.

Summary: In recent decades, the non-stationarity of extreme climate events has been reported worldwide, and traditional stationary analysis methods are no longer sufficient to properly estimate the occurrence probability of climate extremes. This study adopts stationary and non-stationary models to estimate the occurrence probability of extreme precipitation over China and includes low-frequency oscillation indices as time-varying covariates. The results show significant increasing trends in the occurrence probability of extreme precipitation in northwestern and southeastern China, while opposite trends are observed in other regions. The use of low-frequency oscillation indices as covariates improves the fitness of extreme precipitation series for both models.

Summary: Global warming has had a clear impact on the occurrence of extreme events. Observations show a decrease in cold extreme temperatures and an increase in hot extreme temperatures over the past decades. Analysis of climate model simulations reveals that anthropogenic forcings are the main drivers of these changes.

Summary: In the summer of 2020, Eastern China experienced excessive Meiyu rainfall, leading to frequent extreme rainfall events. Anthropogenic influences, such as greenhouse gas emissions and aerosols, have been found to significantly impact the probability of extreme rainfall events, with greenhouse gases increasing the likelihood and aerosols decreasing it. Further research suggests that with continued emission of GHGs and reduction of aerosols, similar heavy rainfall events are projected to occur more frequently, emphasizing the importance of implementing effective mitigation measures.

Summary: This study investigates the relative contribution of different external forcings to observed warming in China over 1901-2018. Climate models were able to reproduce the long-term warming trend, but slightly underestimated the temperature increase. Observed data shows that the annual warming of 1.54 degrees C was mostly due to human influence.

Summary: Surface ozone pollution has emerged as the major concern in China due to the improvement in particulate matters in the atmosphere. Unfavorable meteorology conditions, such as prolonged extremely cold or hot weather, have a significant impact on ozone formation. However, the mechanisms behind ozone changes in extreme temperatures remain poorly understood.

Summary: The impact of rapid urbanization on the spatiotemporal pattern of short-term extreme precipitation in China varies across different regions, with urban areas experiencing more extreme precipitation than suburbs. Urbanization also increases extreme precipitation during peak times in diurnal cycles. These patterns should be considered when assessing the risk of increased waterlogging and flash flooding in urban areas.

Summary: The influence of anthropogenic activity and other external factors on extreme temperature changes in mid-high latitudes of Asia was studied. The results show that anthropogenic activity has detectable effects on warm and cold extremes, with greenhouse gas forcing playing a key role. Increased anthropogenic activity has intensified warm extremes in the region during the past few decades.

Summary: This study aimed to explore the interactions between extreme temperatures and PM2.5 pollution on mortalities. Using data from Jiangsu Province, China collected between 2015 and 2019, the study found that hot extremes were associated with higher relative risks of total and cause-specific mortalities compared to cold extremes. Significant interactions between hot extremes and PM2.5 pollution were also identified, particularly with regards to ischaemic heart disease. This study provides a comprehensive understanding of the interactions between extreme temperatures and PM2.5 pollution on mortalities.

Summary: Studying the frequency and magnitude of climate extremes is crucial in understanding the impact of natural and human factors as the world warms. Using advanced time series methods, we analyze the spatial and temporal role of these factors and find that extreme temperature and rainfall events have significantly increased in risk globally. Anthropogenic forcing is the primary driver of this increase, amplifying the effects of natural forcing. We also identify risk hotspots based on high exposure and vulnerability, such as regions with high GDP and population. In 2018, anthropogenic forcings were responsible for increased risk to extreme temperature/precipitation affecting a significant proportion of the global population and GDP compared to the baseline period 1961-1990.
