Summary: The study analyzed the climate variability and trends in the Kashmir Himalaya region from 1980 to 2017, showing significant increasing trends in temperature across the region with non-significant positive trends in precipitation, with variations observed in different seasons. The changing precipitation patterns could have significant implications on the ecological sustainability and food security of the region.

Summary: The study found that extreme precipitation events in the Indian Himalayas have been increasing over the past 20 years, particularly in February. Specifically, rainy days and altitudes in the Pir-Panjal Range have a significant impact on extreme precipitation.

Summary: Global warming is expected to impact the hydrological cycle in the Mediterranean region, causing changes in precipitation extremes and a gradient between the north and south. Future projections show significant increases in daily precipitation extremes, with the magnitude being underestimated in drier areas for 100-year extreme events.

Summary: This study quantifies the magnitudes of mass-wasting caused by the Asia Summer Monsoon, extreme rainfall, and earthquakes in the Nepal Himalaya, finding that rainfall events and earthquakes may perturb mass-wasting to a much greater extent than expected from monsoon alone.

Summary: This study uses pressure change events (PCEs) as a physical indicator of atmospheric system stability in the tropical areas of Florida to reveal the impact of temperature on precipitation. The results show that the frequency and intensity of PCE are closely related to weather events, with decreasing pressure favoring precipitation, and different types of PCEs affect the probability and depth of precipitation differently, influenced by season and climate.

Summary: The study analyzed global river flow data from 7250 observatories and found that anthropogenic climate change has an impact on river flow. The research showed that some regions are consistently experiencing drying trends, while others are consistently experiencing wetting trends.

Summary: This study assesses long-term changes in extreme daily precipitation observed at 30 locations across Ireland. Results show increases in precipitation intensity, particularly notable in the east and southeast of the island. Contribution of heavy and extreme precipitation events to annual totals is increasing, while no persistent trends in annual totals or consecutive wet or dry days were found.

Summary: This study examines the trends in mean and extreme precipitation in Arizona from 1950 to 2020 using daily precipitation records from 43 weather stations. The results show a great degree of spatial variability and sensitivity to the temporal scale of analysis. While there is no clear consensus on the climatological trends, the ongoing temperature increase associated with climate change has and will continue to impact the hydrologic system of the state.

Summary: With climate change, extreme precipitation events are becoming more frequent and intense. Bhutan, as a developing country, faces immense socio-economic damages and difficult recovery due to these changes. Moreover, changing precipitation patterns have impacts on land productivity and water availability.

Summary: The study investigates and reconstructs the historical hydroclimate variability of the Karnali River catchment in Nepal. The findings reveal past pluvial and low-flow periods, as well as an increasing frequency of extreme low-flow and pluvial events in the recent century. The study also identifies periodicities in the streamflow series that are teleconnected with climate modes like ENSO and PDO. The research provides valuable insights for water resource management and policies amidst current and future climate change.

Summary: Extreme climate events pose significant risks to ecosystems and human society. This study investigated the historical changes and projected trends of extreme climate events in Xinjiang, China. The results showed an increase in warm extreme indices, a decrease in cold extreme indices, an increase in intensity and frequency of extreme precipitation, a decrease in consecutive dry days, and an increase in consecutive wet days. The projections for the twenty-first century align with historical trends, with more pronounced changes in the Tianshan Mountains region. The response of extreme temperature and precipitation indices to global warming is approximately linear.

Summary: This article reviews recent bibliography on time series of extreme weather events and related response indicators, finding that global climate extremes show the most significant changes in yearly heatwave values. Other indicators such as precipitation intensity and extreme frequency are relatively stable. The impact of warming on surface wind speed remains unclear. Analysis of response indicators, including natural disasters, floods, droughts, ecosystem productivity, and crop yields, does not show a clear positive trend of extreme events. Based on observational data, the climate crisis is not yet evident, but it is crucial to develop strategies considering current trends.

Summary: This study evaluates historical and future changes in extreme precipitation events in Alaska. The research finds that while most historical rainfall events have set record highs, the frequency of such events is projected to remain infrequent according to climate models, with the exception of a few locations where heavy precipitation events are expected to increase.

Summary: The article analyzes recent trends in extreme precipitation in the Southwestern Alps and finds that trends vary depending on the season. In autumn, there is a significant increase in extreme precipitation in Southern France, while in other seasons, the Mediterranean region shows mostly negative trends. The changes in extreme precipitation can be partly explained by changes in the dominant influences creating extremes.

Summary: This study identified summer and annual drought events across Nepal from 1977 to 2018 using the Standard Precipitation Index (SPI). It found that there has been an increase in drought frequency since 2005. The worst drought years in Nepal were recorded in 1992 and 2015.
