Summary: Supraglacial debris affects glacier mass balance by either enhancing or reducing surface melting. Accounting for debris can reduce sub-debris melt by up to 37%, impacting regional mass balance by 0.40 m water equivalent per year. Recent observations suggest differences in ice dynamics are the primary reason for thinning rates over debris-covered and clean ice glaciers.

Summary: Despite the importance of in situ glacier mass balance for regional water resource planning and climate change indicators, records in the Himalaya are limited. This study presents updated measurements of the mass balance of Rikha Samba Glacier in Nepal between 2011 and 2021. The study also uses a model to extend the mass balance series back to 1974. The findings show that the modeled mass balance is consistent with in situ measurements and previous estimates, indicating significant mass losses in line with other Himalayan glaciers.

Summary: Debris-covered glaciers, with their insulating effect of supraglacial debris, exhibit a more complex response to climate change compared to debris-free glaciers. Numerical modelling reveals that thick debris cover delays the volume and length response of glaciers to a warming climate signal, while cryokarst features like ice cliffs and supraglacial ponds enhance the length response and lead to substantial mass loss and thinning on debris-covered tongues.

Summary: This study reconstructs the glacier-wide mass balances of the Gangotri Glacier System and its individual glaciers using a temperature-index model. The results show negative mass balances for Gangotri and Meru glaciers, while positive mass balances for Chaturangi and Raktavaran glaciers. The positive mass balances on the fragmented tributary glaciers are attributed to non-climatic topographic reasons, and should not be confused with climate change denial or the Karakoram Anomaly.

Summary: The study investigated the dimensional and mass balance changes of Dokriani Bamak and Chhota Shigri glaciers in the central and western Himalayas over the past seven decades. Both glaciers experienced deglaciation and retreat since 1968, with accelerated rates in the twenty-first century. Mass balance was found to significantly influence the deglaciation and retreat of both glaciers.

Summary: This study focuses on the importance of future glacier changes for the sustainable use of regional water resources and the survival and development of the densely populated Tibetan Plateau and surrounding regions. A distributed energy-mass balance model is used to simulate the historical and future mass balance and ice volume of Qiyi Glacier from 1980 to 2100. The study aims to illuminate the spatial and temporal patterns of mass balance and energy balance, forecast future changes under different scenarios, and identify the timing of peak ice loss.

Summary: We quantified the surface elevation changes of Yala Glacier in Nepal Himalaya using geodetic methods. Our analysis shows a continuous surface lowering trend in the down-glacier area, with recent years experiencing an up-glacier propagation. The calculated mass-balance data indicate accelerated mass loss in Yala Glacier since the late 2000s, consistent with previous studies.

Summary: Improving knowledge of Himalayan glaciers mass balance is crucial for understanding current and past atmospheric variations, as well as future water availability. The study of Patsio Glacier in the western Himalayas revealed a cumulative mass balance over seven years with consistent winter mass balance values, showing a positive correlation with annual and winter precipitation in the region. Monitoring seasonal mass balance and considering non-climatic parameters like debris and aspect are important for accurate estimation of glacier-wide mass balance.

Summary: This study presents geodetic mass-balance estimates for glaciers around Volcan Domuyo between 1962 and 2020. The overall mass balance for this time period is slightly negative. However, closer inspection reveals an increasingly negative mass balance over time. The observed glacier changes are likely driven by an increase in summer temperatures and a decrease in winter precipitation. The findings suggest that glacier wastage is occurring at a wider geographical scale in the Central Andes.

Summary: The study utilized an urban canopy model coupled with a regional climate model to simulate energy fluxes, air temperature variability, urban-heat-island characteristics, indoor temperature variation, and anthropogenic heat emissions in Berlin. Results showed that the improved model reproduced observed turbulent heat fluxes and urban heat island effects, with better performance in winter simulations compared to those without the building energy model, while also realistically reproducing indoor air temperature variations in summer.

Summary: This study presents a comprehensive inventory of future glacial lakes in High Mountain Asia by analyzing the subglacial bedrock of approximately 100,000 glaciers. It identifies numerous overdeepenings that could potentially lead to glacial lake outburst floods (GLOFs), with a shift in lake area, volume, and hazard towards the Karakoram region from the southwestern Himalayan region. The findings provide valuable insights for anticipating emerging threats and potentials related to glacial lakes in the region.

Summary: The annual precipitation over the Tianshan Mountains showed a transition towards an increasing trend in the late 1980s, influenced by atmospheric circulation factors. Winter precipitation is affected by multi-decadal oscillations, while summer precipitation has a multi-decadal scale. Various teleconnection patterns impact the precipitation patterns in different seasons over the Tianshan Mountains.

Summary: The Tianshan Mountains, as a water tower, receive high precipitation levels in Central Asia. This study utilized data analysis to reveal the spatial and temporal patterns of precipitation over the region, showing distinct seasonal variations in precipitation. Different sub-Tianshan regions exhibit varying trends in precipitation, with Eastern Tianshan entering a humid period since 1986 and Western Tianshan experiencing increasing precipitation in summer and autumn.

Summary: Cost-effective sensors have become popular for measuring ambient and indoor particulate matter concentration, but their data reliability is hindered by sensitivities to temperature and relative humidity, especially in mobile measurement setups. Quantile mapping is identified as a useful calibration methodology for mobile measurements, retaining spatial characteristics of the data, albeit without a common correction factor. A well-elaborated measurement plan is crucial for successful application of quantile mapping in mobile measurements.

Summary: This study conducted year-round temperature and current measurements at depths of 58-392 m in Lago Grey, a 410 m deep glacial lake in Patagonia, to investigate the thermal structure and seasonal variations. The research revealed significant impacts of subglacial discharge on the lake's thermal condition, with the coldest temperatures observed below a depth of -100 m in mid-summer under the influence of glacial discharge. The data suggests that subglacial discharge and bathymetry play a key role in dictating mass loss and the retreat of lake-terminating glaciers.

Summary: This study used dendroclimatological techniques to investigate the sensitivity of different tree species in inner city of Berlin to the urban heat island. The results showed that urban trees are more sensitive to climate compared to rural trees, with deciduous species being sensitive to summer heat and drought, while conifer species are suitable for analysis in late winter and early spring. Urban trees can be used for climate response analyses and provide new pathways for tracing urban climate change, specifically the urban heat island.

Summary: The study presented new glacio- and isotope-geochemical data from a firn core retrieved from an ice cap on Plateau Laclavere (LCL), northern Antarctic Peninsula, covering 2012-2015. The research identified signals of two volcanic eruptions and two forest fire events in South America in the ice core records. The study also revealed stable annual snow accumulation, lack of seasonal cyclicity in isotopic records, and significant surface melt events during the austral summers of 2013 and 2015 in the LCL region.
