Summary: This study analysed precipitation and temperature biases from a set of Regional Climate Models in the South American CORDEX domain. The results showed a warm bias in central Argentina during the summer season, possibly due to an overestimation of incoming shortwave radiation. The models also overestimated precipitation in the northeast of Brazil during summer, which could be attributed to underestimation of moisture flux convergence and relative humidity at lower levels. These biases could affect the climate change signal and are linearly linked with warming levels in the models, with statistical significance at 95% confidence level.

Summary: Projected changes in extreme snow-related indicators show decreases in the continental US and southern Canada, but increases in Alaska and northern Canada by the late 21st century. California and the Pacific Northwest are expected to experience an increase in extreme runoff potential, potentially leading to larger rain-on-snow floods. Regions with high variability among model ensembles need further investigation to reduce regional uncertainties.

Summary: Representing the rainy season of the maritime continent poses a challenge for global and regional climate models, with high-resolution global climate models from the HighResMIP experiment showing better performance than regional climate models based on CMIP5. HighResMIP models simulate the onset date and total precipitation of the rainy season in Southeast Asia more accurately, while HighResSST experiment performs similarly to low-resolution models in simulating monsoon characteristics.

Summary: This study investigated the distribution and morphological traits of termite diversity globally and in China. It found that termite species richness increased with decreasing latitude, and termite morphological traits showed a latitudinal trend with decreasing body size and leg length at higher latitudes. Temperature, NDVI, and water variables were identified as the most important drivers of termite richness variation, while temperature and soil properties drove the geographic distribution of termite morphological traits. The study's global termite richness map provides a valuable baseline for further ecological analysis.

Summary: Leaving no one behind is the core objective of the 2030 Agenda for Sustainable Development. Latin America and the Caribbean face social inequalities despite a projected increase in population to nearly 760 million by 2050. Accurate and spatially detailed datasets are crucial for informing and supporting environmental, health, and developmental applications at subnational levels. To address the under-utilization of existing datasets, an open-access repository of high-resolution gridded population datasets for 40 countries in Latin America and the Caribbean has been developed using official statistics at the finest level of administrative units. These datasets, generated and validated using a top-down approach, provide population distribution information at a resolution of 3 arc-seconds and are available from the WorldPop Data Repository.

Summary: This study analyzed 10 high-impact extreme precipitation events in Southeastern South America during the warm season using statistical and dynamical downscaling approaches. It was found that higher horizontal resolution models had better simulation performance, while statistical downscaling techniques tended to overestimate spatial extension and underestimate intensity. Convective-permitting simulations showed good performance in reproducing rainfall patterns and triggering mechanisms due to strong initial condition control.
