Summary: Using high-resolution satellite readings of soil moisture, climate-economy econometric models, and machine learning methods, we quantify the risk to global agricultural commodities from climate change. Our climate risk measure based on soil moisture fluctuations has a significant negative impact on the yield of major cereals, surpassing the effects of temperature and precipitation. This impact is concentrated in countries with lower income levels, harsher climate conditions, or less irrigated farmland. Furthermore, we demonstrate that agricultural commodities in countries with higher frequencies of past droughts are less vulnerable to current drought risks, suggesting adaptive learning from prior experience.

Summary: This study analyzes the impacts of climate change on agriculture in the Indus River Basin, finding an increasing trend in minimum temperature and historical precipitation, as well as continued warming and increased rainfall variability in future projections. These findings emphasize the importance of climate impact assessments for developing targeted investments and adaptation measures to ensure agricultural resilience in Pakistan.

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.

Summary: Fire weather compounded by extremely hot and dry conditions has severe impacts on society and ecosystems. A study finds that the frequency and intensity of compound fire weather (CFW) events have increased globally from 1981 to 2020. Temperature increase and relative humidity decrease are responsible for significant trends in CFW events, with anthropogenic climate change aggravating these trends.

Summary: According to the application of extreme value theory to Cenozoic foraminifera proxy records, multi-millennial hyperthermal events, like the Palaeocene-Eocene thermal maximum, are more likely to occur when the baseline temperature is higher. Oxygen isotopes in sediments reflect Earth's past temperature, showing a cooling trend over the Cenozoic interrupted by multi-millennial thermal extreme events. This study used global records of deep sea foraminiferal delta O-18 as a proxy for atmospheric temperature and found that the distribution of these extremes matches well with the generalized extreme value distribution, with larger thermal extremes being more likely in warmer climates. Therefore, anthropogenic warming has the potential to increase the likelihood of large thermal extremes by returning the baseline climate state to a warmer condition.

Summary: Temperature extremes with altered characteristics are one of the most threatening impacts of global warming. The study showed that globally, the intensity of heat extremes significantly increased while that of cold extremes decreased at a faster rate, leading to an overall decrease in extreme events. The trends varied across regions, with the most notable shifts observed in the Tropical and Polar zones.

Summary: The challenging alterations in climate in the last decades have had devastating implications on agricultural crop production and food security. Extreme environmental conditions offer opportunities to study the influence of microorganisms on plant development and agricultural productivity. This review emphasizes the mechanisms of plant growth-promoting microorganisms in adapting to environmental stresses and the importance of microbial community in improving sustainable crop production under changing climatic scenarios.

Summary: This study assesses current and future extreme climate changes in China using CMIP6 data. The results show that the downscaling method improves the spatial distribution of extreme climate events, and indicate an increase in precipitation and temperature in China. However, there are significant differences between different models, suggesting that future extreme climate events will have an uneven spatial distribution.

Summary: This commentary calls for a human geography that pays more attention to the complexities of understanding place in extreme and troubling times. It discusses how place is created, navigated, and enclosed during the climate crisis. It argues that in specific contexts, ordinary and mundane emotions and affective experiences can influence future thinking, grounding it in the present moment. It then examines how such conditions are produced and manufactured through extraordinary enclosures and analog spaces.

Summary: Most studies focus on climate extremes that occur once or more each year, but it is the less frequent events that have the largest impacts. Research indicates that rare climate events in southeast Australia are projected to increase in frequency in the future, with heat extremes showing the greatest change.

Summary: Heatwaves and extreme rainfall in India during the summer and summer monsoon seasons pose severe challenges. The risks and drivers of these sequential extremes have not been recognized. Our research shows that the mega-heatwaves and extreme rainfall events in 1995 and 1998 affected a significant portion of India. The area impacted by sequential extremes is higher during the positive phase (El Nino). If global mean temperature rises above 1.5 degrees C, the fraction of population and urban area exposed to sequential extremes will increase rapidly. Improvements in socioeconomic livelihood and infrastructure are necessary to reduce vulnerability and maintain the same level of risk at higher global warming levels.

Summary: The study develops a Machine Learning Water Systems Model (ML-WSM) to address the challenges in sustainable western US municipal water system (MWS) management. By applying the ML-WSM to the Salt Lake City water system, the researchers demonstrate that the model can accurately predict the seasonal dynamics of the different components and classify instances of vulnerability and severity. The findings suggest that the ML-WSM can be used as a guidance tool to evaluate the influences of climate on MWS performance.

Summary: This research focuses on the impacts of freshwater stress and storage loss on social and ecological systems. It finds that basins with existing freshwater stress are experiencing increasing drought, posing challenges to water stressed basins globally. By mapping the global gradient of social-ecological vulnerability to freshwater stress and storage loss, 168 hotspot basins are identified as the most vulnerable, encompassing over 1.5 billion people, 17% of global food crop production, 13% of global gross domestic product, and hundreds of significant wetlands. Reducing vulnerability in these hotspot basins can bring significant social and ecological benefits.

Summary: This study proposes a composite Boussinesq equation for estimating baseflow recession and storage-outflow relationship, which shows smaller errors compared to linear and nonlinear equations. The analysis of different variables reveals that nonlinearity increases in drier regions, while the relative errors of all three methods increase in wet climate regions.
