Summary: This study investigates the growth resistance and resilience of forests in response to extreme droughts of different durations. The findings show that growth resistance and resilience are higher in humid regions compared to arid regions. The study also reveals that the impacts of climatic factors on growth resistance and resilience weaken as drought duration lengthens, with plant functional traits and soil properties becoming more important. Furthermore, the study highlights the need to improve the performance of Earth system models in accurately predicting growth resistance and resilience under drought conditions.

Summary: The forest in the Tianshan Mountains has been experiencing a decline in growth and an increased mortality rate due to severe droughts, posing a threat to the ecosystem services they provide. This study examined the post-drought recovery of dominant tree species using tree-ring proxy data and found that post-drought moisture conditions played a crucial role in determining tree growth recovery. The findings highlight the importance of climate conditions and precipitation in managing and conserving forests in response to extreme drought events.

Summary: Climate change has increased the frequency and intensity of droughts and heat waves, impacting the growth and mortality risk of forests. The effects of thinning on species' responses to climate variation are highly variable, especially for broad-leaved species. This study assessed the effects of thinning on the growth sensitivity and response to extreme drought events of Eucalyptus grandis. The results showed that increasing thinning intensity improved the growth capacity and reduced the sensitivity to water balance, especially for two-stage thinning.

Summary: The increasing frequency and severity of heatwaves due to climate change have led to significant impacts on the terrestrial biosphere. Studies have shown that during heatwaves, soil respiration rates increase by approximately 26% on average. Failure to capture these high frequency extreme heatwave events may underestimate the terrestrial feedback to the carbon cycle.

Summary: This study examines how trophic state affects the response of reservoir ecosystems to extreme climatic events using long-term data. The results show that the response of reservoirs to extreme climatic events weakens when nutrient loading is reduced. Therefore, protecting reservoirs from nutrient pollution can improve ecosystem health.

Summary: It is projected that extreme drought events will become more frequent and severe across many regions of the globe by the end of the 21st century. However, our understanding of how different ecosystems respond to droughts, including their resistance and resilience, remains unclear. This study used carbon flux data from forest and grassland ecosystems to reveal their different responses to two extreme summer droughts. The findings show that the carbon fluxes and seasonal patterns vary between forest and grassland, and are influenced by different climate factors. The results also suggest that both forest and grassland experience reduced carbon sequestration during droughts.

Summary: The soil bacterial microbiome plays a crucial role in ecosystem functioning. Organic fertilization can enhance the resistance and resilience of bacterial communities in extreme drought and subsequent rewetting compared to conventional fertilizers. This study indicates that organic fertilization can enhance the stability of the soil microbiome and ensure the recovery of specific bacterial-driven ecosystem functions after rewetting.

Summary: Recent research suggests that exposure to extreme weather events often leads to the formulation of local adaptation policies, while mitigation policies are less common. Policy changes are influenced by event characteristics and local contextual factors, without a clear formula for local policy actions. A more robust theoretical framework and analysis of key combinations of factors are called for to improve local policy decisions in line with Dietz's criteria for environmental decision-making.

Summary: The use of Seasonal Livelihood Programming (SLP) as a resilience planning tool in rural Zimbabwe is relevant and beneficial in designing context-specific interventions against weather-induced shocks. The SLP tool adds value to the planning processes by analyzing seasonality, livelihoods, vulnerability profiles, and partnerships, which contribute to the development of drought mitigation strategies. However, it is crucial to integrate resource mobilization and explore community capacities for executing the proposed interventions.

Summary: Climate change legacies influenced the resistance and resilience of soil bacterial and fungal abundance to a subsequent extreme drought event, but not those of their community composition, richness, and multifunctionality. Specific microbial taxa play a crucial role in maintaining soil multifunctionality and recovering from extreme drought events predicted under anthropogenic climate change.

Summary: This study explores how local resilience structures in England can be utilized to achieve a comprehensive response to extreme heat events with the participation of the whole society. Based on a literature review, the study draws insights from research on health emergency response and extreme heat events in England. The findings suggest that local resilience forums play a critical role in addressing extreme heat events by tailoring information and resources to specific target groups within communities.

Summary: Understanding the responses of Mediterranean forests to extreme droughts and forest densification is crucial for land management. A study in eastern Spain found that semi-arid holm oak woodlands had lower resistance and resilience to drought compared to sub-humid and dry-transition conditions. The vulnerability of these semi-arid woodlands may affect the long-term stability of these forests. Adaptive management strategies and natural rewilding can improve drought responses in different climate conditions.

Summary: This study quantified the bioclimatic sensitivity of tree growth under different seasonal extreme drought/wetness regimes over the extra-tropical Northern Hemisphere from 1951-2013. The researchers found a negative asymmetry in tree growth under regimes with seasonal extreme droughts, with arid and temperate dry regions being more negatively impacted by pre-growing-season (PGS) extreme droughts. Angiosperms are more sensitive to PGS water availability, while gymnosperms are more sensitive to legacy effects of preceding tree growth conditions.

Summary: In recent years, the frequency and intensity of drought in South Korea have increased due to climate change, leading to increasing socio-economic damage. The concentration of precipitation in the summer and water shortage caused by population growth and urbanization contribute to the severity of droughts. Comprehensive assessment of multiple factors is essential for planning effective drought mitigation strategies.
