Summary: Globally, changing climate and disturbance events are increasingly challenging the resilience of forest ecosystems. Regeneration failure can result from the interplay among disturbance changes, altered climate conditions, and functional traits. In the Greater Yellowstone Ecosystem, a substantial portion of forested area failed to regenerate, especially in areas where fires are not constrained by topography and in high-elevation forest types not adapted to fire.

Summary: The Guangdong-Hong Kong-Macao Greater Bay Area has undergone rapid urbanization in the past four decades and is rich in meteorological observation resources, making it an ideal location for urban climate studies. Research in the region has focused on urban climate characteristics and variations, challenges brought by urban climate change, and technologies and strategies to mitigate and adapt to these changes.

Summary: The study found that smaller diameter whitebark pine trees were not proportionally more abundant at lower elevations, suggesting that competitive exclusion may not be the primary mechanism limiting this species' distribution at lower elevations. However, smaller diameter whitebark pine trees were slightly less warm-dry tolerant than larger individuals, indicating a shift in the regeneration zone towards higher elevations possibly due to warming in the Greater Yellowstone Ecosystem. The predicted zone of suitable habitat for smaller diameter whitebark pine trees was 122 meters lower in elevation compared to reproductive-sized trees in previous studies, implying that the species may be slightly less sensitive to climate warming but could still face range contractions in the future.

Summary: Formally protected areas are important for wildlife conservation, but they may not be effective for migratory species. In the Greater Yellowstone Ecosystem, migratory elk rely on both protected areas and private lands, facing challenges such as habitat fragmentation from human development. Future conservation strategies need to consider coordination between public and private land to ensure migratory connectivity.

Summary: This study used tree-ring width and normalized difference vegetation index to establish a model, reconstruct annual vegetation index maps, and discovered trends of forest decline and regime shifts. The research showed a decrease in vegetation density over the past 100 years and identified several major regime shifts caused by significant climate events.

Summary: The study finds that consumers have concerns regarding safety and ethics, lack trust in automated vehicles, and hold diverse opinions on the role of the public sector and regulation strategies. It highlights the importance of considering psychosocial explanations in the adoption of new technology for policymakers.

Summary: From July to August 2022, there was an unprecedented bleaching event in the scleractinian coral communities of China's Greater Bay Area in the northern South China Sea. Despite being considered coral thermal refugia, bleaching occurred at all surveyed sites, with more severe bleaching in shallow water. Acropora and Pocillopora were highly susceptible to bleaching and had high post-bleaching mortality.

Summary: The study investigates the potential impacts of future climate change in the headwater area of the Yellow River Basin on the Qinghai-Tibetan Plateau. Results show that with warmer and wetter climate, actual evapotranspiration is expected to increase significantly, leading to a decrease in water supply and a worsening water crisis.

Summary: Increasing extreme precipitation caused by climate change and human activities may have severe consequences on people's lives and property. This study investigates the effect difference of urbanization, climate change, and their compound effect on extreme precipitation under various scenarios. The results show that annual and total precipitation will be more intense and frequent at a regional scale, and future urbanization exacerbates precipitation at a local scale.

Summary: The study demonstrates the effectiveness of using the WRF model for high-resolution climate projections in the GBA, especially in simulating spring and summer precipitation and extreme rainfall events. It predicts an increase in heavy rainfall events in the future, with significant temperature changes expected across different seasons, particularly a rapid warming in autumn, and more summer days leading to an increased risk of heatwaves and heat stress in the GBA.

Summary: Carbon prices in the EU ETS have significantly increased in recent years, possibly due to the implementation of the cancellation mechanism in the Market Stability Reserve. This mechanism has resulted in massive cancellation of emissions allowances, leading to higher carbon prices. These findings have important implications for the planned revisions of the EU ETS.

Summary: The impacts of near-future urban development and global warming forcing on hourly extreme rainfall over the South China Greater Bay Area (GBA) were investigated. The results show that both climate change and rapid urban development have comparable positive effects on rainfall intensity and heavy rainfall probability over the GBA urban area. Global warming tends to increase heavy rainfall probability, but suppresses the probability of light rainfall. Urban development increases urban rainfall probability, with a significant increase in frequency for very heavy rainfall.

Summary: This study analyzed the variability of NPP and its drivers in the Guangdong-Hong Kong-Macao Greater Bay Area from 2000 to 2020. The results showed that climate variability and human activities were the major driving factors of NPPa increases and can provide a reference for ecosystem restoration and conservation practices in the GBA.
