Summary: Global warming influences Earth's cloud cover, which plays a crucial role in the uncertainty of Equilibrium Climate Sensitivity (ECS). Through analyzing how clouds respond to environmental changes, global cloud feedback is constrained to 0.43 +/- 0.35 W·m-2·K-1, indicating a robust amplifying effect of clouds on global warming. This approach is expected to provide tighter constraints on climate change projections and its various socioeconomic and ecological impacts.

Summary: This study conducted a global meta-analysis of 656 pairwise observations to analyze the responses of plant, soil, and microbial carbon and nitrogen pools and fluxes to extreme weather events. The results showed that extreme drought, heavy rainfall, and extreme heat decreased plant biomass and carbon flux, while extreme drought and heavy rainfall decreased plant nitrogen pools and soil nitrogen flux. These findings suggest that extreme weather events weaken the carbon and nitrogen cycling process in terrestrial ecosystems. However, the study did not determine the impact of extreme cold on ecosystem carbon and nitrogen cycling. Additional field experiments are needed to reveal the effects of extreme cold on global carbon and nitrogen cycling patterns.

Summary: This paper evaluates the univariate and compound extreme events in lakes worldwide using satellite observations, revealing that the intensity of lake heatwaves and high chlorophyll-a extremes varies across lakes and is primarily influenced by the annual range in surface water temperature and chlorophyll-a concentrations. Compound extreme events occur more frequently than assumed in most studied lakes, potentially causing more severe impacts on lake ecosystems than previously reported due to the occurrence of univariate extremes.

Summary: If effective mitigation measures are not taken, ongoing global warming will continue throughout the century. This is associated with the occurrence of extreme climate events in Africa. Using model data from 24 CMIP6 modeling centers, this study investigates future changes in extreme climate events over Africa under different global warming levels. The results show that additional warming amplifies the impact of climate extremes, stressing the need for ambitious climate change mitigation measures to limit global warming.

Summary: Regional anthropogenic warming caused stronger and shorter cold events during the winter of 2020-21, particularly in East Asia. Unlike previous cold events, these extreme cold events were a result of meridional circulation changes due to anthropogenic warming. The study highlights the significant role of anthropogenic factors in cold events.

Summary: Daily precipitation extremes are projected to intensify with increasing moisture under global warming following the Clausius-Clapeyron (CC) relationship at about 7%/?C. However, this increase is not uniformly distributed. By leveraging theory and observations of precipitation probability distribution, we can improve intermodel agreement and interpret projected changes more accurately. As a result, risk due to regional enhancement of precipitation scale increase by dynamical effects must be included in vulnerability assessment even if locations are imprecise.

Summary: The costs of climate change are often expressed in monetary terms, but this brings up ethical concerns. This study calculates the costs in terms of the number of people excluded from the 'human climate niche', which represents the historically consistent distribution of population density with respect to temperature. It was found that current climate policies leading to 2.7 degrees C global warming by the end of the century could leave one-third of the global population outside this niche, emphasizing the urgency for decisive action to address climate change.

Summary: Plant litter decomposition is an important process in ecosystems, but little is known about the bacterial communities' role in regulating this process in temperate wetlands under climate warming. This study aimed to investigate the effects of temperature on litter decomposition and the related bacterial mechanism. The results showed that decomposition rate was positively correlated with temperature, with non-additive effects observed in certain mixtures of plant species. Different types of litter also exhibited varying degrees of temperature sensitivity.

Summary: Colombia is vulnerable to climate change, especially due to regional deforestation. This study examines the impact of historical land cover changes and global warming on temperature and precipitation in Colombia. The results show that anthropogenic climate change has led to a temperature increase and increased precipitation, while land cover changes have reduced precipitation. La Nina events have a stronger impact in the Andes region compared to El Nino, but a weaker impact on the coast. Accurately accounting for both land cover changes and global warming is important for hydroclimatic assessments.

Summary: This study used climate models to investigate the impact of climate change on extreme ocean warming events around Japan. The research found that extreme ocean warming events have been increasing in recent years, especially in southern Japan. Climate change has significantly increased the probability of these events since 2000. Furthermore, the study concluded that limiting global warming to 1.5 degrees Celsius can greatly reduce the likelihood of future normal climate exceeding historical record high sea surface temperatures.

Summary: The rise of global mean temperature has attracted widespread attention in the scientific community, with efforts to limit global warming to 1.5 degrees C. Research shows that global warming leads to increased extreme precipitation and poses risks to economies and populations, especially in Asia and Africa which are more sensitive to climate change.

Summary: Aviation's contribution to global warming exceeds common perceptions, with a significant impact from a mix of climate pollutants despite a relatively low CO2 emission rate. Forecasted simulations suggest that aviation's warming contribution will continue to rise, but measures such as reducing air traffic scale or transitioning to carbon-neutral fuels can effectively mitigate its impact.

Summary: Thinning did not significantly affect litter decomposition rate, while understory removal markedly restricted litter mass loss. Although soil microbial abundance decreased after understory removal, it was not the main reason for the reduction in litter decomposition rate.

Summary: Soil aggregates play a crucial role in soil C sequestration by enhancing soil C stability and reducing soil C loss, regardless of land use types. The effects of N addition on soil C mineralization vary in different land use types, with N addition decreasing SOC mineralization in forest soils but increasing that in paddy soils.

Summary: The influence of litter quality and soil mesofauna on litter decomposition was studied in a subtropical forest ecosystem. It was found that higher quality litter decomposed faster in the early stage and had a larger fraction of stable residue remaining in the late stage. Soil mesofauna exclusion had no effect on the early decomposition rate but significantly increased the stable residue remaining.
