Summary: This study investigates the cooccurrences of heat and air pollution extremes in China. The results show a significant increase in the frequency of joint exceedances of wet-bulb temperature (w) and O-3, mainly in the Beijing-Tianjin-Hebei region and the Yangtze River delta. Moreover, the rate of joint exceedance is higher than the rate of T-w and O-3 themselves.

Summary: This study investigates the projected surface mean temperature changes over China and its four sub-regions using data from 20 models of the Coupled Model Intercomparison Project Phase 6 (CMIP6). It shows that China is expected to experience increasing temperatures, with accelerated warming in Northwestern China and the Tibetan Plateau. The main sources of uncertainty for future temperature projections in China are identified as model and scenario uncertainty, particularly in regions with the largest cold bias.

Summary: This paper investigates the vegetation dynamics of the Loess Plateau in China and finds a significant greening trend. Human activities are identified as the main driver of vegetation variation, particularly reforestation and land-use change. The study highlights the importance of monitoring vegetation changes in fragile ecosystems for ecological restoration planning.

Summary: Understanding the dynamic of vegetation is crucial for revealing the structure and function of an ecosystem in the context of global warming. This study analyzed the trends of vegetation in northern China from 1982 to 2015 and quantified the impact of climate change and human activities on vegetation change. The results showed significant changes in over 53% of the vegetation, with potential risks of degradation in certain areas.

Summary: Southern Ocean primary productivity is affected by light and iron limitation, but the factors determining iron availability, accessibility, and demand are uncertain. In this study, we analyzed long-term data collected by Biogeochemical Argo floats and ship-based platforms to examine the effects of iron stress on phytoplankton photophysiology. We observed a significant multidecadal trend of increasing iron stress and declining regional net primary production. This trend is attributed to changes in the Southern Ocean mixed-layer physics and complex biological and chemical feedback, highlighting important ongoing changes in the Southern Ocean carbon cycle.

Summary: The study found that the Taihang Mountain region has experienced an average warming of 0.3 degrees C/decade over the past five decades, with seasonal variations in warming rates. Elevation and latitude were significantly negatively correlated with temperature, but not with the temporal warming trend. The Z value was significantly negatively correlated with percent forestland and positively correlated with GDP, suggesting the impact of economic development and afforestation on temperature changes in the region.

Summary: The study found that the long-term trend shift of PBLH in China is related to changes in surface upward sensible heat flux, low cloud cover, and soil moisture. These factors directly influence the energy balance, highlighting the importance of considering them in climate models for accurate PBLH simulations.

Summary: The study investigated the impacts of climate change and human activities on vegetation dynamics in mainland China, with the finding that land use changes have a greater influence on vegetation changes than temperature and precipitation changes. Activities such as planting trees and returning farmlands to forests have increased the coverage of grasses and mixed forests, while cultivated vegetation has decreased. The improved residual trend method was shown to reduce uncertainty in quantifying the effects of climate and anthropogenic factors on vegetation dynamics, providing a theoretical basis and tool for future ecological management strategies by the government.

Summary: Global warming and anthropogenic activities have significantly impacted rainfall patterns in northern Australia in recent decades. The study found an increasing trend in annual precipitation across the region with higher variation. The main shifting period of rainfall patterns was observed during 1966-75. While annual rainfall seems to become wetter, the frequency of extreme rainfall events should also be considered in assessing the impacts of climate change.

Summary: Understanding future variations and trends of heatwave events is crucial for the ecosystem and human health. However, the diverse metrics of heatwaves affect the comparability of regional assessments. Inadequate consideration of local conditions undermines the comprehensive understanding of future heatwave changes.

Summary: Public opinion can greatly influence public policy, and in the face of the current climate crisis, shaping public opinion can be a way to drive the adoption of climate policies. By analyzing the impact of major media events on public interest and concern for climate change, Google Trends was identified as a reliable tool for evaluating changes in public attention. The "Greta Thunberg effect" in 2019 led to a shift in concern, with decision-makers showing more concern for climate change than traditionally vulnerable countries. This created a high demand for strong climate policies and future public actions to address the ongoing climate crisis.

Summary: The study found that alpha(c) in the Loess Plateau exhibits spatial and temporal variability, primarily influenced by aridity index (AI) and average Normalized Difference Vegetation Index (NDVI) during the growing season. The quantified impacts of climate change (mainly expressed by an increase in precipitation) and revegetation (quantified by the NDVI increase) showed that climate change contributes the most to the ET increase (approximately 68% on average), while revegetation also plays a significant role (approximately 32% on average), highlighting the importance of managing water consumption by evapotranspiration in sustainable development.
