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: This study found that compound hot extremes (CHEs) are associated with an increased risk of injury mortality, and the projected burden of injury mortality attributed to CHEs is expected to substantially worsen in the future due to global warming. Particularly in southern, eastern, central, and northwestern China, the frequency and impact of CHEs on human health are predicted to increase significantly. Therefore, it is urgent to develop targeted adaptation policies to alleviate the health burden caused by CHEs.

Summary: The Southern Hemisphere Annular Mode (SAM), the dominant mode of atmospheric circulation in the Southern Hemisphere, has shown changes in its seasonal trend in relation to ozone recovery. The summer SAM trend has decreased since 2001, reducing the seasonal difference with winter, while the winter SAM has shown an increasing positive trend in the early 21st century, reversing the previous seasonality. The winter SAM changes are found to be part of a multidecadal oscillation, possibly originating from the Atlantic Multidecadal Oscillation.

Summary: This study evaluated the trends of reference evapotranspiration (ET0) in the Senegal River Basin, finding that regional climate models (RCMs) were more robust than global circulation models (GCMs). ET0 was found to be more sensitive to relative humidity, maximum temperature, and solar radiation, with significant increases projected in ET0, maximum and minimum temperatures in the period 2036-2065.

Summary: Environmental changes due to global warming will escalate the costs of combating climate change, especially the loss of climate regulation caused by declining snow cover. Different carbon mitigation approaches result in varied economic impacts, emphasizing the importance of international cooperation in reducing carbon emissions.

Summary: This study predicts a decreasing trend in future cropland N2O emissions in China using high-precision land use data, with a reduction in total emissions and cropland area. However, some cities in China are projected to emit more than current levels, and different land use and climate change scenarios will have significant impacts on cropland N2O emissions. The implementation of environmental projects, like the Grain for Green Plan, could effectively control emissions by about 12%.

Summary: Heat-related mortality in China is projected to increase due to climate change and population aging, even under low emission scenarios. Achieving the 1.5 degrees C warming target can significantly reduce the mortality burden. Carbon neutrality by mid-century is crucial for China's sustainable development.

Summary: The study demonstrates that ERA5 best reproduces Antarctic near-surface air temperatures in the early period and is also the most homogeneous reanalysis across the early and late periods, indicating a significant change in the relationship between Southern Annular Mode (SAM) and Antarctic near-surface air temperatures between the two periods.

Summary: From May to August 2018, the northern extratropics experienced prolonged heat waves with record-breaking temperatures, causing numerous deaths in cities. The heat waves in 2018 showed a circumglobal characteristic due to a circumpolar perturbation in the middle-upper troposphere of the Northern Hemisphere, consisting of a wavelike perturbation and an almost zonally symmetric hemispheric perturbation. The warming trend component of sea surface temperature, especially in the tropics, compounded by unusually large SST anomalies in 2018, played a significant role in inducing the circumpolar circulation anomaly that led to the extreme heat waves in the northern extratropics.

Summary: European windstorms cause socioeconomic losses, and future projections show an increase in these losses due to changes in storm frequency, intensity, and population. The use of storm severity indices from climate models reveals that storm frequency and severity will double and triple respectively, with adaptation measures only partially offsetting the increase in losses. However, following lower emissions scenarios can reduce the future risk, resulting in a more than halving of the population-weighted storm severity index increase.

Summary: Climate change with increasing temperature has a significant impact on human health, leading to more heat-related diseases and burdening the healthcare system. This study estimated heat-attributable hospital healthcare costs in Perth, Western Australia, and found that higher temperatures were associated with increased hospital costs. The findings emphasize the importance of climate change adaptation measures to reduce adverse health effects in Perth.

Summary: The study simulates climate models and finds that precipitation within extratropical cyclones is very likely to increase towards the end of the century. The models also show that future winter storms will bring more precipitation, with a focus on moderate and heavy rainfall and a decrease in frozen precipitation frequency.

Summary: The study found that the largest uncertainty in global drought projections comes from the uncertainties in general circulation models (GCMs), followed by bias correction (BC) and representative concentration pathway (RCP) uncertainties. Bias correction reduces the spread among GCMs in the Northern Hemisphere but can lead to larger uncertainties in some regions compared to GCM uncertainty. Overall, GCM and BC uncertainties decrease with time, while RCP uncertainty is expected to increase and even surpass BC uncertainty in certain regions by the end of the century.

Summary: Over the past four decades, changes in sea level pressure in Antarctica have impacted the climate of the South Pacific region. Research suggests that warming in the upper ocean of the subtropical southwest Pacific is a key factor contributing to the pressure trend dipole, influencing the central Chile megadrought.
