Summary: This study examines the socioeconomic factors influencing energy poverty in clean cooking in Bangladesh. It analyzes household characteristics that drive the choice of cleaner cook stoves and cooking fuels among different population segments. The findings reveal that houses with better ventilation tend to use less clean fuels and more primitive stoves. Renters, on the other hand, use cleaner fuels and technologies. Female or older-headed households have lower adoption rates of cleaner cooking solutions. Household wealth positively correlates with the choice of cleaner cooking options. Education and electricity access do not necessarily lead to higher adoption of cleaner cooking. Urban areas, particularly the capital city, show higher usage of cleaner cooking solutions. The study recommends increased distribution of cleaner fuels and stoves in rural regions and among lower income communities to achieve the national clean cooking target.

Summary: Exposure to household air pollution from solid fuel use causes millions of premature deaths globally, with direct leakage from stoves believed to be the main cause. On-site measurements using a newly developed method quantitatively evaluated the leakage of gases and particulate matter from different fuel-stove combinations, showing higher indoor leakage from biomass burning compared to coal combustion.

Summary: The concept of flame adaptability was proposed to address the mismatch between the combustion flame shape and the heating surface structure in stove chambers, aiming to improve energy utilization efficiency and reduce pollutant emissions. By establishing an evaluation model, it was found that adding an adaptive structure with appropriate parameters significantly reduced flame length and NOx emissions.

Summary: Using data from the China Kadoorie Biobank (CKB) study, this research investigated the relationship between the use of solid fuels for cooking and depression among adults in rural China. The study found that longer exposure to solid fuel use for cooking was associated with increased odds of having a major depressive episode. Therefore, reducing the use of solid fuels and promoting clean energy should be encouraged.

Summary: Microplastics pose potential threats to the Earth's environment and particularly to the cryospheric regions. They may enhance melting processes by affecting the albedos of snow and ice surfaces. It is therefore crucial to urgently conduct systematic studies on the radiative forcing effects of microplastics and evaluate their possible impact on cryospheric melting in the future.

Summary: This study investigates the characteristics and roles of carbonaceous matter (CM) in the Tibetan Plateau River Basin using precipitation and glacier samples. The results show that CM significantly affects the carbon cycle and radiative forcing (RF) of glaciers. Various sources of CM were identified, and two major pollution source areas were identified as well. Moreover, the optical properties of CM varied among different sample types. The study also estimated the RF of CM relative to black carbon (BC) in different sample types.

Summary: One-year online measurements in Lanzhou were conducted to investigate the variations in mass concentrations and light absorption characteristics of organic carbon (OC) and black carbon (BC) in PM2.5. The results showed clear seasonal variations, with the highest concentrations in winter. Fossil fuel combustion was identified as the primary source of carbonaceous components, and biomass burning contributed significantly to BC in winter. Brown carbon (BrC) was found to have a considerable impact on the total absorption coefficient, with higher contributions in winter.

Summary: The Indian monsoon circulation plays a crucial role in transporting mercury pollution from South Asia to the Himalayas and Tibet Plateau region. A study found a strong overlap between Lake Gokyo and Indian anthropogenic sources, indicating the source of mercury from South Asia. The findings suggest that transboundary atmospheric transport can transport mercury from South Asia northwards to at least the Tanglha Mountains in the northern Himalaya-Tibet.

Summary: South Asian biomass burning is crucial for the heavy springtime air pollution over the Tibetan Plateau, contributing significantly to aerosol components. The transboundary transmissions of these aerosols are regulated by large-scale westerly winds and regional mountain-valley winds. In addition to worsening air quality, aerosols from South Asian biomass burning also lead to temperature decrease and precipitation reduction, posing a threat to the fragile ecosystem of the Tibetan Plateau during springtime.

Summary: Organic aerosols have significant impacts on the Tibetan Plateau, a region highly sensitive to climate change. Studying the concentration and sources of organic molecular tracers, it was found that biomass burning plays a major role in non-monsoon seasons, with significant impacts from South Asian biomass burning in the western, southern, and southeastern regions.

Summary: This study analyzed the changes in river discharge and sea ice in the Kara and Laptev Seas from 1979 to 2019. The results showed that there were significant increases in discharge and heat from the rivers, while the sea ice concentration decreased. The changes in discharge and riverine heat mainly affected the initial and final stages of sea-ice melting. The cumulative riverine heat from May to September had a large impact on the sea ice changes in the Kara and Laptev Seas. However, the contribution of river discharge changes to the reduction in sea ice concentration was limited at annual scales.

Summary: The navigability of Arctic maritime passages has improved with the retreat of sea ice, but it also brings potential environmental and climate risks. This investigation studied shipping emissions and climate impacts along the Northern Sea Route under different global warming scenarios. The results show that ship energy consumption is 109 kWh under 2°C and 3°C global warming. Environmental impacts decrease with the use of clean fuel sources, and CO2 has the greatest climate impact.
