The airborne microbiome is one of the relevant topics in ecology, biogeochemistry, environment, and human health. Bioaerosols are ubiquitous air pollutants that play a vital role in the linking of the ecosystem with the biosphere, atmosphere, climate, and public health. However, the sources, abundance, composition, properties, and atmospheric transport mechanisms of bioaerosols are not clearly understood. To screen the effects of climate change on aerosol microbial composition and its consequences for human health, it is first essential to develop standards that recognize the existing microbial components and how they vary naturally. Bioaerosol particles can be considered an information-rich unit comprising diverse cellular and protein materials emitted by humans, animals, and plants. Hence, no single standard technique can satisfactorily extract the required information about bioaerosols. To account for these issues, metagenomics, mass spectrometry, and biological and chemical analyses can be combined with climatic studies to understand the physical and biological relationships among bioaerosols. This can be achieved by strengthening interdisciplinary teamwork in biology, chemistry, earth science, and life sciences and by sharing knowledge and expertise globally. Thus, the coupled use of various advanced analytical approaches is the ultimate key to opening up the biological treasure that lies in the environment.

Society could sustain the impact of climate change by adapting to the change and mitigating risks from adverse effects of increasing changes, so that it can continue maintaining its prospect and improving wellbeing. Nevertheless, climate change is more or less affecting society's functions at different scales, including both individuals and communities. In this review, we discuss the relationship between society and climate change in China from the aspects of the needs at different socioeconomic developing stages. The relationship as well as the current spatial pattern and future risks of the climate change impacts on societies are summarized. The complexity of social and climatic systems leads to the spatial heterogeneity of climate impacts and risks in China. To more effectively leverage increasing knowledge about the past, we advocate greater cross-disciplinary collaboration between climate adaption, poverty alleviation and Nature-based Solutions (Nbs). That could provide decision makers with more comprehensive train of thoughts for climate policy making.

Release of carbonaceous aerosols - comprising black carbon (BC) and organic carbon (OC) - from biomass burning into the atmosphere is dependent on the burning conditions as to the resultant relative abundances of the emitted BC and OC. This provides a way of managing biomass burning in terms of manipulating the types of emitted aerosol. The carbonaceous aerosols are concerned in different ways in different scientific fields. The BC and OC exert complex implications for (a) radiative forcing in climate change science but (b) public health concern in air pollution science. Referring to these complex implications, a case of sustainability is constructed, which is being unsustainably dealt with at the crossroads of the sciences. This reveals an inadequacy of the reductionist mode of enquiry, necessitating a new mode with unique epistemological orientation for the scholarship of sustainability. The necessity of integration of perspectives that are currently segregated for this sustainability issue and the implications for sustainable development are elucidated.
