ABSTRACTClimate change jeopardizes human health, global biodiversity, and sustainability of the biosphere. To make reliable predictions about climate change, scientists use Earth system models (ESMs) that integrate physical, chemical, and biological processes occurring on land, the oceans, and the atmosphere. Although critical for catalyzing coupled biogeochemical processes, microorganisms have traditionally been left out of ESMs. Here, we generate a “top 10” list of priorities, opportunities, and challenges for the explicit integration of microorganisms into ESMs. We discuss the need for coarse-graining microbial information into functionally relevant categories, as well as the capacity for microorganisms to rapidly evolve in response to climate-change drivers. Microbiologists are uniquely positioned to collect novel and valuable information necessary for next-generation ESMs, but this requires data harmonization and transdisciplinary collaboration to effectively guide adaptation strategies and mitigation policy.

The American Academy of Microbiology convened a workshop bringing together scientists with varied opinions on the conduct of gain-of-function research of concern (GOFROC) and enhanced pathogen with pandemic potential (ePPP) research. Five findings were: (1) research on infectious agents is necessary for understanding, monitoring, and developing treatments and prevention measures against these agents; (2) gain-of-function research of concern or ePPP research makes up a very small fraction of all biological research; (3) clearly defined terminologies for research of concern should be developed by the scientific community to avoid public confusion and highlight its practical benefits; (4) harmonized biorisk management standardization, training, mentoring, and reporting can help improve safety and security for laboratory workers and the public; and (5) expanded engagement and collaboration of scientists with policymakers and the public, including increased transparency on the risks and rewards of research with infectious agents, is needed.

Change is an inevitable part of any organization if it wants to adapt and strive in a changing environment. That was what the American Academy of Microbiology (Academy) did from 2019-2023 when it transformed itself into a scientific think tank at ASM while maintaining the high standard of an honorific community of scholars. Here, we report on the recent history of the Academy and the changes that have taken place during this period. With the contribution of many thougtful leaders, the Academy refreshed its commitment to promote excellence and uphold its high values.

ABSTRACT Owing to the high radiative forcing and short atmospheric residence time of methane, abatement of methane emissions offers a crucial opportunity for effective, rapid slowing of climate change. Here, we report on a colloquium jointly sponsored by the American Society for Microbiology and the American Geophysical Union, where 35 national and international experts from academia, the private sector, and government met to review understanding of the microbial processes of methanogenesis and methanotrophy. The colloquium addressed how advanced knowledge of the microbiology of methane production and consumption could inform waste management, including landfills and composts, and three areas of agricultural management: enteric emissions from ruminant livestock, manure management, and rice cultivation. Support for both basic and applied research in microbiology and its applications is urgently needed to accelerate the realization of the large potential for these near-term solutions to counteract climate change.

ABSTRACT Climate change is a complex problem involving nonlinearities and feedback that operate across scales. No single discipline or way of thinking can effectively address the climate crisis. Teams of natural scientists, social scientists, engineers, economists, and policymakers must work together to understand, predict, and mitigate the rapidly accelerating impacts of climate change. Transdisciplinary approaches are urgently needed to address the role that microorganisms play in climate change. Here, we demonstrate with case studies how diverse teams and perspectives provide climate-change insight related to the range expansion of emerging fungal pathogens, technological solutions for harmful cyanobacterial blooms, and the prediction of disease-causing microorganisms and their vector populations using massive networks of monitoring stations. To serve as valuable members of a transdisciplinary climate research team, microbiologists must reach beyond the boundaries of their immediate areas of scientific expertise and engage in efforts to build open-minded teams aimed at scalable technologies and adoptable policies.

Since early 2020, the world has witnessed the unprecedented accomplishments of the scientific community in the fight against the coronavirus disease 2019 (COVID-19) pandemic. In the meantime, we also learned valuable lessons and recognized the challenges that hindered our successes.
