As the most abundant organisms on Earth, microorganisms make considerable contributions to, and are greatly affected by, a changing climate. Microbes are major drivers of elemental cycles (such as carbon, nitrogen and phosphorus), important producers and consumers of greenhouse gases, and pertinent pathogens of humans, animals and plants. It is critical to learn how the impacts of a changing climate will impact microbes and their relationships with humans and the environment. On April 22, 2022, the American Academy of Microbiology (Academy), the honorific leadership group of ASM, published a report based on the deliberations of experts who participated in a colloquium on November 2021. The Academy's Climate Change and Microbes Scientific Portfolio is a committment to continue focusing on understanding the relationship between microbes and climate change over the next 5 years. 
 

Advocating for Climate Change Solutions

Advocacy

ASM advocates for continued support for research and policies that facilitate the translation of microbial research to real-world, scalable solutions in renewable energy, water quality and sustainable ecosystems. These efforts will require Congressional support and interagency coordination on an unusually grand scale.

As ASM works with policymakers to ensure that science is front and center in policy approaches to climate change, we strongly encourage scientists to bring their expertise to bear on climate change mitigation, adaptation and resilience.  
 

ASM Policy Recommendations

Few policymakers understand the contributions of microbes to the generation and consumption of warming gases, to ecosystem stability, and to human well-being. To that end, ASM has developed a policy brief with recommendations urging adequate infrastructure, funding and coordination to support microbiologists who are developing and deploying climate solutions.

Panel Discussion


 

Microbes are adept at adapting, surviving and thriving in extreme and constantly changing environments. ASM leadership hosted a virtual panel during the United Nations General Assembly (UNGA) Science Summit discussing the role and contribution of science to the attainment of the United Nations Sustainable Development Goals (SDGs). The SDGs include 17 interconnecting global objectives identified by the UN as a "blueprint to achieve a better and more sustainable future for all" by 2030.

Microbes Are Critical to Soil Health

Microbes play a critical role in the functioning of soils, which are a key natural resource in adapting to and mitigating climate change.
