Explore the hidden world of microbes and their outsized impact on our planet in this episode of the Climate Emergency Forum. The discussion uncovers how these “tiny titans” are not just passive inhabitants of Earth, but active drivers of climate processes. From producing oxygen and cycling carbon to influencing greenhouse gas emissions, microbes are at the heart of the climate system—yet remain largely overlooked in both science and policy.
This video was recorded on April 9th, 2025, and published on April 20th, 2025, and represents the opinions of the discussion participants.
The discussion delves into the latest scientific consensus, highlighting that microbial-driven greenhouse gas emissions are rising and creating feedback loops that accelerate climate change. The conversation spans the crucial roles of marine phytoplankton, soil microbes, and the alarming decline of diatoms, as well as the challenges posed by ocean acidification and permafrost thaw. The panel emphasizes the urgent need for more research and systems thinking to fully understand and harness microbes’ potential for climate solutions, from carbon sequestration to methane mitigation and bioremediation.
Beyond their environmental significance, the dialogue explores fascinating intersections between microbes, human health, and society—such as the symbiotic relationships within our own bodies and the evolutionary history of life on Earth. The episode concludes with a call for greater public engagement, advocating for citizen science initiatives and broader collaboration to bridge the gap between scientific discovery and policy action. Don’t forget to like, subscribe, and join the conversation as we uncover how respecting and understanding these microscopic powerhouses could be key to restoring a livable climate.
