Microbes in tree bark consume heat-trapping gases, potentially reducing millions of tonnes of emissions yearly.
Microscopic microbes in tree bark are found to consume methane, hydrogen, and carbon monoxide—gases that drive global warming—potentially removing millions of tonnes annually, according to Australian researchers.
The study, involving 80 tree species over five years, found wetland trees like paperbark (Melaleuca) host higher microbial populations due to greater moisture.
Though soil microbes have long been studied, bark was overlooked despite its vast global surface area.
This discovery reveals trees offer dual climate benefits: absorbing carbon dioxide and filtering harmful gases, which could reshape reforestation and urban greening strategies.
Los microbios en la corteza de los árboles consumen gases que retienen el calor, reduciendo potencialmente millones de toneladas de emisiones al año.
