摘  要:The intense heatwaves of 2023 and 2024 underscored the serious health,food security,and well-being risks posed by extreme heat,emphasizing the urgent need to curb greenhouse gas(GHG)emissions,especially methane(CH_(4)),which is 28 times more potent than carbon dioxide and primarily emitted through agriculture,fossil fuels,and waste(U.S.Environmental Protection Agency,2024).Cattle alone contribute approximately 231 billion pounds of CH_(4)annually,and rice cultivation is expected to increase by 9.9 billion tonnes by 2050(U.S.Environmental Protection Agency,2020).To effectively address this challenge,it is essential to balance microbial processes involved in CH_(4)production with sustainable agricultural practices—such as cultivating low-emission rice varieties,leveraging methanotrophs,and adopting efficient,low-methane livestock diets—as highlighted by the American Academy of Microbiology’s Microbes&Climate Change colloquium(2022).Achieving the COP28 Global CH_(4)Pledge’s 30%reduction goal by 2030 necessitates prioritizing these strategies.
