Methane, a potent greenhouse gas, is rapidly accumulating in the atmosphere, posing a critical threat to the planet’s climate. While short-lived compared to carbon dioxide, methane’s intense warming potential makes it a primary driver of global temperature rise. Emissions come from human activities such as agriculture, fossil fuel extraction, and waste management. Solutions ranging from feed additives in agriculture, leak detection in fossil fuel industries, and landfill gas capture in waste management offer concrete pathways to reducing methane output. Global cooperation and innovative strategies will be key to addressing this invisible yet dangerous threat to our climate.
