Anthropogenic Sources of Methane. What Stinks?

Carbon dioxide (CO2) is the predominant greenhouse gas released into the atmosphere by human activities.1 For instance, in 2019, carbon dioxide made up slightly more than 80% of all greenhouse gasses emitted into the atmosphere by humans in the United States.1,2 This makes carbon dioxide the main driver of global warming. However, there is another potent greenhouse gas released anthropogenically that’s accelerating global warming: methane (CH4).2 Why are Methane Emissions Harmful? As a greenhouse gas, methane traps heat in the Earth’s atmosphere, exacerbating human-caused climate change. Unlike carbon dioxide, though, methane traps 25 times more heat on a pound-per-pound basis… Continue reading Anthropogenic Sources of Methane. What Stinks?
