Short summary

Removing the greenhouse gas methane from the atmosphere is being considered as an interim climate change solution. This includes increasing its chemical removal via oxidation. I simulate proposed methods in a computer model of the atmosphere. Results show that some approaches are unable to decrease methane on a global scale, while all increase particulate matter air pollution. There are climate and health tradeoffs of atmospheric oxidation enhancement of methane.
