Last month, the National Academies of Sciences, Engineering, and Medicine (NASEM) released a report on a relatively new field of research – atmospheric methane removal. Addressing methane is critically important in addressing climate change – methane is the second largest contributor to human-driven warming after carbon dioxide.
