Atmospheric Methane Removal as a Third Climate Intervention: Termination Risks and Air Pollutant Effects

Katsumasa Tanaka, Weiwei Xiong, Didier A. Hauglustaine +8

Atmospheric Methane Removal (AMR) is a third class of climate intervention, along with Carbon Dioxide Removal (CDR) and Solar Radiation Management (SRM). We show that, unlike CDR,…
