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

Physics > Atmospheric and Oceanic Physics [Submitted on 24 Jan 2026 (v1), last revised 29 May 2026 (this version, v3)] Title:Atmospheric Methane Removal as a Third Climate Intervention: Termination Risks and Air Pollutant Effects View PDFAbstract: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, the avoided warming by AMR is not durable due to methane's short atmospheric lifetime, although its temperature rebound upon termination is less abrupt than that of SRM. AMR's impact on tropospheric ozone can be further modulated by background pollutant levels.
