Guy R. McPherson, Beril Kallfelz Sirmacek, William M. Kallfelz

TL;DR
This paper discusses how aerosol masking, which cools the planet, complicates climate mitigation efforts and proposes ethical and policy strategies to address this overlooked challenge.
Contribution
It highlights the significance of aerosol masking in climate change and advocates for new ethical and policy approaches to effectively mitigate its effects.
Findings
Aerosol masking significantly impacts global temperature trends.
Current mitigation strategies often ignore aerosol masking effects.
Proposed policies aim to incorporate aerosol effects into climate action.
Abstract
The aerosol masking effect, or global dimming, is a well-documented instance of our ongoing climate predicament: Efforts to mitigate greenhouse gas production by curbing industrial activity or transitioning to clean sources such as solar or nuclear inevitably and inadvertently accelerate planetary warming. This undesired outcome results from aerosols that result from industrial activity. This article describes some climate mitigation strategies destined to fail because they do not account for the aerosol masking effect. Moreover, many political and ethical initiatives emphasize the business as usual framework, thus worsening the conundrum. We suggest instead a set of ethical and policy initiatives to address the challenge of aerosol masking, and we describe how our contemporary predicament can be ameliorated in the face of these significant and often-overlooked challenges.
