Clean air policies are key for successfully mitigating Arctic warming

K. V. Salzen, C. H. Whaley, et al.

This groundbreaking research by Knut von Salzen and colleagues reveals that while clean air policies can significantly benefit human health, they may paradoxically exacerbate Arctic warming. The study underscores the urgent need for balanced strategies that target both climate change and air quality.

Abstract
This paper investigates the impact of clean air policies on Arctic warming using integrated climate and air quality modeling. It finds that while reductions in sulfur emissions offer significant human health benefits, they could paradoxically enhance Arctic warming. The study highlights the need for carefully designed emission reduction strategies that simultaneously address climate change and air quality, emphasizing the crucial role of reducing black carbon and methane emissions to mitigate Arctic warming.
