Explainer: How human-caused aerosols are ‘masking’ global warming (Carbon Brief)

First published at Carbon Brief by Zeke Hausfather on June 10, 2025 https://www.carbonbrief.org/explainer-how-human-caused-aerosols-are-masking-global-warming/ Human-caused emissions of aerosols – tiny, light‑scattering particles produced mainly by burning fossil fuels – have long acted as an invisible brake on global warming. This is largely because they absorb or reflect incoming sunlight and…
