Why
Abrupt increases in aerosol concentrations can produce an initial rise in atmospheric warmth, despite their reflective properties that help move sunlight away from Earth's surface.
The Frontline Impact

How this affects you

This new understanding of aerosols' short-term warming effect before cooling could change how climate models forecast future climate impacts and how satellite observations are interpreted. The continuous changes in aerosol concentrations mean the atmosphere might never fully settle into a cooling phase, potentially altering estimates of pollution's climate impact.
