Wildfires: Smoke and cloud interactions unexpectedly result in cooling

For years, scientists determined that smoke, overall, diminishes clouds’ cooling effect by absorbing light that the clouds beneath the aerosols would otherwise reflect. This new study does not dispute that phenomenon. However, more dominantly, the new study found that smoke and cloud layers are closer to each other than previously thought. This makes the clouds more reflective of light and, thus, accelerates the clouds’ cooling effect.
