Impact of Coronavirus On Global Dimming

Magnitude of Global Dimming from Coronavirus Shutdowns: Part 1 of 3 // Mar 22, 2020

Global Dimming from industrial and transportation aerosols is likely between 0.25C and 1.1C with a best estimate of 0.5C. As global industry/transportation shutters due to our coronavirus actions, the sky clears due to reduced pollution, unmasking global dimming.

My educated best guess on the size of the direct effect warming pulse is 0.25C globally if half of industry shuts down, realized as a 0.5C warning over land and 0.125C warming over the oceans. Maybe double these numbers with indirect effects from cloud changes. Also, daily temperature range will increase, specifically due to shutdown of the airline industry.
