The pandemic has resulted in a massive drop in world-wide energy consumption. Since most energy use releases carbon dioxide into the atmosphere, this slowing of CO2 is a good thing. It won’t reverse the warming but will slow future warming by a tiny amount. On the other hand, airlines have grounded much of their fleet. It is well known that airplane contrails increase the reflectivity of the earth and thus have a cooling effect.
