Better electricity sharing across states would dampen the effects of variable weather on wind and solar power

High in the sky, aerosols from airplane exhaust become encased in ice and form the bright contrails seen in a plane’s wake.

Age of Humans

Airplane Contrails May Be Creating Accidental Geoengineering

Dissipating haze from plane exhaust alters how sunlight reaches the Earth and may be unintentionally affecting our climate
