If the sun’s total energy output for one second was stored in some super duper battery, it would take the US over 9 million years to use it all.

Adiabatic Lapse Rates…Adiabatic Lapse Rates…Adiabatic Lapse Rates…Adiabatic Lapse Rates…Through the troposphere, temperature drops with elevation at a normal lapse rate of 6.4 per 1000 m or 3.5 per 1000 feet on average.
The rate of change can vary substantially because of local weather changes

With pollution unable to mix in the upper atmosphere during an inversion, this leads to poor visibility and heath issues
