How increasing ghgs throws the energy balance out of equilibrium and the process that occurs to reach a new equilibrium?
Greenhouse gas emissions' capacity to increase global warming and the energy balance of our current atmosphere by selectively absorbing infrared light, greenhouse gases trap energy in the atmosphere.
In general, the rate at which energy is radiated from the atmosphere to the surface is higher than the rate of incoming solar radiation.
Each greenhouse gas has a unique atmospheric lifetime and capacity to warm the planet.
Energy must be conserved; it can take on many forms, but the overall quantity must remain constant. Energy cannot be created or destroyed. The renowned conservation of energy principle is this.
The square of the mean speed of atoms and molecules is used to calculate temperature.
There are many distinct kinds of energy, yet they all need to be preserved.
The equilibrium between solar visible light absorption and infrared light emission governed the temperature of the early Earth (as well as other airless planets and satellites). The radiative equilibrium temperature is the temperature at which these energy sources and sinks may balance one another.
Some planets can warm over their individual radiative equilibrium temperatures thanks to the greenhouse effect. The impact is brought on by greenhouse gases in the atmosphere, including CO2, H2O, NO, etc.
