The greenhouse effect occurs when certain gases in the Earth's atmosphere, like carbon dioxide and methane, trap longwave radiation (heat) from the sun. These gases allow sunlight to pass through and warm the Earth's surface, but they prevent some of the heat from escaping back into space. This trapped heat warms the planet, similar to how a greenhouse traps heat to keep plants warm.
Longwave radiation refers to infrared radiation emitted by the Earth's surface and atmosphere, which can be absorbed by greenhouse gases and contribute to warming the atmosphere. Shortwave radiation, such as sunlight, is absorbed by the Earth's surface and then re-emitted as longwave radiation. This difference in wavelengths affects how energy is distributed in the atmosphere, with longwave radiation playing a key role in the greenhouse effect and shortwave radiation driving the Earth's climate system.
Shortwave radiation comes from the sun and is absorbed by the Earth's surface, warming it. Longwave radiation is emitted by the Earth's surface and is absorbed by greenhouse gases in the atmosphere, trapping heat and warming the planet. These differences in radiation play a crucial role in regulating the Earth's temperature and climate.
The energy exchange between space, the atmosphere, and Earth's surface produces a balance of incoming solar radiation and outgoing thermal radiation. Solar energy is absorbed by the Earth's surface, which then emits thermal radiation back into the atmosphere. Greenhouse gases in the atmosphere trap some of this thermal radiation, leading to the warming of the Earth's surface.
Insolation (incoming solar radiation) heats the Earth's surface, causing it to warm up. The warm surface then emits terrestrial radiation (heat energy) back into the atmosphere. Greenhouse gases in the atmosphere trap some of this terrestrial radiation, leading to an increase in temperature, known as the greenhouse effect.
The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat from sunlight, causing the planet to warm up. Sunlight enters the Earth's atmosphere and some of it is absorbed by the surface, which then emits infrared radiation. Greenhouse gases like carbon dioxide and methane trap this radiation, preventing it from escaping into space and leading to a warming effect on the planet.

Methane is a greenhouse gas and it absorbs infrared radiation that is remitted from the earth. As it absorbs the radiation it is stopping it from being re-radiated to space thus warming the earth.
Wein's Displacement Law explains the difference between long and shortwave radiation. Shortwave radiation has shorter, more high energy wavelengths (stronger with less distance to travel) while longwave radiation travels farther, but has less energy. Earth's radiation is 20 times longer than the maximum solar radiation, so it is referred to as longwave, while solar energy is referred to as shortwave radiation.
The primary wavelengths of radiation emitted by Earth's surface are in the thermal infrared range between 8 and 14 micrometers. This radiation is also known as longwave radiation and is a key component of Earth's energy balance.
Net radiation is the difference between incoming solar radiation absorbed by the Earth's surface and outgoing longwave radiation emitted back into space. It represents the overall energy balance at the Earth's surface, determining whether the surface gains or loses heat.

The greenhouse effect is a natural phenomenon where gases in Earth's atmosphere trap heat from the sun, warming the planet. A black body is an idealized object that absorbs all radiation incident upon it. Wien's Law describes the relationship between the temperature of a black body radiator and the wavelength at which it emits the most radiation. In the context of the greenhouse effect, Wien's Law helps explain how gases in the atmosphere absorb and emit thermal radiation, contributing to the overall warming of the Earth.
Greenhouse gases contribute to global warming by trapping heat in the atmosphere. This warming can lead to ozone depletion by increasing the breakdown of ozone molecules. Ozone depletion, in turn, can exacerbate global warming by allowing more harmful UV radiation to reach the Earth's surface.
