Factors such as an increase in greenhouse gas concentrations, particularly carbon dioxide and water vapor, lead to more infrared radiation being trapped in the Earth's atmosphere. This phenomenon, known as the greenhouse effect, contributes to global warming and climate change. Other factors that can enhance the retention of infrared radiation include deforestation and urbanization.
This phenomenon is known as the greenhouse effect. Excess carbon gases trap heat in the Earth's atmosphere, leading to a warming trend that contributes to climate change.
1. Most of the short wave energy produced by the sun passes easily through the atmosphere and heats the surface of the earth. 2. The earth's surface then returns long- wave energy into the atmosphere. but this energy cannot easily pass out through the gases of the atmosphere. So some heat is retained in the atmosphere. 3. this is sometimes called the greenhouse effect because the glass of a greenhouse, like the atmosphere allows solar energy to pass through it and traps some of the energy inside.
Greenhouse gases absorb and retain the heat rising from the earth. As greenhouse gases are increasing, so is the temperature of the earth. This is causing global warming and climate change.This heat is released during the cooler periods of the day which, in turn allow life to exist on the planet. The heat is not indefinitely retained, but part of the natural process.
Carbon dioxide (and other gases) creates a "blanket" around the earth trapping heat in the atmosphere. If these "greenhouse" gases were not there some of the heat would escape from the earth's atmosphere --------------------------------------------------------------------------------------- Carbon dioxide is transparent to visible light but opaque to infrared light (i.e. heat). When sunlight passes through the atmosphere and heats the surface of the earth the earth radiates infrared light. At low levels of carbon dioxide most of this infrared escapes to space, cooling the earth; but at high levels of carbon dioxide most of this infrared is reflected back down to the surface of the earth, keeping it hot.
The atmosphere, oceans, ice caps, and land surfaces all play a role in determining the amount of heat retained by the Earth. Human activities, such as burning fossil fuels and deforestation, also contribute to the greenhouse effect, which traps heat in the Earth's atmosphere.

the greenhouse affect
Any greenhouse effect (including the one that takes place in an actual greenhouse) is a process by which the energy of sunlight is retained more than it otherwise would be. It's all about sunlight.
The ground is heated by the sun's rays penetrating the Earth's atmosphere and warming the surface. The heat is absorbed by the ground and retained, which contributes to the overall temperature of the Earth's surface.
The amount of energy the atmosphere absorbs depends on its composition, including greenhouse gas concentrations like carbon dioxide and water vapor, as well as aerosols and clouds. These factors determine how much incoming solar radiation is absorbed and retained by the atmosphere.

The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth's gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation).
the greenhouse effect
Greenhouse gases absorb and retain the heat rising from the earth. As greenhouse gases are increasing, so is the temperature of the earth. This is causing global warming and climate change.This heat is released during the cooler periods of the day which, in turn allow life to exist on the planet. The heat is not indefinitely retained, but part of the natural process.
Carbon dioxide acts as a greenhouse gas and retains heat radiation from the sun, which, combined with other greenhouse gases helps to maintain the earths surface temperature. Without the presence of CO2 in the atmosphere, most of the solar radiation would not be retained and thus the surface temperature would be very low and unable to sustain human life.
The balance of incident Solar radiation as compared to the Re-Radiation of the same incident Solar radiation is skewed so that the Re-Radiation is cancelled and the Heat - easily in infra-red form - is Retained at and by the Earth.
The situation for carbon dioxide is different from the situation for water. If we add CO2 to our atmosphere it will make it harder to lose heat (infrared radiation) back to space so it would probably increase the equalibrium temperature of the Earth. This is because the Sun pumps energy onto the Earth in the form of visible light photons. These photons heat the objects which absorb the visible light. These objects in turn radiate infrared radiation. The more infrared light gets absorbed in the atmosphere, the less gets radiated back to space, causing the energy to be retained, hence the temperature rises.Water is more complicated because it dependes on whether the water vapor is invisible or in a visible form like a cloud.Water vapor in the atmosphere in a transpearent way is just like CO2, it absorbs infrared light. However, water in the form of pools on the ground, ice, snow, or clouds, reflect a large percentage of the sunlight shining on them directly back to space (something like 20% to 90%). So it is impossible to say, without more study, whether adding water to the atmosphere will make it hotter by blocking infrared light or cooler by reflecting more of the Sun's energy away.An additional concern is that night time clouds can act as an insulating layer, not allowing daytime heat to be radiated into space. The balance between the increased albedo of daytime cloud cover and the increased insulation provided by nighttime clouds in not fully understood.
