Greenhouse Effect and Global Warming
As the sun’s rays enter our atmosphere, the Earth’s surface absorbs light energy from the sun and emits it as heat energy.
About 31 % of the incoming radiation from the sun is reflected directly back to space by the earth's atmosphere.
Another 20 % is absorbed by the atmosphere. The rest of the incoming radiation is absorbed by the earth's oceans and land, where it is converted into heat, warming the surface of the earth and the air above it.
However, several gases in Earth’s atmosphere — such as carbon dioxide, methane and water vapor work like a blanket over the earth’s surface to retain much of this heat from escaping to outer space. That helps to warm our earth’s atmosphere. The gases do this by absorbing the heat and radiating it back to Earth’s surface. Such gases are called “greenhouse gases” because of their heat-trapping effect.
The phenomenon wherein the earth’s atmosphere trap the heat from the sun and retain it from escaping into outer space and increasing the earth’s surface temperature is called “Greenhouse effect”. Without this greenhouse effect, Earth would be too cold to support most forms of life.
Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide, methane , nitrous oxide and water vapor which trap radiated heat that would otherwise escape from Earth into the outer space.
Concept of Greenhouse
You might have seen in botanical garden plant growers growing plant in green houses.
Lets us try to understand the concept of growing plants in green houses.
The most basic greenhouse would be a simple transparent structure, preferably made up of glass or transparent plastic.
When the radiations of sunlight enter through the transparent walls of the greenhouse, it heats up the floor of the greenhouse.
The floor releases some of this thermal energy, which heats the layer of air at the bottom of the greenhouse.
Warmer air is lighter than cooler air, so the heated air rises to the top of the greenhouse. When the heated air rises, cooler air replaces it at the bottom of the greenhouse. This air becomes heated by the floor and also begins to rise.
This circulation of air helps keep greenhouse warmer than outside atmosphere.
Hence, greenhouses are useful for growing plants in cold climatic condition.

Learn the basics about the natural greenhouse effect.
The atmosphere helps to keep our planet warm by making it harder for the energy we get from the sun to escape back to the universe. Our atmosphere is held to the earth by the force of gravity.
Visible light gets straight through our transparent atmosphere and is partly absorbed by the earth which gets hot. Hot things radiate infra red rays. Although visible light got through the atmosphere, the infra red radiation coming from the earth finds it more difficult to get through. So the atmosphere acts a bit like glass letting visible light through to warm the earth but some of the heat (or infra-red) radiation now given off gets absorbed by certain gases in the atmosphere, called greenhouse gases.
In this way the earth is kept warm and we say there is a natural greenhouse effect. The two natural gases that absorb infra-red are water vapour and carbon dioxide. Clouds, made of water droplets, insulate night skies in the winter, but without the clouds the heat gets away and frost forms.
Before the world became industrialised by burning fossil fuels such as coal oil and natural gas, the carbon dioxide concentration in the atmosphere was about 0.028% tiny compared with O=O at 21% and NN at 78%, but enough to keep us warm. Without this natural blanket of insulating gas the earth would be too cold to support life as we know it.

Educational video for children to learn what the Greenhouse Effect is and how it works. The Earth is surrounded by the atmosphere, a thin gaseous layer which allows part of the solar radiation to penetrate. To do that, this layer contains gases called "greenhouse effect gases", whose mission is to absorb part of that, and maintain the temperature of the planet. One of the main greenhouse effect gases is CO2, also known as carbon dioxide. In this video, children will find out that the increase of these gases is harmful for the Earth and they will look at several examples related to the cause of this increase like the Industrial Revolution, traffic, electricity consumption, factory production, massive farming or wildfires. At the end of the video, children will be able to explore ways to prevent this situation from getting worse like recycling, using renewable energies, electric transportation or reducing the use of plastic containers.

The science behind our lovely, relatively constant temperature on Earth (at least compared to the Moon!)
Part of our unit on Earth Systems. Check it out here:
The greenhouse effect can be thought of a little bit like the blanket you cover yourself with at night to keep warm. Our planet has an atmosphere around it containing certain gases that trap heat energy helping to keep the planet warm. And, no matter what anyone tells you, the greenhouse effect is a very good thing. No scientist would ever challenge that statement. The greenhouse effect is an entirely natural process. It was taking place long before the first lump of coal was ever burnt or the first cow let one rip.
But what exactly is it and how does it work?
The explanation starts with energy waves, presented here on the electromagnetic spectrum. Radio waves, light, x-rays… they’re all basically the same thing. We often think of them as travelling in waves and the thing that makes them different from each other is the length of that wave. To understand the greenhouse effect we’re interested in infrared waves, a fancy term for heat waves, as well as visible light. Notice that infrared waves have a longer wavelength than light waves. That’s an important detail.
As you probably know, we get our energy from the Sun. The energy from the Sun reaching our planet is mostly in the form of light energy. We’ll call this shortwave radiation to keep things simple.
Some of that energy is absorbed by the planet’s surface, causing an increase in temperature. Energy that has been absorbed and warmed an object can be then be released, but it isn’t released as light energy. The energy is released, or re-emitted, to use the correct term, as infrared waves (heat, in other words). Remember that these heat waves have a longer wavelength than the light waves that first reached the surface. From here on in we’ll call these infrared waves long wave radiation.
Next, let’s look space. Space is cold. Its baseline temperature is about -270 degrees Celsius. Very cold indeed. Far too cold for life to exist. Fortunately, since our planet orbits close to the Sun (close in astronomical terms, that is) we are kept well above that temperature.
However, if the Earth were to absorb and re-emit energy the way I’ve already described, and all of that long wave radiation is allowed to leave the Earth system, the average temperature of the surface would be around -18 degrees Celcius. That’s better than the -270 of space, but still fairly cold. We know the Earth isn’t really that cold… so what are we missing? Enter the greenhouse effect.
Fortunately for us, specific gases in our atmosphere, gases such as carbon dioxide, methane and others, all known as greenhouse gases, are able to absorb and re-emit the long wave radiation coming from the surface of the Earth. Now remember, shortwave radiation reaches us from the Sun, but long wave radiation is radiated from the surface. These greenhouse gases are not able absorb short wave radiation reaching the Earth. Consequently, they let the Sun’s energy in, but then trap some of it as it tries to leave. This trapping of heat energy obviously raises the temperature in the atmosphere, Earth’s surface and it’s oceans.
So basically, our atmosphere traps some of the heat energy in the Earth system, keeping it that bit more warm. As a result of Earth’s natural greenhouse effect the average temperature on our planet is about 15 degrees Celsius, 33 degrees warmer than it would be without any greenhouse effect.

Correction to what I say at 7 mins 13: The major reason air pressure decreases is that the gravitational pressure from the air above it decreases. The gravitational force itself also decreases but that's a rather minor contribution. Sorry about that, a rather stupid brain-fart.
How does the greenhouse effect work? Greenhouse gases, such as carbon dioxide and methane, prevent infrared radiation from escaping to outer space. This warms the surface of earth. More greenhouse gas means more warming. Simple enough! Alas, if you look at the numbers, it turns out that most infrared radiation is absorbed almost immediately above the ground already at pre-industrial greenhouse gas levels. So how does it really work? In this video, I try to sort it out.
