Energy from the sun radiates down to Earth warming it up. The majority of the light is absorbed by land and bodies of water but some light is reflected back up into space. This energy is then converted to infrared radiation and goes back up into the atmosphere, but before it all can escape, some is trapped by greenhouse gases.
Here is an image explaining it further.
Who are the key players? The most prevalent greenhouse gas in the atmosphere is water vapor. Trailing just behind water vapor is carbon dioxide, then methane, nitrous oxide, and finally ozone. There are also many other gases involved in the greenhouse effect.
The greenhouse effect is contributing to global warming. Clouds, believe it or not, can relate to climate change. Clouds reflect and absorb infrared light and therefore warm and cool the Earth. A change in clouds, like their size or location would affect how they cool or warm the Earth.
The levels of carbon dioxide in the atmosphere have gone up 40% since the beginning od the industrial revolution or the late 1700’s. The CO2 levels are increasing because of humans activities such as burning fossil fuels and deforesting. As a result, many man-made chemicals have been released into the atmosphere and are contributing to global warming. These include, chlorofluorocarbons (CFCs), hydro chlorofluorocarbons (HCFCs), hydro fluorocarbons (HFCs), and perfluorocarbons (PFCs).
This video will sum up what I have talked about.

TheGreenhouseEffectBy Devin Carver
What is it? Energy from the sun radiates down to Earth & majority is absorbed by land + water Earth heats up and changes energy to infrared radiation. This goes back up into space, but some is trapped by the greenhouse gases The light trapped by the greenhouse gases heats up Earth even further
Who are the Key Players? The Greenhouse Gases WATER VAPOR Carbon Dioxide(CO2) Methane(CH4) Nitrous Oxide(N2O) Ozone (O3)
Climate Change Greenhouse Effect is changing our environment through global warming Higher temperature = more droughts Melting ice caps Rising sea level Clouds Clouds reflect and absorb infrared light and therefore warm and cool Earth A change in clouds changes how clouds cool or warm Earth
Humans Role in GreenhouseEffect/Global Warming CO2 levels increased 40% since late 1700’s CO2 levels are increasing in atmosphere by Burning fossil fuels Clearing forests Etc. Human-Made chemicals in atmosphere chlorofluorocarbons (CFCs) hydro chlorofluorocarbons (HCFCs) hydro fluorocarbons (HFCs) perfluorocarbons (PFCs)
