It's a way to measure the potential of greenhouse gases to warm the atmosphere relative to carbon dioxide.
GWP compares the amount of heat trapped by an amount of the greenhouse gas with the same amount of Carbon Dioxide (CO2). GWP is calculated over a period of years, usually 20, 100 or 500 years. The GWP of CO2 is standardised as 1.
Methane (CH4) is calculated as having an GWP of 86 over 20 years, and 34 over 100 years (much more powerful than CO2).
The GWP of a greenhouse gas depends on:
- how much heat it can hold (the absorption of infrared radiation)
- in what part of the light spectrum does it work best (the spectral location of its absorbing wavelength)
- how long it stays in the atmosphere (its atmospheric lifetime).

Is it 'global warming' or 'global warning'?
Global Warming.
Why does global warming decrease temperatures?
True global warming does not decrease temperatures. So, either the model for global warming's effects is hokus-pokus, or global warming as presently claimed, does not exist. Some global warming followers will have you believe that global warming makes the weather "act crazy". If true, then it is not really global warming, is it.
Is global warming a pollution?
Global warming in itself isn't pollution - global warming is the gradual warming of the earth. However, global warming was caused by carbon dioxide pollution in the atmosphere, but global warming in itself isn't a pollution. yes it is a pollution
What are misconceptions about global warming?
Global warming is not important.Global warming isn't happening.Global warming is happening but it's not our fault.Global warming is happening but we can't do anything about it.Scientists are not sure about global warming.
How is global warming affecting the air?
Global warming is warming the air. It is also warming the land and the oceans.
Which gas is used as reference to calculate global warming potential?
Carbon Dioxide (CO2) is given a Global Warming Potential measure of 1.There are many green house gases that cause global warming but the gas used as reference to calculate global warming potential is carbon dioxide (Co2)
What is the Global Warming Potential for ozone?
Ozone depletion can cause global warming. It is due to the plankton death.
What potential problem do you foresee?
I foresee global warming.
Why is global warming a potential problem to human life?
global warming causes higher sea levels which may cause floods in low lying countries :O
What does 'Against man-made Global Warming' mean?
If you were asked to speak in a debate, "Against man-made Global Warming" you would be arguing that man is not causing Global Warming. You would have to argue that Global Warming is occurring naturally.
Why worry about global warming?
We should be worry of global warming because it may mean to be the end of our planet -- the end of us.
Was Al Gore wrong about global warming?
No. Although Al Gore himself is not a scientist, he has listened carefully to what scientists have to say about global warming. He is concerned about scientific predictions about the potential effects of global warming on society and the world as a whole, because that is what most scientists are telling him.
Is it 'global warming' or 'global warning'?
Global Warming.
What are 2 words that means a potential impact of burning coal?
Global Warming or Climate Change.
Which of the following global issues dose the 1997 Kyoto protocol address?
global warming!!!!!!
Type of warming mean that shows the trend in increasing temperature of earth?
Global warming or global climate change is a type of warming that shows the trend in the increasing temperature of Earth.
Why does global warming decrease temperatures?
