Global warming is the result of the increase in the temperature of the earth above that from the natural green-house effect due to the addition of anthropogenically emitted green-house gases and particulate black carbon to the air. Global warming is increase of the average world temperatures as a result of what is known as the greenhouse effect. Certain gases in the atmosphere behave like glass in a greenhouse, permitting sunlight through to heat the earth's surface but trapping heat as it radiates back into the space. As the greenhouse gases build up in the atmosphere the earth gets hotter and hotter. The term "global warming" is a particular case of the more general term the climate change (which can also refer to the global cooling, such as occurs during ice ages). In principle, global warming is neutral as to the causes, but in common usage, it in general implies a human influence. A few organizations use the term anthropogenic climate change for the human-induced changes. An increase in the global temperatures can in turn cause other changes, together with a rising sea level and changes in the quantity and pattern of precipitation. These changes may boost the frequency and the intensity of extreme weather events, like floods, droughts, heat waves, hurricanes, and tornados.

The greenhouse effect discussion is correct but needs a little more clarification. The temperature of the planet is largely controlled by the sun and as it cools or heats up so does earth as well as Mars and Venus. The gas highest in percentage that holds in temperature is water vapor (95%). Therefore, the cause of Global Warming is unknown. Manmade greenhouse gases equals only .278%, the rest is natural.

Global warming is a name used to explain a steady but regular raise in the earth's average ground and temperatures of the whole planet earth. The measurements made by the scientists show that the worldwide temperature has raised up by about 1 degree Fahrenheit in the last century.
Global warming does not occur by default. It is purely a man-made dilemma. Each bit of coal, every liter of oil or gas that we humans burn up adds to the pack of gases in the atmosphere that surround the Earth like an ever thickening blanket. This is why the Scientists suppose that an increase in carbon dioxide emissions will steer the situation to further global warming.
We are already experiencing the effects of Global Warming and the changes occurring because of it. We can see the Glaciers are melting, plants and animals are dying, and the figure of harsh hurricanes and droughts are increasing like never before. If the global warming continues, we can imagine even more terrible results.
We can resolve this dilemma. In fact, we have an ethical responsibility to do so. Just some small changes to our daily schedules can add big differences in helping to discontinue global warming. This is the time to join together for solving this problem.

Global Warming The word was created in a Exxon board meeting as a advertising slogan and has been the worlds number one ad slogan ever. Just look at their profit s lately they made more money then any company ever. When G.W. Bush was running for election the first time one of the under lying issues was the public wanted to stop funding N.A.S.A. and make then get their own money. So they lied about the earths temps. by 3 degrees. over the past ten years they were able to alter the publics thinking about the planet and were caught in their lie in 2007 look it up if you don't believe me. It was in all the major papers the 3 degree difference now makes the past ten years the coolest since recorded time of temperature. Also all the temp. readings taken around America can't be counted as reliable the 2100 sites were found to be extremely flawed in where they put the thermometers beside heat pump exhaust units and such it was discovered by a meteorologists in L.A. and it also is in the papers. The ice caps that are melting in the arctic are not what they say, it is a natural weather recurrence that happens every 78 years and is well documented by the scientist. although they lie about the fact because (GLOBAL WARMING) has opened up a whole new way for them to get research grants from the government that they never could get before they used to have to beg borrow and steal to get grant money to study kooky stuff just wasting tax payers money , now they are king of the heap, global warming, global warming," the sky is falling", oh my gosh what are we going to do. don't believe all the crud the media blows at you, yes we are destroying our planet and I am the first to do things to make it a better place, but all the people who believe that we are on a short time limit to doom are not well informed. They are only hearing what they want to hear and are being sold on emotional sound bites by people selling them products for 5 times what they are worth but they will pay for these products because they are being sold on emotion the strongest sell tool ever designed by ad men. Every fact that I have written can be verified as a fact and if you are a person who can think with a open minded approach to issues then you will find out that there are many more scientist out there saying that this whole global warming thing is a big fat LIE used by the politicians and big corporations to do two things 1: sell you products, 2: persuade you to give them money and to vote for them. National geographic is the "biggest lier of them all," they have resorted to just making stuff up, editing pictures and video to make it look like the world is coming to an end. Just to sell magazines and a tv show that 12 years ago was about to go bankrupt . "that is as shameful as it gets. If you haven't noticed anytime you hear about the word "GLOBAL WARMING" its right at the point where they are going to sell you something. Take AL Gores movie for example A judge made the entire school system rerun the movie and made the teacher stop the movie and point out the lies as they went through it and there were like 37 lies down right lies. ITS ALL ABOUT MONEY as long as they got your heart strings they got your wallets. ever noticed none of the technology you hear them talk about is being used in any meaningful way to society. The eco- cars only get about half the gas mileage they claim they do. solar panels are useless to a residential home for any type of real need of energy. And if you drive a car then you have no place to say anything to anyone about being green because your not at all. They want the public to live green while they live in mansions, fly private jets and ride in limos using the money they made off of you selling you their earth friendly products at 6x times the real value. In 1995 paper salesmen were trying to sell me recycled cups for 1 cent a peace and new ones were 6 cents a peace they couldn't give them away at the time there was no recycling it wasn't heard of it the time. now the same (RECYCLED) cup is 36 cents per cup if that ain't proof then your lights are on dim and ain't going to ever be fully lit. We need to stop killing our planet but we as single people need to open our eyes to the truth about this issue. When I was in the 7th grade a man came to our school and talked about how in the year 2005 new Orleans would be forever under water due to global warming and the sea rising. well its 2008 it N.O. is still there. there is nothing we could ever do to kill this planet we don't have the power and never will only god can do such a thing and he put this planet here and its resources for humans to use. its here for us, but we need to take care of it.
One of the most concerned topics of this century is Global warming and is a subject to be talked about as it has severe after-effects. We all noticed how in the past few years the intensity of heat has increased in our planet. This is an effect of Global warming. Global warming, as the word suggests, is a measured increase in the overall temperature of the planet. Over the years, the temperature of the planet has become hotter than before and all this is basically caused by human activity. Examples of such activities are industrial, farming, deforestation and burning of fossil fuels (oil and petroleum) which gradually increases the presence of carbon dioxide and methane in the Earth's atmosphere. These gases trap the heat in the atmosphere, hence if there is an increase in human activity causing these gases to grow, there will be more heat trapped in the Earth's atmosphere, eventually creating hotter climates. Electrical pollution causes global warming and electricity is produced by the burning of fossil fuels. So the more electricity we use, the more it causes an increase in the global warming. Due to the increase in heat, there are other natural disasters that have hyped up in the past few years due to global warming. More earthquakes, hurricanes, storms etc have occurred, which were not that successive previously. Hence, there has been an increase in diseases as well thus causing human loss.

This comes straight from "NOVA"! Carbons are ONE of the main causes of the problem! And MOST of the carbons come from the use of fossil fuels, and if you could INSTANTLY, at the snap of your fingers stop ALL fossil fuels, then it would take 50 years before you could stop what is already there! And do nothing for the other things that are a factor!
So that means there is no one magic thing anyone can do!
However as my Mother said,"Son, do you know what the dog said when he pissed in the ocean?" And I no Mam. Well he said," Every little bit helps!"
I don't give up or quite! How about you?

The term global warming refers to Earth's slowly rising temperature, especially in the last 20 years or so. A major cause of global warming is air pollution from both cars and factories.
Not all scientists agree that global warming is happening. Some say it is impossible to know if the climate is changing overall. After all, temperatures vary from day to day and year to year. Most scientists, however, say the trend is up. The warmest days are warmer, the coldest days not as cold. They point out that the ten warmest years of the last century happened after 1980. The three hottest came after 1990. The hottest year on record was 1998.
These scientists say the Earth has warmed up about 1° Fahrenheit (0.6° Celsius) in the last 100 years. The rate of change, they say, is speeding up. A hundred years from now, the Earth may well be as much as ten degrees hotter!
Sunlight brings energy to the Earth. This light turns to heat when it hits the ground. The heat in turn seeps away from the Earth, but the atmosphere slows the heat's escape. The atmosphere is a layer of air around the planet. It holds in some of the warmth.
The atmosphere is a mixture of many gases. In the last 250 years, this mixture has been changing. The amounts of gases such as methane and carbon dioxide have been rising. These gases trap heat more effectively than other gases. They make the Earth's atmosphere act like the glass in a greenhouse. It lets sunlight in, but it doesn't let heat out. As a result, heat is building up close to the surface.

Global warming is the whole of ice in Icy areas melting away. Like in Antarctica there is a LOT of ice. But eventually it will all be turned into water. This causes the polar bears, penguins and many more mammals like thisdie because they will have no ice. Global warming is caused by pollution and the greenhouse and ozone layer. These things are also caused by pollution. You could help this by walking places, recycling, looking after the wildlife and many more. Hope this has helped.

Lot's of answers but nobody hit on this topic. I believe it is not global warming, it is GLOBAL CHANGE. The earth moves in cycles and as you may be aware, we went through a cycle know as the ice age where everything was frozen. Slowly, things began to warm and become what it is today. The earth continues to warm until there is something that will cause catastrophic storms and we will once again be in an ice age. My thought is that a majority of the land mass will be covered by water and the fault lines will split causing major volcanos, the ash and smoke from the volcanos will cause huge storms over most of the world. These storms will be the leading factor in refreezing the earth. Then we will go back and begin to warm again.

Global warming is when the polar ice caps melts from pollution like carbon dioxide. You can help reduce it by using energy saving things and solar powered things. There are hybrids that are partially gas and electric. So check it out and save the earth. Peace Out!

You should read comment made by Kongfish, he's got more facts right than they ever give you in the media
The earth's weather changes in broad cycles, but ice cores have shown that at no time in the last 650,000 years has the concentration of atmospheric carbon dioxide exceeded 300 parts per million (Google "RealClimate » 650000 years of greenhouse gas concentrations").
Our troposphere is currently approaching 380ppm (Click here for more info). It has been climbing there steadily since the Industrial Revolution, when man's need for energy increased dramatically and fossil fuels started to be burned with a vengeance.
Isotopic analysis of atmospheric CO2 shows that the source of this rise in CO2 does indeed fit emissions from fossil fuels (Click here for more info).
The reason this spells trouble is that CO2, and other greenhouse gases, are excellent absorbers of infra-red (a.k.a. HEAT) energy. Their increasing presence in the atmosphere cannot help but impact climate globally.
This is the nature, and the cause, of 'Global Warming'.
