Excess greenhouse gas emissions primarily result from human activities such as burning fossil fuels for energy, deforestation, and industrial processes. Transportation, agriculture, and waste management also contribute significantly to emissions. The combustion of coal, oil, and natural gas releases carbon dioxide, while methane is often emitted from livestock and landfills. These activities disrupt the natural balance of greenhouse gases in the atmosphere, leading to climate change.
It is called global warming because of greenhouse effect.and greenhouse effect happens when there is too much greenhouse gas in the atmosphere. Greenhouse gas is used for trapping some of the sun's heat for the earth's warmth.And when there are too much Greenhouse gas, all of the sun's heat gets trapped inside the earth, causing the earth's temperature to rise. Greenhouse effect is normally caused by human activities such as burning fossil fuels.
Carbon Dioxide is the greenhouse gas of most current concern. It is created by burning any fuel composed of hydrocarbons, such as wood, oil, gasoline, coal, etc. The reason it is of so much current concern is that the level of carbon dioxide (chemical formula CO2) in our air has gone from 280 ppm (parts per million) to almost 400 ppm. In the last 50 to 75 years we have burned about one-half of all the oil which earth accumulated over perhaps one-million years plus lots of coal, natural gas, and wood. A lot of the carbon dioxide was absorbed by the oceans and the earth, so the 400 ppm might go much higher. Methane is another greenhouse gas. It is created by people and animals. It increases as human population increases and as our food animal production increases. Nitrous oxide is yet another greenhouse gas. It is created by burning. The nitrogen comes from air. CFC-12 is a serious greenhouse gas, but its use has been largely phased out to protect our ozone layer. HCFC-22 is also serious, but it is being phased out to protect the ozone layer. Other greenhouse gases include nitrogen trifluoride, and sulfur hexafluoride. Water vapor is the main greenhouse gas. Greenhouse effect is not all bad. Without it earth would be too cold for us, but too much greenhouse can make our earth too hot.
Methane is a greenhouse gas that contributes to global warming by trapping heat in the Earth's atmosphere. It is more potent than carbon dioxide in terms of its warming impact, although it is present in smaller quantities. Methane is released into the atmosphere through natural processes like wetland decomposition as well as human activities such as livestock farming, landfills, and fossil fuel extraction.
Greenhouse gases are helpful because they trap heat in Earth's atmosphere, which keeps the planet warm enough to support life. Without greenhouse gases, Earth would be too cold for humans, plants, and animals to survive. However, an overabundance of greenhouse gases can lead to climate change and negative impacts on ecosystems.
Emissions means "what comes out", or "what is released".When we talk about greenhouse gas emissions we are usually referring to carbon dioxide, which is emitted when we burn fossil fuels. It can also refer to methane, another greenhouse gas, which is emitted from cattle and from melting tundra.its is emissions from cars , fridges, factory's it goes into the atmosphere and coats things such as tree's and they cut the trees down and then it is less oxygen
Just enough greenhouse gas keeps the planet warm enough for life. This has been happening for millions of years. Too much, as is happening now, is causing a global warming of the planet. Too little will mean that the planet, and we, will freeze.

A greenhouse gas is a gas (with at least three atoms) that traps heat inside the earth's atmosphere. Greenhouse gases include carbon dioxide and methane. It is important that some heat is trapped inside our atmosphere - otherwise the earth would freeze. But too much heat has a negative impact on the climate.
Ozone acts as a greenhouse gas too. It traps the heat emitted from the sun and does not allow it to exit.

Carbon dioxide has to be monitored as it is a greenhouse gas. Too much causes global warming. Too little will mean that the earth will cool, even freeze.
The earth's atmosphere is affected by solar energy because the energy creates a greenhouse effect. When the radiation of the sun makes the earth too warm, there will be too much greenhouse gas that gets trapped in the atmosphere.
The greenhouse effect needs:An atmosphere that contains greenhouse gases like carbon dioxide, methane, nitrous oxide etc.Heat from the sun (ultraviolet radiation) that warms the earth.Heat from the warm earth (infrared radiation) that rises into the atmosphere and is captured by the greenhouse gases.The greenhouse effect is a good thing. If we didn't have it the earth would be too cold for us to live on. The problem now is that we have added too much greenhouse gas, and the atmosphere is trapping too much heat causing global warming. This global warming causes climate change.
Infrared heat rises from the surface of the earth into the troposphere (the lowest level of the atmosphere). It is captured there by greenhouse gases, so the troposphere warms. This is called the greenhouse effect, and too much greenhouse gas means global warming.
Ozone is a greenhouse gas in nature too. It is a gas which absorbs heat when at lower levels.
Ozone is a green house gas. But other greenhouse gases do not absorb UV rays.
