The greenhouse effect and the influence of human activity on it. The green house effect the greenhouse effect is a term that describes how natural gases. Greenhouse gases vary in their relative contributions to global warming. The potential of a greenhouse gas to cause greenhouse warming is expressed by global warming potential gwp. Atmospheric concentrations of several greenhouse gases ghgs, including carbon dioxide co2, methane ch4, and nitrous oxide. Global warming potential gwp is defined as the cumulative radiative forcing, both direct and indirect effects, over a specified time horizon resulting from the emission of a unit mass of gas related to some reference gas. Methane ch 4 is 2030 times more effective than co 2 in trapping heat. Carbon dioxide, a key greenhouse gas that drives global climate change, continues to rise every month. Carbon dioxide co 2 is an atmospheric constituent that plays several vital roles in the environment. Population growth is another factor in global warming because as more people use fossil fuels for heat, transportation and manufacturing the levels of greenhouse gases continues to increase. Get to know how greenhouse gases contribute to planet global warming and discover how to reduce greenhouse gas emissions thanks to renewable energies by now, you will know what the greenhouse effect is and how it contributes to causing the impacts of climate change.

However, if the greenhouse effect is too strong, earth gets warmer and warmer. Greenhouse gases and their relative effects especially carbon dioxide and water vapour. The average surface temperature of earth is maintained by a balance of various forms of solar and terrestrial radiation. Global greenhouse gas emissions by gas, 19902010 this figure shows worldwide emissions of carbon dioxide, methane, nitrous oxide, and several fluorinated gases from 1990 to 2010. Pdf this study discusses the greenhouse gas emissions which cause the global warming in the atmosphere. Global warming and climate change are hot topics in the news media and legitimate concerns for those educated on the topics. The wri report is entirely designed to blame developing countries for sharing the responsibility for global warming. However, the misnomer greenhouse effect has perpetuated, and there are a number of aspects of the effect. This effect is caused by increased levels of carbon dioxide, chlorofluorocarbons and other gases. Carbon dioxide accounting for about 76 percent of global. Too much carbon dioxide and other greenhouse gases in air can make the greenhouse effect stronger which would result to global warming. It is a major concern it warms the globe firstly, 3.
How do greenhouse gases contribute to global warming. These gases absorb heat energy emitted from earths surface and reradiate it back to the ground. In the context of contributions of different gases to atmospheric warming the concept of global warming potential gwp can be useful. It is responsible for about half of the atmospheric heat retained by trace gases and also for 50% of the greenhouse effect. Essay on global warming and the greenhouse effect bartleby.

Find out what greenhouse gases are, how they work, and the role they play in warming our atmosphere through global climate change. Relation between greenhouse gases and climate change. In this way, they contribute to the greenhouse effect. This occurs when the suns energy reaches the earth and its reflected back to space and the rest is absorbed. Gwp is a measure of how much energy a greenhouse gas would add to atmospheric warming. Global warming global warming causes of global warming. Global warming and greenhouse effect linkedin slideshare. Greenhouse gas emissions, global warming and climate change. As more farming occurs to feed millions of new people, more greenhouse gases. For each greenhouse gas, a global warming potential gwp has been calculated to reflect how long it remains in the atmosphere, on average, and how strongly it absorbs energy. Greenhouse gases absorbs infrared radiation balance of energy of planet gets damage and along with this, there will be a dissimilarity in. Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the greenhouse, but blocking earths heat from escaping into space. Generally, a physical property of the atmosphere of earth is referred by an expression called greenhouse effect.
Without the greenhouse effect the earths average global temperature would be much colder and life on earth as we know. Gwpf reports views expressed in the publications of the global. There are a range of greenhouse gases, which include methane, nitrous oxide, and a range of smaller concentration trace gases such as the socalled group of f gases. The greenhouse effect is a natural process that helps to maintain the temperature of earth. The greenhouse effect is the warming of climate that results when the atmosphere traps heat radiating from earth toward space. The greenhouse effect and its impacts on environment.
