The greenhouse effect is an effect on the atmosphere as a result of the presence of a certain gases called greenhouse gases which are made up of carbon dioxide‚ chlorofluorocarbons‚ methane‚ nitrous oxide‚ low-level ozone and water vapour. Greenhouse gases in the atmosphere are similar to the greenhouse glass panes which trap the heat and warm the greenhouse. When the greenhouse effect occurs‚ sunlight enters the Earth’s atmosphere and while some solar radiation is reflected back to space

environment. Global Climate Change Proposal Scientists refer to global climate change as any alteration in the average temperature involving the climate system. The climate system involves the following: our atmosphere‚ including temperature‚ clouds and wind‚ precipitation‚ humidity‚ atmosphere trace gas and aerosol distribution; oceans; volcanoes; land; cryosphere‚ which includes ice cover and snow cover; and the sun (Murck‚ Skinner‚ & Mackenzie‚ 2010). The alternations have been increasing more

others. These all have unique solutions which are now being promoted by environmentalists. Certain laws and treaties are aimed at reducing the emission of pollutants that result in global warming. In 1988‚ the International Conference on the Changing Atmosphere drew scientists and decision makers from 48 countries. Some policies could successfully reduce global warming. Raising fossil fuel prices‚ taxing emissions‚ and encouraging people to take environmentally friendly action through such activities as

For example‚ Rushkoff says in the reading that Malls are designed according to atmospherics‚ such as their temperature and lighting. These are all designed to create a consuming atmosphere.

also to our atmosphere. We have different kinds or types of pollution; we have pollution in land‚ in water and in air. We all know that these came from pollutants which were produced by human. Some of these are wood burning to produce charcoal‚ vehicular activities‚ improper disposal of waste‚ forest fires or wild fires‚ and other activities producing unnecessary gases. We all know that these are harmful for us‚ but what would be the effect of these gases as it goes up in the atmosphere? Would it be

climate include the sun‚ volcanic eruptions‚ and Earth’s orbit. But how exactly does something like a volcanic eruption effect climate? This is because “Explosive volcanic eruptions modify the composition of the atmosphere by injecting small particles called aerosols into the atmosphere layer.” These released aerosols block the solar radiation that would have reached Earth’s surface and consequently‚ it has cooling effect on Earth’s surface.

The solar system consists of the Sun and 9 planets revolving around it in different orbits. The statistics of the sun and the planets are given below : SUN Age : About 5 Billion years Distance : 149.8 Million Kms Diameter : 1‚38‚400 Kms. Photosphere temperature : 5‚770 K Core temperature : 150‚000‚000 K Absolute visual magnitude : 4.75 Rotation (as seen from the earth at the equator) : 25.38 days Rotation (near the poles) : 33 days The sun consists of 71% of Hydrogen‚ 26.5% Helium and

We are putting greenhouse gases such as carbon dioxide‚ into the atmosphere. Sulphur dioxide is another harmful gas that comes from power stations and vehicles. It is very acidic‚ which means it eats

threats. The problem lies in the disruption of the balance between how much carbon dioxide plants intake‚ and what our population produces. If this natural filtering process is unbalanced‚ the atmosphere will receive too much carbon dioxide and other greenhouse gases. Once these gases form in the atmosphere‚ they act as barriers trapping in heat and warming the earth. This process is not new. In fact‚ without the greenhouse effect‚ the average surface temperature of the earth would be about 59 Fahrenheit
