also wonder why disastrous weather events like super-storm Sandy continue to increase in their frequency and severity? Many modern scientists attribute these dangerous environmental trends of global warming to the ‘greenhouse effect’. The ‘greenhouse effect’ results from greenhouse gases such as carbon dioxide rising into the atmosphere‚ trapping infrared radiation from the sun‚ and emitting ultraviolet radiation that can puncture the earth’s stratospheric ozone layer. A healthy ozone layer should

The Greenhouse Effect The greenhouse effect‚ in environmental science‚ is a popular term for the effect that certain variable constituents of the Earth’s lower atmosphere have on surface temperatures. These gases--water vapor (H2O)‚ carbon dioxide (CO2)‚ and methane (CH4)--keep ground temperatures at a global average of about 15 degrees C (60 degrees F). Without them the average would be below the freezing point of H20. The gases have this effect because as incoming solar radiation strikes

release substances into the air‚ some of which can cause problems for humans‚ plants‚ and animals. There are several main types of pollution and well-known effects of pollution which are commonly discussed. These include smog‚ acid rain‚ the greenhouse effect‚ and "holes" in the ozone layer. Each of these problems has serious implications for our health and well-being as well as for the whole environment. One type of air pollution is the release of particles into the air from burning fuel for

Greenhouse gases Carbon dioxide is a colourless‚ odourless gas that makes up .04 percent of the earth’s atmosphere. It’s released by the breakdown of organic materials‚ by animals when they respire‚ and by the burning of fossil fuels. Carbon dioxide isn’t toxic—after all‚ we exhale it with every breath and use it to make our drinks fizzy. However‚ carbon dioxide is considered a pollutant because‚ as a greenhouse (heat-trapping) gas‚ it’s a significant contributor to global warming. In the last 150

Case 1.2 Green Economics Taking account of environmental costs People have become concerned by a number of environmental problems in recent years. These include: The greenhouse effect. This is caused by carbon dioxide and other gases emitted again by power stations‚ various industries and cars. The fear is that these gases will cause a heating of the Earth’s atmosphere. This will lead to climatic changes which will affect food production. It will also lead to a raising of sea levels and flooding

æ Solutions Reducing use of fossil fuels would significantly reduce the amount of carbon dioxide produced‚ as well as reducing the levels of the pollutants which cause acid rain (Solutions). This can be achieved by either using less energy in general‚ or using alternative energy sources. There are many ways to conserve energy such as: turning off any lights in a room which isn¡¦t being occupied. If you¡¦re making a short trip to the store and it is in walking distance conserve energy and take

What are Greenhouse Gases? These are the gases that make up our atmosphere: Carbon Dioxide 89% Methane 7% Nitrous Oxide 3% Halocarbons 1% What is the Greenhouse Effect? The Greenhouse Effect is the way that gases in the atmosphere trap heat from the sun. They let heat in‚ but prevent most of it from escaping. It is essential for life because we need a certain amount of radiation to heat up our atmosphere. What human activities produce Greenhouse Gases? By burning fossil fuels such as coal‚ oil and

* What is the greenhouse effect‚ and how does it work? The greenhouse effect is when the short wave lengths of visible light from the son pass through a transparent medium. They are then absorbed but the longer wavelengths of the infrared re-radiation from the heated objects are unable to pass through that medium. The Greenhouse Effect is when there are various gases in the atmosphere‚ such as carbon dioxide and even water vapor that traps the sun ’s energy‚ or heat‚ inside. When unable
