The use of chemicals given off from different material objects such as cars and aerosol cans throw off the greenhouse effect. This is known as global warming. Global warming can effect numerous aspects of the environment including water resources, coastal resources, agriculture, forests, and energy consumption. Without it, the earth would stay at a constant temperature of 18 Celsius.
Use an editor to spell check essay. There are two more important hazards which are posing challenges to future existence of our civilization are Green House Effect and Ozone Depletion.
Radiant energy arrives through sunlight, which is remitted by the surface at infrared wave lengths as heat. Carbon dioxide and water vapor in the atmosphere absorb this infrared radiation and act as a blanket, with net effect atmospheric temperature rise.
In the Earth more deforestation and burning of fossil fuel enhances water vapor, carbon dioxide, ethane, so there is likely to be a gradual increase in the mean air temperature of several degrees, which may result in melting of polar ice and a rise in mean sea level.
The rise in sea level will have immediate impact on coastal life such as aquaculture, agriculture and forestry.
This may also result substantive loss of life, submergence of areas, destruction of property. The global process of industrialization has brought such a change in the situation.
This warming of Earth due to greenhouse effect is a challenge to human civilization. Ozone is a form of oxygen having molecules The gas Ozone is concentrated on the stratosphere.
It is produced by the action of ultraviolet light from the sun in the air. The ozone layer shields the Earth from harmful effects of solar ultra violet radiation, but can be decomposed by complex chemical reactions, notably involving chlorofluorocarbons CPAs.
Inthe Montreal Protocol was signed by around 40 countries to limit their use, with the intention that by worldwide consumption of CFCs should be 50 percent of levels. Reports that short-lived holes have been observed above the Arctic have led to renewed efforts in Europe to reach agreement on accelerated reduction in CFC consumption.
The Antarctica hole was estimated to be 28 mn sq. The Cambridge paperback encyclopedia. In India under Environment Protection Actit was decided that industries using ODS would be discouraged, commercial banks have instructed not to issue finance for industries those who would use ODS technologies.
Environmental protection became a key issue at Stockholm conference, in The United Nations Framework Convention on climate change UNFCCC aimed at stabilisation of greenhouse gas concentrations in the atmosphere at levels that would prevent dangerous anthropogenic interference with the climate system.
However, as per existing commitments, India is not required to adopt any restrictions and limitation of greenhouse gas emissions. But later protocol such as Kyoto conference called for joint efforts of developed and developing economies to cut greenhouse gas emissions.The greenhouse effect plays a crucial part in preserving the environment on earth.
The use of chemicals given off from different material objects such as cars and aerosol cans throw off the greenhouse effect. Essay # 2. Green House Effect and its Sources: Global warming is the result of ‘Green House Effects’ created by green house gases.
Sunlight warms the earth’s surface during day time and earth’s surface radiates heat back to the space. GREENHOUSE EFFECTS IntroductionThe greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is .
Global Warming and 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.
Greenhouse effect occurs due to human activities and many of countries are still finding the best way to solve the problem of greenhouse in this twenty-first century, even though greenhouse effect is a common incident for decreases. Apr 23, · Greenhouse Effect Essays (Examples) Filter results by: Essay Paper #: The greenhouse effect is a condition that occurs when the Earth's atmosphere captures radiation from the Sun.
Solar heat is trapped by certain gases (including carbon dioxide and methane). These gases allow sunlight in but not back out of the atmosphere.
