Greenhouse effect

The greenhouse effect is the process in which the emission of infrared radiation by the atmosphere warms a planet's surface. The name comes from an analogy with the warming of air inside a greenhouse compared to the air outside the greenhouse. The Earth's average surface temperature is about 33°C warmer than it would be without the greenhouse effect. The greenhouse effect was discovered by Joseph Fourier in 1829 and first investigated quantitatively by Svante Arrhenius in 1896. In addition to the Earth, Mars and especially Venus have greenhouse effects.The Earth receives energy from the Sun in the form of radiation. The Earth reflects about 30% of the incoming solar radiation. The remaining 70% is absorbed, warming the land, atmosphere and oceans. For the Earth's temperature to be in steady state so that the earth does not rapidly heat or cool, this absorbed solar radiation must be very nearly balanced by energy radiated back to space in the infrared wavelengths.

It is caused by the increasing of carbon dioxide, water vapour and methane that is caused by pollution. Carbon dioxide is released by human as they exhaled and also produced when open burning happened. It is human nature to exhale carbon dioxide. Carbon dioxide will increased the earth's temperature. However, greenery such as plants and trees produced oxygen which will balanced the earth's temperature and produced oxygen for human respiration. Unfortunately, nowadays deforestation is happening widely all over the world. Beside that, erosion also happened when there's no longer trees and root to support the soil from sliding.

Greenhouse effect will caused global warming. Climate change can negatively affect the earth's delicate ecosystems. Global warming has been linked to dyingcoral reefs, dangerous new weather patterns and the extinction of plant and animal species.

Many people refer to global warming as a crisis. It is a common misconception that there is nothing an individual can do to abate global warming. One of the best ways to prevent further increase of greenhouse gases is to reduce their emissions. Changing individual consumption patterns may be one of the most effective ways of doing this. Most energy in the Malaysia is produced by the burning of fossil fuels. By reducing our individual use of energy derived from fossil fuels, we can contribute to reduced emissions.Another method for reducing greenhouse gases is to increase their uptake by the environment. This can be done by stimulating the increase of photosynthetic production by primary producers. For this reason there has been a large movement to promote planting trees and restoring forests. However, because trees grow so slowly, this is not a highly effective method of abatement. Therefore scientists are also investigating ways to stimulate phytoplankton growth in the oceans.
