Greenhouse Effect And Impact Causes Diagram Impacts Facts

Greenhouse Effect And Impact- The word greenhouse’ refers to a glasshouse, which is considered to grow tropical plants in cold areas and some specific plants in the tropical areas too. It allows penetration of short wave solar radiations and absorbs the long wave radiations emitted inside the greenhouse. It blocks the re-radiated solar radiations.

Greenhouse Effect: Causes, Impacts, Facts And Diagram

The word greenhouse’ refers to a glasshouse, which is considered to grow tropical plants in cold areas and some specific plants in the tropical areas too.

It allows penetration of short wave solar radiations and absorbs the long wave radiations emitted inside the greenhouse. It blocks the re-radiated solar radiations.

This to retain the heat required for plant growth. The same processes occur in nature also; short wave radiations reaching the earth’s surface are reflects back to the atmosphere in the from of long wave radiations.

Like glass, a few gases chiefly carbon dioxide, methane, nitrous oxide, ozone and chlorofluoro-carbons allow the Sun’s radiation to pass through them and strike the surface of the Earth.

But like the glass roof of a greenhouse, these gases prevent the resulting heat from escaping which is useful since life forms require warmth for living.

If more greenhouse gases are release into the atmosphere, more heat is retaine near the Earth’s surface. The net result is that the Earth warms up considerably.

Causes of Greenhouse Effect

Earth’s temperature is increasing every year. It has been predicts that in the coming decades, Earth’s mean temperature will increase substantially.

Greenhouse gases are produce both by industrial and biological processes, but while industrial emissions are fairly well document, knowledge of the production rates of greenhouse gases through biological processes and the factors regulating emissions is still inadequate.

The greenhouse contribution of carbon oxide is highest and is up to 50 per cent. The greenhouse role of carbon dioxide and trace gases must be consider seriously.

Impacts of Greenhouse Effect

Greenhouse gases are responsible for trapping the solar energy. These gases helped in raising the Earth’s mean temperature from-15ºC to today’s 15ºC.

Without the greenhouse effect our planet would not have been a habitable place. However, any further increase in the greenhouse gases would affect the global temperature drastically.

Greenhouse role of trace gases

Beside carbon dioxide, important trace gases, which contribute to the greenhouse effect, are methane, nitrous oxide, ozone and chlorofluorocarbons.

The greenhouse role of these gases is also significant, one molecule of chlorofluorocarbons can have the same greenhouse effect as the addition of 10³ molecules of carbons dioxide in the atmosphere would be created.

Role of carbon dioxide

Carbon dioxide concentration in the atmosphere is about 356ppm. Around the year 1880s, its concemtration is approximately 280ppm. There has been an increase of almost 25 per cent as compared to the pre-industrial times. Accurate measurement of global atmospheric carbon dioxide concentration is available only since 1958 but they indicate a marked increase in carbon dioxide concentration since then.

Facts of green house

The greenhouse effect is a natural warming process of the earth. When the sun’s energy reaches the earth some of it is reflects back to space and the rest is absorb. This effect makes the planet warmer, in the same way a greenhouse keeps its inside temperature warmer. The Greenhouse Effect is the physical mechanism of this blocking mechanism in our atmosphere that influence how much heat we retain within the atmosphere.
