Many happenings in the earth are a vicious cycle. The absorption-emission-radiation cycle of the greenhouse gases has to be understood in depth. There are certain gases that cause the greenhouse effect. These are basically methane, carbon dioxide, water vapor, ozone and nitrous oxide. These gases are utilized by scientists to help grow plants as they radiate well and do not allow heat to escape. Downside of the same result is that the gases are causing the excess heat on the earth’s surface.
The use of refrigerators, air conditioners and other cooling systems emit the greenhouse gases to a large extent. Certain manures or fertilizers also increase the nitrous oxide in the atmosphere to cause an artificial greenhouse effect. The light absorbed by vegetation is re- radiated as trapped heat are likely to be radiated back in space, but the greenhouse gases hold them to maintain the biospheric temperature.
Burning of fossil fuel and breaking of the permafrost regions also triggers the release of methane gas which is also an artificial side effect of build up of the greenhouse gas.
The solar radiation is another cause of concern which is further increasing the problem of global warming. Though humans are reaping the benefits of industrial revolution it is vital to again control the pollution levels so that the greenhouse gases are controlled.
Global warming is a slow but steady process. The effects are already evident with decline in growth of trees, downpour, floods, natural calamities of varying severity and also a huge level of awareness shown by concerned nations. Though greenhouse gases are naturally present, it is more important to control the artificial re radiation which is caused by humans in a bid to heavily depend on mechanical luxuries and gross negligence.
Each country has a statistical data to find the ecological imbalance it has contributed to in terms of greenhouse gases and corrections are possible. It is just a matter of attitude in altering the temperature of air conditioners or the refrigerator. Simple alteration in life style like using a public transport instead of cars is another way to control the emission.
The natural presence of greenhouse gases is what makes the earth livable or in a case the heat is totally given back to space, the earth would have drastic low temperatures not suitable for living. Hence natural maintenance of the greenhouse effect is essential.
