Global Warming

Global warming is the greatest challenge facing our planet. It is, in fact, the increase in the temperature of the earth’s neon-surface air. It is one of the most current and widely discussed factor. It has far-reaching impact on biodiversity and climatic conditions of the planet. Several current trends clearly demonstrate that global warming is directly impacting on rising sea levels, the melting of ice caps and significant worldwide climate changes. In short, global warming represents a fundamental threat to all living things on earth

Global average temperature rose significantly during the past century. The prevailing scientific view is that most of the temperature increases since mid-20thcentury has been caused by increases in atmospheric greenhouse gas  concentrations produced by human  activity. Most scientists agree that planet’s temperature has risen 0.5 degree Celsius since 1900 and will continue to increase at an increasing rate. As a result, the world is getting warmer. The year 1990 was the hottest year in the last century

Together with 1991 , the years of 1983, 1987 1998 and 1989 have been measured to be the warmest six years in the last hundred years. The year 1991 was the second warmest year of the past century. The consequences of the rise in temperature is being felt all over the globe the findings of scientific research done in this field reveal that the temperature of the earth likely to rise from 1.4 C to 5.8 C within a period of 100 years.

Unfortunately, the imbalance which we have created between our life and earth is  already showing the signs disasters in the form of flood, cyclones, landslides, tsunami, drought, etc. if the imbalance continues to rise, one day this will pose a question mark on the existence of this planet. Carbon dioxide (CO2) which is an important constituent of environment is causing a warming effect on the earth’s surface.

It increases the evaporation of water into the atmosphere. Since water vapour itself is a greenhouse gas, this causes still more warming. The warming causes more water vapour to be evaporated. The CO2 level is expected to rise in future due to ongoing burning of fossil fuels and land use change. The rate of rise will depend largely on uncertain economic, sociological, technological and natural developments. Other gases such as methane, CFCs, nitrous oxide, tropospheric ozone are also responsible for global warming. Increases in all these gases are due to explosive population growth, increased gases are due to explosive population  growth, increased industrial expansion, technological advancement, deforestation and growing urbanization, etc

 Tree play a significant role in the global carbon cycle. They are the largest land-based mechanism for removing carbon  dioxide from the air. Deforestation is checking these positive processes. It is the second principle cause of atmospheric carbon emissions entering the atmosphere, by the burning and cutting of 34 million acres of trees each year. Every day over 5500  acres of rainforest are destroyed. As a consequence of massive loss of forests, global CO2 levels rise approximately 0.4 per cent each year, the levels not experienced on this planet for millions of years. As we know the forests are the great absorbs of CO2.

There is a close relation between global warming and population growth. Today the large population on earth is using the technologies which are destructive for the earth. Approximately, 80 per cent of atmospheric CO2 increases are due to man’s use of fossil fuels either in the form of coal, gas or oil. A large portion of carbon emission is attributed to the burning of gasoline in internal –combustion engine of vehicles. Vehicles with poor gas mileage contribute the most to global warming. Besides, the sulphur group gas is the most harmful for this. Its contribution is 30 per cent in global warming. This gas is also emitted from the burning of fossil fuels.
