The most prominent among the greenhouses gases is the carbon dioxide. The maximum amount of this gas is produced in America and Europe. The greenhouse gases raise the atmospheric temperature.
It is told by the Intergovernmental Panel on climatic change that the Global Mean Temperature of the atmosphere has raised by about one degree Fahrenheit (0.55 degree Celsius) in the 20th century and by the end of 21st century the world may get warmer by about 3.5 degrees.
The effect of this global rise in temperature is stupendous. It is likely to bring about severe climatic changes. It can lead to greater evaporation of water from oceans and water reservoirs.

ADVERTISEMENTS:
This means that world will become rainier and moister. This can make the northern latitudes greener. But it can also cause devastating floods, as the rainfall pattern changes the world over.
One greatly devastating effect of the greenhouses gas can be visualized from the almost certain possibility that the global warming will make the snow on mountains melt more quickly- This will mean more water in oceans and accordingly, some islands, and sea-coasts in certain parts of the world may get submerged.
It is of utmost importance that the production of greenhouse gases at such an alarming scale should be checked. This will also reduce pollution all over the world, particularly in urban areas.
ADVERTISEMENTS:
In brief, Global warming is caused due to burning of coal, oil, wood, fossil etc. Some gases used in refrigerators and perfumes are greatly responsible for thinning of the ozone layer over the earth’s atmosphere. This also leads to global warming.
The remedy lies in checking those practices and in making the increasing use of renewable energy.
