Global Warming - The addition of certain pollutants like the carbon dioxide gases increases the temperature of the earth. These gases remain close to the surface of earth, forming an insulating layer. The surface becomes hot due to the solar radiations. This radiation is normall..

The addition of certain pollutants like the carbon dioxide gases increases the temperature of the earth. These gases remain close to the surface of earth, forming an insulating layer. The surface becomes hot due to the solar radiations. This radiation is normally reflected back into the space. Howe..

Harmful results of Greenhouse Effect is global warming. While the green house gases enable life to exist, problems arise when the atmospheric concentrations of these gases increase. All climate changes up to the industrial revolution occurred naturally as very few gases were re..

Question: What is meant by global warming? Answer: Due to an unhealthy increase in the amount of green house gasses like CO 2 in the atmosphere, there in increase in the temperature of earth. This increase in temperature of earth is known as global war..

Green House Gases - The concept of green house - though identified by man late - is certainly as old as global environment itself. That is, a part of radiation received by earth's surface is reflected back to environment and trapped due to certain gases. These gases are called green house..

It is estimated that in the last 100 years 360 billion tons of CO 2 is added to atmosphere. CO 2 has risen by 7% in the last 30 years. As CO 2 in atmosphere has capacity to trap infrared rays in the band with 2.1 to 15 m m, higher CO 2 in atmosphere has caused global warming (ri..

Along with warmer temperatures and higher humidity, the number of very hot days is expected to rise in many areas around the globe. Heat stress occurs in such conditions and the young, old and poor people are more susceptible to it. High temperatures will reduce work efficiency of human beings. Fu..
