Answer :


Effect Of Global Warming

 
Can you imagine that within 40 years the only glacier that feeds our seven rivers will disappear, causing massive floods, and then dry up, leading to severe drought for our children ?


This may sound a nightmare to some and a distant possibility to others. The reality is that global warming has already resulted in a deficient rainfall across the country, unexpected changes in climate, shrinking of winter season and the rising of average temperature. It is going to hit farming community the hardest. The coastal areas are in danger of tsunami like disasters. The shortage of water and power will affect our industry, too.


What can we do ? It is an important question. We cannot reserve global warming by issuing advertisements, organising seminars and conferences, and engaging in such symbolic acts. Not only the government but the common man also will have to be active to cope with the problems caused by global warming.


We, in India, have to change our lifestyles. Among the immediate and radical steps we can take are : partial ban on the use of private vehicles, cutting down the emission of C$o_{2}$through afforestation, adopting zero waste system, punishing the polluters, etc.


If we do not wake up even now, the ghost of global warming will turn our Dreamland into a nightmare.

Answer 2

Throughout its long history, Earth has warmed and cooled time and again. Climate has changed when the planet received more or less sunlight due to subtle shifts in its orbit, as the atmosphere or surface changed, or when the Sun’s energy varied. But in the past century, another force has started to influence Earth’s climate: humanity
How does this warming compare to previous changes in Earth’s climate? How can we be certain that human-released greenhouse gases are causing the warming? How much more will the Earth warm? How will Earth respond? Answering these questions is perhaps the most significant scientific challenge of our time. Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. The global average surface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6° F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years. Temperatures are certain to go up further. Earth’s temperature begins with the Sun. Roughly 30 percent of incoming sunlight is reflected back into space by bright surfaces like clouds and ice. Of the remaining 70 percent, most is absorbed by the land and ocean, and the rest is absorbed by the atmosphere. The absorbed solar energy heats our planet. As the rocks, the air, and the seas warm, they radiate “heat” energy (thermal infrared radiation). From the surface, this energy travels into the atmosphere where much of it is absorbed by water vapor and long-lived greenhouse gases such as carbon dioxide and methane. When they absorb the energy radiating from Earth’s surface, microscopic water or greenhouse gas molecules turn into tiny heaters— like the bricks in a fireplace, they radiate heat even after the fire goes out. They radiate in all directions. The energy that radiates back toward Earth heats both the lower atmosphere and the surface, enhancing the heating they get from direct sunlight. This absorption and radiation of heat by the atmosphere—the natural greenhouse effect—is beneficial for life on Earth. If there were no greenhouse effect, the Earth’s average surface temperature would be a very chilly -18°C (0°F) instead of the comfortable 15°C (59°F) that it is today.
