article on global warming in about 1000 - 3000 words
Answers
Global warming is an increase in the average temperature of the earth’s temperature, especially a sustained change sufficient to cause climate change. The average facade temperature of the globe has increased more than degree since 1900 and the speed of warming has been almost three folds the century long average since 1970.

This increase in earth’s average temperature is called Global warming. More or less all specialists studying the climate record of the earth have the same opinion now that human actions, mainly the discharge of green house gases from smokestacks, vehicles, and burning forests, are perhaps the leading power driving the fashion.
The gases append to the planet’s normal greenhouse effect, permitting sunlight in, but stopping some of the ensuing heat from burning back to space.
Based on the study on past climate shifts, notes of current situations, and computer simulations, many climate scientists say that lacking of big curbs in greenhouse gas discharges, the 21st century might see temperatures rise of about 3 to 8 degrees, climate patterns piercingly shift, ice sheets contract and seas rise several feet.
With the probable exemption of one more world war, a huge asteroid, a fatal plague, or global warming may be the only worst dangers to our planet earth.
Global Warming Causes
The major cause of global warming is the release of green house gases like carbon dioxide, methane, nitrous oxide etc. into the atmosphere. The major source of carbon dioxide is the power plants. These power plants emit large amounts of carbon dioxide produced from burning of fossil fuels for the purpose of electricity generation.
About twenty percent of carbon dioxide emitted in the atmosphere comes from burning of gasoline in the engines of the vehicles. Buildings, both commercial and residential represent a larger source of global warming
