About Global Warming


Global warming is the increase in the average temperature of Earth's near-surface air and oceans since the mid-20th century and its projected continuation. The average facade temperature of the globe has augmented more than 1 degree Fahrenheit 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.

Almost every scientist, environmentalists and other specialists have the same opinion that human actions including the discharge of green house gases from smokestacks, vehicles, and burning forests, are the leading factors behind this.

The green house gases mainly including carbon dioxide, methane and nitrous oxide allow the short wavelength sun radiations to enter the earth’s atmosphere, but stop the long wavelength heat radiations to escape out of earth’s atmosphere, thus heating the earth more than what it would have in the normal course.

Based on the study on past climate shifts, notes of current situations, and computer simulations, many climate scientists believe that following the lacking of big curbs in greenhouse gas discharges, the 21st century might see temperatures rise of about 3 to 8 degrees, thus, shifting climate patterns, contracting ice sheets and rising the sea levels. With the probable exemption of one more world war, a huge asteroid, or a fatal plague, it can be rightly assumed that global warming may be the only most danger to our planet earth.
