Global Warming

Global warming has become one of the serious problem in today's world.It has been increasing in an Alarming rate.People are directly or indirectly the cause for global warming.Due to global warming there has come a drastic change in the field of environment.Today we people are unaware about the present status of the climate.the climatic condition has been deteriorating day by day.It is the rising average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's average surface temperature has increased by about 0.8 °C (1.4 °F), with about two thirds of the increase occurring since 1980.Warming of the climate system is unequivocal, and scientists are more than 90% certain that most of it is caused by increasing concentrations of green houses gases produced by human activities such as deforestation and the burning of fossil fuels.These findings are recognized by the national science academies of all major industrialized nations.An increase in global temperature will cause sea level to rise and will change the amount and pattern of precipitation and a probable expansion of subtropical deserts Warming is expected to be strongest in the Arctic ocean and would be associated with continuing  and sea ice.
