The radiations from the sun enter the Earth’s atmosphere but are unable to escape. This increases the temperature of the Earth. This is called the greenhouse effect. Gases that cause the greenhouse effect are responsible for increasing the temperature of the Earth and thus contributing to the phenomenon called global warming . Thus Global Warming is an increase in the earth's atmospheric temperatures widely due to an increase in the greenhouse effect resulting especially from pollution.

  • Global warming is melting of ice from poles because of the increase in the extent of carbon dioxide. If due to global warming all the ice from our poles melt into water, the water level on earth increases and submerge the land. 

  • Another major cause of global warming is deforestation. 

Good effort everyone. Keep posting !!!

 Global warming refers to the rising average temperature of Earth's atmosphere and oceans and its projected continuation. In the last 100 years, Earth's average surface temperature increased by about 0.8 °C (1.4 °F) with about two thirds of the increase occurring over just the last three decades.Warming of the climate system is unequivocal, and scientists are more than 90% certain most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and burning fossil fuels...

When the level of green house gas in the atomsphere increses due to factory smoke, car fumes, the heat retained increses the earth. This is called Global warming.

Global warming is when the earth heats up ( the temperture rises ). It happens when greenhouse gases ( carbon dioxide, water vapour, nitrous oxide, and methane ) trap heat and light from the sun in the earth's atmosphere, which increases the temperature.
