What is Global Warming?
Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as Carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. This is a type of greenhouse effect. The impact of global warming can be seen in sea level, crops, rainfall, and human health.
What causes Global Warming?
Massive deforestation, burning of fossil fuels, industrial emissions, etc. have resulted to an increase in green-house gases around earth's atmosphere. The greenhouse-gases trap Sun rays in the earth's atmosphere causing the temperature to rise resulting in what is known as global warming.
The heat would have otherwise released if the greenhouse-gases were not present in such huge quantity. The warming of atmosphere due to the presence of greenhouse-gases is called greenhouse effect.
Global Warming:Facts, Causes & Effects.
Global Warming is a term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth's climate. There is great debate among many people, and sometimes in the news, on whether global warming is real(some call it hoax). But climate scientists looking at the data and facts agree the planet is warming. While many view the effects of global warming to be more substantial and more rapidly occurring than others do, the scientists consensus on climate changes related to global warming is that the average temperature of the Earth has risen between 0.4 and 0.8 degree C over the past 100 years. The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels, land clearing, agriculture, and other human activities, are believed to be the primary sources of the global warming that has occurred over the past 50 years. Scientists from intergovernmental panel on climate carrying out global warming research have recently predicted that average global temperatures could increase between 1.4 and 5.8 degree C by the year 2100. Changes resulting from global warming may include rising sea levels due to the melting of the polar ice caps, as well as an increase in occurrence and severity of storms and other severe weather events.
