Causes of the Global Warming

Now I will talk about the causes of the global warming. There are two main reasons for global warming the first one is the "greenhouse effect". A greenhouse gasses (carbon dioxide and methane) effect on the earth with huge amount and the reason for that is the higher concentration of greenhouse gases like carbon dioxide in the atmosphere, the more heat energy will be reflect back to the earth.. The second cause is human activities. Most scientists think that human activities are leading to global warming by using the CO2 which add greenhouse emissions to the atmosphere. Also using the fossil fuels, electricity from coal and driving cars are take part to the rise of the greenhouse. The carbon dioxide and other gasses that are in the atmosphere trapping the sun's heat and causes increasing in earth's warm.
