GLOBAL WARMING:
Global Warming is the rise in the average temperature of the Earth’s atmosphere, including the surface air and oceans. In simple words global warming is when the Earth heats up. It is caused mainly due to increasing concentration of greenhouse gases in the Earth’s atmosphere. The greenhouse gases, include carbon dioxide, nitrous oxide, methane, water vapor, traps heat and light in the Earth’s atmosphere, which increases the temperature. Today global warming is considered as one of the major environmental issues, which threatens to disrupt the basic balance of the environment and cause large scale destruction.
The Greenhouse Effect:

There are certain gases that raise the temperature by trapping the sun’s heat and energy. The Earth’s average temperature would have been about 60Error! Hyperlink reference not valid. colder if it weren’t for these gases. These gases are referred to as “greenhouse effect” because of the way they help to keep the Earth warm.
The greenhouse effect makes the Earth suitable for all living things. The Earth might have been freezing or it might also have been burning hot if the greenhouse effect did not occur. However, the presence of too many such gases can cause the Earth to get unusually warmer. The plants would not be able to take such heat and eventually they would have died. The scarcity of plants would cause animals to die of hunger and simultaneously resulting in the end of the human race.
Cause of Global warming:
Many things contribute to global warming. The causes can be split into two groups: 1. Natural causes. 2. Man-made or anthropogenic causes. 1. Natural causes:
Natural causes are causes created by nature. The release of methane gas from arctic tundra and wetlands is one such natural cause. Methane, being a greenhouse gas, traps heat in the Earth’s atmosphere resulting in global
