Global warming is the rising of temperature on Earth. It rises by about one degree Celsius each year, but it is a significant change. It is caused by carbon dioxide, methane and nitrous oxide.
These pollutants can stay for centuries and trap the sunlight bounced off to the Earth's surface. This light could bounce out to space, but the gases trap the light. They are known as greenhouse gases and cause the greenhouse effect.
Global warming is harmful to human beings and the Earth in many ways; for instance, it can cause many natural disasters like- storms, heat waves, floods, and droughts. It would be challenging to live in these conditions.
Global warming can be reduced in our houses with few simple steps. We should always turn the lights and fan off before leaving a room. We should use energy-saving light bulbs, and gradually global warming will reduce.
