a. What is Global Warming?
Global warming is known the increase of the average temperature on Earth. As the Earth's temperature increases, disasters like hurricanes, droughts and floods are getting more frequent.
Over the last 100 years, the average temperature of the air near the Earth´s surface has risen less than 1 degree Celsius. It is responsible for the increase in storms, floods and forest fires we have seen in the last ten years, say scientists.

b. What are greenhouse gases?
Greenhouse gases is tiny layer of gas around a huge bulky planet. But it is this gaseous outer ring and its misleadingly called greenhouse effect that makes life on Earth possible – and that could destroy life.
The sun is the Earth’s primary energy source, a burning star that we can feel its heat from over 150 million kilometers away. Its rays enter our atmosphere and shower upon on our planet. About one third of this solar energy is reflected back into the universe by shimmering glaciers, water and other bright surfaces. Two thirds, however, are absorbed by the Earth.
