What is Global Warming?

Global warming is something we all have to take seriously or our children and grandchildren will blame us for not doing what is right.

Global warming is the increase in the average temperature of the earth in the last century, which continues to increase and won’t stop increasing until the people make an effort to stop it. Global warming happens due to the greenhouse gases, which are let in the atmosphere by humans. It happens like this, first the humans pollute the atmosphere with greenhouse gases, then these gases act like a mirror to the sunrays, which are reflected from the earth so they bounce back to earth. This makes the average temperature of the earth increase, which make glaciers melt and the water goes to the sea, which makes the sea level rise. The rise in sea level and the increase in temperature will both have a big impact on everything living on this earth.

To stop this complex problem we should all do something to stop this from happening. If we do our children and grandchildren could live in a safe unpolluted world.
