The issue of global warming

The above scenario is not science fiction but a reality which global warming could cause. Global warming is the increase in the temperature of the earth’s atmosphere caused by greenhouse gases like water vapor, carbon dioxide, methane and ozone. There has been growing awareness and concern among people about this phenomenon. It has become a global issue although it is hotly debated in international circles. It has a fair share of supporters and critics. Its proponents warn that if immediate preventive steps are not taken it will have a disastrous effect on future humankind. Its detractors argue that the problem is grossly overestimated and nothing should be done. They also argue that the steps to tackle the problem will hinder economic progress.
