what to do..

Global warming is the increase in the average temperature of Earth’s near-surface air and oceans since the mid-20th century.
he recently concluded Copenhagen Summit 2009 reiterates again the increasing need for us human beings to heed the earth?s warning about climate change. The Copenhagen talks was part of the annual series of UN meetings, originating from the Earth Summit held in 1992, which aimed at coordinated international action against climate change.
So, what is this climate change and how is it happening? How do we stop it or how do we help?
Climate change is a change in the distribution of weather over periods of time that ranges from decades to millions of years. It can either be a change in the average weather or a change in the distribution of weather events. Climate change may be just limited to a specific region, or may occur across the whole Earth.
In the recent context climate change refers to the changes in modern climate, more generally known as the global warming.
