Global warming is the warming near the earth's surface that results when the earth's atmosphere traps the sun's heat. ... As the earth gets warmer, there will be a rise in the average water level of the oceans. Two factors will cause this rise: thermal expansion and melting polar ice caps. ... It will also reduce the air pollution and improve the quality of the air we breathe. ... Cost is also a problem. ...

If temperature rise pass this tipping point, this cannot be reversed and could soar by 60C in no time (IPPC, 2007). ... As global temperature continue to increase in the climatic system, other tipping elements are also triggered or pushed further to their tipping points some of these elements are mentioned below. ... As ice sheets melt at their edges, their albedo is reduced, but they can also get thinner. ... Greenland ice sheets can contribute almost 16.5-53.8cm to global sea level rise just this century alone depending on the rate of its decay (Pfeffer et al., 2008). ... Ocean water is ...
