Global warming is a term that has been banded about a lot by the media but many of us are still not much clearer about what it actually is. In simple terms, global warming is an increase of the temperature of the earth. This may sound great to some of us who live in slightly colder climates. However, it is not such a great thing. If the planet gets hotter even by as much as a couple of degrees the results could be catastrophic. Global warming is the result of greenhouse gases such as CO2 in the atmosphere. If the temperature increases, the ice caps will melt which will result in sea levels rising and many countries with cities close to the sea risking being submerged under water. A way that you could help combat this is to switch to a more eco friendly source for your electricity such as Good Energy.
