The climate of the Earth is always changing. In the past it has altered as a result of nat­ural causes. Nowadays, however, the term ‘climate change’ is generally used when referring to changes in our climate which have been identified since the early part of the twentieth century. The changes we’ve seen over recent years and those which are predicted to occur over the next 100 years are thought by many to be largely a result of human behaviour rather than due to natural changes in the atmosphere. And this is what is so significant about current climatic trends; never before has man played such a significant role in determining long-term weather patterns – we are entering the unknown and there is no precedent for what might happen next.
