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 1900's. The changes we've seen over recent years and those which are predicted over the next 80 years are thought to be mainly as a result of human behaviour rather than due to natural changes in the atmosphere.
The greenhouse effect is very important when we talk about climate change as it relates to the gases which keep the Earth warm. It is the extra greenhouse gases which humans have released which are thought to pose the strongest threat

I stop thinking that a lot of weather changes were due to natural causes a long time ago. Of course we try to reverse the affects of what we do to our world with new cars and other stuff but at a very high expense. 80 years from now many of us wont be here for it to get any worse

I think we are overreacting. The reality is, we are basing our "normal" temperatures and weather patterns on data that has only been collected for a little over a century.
Who is to say that, the weather we're experiencing now isn't normal and we've just been experiencing colder weather for the last 100 years.
