We may not have been keeping detailed records ourselves for that long globally but some areas have records going back quite a long way. I said ourselves because Mother Nature keeps records for us which we can recover via analysis of ice cores and tree rings amongst other things.

There are many methods of predicting future climatic conditions and many factors, both natural and man made, which can affect the analysis. Depending on which of those a scientist has taken into consideration can affect the climatic model that is produced. Taking all these models into account there can be a presumption of the way climate will change and the degree of change. This will result in a wide range of possibilities with the truth being somewhere within that range. These predictions have been moving over recent years in a direction that spells huge problems in the not too distant future. As with all research on the subject, the results obtained tend to be more often than not in line with the scientists pre-conception of what is going to happen.
At the end of the day though I sense that climatic change is speeding up without the need for scientific evidence. It is a gut feeling that I hope is wrong.
