A warming trend can be observed from 1659, the start date of Central England Temperature (CET)- the oldest instrumental record in the world- to today. It would be a notable coincidence if the warming started at the exact point that this record began. The purpose of this paper is to reconstruct CET from its current start point, through the use of diverse historical records, to 1538, in order to see if the commencement of this centuries long warming trend can be identified from within this time frame.
