An Analysis of Climate Forcings from the Central England Temperature (CET) Record

The Central England Temperature (CET) record is the world's longest instrument-based temperature record and covers the years 1659-present. The temperature variation of 0.8°C between the Maunder Sunspot Minimum in the late 17^th Century and the beginning of the Industrial Revolution in the mid-late 18^th Century can be explained by fluctuations in solar output  (TSI) alone. Thereafter, approximately one third of the temperature increase to the present may be attributed to increases in atmospheric CO₂, with the anthropogenic contribution to Global Warming/Climate Change up to the end of the 20^th Century estimated at 0.4 to 0.5°C.
