DescriptionGreenland ice sheet temperatures interpreted with 18O isotope from 6 ice cores.png
English: The temperature reconstruction produced using data from all six ice cores is shown in the source below, and spans the period from 9690 BC to AD 1970. The attached figure does not include the end record. It has a resolution of around 20 years, meaning that each data point represents the average temperature of the surrounding 20 years. The end of the record – 1970 – showing the average temperature between 1960 and 1980 - is not displayed on this figure (see the source below).
