It is recommended to name the SVG file “Greenland ice sheet temperatures Vinther et al 2009.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
Summary
| Description |
English: The temperature reconstruction produced using data from all six ice cores is shown by the black line in the attached figure, and spans the period from 9690BC to AD1970. The blue lines represent two focus on the dataset, first on the Late Holocene (or Meghalayan) and then on the last millenium. It has a resolution of around 20 years, meaning that each data point represents the average temperature of the surrounding 20 years. So, the end of the record – 1970 – shows the average temperature between 1960 and 1980.
The original data for the creation of these figures have been downloaded from the NOAA website: ftp://ftp.ncdc.noaa.gov/pub/data/paleo/icecore/greenland/vinther2009greenland.txt ORIGINAL REFERENCE: Vinther, B.M., S.L.

I made these figures to propose a correct version of the previous figure made by Artreve. His version used incorrectly the stated baseline (1880-1960 average) and missed the last centuries from the dataset.
