Summary[edit]

To reproduce:
- download data
- from the Cape Grim data: compute yearly averages, place it in columns 7 (value) and 8 (year), name it CapeGrim_CO2_yrly_data.csv (use spaces as separator)
- strip all non-data lines from the law dome data file and name it law2006-dataonly.txt
- run the following gnuplot-script (I used Gnuplot 4.4)
