methodology: "- Extracted numbers from the original figure (see citations below), where the time series were derived from the NCEP/NCAR reanalysis (Kalnay et. al 1996) using a modified version of Serreze (1995) as detailed in Wang et. al 2012.\r\n- Computed ten-year averages\r\n- Plotted the results"
