From WUWT, Roy Spencer's article "atmospheric CO2 increases" how did he go from fig 1 to fig 3 ? i get that he's converting ppmV to mmtC ... so that as the proportion of CO2 increases, so many million of tons of C were added to the atmosphere, but fig 3 doesn't look like i'd've expected it to, given fig 1 ... very specific, identifiable annual rises and falls (almost tidal) ?
