The emissions graphs enable the user to view on-screen the input emissions scenarios that were used in running MAGICC. Only emissions from 1990 to 2100 for the four main gases are available to view (although some scenarios in the MAGICC library extend to 2400). The graphs initially display both Reference and Policy scenario curves, but these can be selectively turned on or off using the buttons on the left hand side of the plotting area. For SO2 emissions, the three regional scenarios are shown separately. For CH4 and N2O, the emissions displayed are total (anthropogenic plus natural) emissions after application of a year-2000 budget-balancing algorithm. In general, these values will differ from the user-defined input values. For CO2, displayed and input values are the same. For SO2, displayed emissions are absolute values, while input values are given relative to 1990. To convert to absolute values, the assumed 1990 values are: 37TgS for NAM-EUR, 28TgS for ASIA and 10TgS for ROW (as is clear from the left-hand axis of the graph).
If you wish to produce a hard copy plot of any graph the Print button will generate a print of your screen directly on an attached printer. Note that this direct print option will not work with all printers. The EPS file button (used to produce an encapsulated postscript (EPS) file in earlier versions of MAGICC/SCENGEN) is not working in the current version.
A further alternative is to use the Windows Alt-Prnt Scrn facility to port the graphics window to a Word document.
