FIGURE 3 California future BAU total (enteric fermentation plus manure management) CH 4 emissions, comparison of these emissions converted to CO 2 eq and CO 2 we using GWP and GWP*, respectively, and cumulative CO 2 eq and CO 2 we with emissions-forced warming. The x -axis represents years and the y -axis represents annual CH 4 emissions (A) , annual CO 2 eq or CO 2 we (B) , or cumulative CO 2 eq or CO 2 we (C) . CO 2 we are represented in (B, C) by the blue solid line (“GWP*”), CO 2 eq are represented by the red solid line (“GWP”), and temperature is given in (C) by the dashed black line (“Warming”). The temperature axis (C) is scaled by 0.001 mK/TgCO 2 , or 1 K/TtCO 2 , as in Figure 2.
