WebDec 17, 2016 · In 2015, the Annual Greenhouse Gas Index was 1.37, which represents a 37 percent increase in radiative forcing (a net warming influence) since 1990 (see Figure 1). Of the greenhouse gases shown in Figure 1, carbon dioxide accounts for by far the largest share of radiative forcing since 1990, and its contribution continues to grow at a steady rate.
