evidence: Counterintuitively, using GWP* also indicates that reducing methane emissions would have greater climate benefits than conventionally assumed. To understand this, assume that methane emissions have historically been at a high level and that those methane emissions then start to decrease. Temperatures would soon start to fall as well. This is accurately represented by GWP*, as shown in the figure below. Using GWP-100, on the other hand, to estimate the effect of falling methane emissions would indicate that warming is continuing, just at a slower rate than before. In other words, standard GWP metrics underestimate how much reducing methane emissions would help stabilize the climate.
