The wording of the article - and also of the title here - is very misleading.
> Methane accounts for half of the average 1.0 degrees C of warming the world suffered over the past decade and reducing methane is the fastest strategy available to reduce warming. The United States, in partnership with the European Union, is leading the Global Methane Pledge to reduce overall methane emissions by 30 percent below 2020 levels by 2030.
Reducing yearly methane emissions will NOT reduce warming. The article is about reducing the amount of additionally emitted methane in the future.
