Powerful Global Warming Pollution Cut by New U.S. Rules – Scientific American

Radiative transfer models used in climate models show that 2 PPM methane has almost no effect on Earth’s radiative balance, and that even a 10X increase would have almost no impact. And it oxidizes quickly in the atmosphere so the concentration could never get very high in Earth’s atmosphere anyway.

The only thing “powerful” is the level of bullshit by Scientific American and the White House.
