Methane is lighter than air and rises in the atmosphere.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that methane is lighter than air and rises in the atmosphere?

Yes. A reference encyclopedia entry states that methane gas at ambient temperature is lighter than air, and a medical reference and a viscosity dataset likewise describe methane as lighter than air. These sources support the density half of the claim; none of the placed items explicitly describes methane rising in the atmosphere.
