Maybe.?? The problem is that LNG if it escapes into the environment is a
worse greenhouse gas than CO2, although not as stable.?? So if you take
into account the large amounts of gas lost to the atmosphere with
fracking,
I could see it looking pretty bad.

there are leaks from garbage dumps where decomposition is taking

melting and releasing methane while the Permafrost is collaping
into large pits releasing more methane. Satellites are detecting
plumes of this gas in the atmosphere.

There are probably more methane leaks from natural seeps in the seabed
of the Gulf of Mexico than anywhere else in the planet.  At 2,000 feet
below the surface to 10,000 feet below the surface, there is six feet of
frozen methane covering the entire Gulf of Mexico seabed.  The frozen
methane is constantly sublimating and rising to bubble up into the
atmosphere.

It may be that man-made leaks add to the volume that reaches
the surface, which is bad, but the bulk of the carbon in
naturally seeped CH4 returns to the sea floor and never
reaches the atmosphere.

We humans did not cause this, it is nature.  And this phenomena happens

Research indicates that while a significant fraction of leaked methane may be consumed by microbes or dissolved in seawater, a notable percentage still makes it to the atmosphere. Studies suggest that approximately 10% to 50% of leaked natural gas may escape into the atmosphere depending on various environmental conditions and specific locations.
In summary, while not all carbon from natural methane leaks on the sea bottom reaches the atmosphere due to microbial consumption and dissolution processes, a measurable amount does escape into atmospheric circulation under certain conditions.
