    The process of harvesting "natural gas" (aka: methane) from the ground tends to be "leaky," allowing a percentage of the methane to escape directly into the atmosphere.

    The study looks at how much gas is released into the atmosphere, revealing a significant jump in atmospheric methane. Methane, as compared to CO2, has the potential to trap over 100 times more heat over the course of ten years, making fracking one of the most environmentally destructive ways to source energy.
    Fracking is the leakiest of the methodologies, because they're basically just cracking rocks to release deposits. If you've ever broken rocks, you know that they are entirely unwilling to break in tidy straight lines. This means a lot of the gases released are not harvested into tidy little tanker trucks, but instead bubble up to the surface and escape into the atmosphere.

      Nothing in the Cornell study cited by the article supports your physical description of fracking above.

      The emissions cited in the Cornell study are released
      to the atmosphere as a result of well production pipe casing transport of methane to the surface and the emission point is at the surface.   However, no part of those emissions originated in the hydraulic fractured strata with vertical transport via diffusion through rock layers outside of the production casing.
