“The short-lived climate pollutants [like methane] that we emit from human activities are basically controlling how fast the warming occurs, she said. This is because they are very powerful at absorbing radiation."[1]
Methane is CH4. It is a powerful greenhouse gas. It degrades over 8 to 12 years in the atmosphere, as it converts into carbon
dioxide (CO2). There are three different
sources of methane gas including thermogenic (from deep geology), anthropogenic
(from human activities) or biogenic
(from living organisms ) methane[2]. “Natural” gas is composed of 85 to 99%
methane, mostly thermogenic methane.
The global warming
potential of CH4 has been upgraded by IPCC to at least 86 times stronger than
CO2 during a 20 year time frame of this gas, and 105 times stronger over a 10
year time frame. Methane, grouped with
other near-term climate forcers such as black carbon, hydrofluorocarbon and
aerosols, is the most likely greenhouse gas escalating the planetary heat now,
because there is so much of it being released.
There have been few measurements of gas leakage from gas wells and
pipelines. The measurements that have
been made have found substantial concentrations of methane in the
atmosphere. Further, the EPA comparison
of methane to CO2 on the 100 year time frame claims methane is 25 times
stronger than CO2, hiding the real impact of CH4’s near-term presence. Simply, the 100 year time frame does not
acknowledge methane’s impact.
The current atmospheric
concentrations of CO2, methane and nitrous oxide have levels unprecedented in
the last 800,000 years.[3] There is great concern about the absence of
data collected of actual measurements of emissions. Fugitive methane emissions have been
measured in only a few cities: San Francisco CA, Manhattan, NY[4],
Washington DC, Boston MA, and several small towns. The urgency to address
climate change should be based on the actual impacts of this potent GHG. Bryce Payne, PHD and two other scientists
wrote to the White House and State Department that the GWP (global warming
potential) of methane needs be positioned even shorter than 20 years, it should
be a 10 year time frame. This will allow
us to understand what we are facing and to act appropriately to reduce the
changing of our planet’s climate.
Methane leakage impacts arise from man-made sources that include natural gas pipeline leakage, leakage and venting of upgrading pipelines, abandoned old wells, new wells, gas or oil storage fields (these are highly pressurized for example near Porter Ranch), migration underground that rises to the surface, and emissions from waste water disposal and earthquakes, venting methane in oil well fields, and more. This is happening in the US and in other countries. Evidence of leakage can be seen in the images attached here.[5] Damascus Citizens for Sustainability (DCS) has conducted methane emissions measurements in rural areas where methane escaped and has travelled beyond the target production zone underground, connected existing faults and fractures allowing gas to migrate to aquifers and the surface.

Wyalusing area showing elevated methane (geological leakage) over a wide area in Susquehanna County, PA along the Susquehanna River This is data obtained with a Picarro CRDS machine which produces very accurate measurements of methane to 1/2 ppm. Chesapeake, the gas driller in the area, was fined $900,000.by Pennsylvania DEP for causing gas migration. The area picture is detailed in the May 16 PA DEP Consent Order (post damage arrangement) which has the maps that are made by the yellow and blue points in the image. At least one lawsuit was settled there for $1.6 million and there are many more filed.

Results of methane survey
of parts of Manhattan and rural areas to the East on 27-30 November and
December 2012.
DCS reported on fugitive
emissions of Manhattan in 2012 and in New York City Gas Safety Inc. in 2015
determined that at least 6.6% of the total delivered gas is leaking although
likely much more. [6]
Natural gas brings
substantial and devastating health impacts.
DCS has participated in a compendium of health impacts from fracking.[7]
Methane is an indicator gas for the mixture that is natural gas. The mixture includes radon, endocrine
disruptors, benzene toluene VETX , and more. Methane creates asthma from ozone
and burning the gas emits ultrafine particulate matter, under 2.5 microns–these
are like breathing someone else’s tobacco, an impact that it is overlooked.[8] Global health agencies have encouraged
awareness of air pollution-related diseases that causes over 6 million deaths
every year. [9]
A quote from Bryce Payne, PhD [10]
SITUATION IN BRIEF
"It is essential that all UNFCCC (Cop 21) Parties and the global citizenry be as clearly informed as possible with respect to potential climate change and what is being done to mitigate anthropogenic forcing of the climate compared to what is actually necessary if disruptive climate change is to be minimized. If climate change mitigation efforts are to be effective, the short-term impacts of potent, short-lived greenhouse gases, especially methane, must be considered. In the near term, methane emissions due to human activity have a stronger global warming impact than the much larger emissions of carbon dioxide. Current greenhouse gas inventory and reporting rules of the UNFCCC are causing the climate impacts of greenhouse gases such as methane to be effectively ignored."

scientist, Bryce Payne, PhD and professor Ron Bishop, PhD regarding damage that
is happening to the underground, the place of the most biomass in our
planet.
