I believe the arguments for high
gas decline rates are made by informed people who truly believe their results.

Under the strictest pathway (RCP 2.6), which assumes an early peak of greenhouse
gas emissions which then
decline substantially, the potential net increases in mortality
rates at the end of the century be minimal (between -0.4 % and +0.6 %) in all the regions included in this study, highlighting the benefits of the implementation of mitigation policies.
Coal consumption, in particular, saw steep
declines by dropping 18 percent, while natural
gas use dipped just 1 percent, versus 2015
rates.
At the same time, however, production from all other sources — such as conventional
gas fields on land and offshore as well as so - called tight
gas and coal - bed methane — has been
declining at a
rate of about 5 percent per year.
Brazil's greenhouse
gas emissions (GHG) fell 4.9 percent in 2012 as
declining deforestation
rates and a drought - induced drop in cattle herds outweighed increased emissions from the energy sector, an independent study showed on Thursday.
Global
rates of temperature change in high and
declining greenhouse
gas emission scenarios.
A dramatic
decline in the ability of the Earth to soak up man - made emissions of carbon dioxide, and a corresponding acceleration in the
rate of increase of greenhouse
gas in the atmosphere, have been detected for the first time by scientists.
IHS and IPIECA argue that
decline rates mean the world will continue to need new oil and
gas projects.
The inappropriately - named «greenhouse» effect is actually the effect of absorption / emission of IR radiation due to radiatively - active
gases combined with the effect of
declining temperature with height of the atmosphere (lapse
rate).
To understand emissions reductions necessary to have a good chance of limiting warming to 2 °C, the climate community has focused largely on emissions pathways — that is, when greenhouse
gas emissions peak and the
rate at which they must
decline (e.g. peak sooner and then reduce less steeply versus peak later and then reduce more steeply).
As Bryce points out, shale natural
gas wells deplete at a very fast
rate: «The new shale
gas wells... have steep
decline curves, meaning that output from some wells may fall by 80 to 90 percent during the first year of production.»
«Although deforestation
rates have
declined since the early 2000s, deforestation and other land - use change still accounts for 14 % of greenhouse
gas emissions in the world.
The major concern over the current massive increase in shale
gas is its very rapid
decline rate.
Its
rate of CO2
decline then increases gradually, reaching 3.3 % by 2020, and 4.4 % by 2050; for all
gases combined, the maximum
rate of
decline reaches 3.4 %.
(Interesting side note, this
rate and also the absolute CO2 emission from electricity generation in NY state has
declined substantially over the past 30 years — mostly due to a shift from coal to natural
gas.)
Because the growth
rate in production is expected to vary (generally ranging from 2 to 4 %), African
gas production is projected to peak at roughly the same time (2035 — 2045) in all three cases before
declining slowly thereafter.
All told, if one assumes that emissions
decline at a steady
rate between each of those milestones, total U.S. greenhouse -
gas output between 2012 and 2050 would be equivalent to about 154 billion tons of carbon dioxide.
If Argentina instead focuses on planning for a managed
decline of already producing fields, emissions from the country's oil and
gas sector could fall largely in line with the
rate of reductions needed to keep warming below 2 degrees Celsius.
Ciardiello expects higher
gas prices and rising interest
rates to trigger a
decline in consumer spending in the casual dining sector.
«We feel that the availability
rate is rising because consumers have turned circumspect due to the slowdown in the housing market and that their spending is being affected by high
gas prices, so retail space absorption is
declining,» says Abigail Marks, an economist at Torto Wheaton.
