If we assume that delivering energy volcanically is associated with about 1 % of the energy beg released as
potential / kinetic energy, this means that a 1 C

potential / kinetic energy
equivalent to lifting the ocean bed some 4 meters, which would generate an enormous tsunami.
Or, trying to «correct» for the different lifetimes of the gases using Global
Warming Potentials, over a 100 - year time horizon (which still way under - represents the lifetime of the CO2), you get that the methane would be
equivalent to increasing CO2 to about 500 ppm, lower than 750 because the CO2 forcing lasts longer than the methane, which the GWP calculation tries in its own myopic way to account for.

They compared estimated emissions for shale gas, conventional gas, coal (surface - mined and deep - mined) and diesel oil, taking into account direct emissions of CO2 during combustion, indirect emissions of CO2 necessary to develop and use the energy source and methane emissions, which were converted to
equivalent value of CO2 for global
warming potential.
An ambitious HFC agreement has the
potential to avoid 100 billion CO2 -
equivalent emissions by 2050 and 0.5 °C

Warming Potentials (GWP) used for presentation of CH4 and N2O in terms of CO2
equivalent are 21 and 310, respectively.
The
equivalent carbon dioxide emission is obtained by multiplying the emission of a well mixed greenhouse gas by its Global
Warming Potential for the given time horizon.
A global phase - down could avoid 1.1 — 1.7 billion metric tons CO2
equivalent (CO2
equivalent is a measure used to compare impacts of greenhouse gases based on their global

An appropriate choice of the conversion to express the impact of methane in terms of CO2 -
equivalents (the «global
warming potential,» or GWP) is essential to achieving the Paris accords.
The Intergovernmental Panel on Climate Change (IPCC) estimates global anthropogenic greenhouse gas emissions for 1990 at 39.4 billion tonnes of carbon dioxide
equivalent, suggesting that the Nigerian emissions may have represented approximately 0.09 % of the total in terms of CO2 and 0.76 % of the total in terms of methane, using the IPCCs 100 - year global
warming potential for methane of 25.
To make comparisons easier, we convert the global
warming potential of all emissions to units of carbon dioxide
