His point that the case for mitigating against
FF emissions had not gone through a due diligence study would have to be by it's nature vastly more detailed than anything yet undertaken.
Returning to my original point that some «are paying disproportionately» for the externalization of
FF emissions, the people in the states with the ten highest losses paid 4.6 as much per capita as the average, and 125 times as much as in the least affected ten states.
Logically it would also be somewhat a Double return for the «effort» involved — cutting ff use only cuts it, for it doesn't create
a ff emissions sink.
Our gross
FF emissions are around 8 PgC / year.
There is, of course, a weak linkage between
FF emissions & SO2 emissions rather than no linkage.
(Note, I did write «There is no linkage between
FF emissions & SO2 emissions «which is evidently not what the more detailed argument that sentence summated was presenting.
Not exact matches
There is no linkage between
FF CO2
emissions & SO2
emissions, a linkage you assume and without which your Grand Theory very rapidly splash - lands and gurgles round the U-bend.
Thus about 43 % of the annual
FF + cement
emissions of roughly 10Gt (C) increase atmospheric CO2 by about 2ppm, to which should be added an increase due to
emissions from Land Use Change.
MA: «There is no linkage between
FF CO2
emissions & SO2
emissions, a linkage you assume and without which your Grand Theory very rapidly splash - lands and gurgles round the U-bend.»
MA: Munshi then ventures briefly into the issue of calibration of satellite data and in so doing, badly misrepresents Nerem et al (2018) and adds a little Victor - the - Trollishness by plotting 25 - year SLR trends against annual
FF CO2
emissions.
and lastly... this little gem from late 2016, which relates back to queries recently about the accuracy of GHG
emissions FF use numbers, and what the future may hold (if funded properly).
If the warming effects of CO2
emission from
ff were essentially neutralized after the 1940s, then one would expect that a similar neutralization would have been in effect prior to 1940.
Aksel @ 22, The Airborne Fraction of all our CO2
emissions (
FF + cement + land use) that remains in the atmosphere is a little under 50 %, perhaps 45 %.
For the record, I have given up flying (and all
ff - powered long - distance travel), most driving and meat eating... and have worked on every level (family, work, municipal, state, national, international — though the last I mostly leave to my bro who, as head of a major international NGO, is better positioned to influence international entities) to push them to move rapidly to low or no
emissions and low or no
emissions waste, and at great risk to relationships and to my professional career.
That's a wide bow to draw obviously, but it would be equally nice to see some Reviews Papers looking at these interrelated Fluxes and Sequestration potential as a Net gain or Loos being spelled out... and considering these matters into the future based on BAU
FF cement & LU
emissions.
Taking that figure, just to sequester last year's
FF + cement carbon
emissions would thus require an uptake of about 4 tC / ha.
The rate of
emission from holes popping one at every year as estimated by David above is at least 10000 times smaller than other
emissions, e.g. fugitive
FF mining and agricultural that are in the order of 100s Mt CH4.
This would mean not only reducing
FF etc
emissions but simultaneously SEQUESTERING ~ 2GtC per year (NETs soil / vegetation), which might put back 20 % (or more) of the 500 GtC HISTORICAL LULCC Land Use Carbon
emissions?
Or
emissions of CO2 from wood was far more than from
FF in the 1800's.
Making a (less radical) 70 % cut in
ff energy
emissions by 2050 means being asked to replace 17 GtC of «economic» demand in energy at 2050 with something else over and above the bau energy mix projections.
BAU forecasts put
ff energy increasing by another 50 % by 2040 making carbon
emissions ~ 16GtC per year, and 20 GtC in 2050.
They are saying reducing your
emissions give you the opportunity to help those who are taking the cost of using
FF but arent contributing to the problem.
