increasing at a
rate of approximately 0.25 % per year (or 12.5 % change

in 50 - years could be 300 % (as per Isaken et al (2011) case 4XCH4; which would require an additional 0.80 GtCH4 / yr of methane
emissions on top of the current
rate of methane
emissions of 0.54 GtCH4 / yr)?

emissions continue on this path.
It needs to be spelled out, because the «solutions» that are acceptable to the business world (carbon credit trading and attempts at burying CO2

increase around 2100.
But the sheer

Rate of percentage annual growth for carbon dioxide has certainly increased since the beginning of the 21st century, but this should result in a significant change in the rate of warming any more quickly than the differences between emission scenarios would, and there (according to the models) the differences aren't significant for the first thirty - some years but progressively become more pronounced from then on — given the cummulative effects of accumulated carbon diox

Moving on to assess the influence of fossil fuel

The numbers are striking:
in the 1990s, as the market integration project ramped up, global
emissions were going up an average of 1 percent a year; by the 2000s, with «emerging markets» like China now fully integrated into the world economy,
emissions growth had sped up disastrously, with the annual
rate of
increase reaching 3.4 percent a year for much of the decade.
The choice is between leaving CO2

The annualised average growth
rate in global CO2
emissions over the last three years of the credit crunch, including a 1 %
