But the authors of the new paper also argue that
keeping emission rates flat for 50 years is no longer compatible with keeping carbon dioxide levels below 500 parts per million.
«Because anthropogenic emissions exceed removal rates through natural carbon sinks,
keeping emission rates the same will not lead to stabilization of carbon dioxide.
Because human carbon dioxide emissions exceed removal rates through natural carbon «sinks,»
keeping emission rates the same will not lead to stabilization of carbon dioxide.

If China's use of renewable and nuclear energy grows at a plausible
rate, and the country captures some of its
emissions from coal - burning power stations and
keeps making improvements in energy efficiency, by 2050 its total
emissions could end up 4 per cent lower than today, says Zhou.

rates too low for too long and printing too much money — what Buffett describes as «Greenback
emissions» — will result in inflation measurable in the CPI in the not too distant future.
Keep in mind that the Intergovernmental Panel on Climate Change last year concluded that a freeze on global
emissions now wouldn't have a measurable impact on warming
rates for several decades.
The system is trying to turn it all back into O2, but it just can't
keep up because of the rapid
emission rate.
The paper appears to conclude that if we wait 20 years to begin reducing GHG
emissions, assuming a modest amount of mitigation in the short term, we will have to reduce
emissions at a 3 to 7 times greater
rate than if we start now in order to
keep warming to a 3 degree C increase around 2100.
However, «study after study predicts that carbon
emissions will
keep growing by roughly three percent a year — and at that
rate, we'll blow through our 565 - gigaton allowance in 16 years, around the time today's preschoolers will be graduating from high school.»
«Unless we find ways to capture the carbon
emissions from those plants at affordable
rates we're going to
keep warming the planet.»
bozza @ 354, even
emissions at 10 % of current
rates would be sufficient to
keep on increaseing atmospheric CO2 concentrations, and ergo prevent net ocean outgassing of CO2.
In fact,
keeping 2ºC within reach means that even if Annex I
emissions drop at a
rate that's steep enough to bring them to the stringent edge of the 25 - 40 % range (that is, 40 % below 1990 levels in 2020), then non-Annex I
emissions will need to have peaked and begun to decline by 2020.
Increases in the
rate of anthropogenic
emissions of CO2 do not
keep pace with the
rate of increases in atmospheric CO2, because the CO2 from anthropogenic sources are negligible enough to be on the limits of detectable measurement.
If we can slow
emission growth
rates below the previous exponential
rate, nature could
keep up better and that sink fraction may exceed a half.
The team calculates that if
emissions» reductions began today, they would need to occur at the
rate of 6 percent per year (whereas if they had started in 2005, they would only have needed to be 3.5 percent per year) to
keep the global temperature within about 1 - 1.5 degrees Celsius of preindustrial levels.
Lam and team used climate models from the Intergovernmental Panel on Climate Change to examine the economic impacts of climate change on fish stocks and fisheries revenues under two different
emissions scenarios: a high -
emission scenario, in which the
rates at which greenhouse gases are pumped into the Earth's atmosphere continue to rise unchecked, and a low -
emission scenario under which ocean warming is
kept below two degrees Celsius.
This limited range of pathways all have a
rate of warming less than 0.2 °C per decade, which initially suggests that a cumulative
emissions target could be used to constrain
rates of warming, assuming that
rates of decline are
kept at less than 4 per cent per year.
Simply stated: the IPCC predicted that if human
emissions of CO2
kept growing in a business - as - usual (BAU) manner, the world would experience a high likelihood of global warming acceleration - to a per century
rate of 2.8 °C.
The
rate at which the world would have to move to zero
emissions to
keep global temperatures from rising more than two degrees Celsius.
Slowing the growth
rate of GHG
emissions and then reversing it is the key to addressing climate change and
keeping global average temperature below 2 °C above pre-industrial levels.
At current annual
rates of ~ 41 Gt CO2 for fossil fuels, industrial and land - use
emissions combined (Le Quéré et al 2017), time is running out on our ability to
keep global average temperature increases below 2 °C and, even more immediately, anything close to 1.5 °C (Rogelj et al 2015).
As it is, nature can't
keep up with the
emission rate.
To
keep revenues up, carbon tax
rates must continually increase as
emissions decline.
But they have not been doing so at a
rate consistent with
keeping cumulative carbon
emissions low enough to reliably stay below the international target of less than 2 degrees Centigrade of global warming.
Rather, it rapidly accelerates the problem, since global
emissions are increasing at a substantial
rate such that generation D would be
kept below some crucial climate threshold, but delay would mean that they would pass that threshold.
the moeny denialists make will not matter if we
keep going at the
rate we are going; then when they concede they want to do dangerous things; carbon capture in the ground... forget about reducing actual
emissions and alternative energy sources, let us just bury everything... sickening really.
Reduce Deforestation by Half Reducing deforestation
rates by 50 % by 2050 and then maintaining them there until 2100 would avoid emitting the equivalent of 12 % of the
emissions needed to
keep atmospheric CO2 concentrations below 450ppm.
However, as an aside he did note that if
emission -
rates kept on increasing, the outcome would be different with significant warming in the decades ahead.
Some analysts calculate that to
keep carbon
emissions at today's
rate (ie to
keep the

rate) will cost one to two percent of GNP.
