When we design the architecture for the next 10 or 20 years that means today when we discuss that, we encourage developed countries to consider their cumulative emissions as a total and then to take more responsibility.

Thus, two models with the same level of cumulative total anthropogenic CO2 emissions may reach different atmospheric CO2 concentrations (see Smith and Edmonds 2006).

For consistency, we approximate cumulative emissions through 2015 as 560 GtC based on historical values and forecasts under RCP 8.5 (21, 22); for a special case we add 199 GtC to this total to represent the future expectation of emissions already implicit in the current global energy infrastructure (23).

The idea of a «carbon budget» that ties an amount of future warming to a total amount of CO2 emissions is based on a strong relationship between cumulative emissions and temperatures in climate models.

They could cut cumulative carbon dioxide emissions by 34 billion metric tons, more than the total emissions from fossil fuels in this country over six years.

Consider two emission pathways, both with a cumulative total of 1 TtC, but one with a decaying emissions floor, and one with no emissions floor: the pathway without an emissions floor will cause a temperature peak earlier than the pathway with the decaying floor, as the emissions floor causes emissions to be emitted over a longer time period.

When the Total GHG emissions from Annex A sources is selected as the category, the list contains the five years of the first commitment period of the Kyoto Protocol, from 2008 to 2012 and, in addition, «Cumulative».

In figure 3b, at the upper end of the curve, where cumulative totals are large, the existence of an emissions floor seems to make little difference to the peak temperature.

This occurs because the cumulative totals include contributions for portions of the emissions floor that are emitted after the time of peak warming, which can have no effect on peak warming, as illustrated by the green curves in figure 1.

If the cumulative emissions over the duration of the floor are a large fraction of the cumulative total, then the level of the floor is a crucial determinant of peak warming.

The yellow emission pathway has a higher cumulative total than the green one, when integrated to the time when temperatures peak.

We also find that, for large cumulative totals in particular, cumulative metrics based on integrations over smaller time periods, such as 2010 — 2050, do not correlate with peak warming as well as cumulative emissions to a given date near the time of peak warming.

As in Allen et al. [20], this actually forces the many potential emission pathways considered here, which have the same cumulative total, to cross around the middle of the twenty - first century.

In each panel, we plot likelihood profiles over each other for every emission pathway with a cumulative total from 1750 to 2200 within 1 % of the stated cumulative total.

That's because CO2 takes a long time to scrub from atmosphere, so, if they are any emissions at all, this cumulative amount keeps building up, even if only 30 % of total emissions remain in atmosphere.

Peak warming for different cumulative totals and different emissions floors.

Cumulative emissions to 2000 are approximately 0.5 TtC, and a 1.5 GtC yr − 1 emissions floor between 2000 and 2200 has a cumulative total of 0.3 TtC, which leaves only 0.2 TtC remaining if the pathways are to have a cumulative totalCumulative emissions to 2000 are approximately 0.5 TtC, and a 1.5 GtC yr − 1 emissions floor between 2000 and 2200 has a cumulative total of 0.3 TtC, which leaves only 0.2 TtC remaining if the pathways are to have a cumulative totalcumulative total of 0.3 TtC, which leaves only 0.2 TtC remaining if the pathways are to have a cumulative totalcumulative total of 1 TtC.

For the decaying emissions floor in particular, the floor will have decayed to near zero by the time that Ea (t) = FD (t), as the pathway will reach the floor at a later time than it would have if it had a smaller cumulative total.

We note that figure 4c only contains three likelihood profiles, as we only consider three emission pathways with a hard emissions floor and a cumulative total to 2200 of within 1 per cent of 1 TtC.

Despite this higher cumulative total, the green curve has a higher peak warming than the yellow curve because its emissions are put into the atmosphere over a shorter time period.

For a given peak rate of warming, and hence for a given peak emissions rate, pathways with a lower cumulative total or lower emissions in a given year must have a faster rate of decline after the peak.

This is because the fraction of the cumulative total that is part of the emissions curve is much larger than the fraction that is in the emissions floor.

The difference between the harmonized and unharmonized scenarios for cumulative emissions over the 2000 — 2050 period in total CO2 equivalent emissions is expected to be 1 to 2 %, except for the RCP6 scenario, which has a difference of 5 % (Meinshausen et al. 2011b).

Hohne said these six countries make up roughly two - thirds of the developing world emissions, which are more than half of the global total; include everybody and you get a 16 percent reduction in cumulative emissions from the developing world.

Wasdell said that the draft submitted by scientists contained a metric projecting cumulative total anthropogenic carbon dioxide emissions, on the basis of which a «carbon budget» was estimated — the quantity of carbon that could be safely emitted without breaching the 2 degrees Celsius limit to avoid dangerous global warming.

I am not sure I get how you arrived at this: «During this period, anthropogenic CO2 emissions amounted to about 20 % of the total CO2 emissions» I suspect you may be forgetting that the emissions are cumulative, so even a flat blue line would go with a rising orange one.

For that reason one more sensitivity has been added to the palette: TCRE (Transient Climate Response to Emissions), which relates the peak temperature to the cumulative total of eEmissions), which relates the peak temperature to the cumulative total of emissionsemissions.
