The 1.3 - litre diesel returns up to 72.4 mpg, and its 104g / km CO2
emissions figure means a reasonable 22 % Benefit - in - Kind (BiK) company - car tax rating.
Disappointing economy and
emissions figures mean the Soul will be pricier to run than it could be
Not exact matches
It can't match the PHEV on paper, but its claimed fuel consumption of 53.3 mpg is pretty good for an SUV this size, although its 139g / km CO2
emissions figure still
means a relatively pricey 29 % Benefit - in - Kind (BiK) rating for company - car drivers.
Drivers are rarely able to achieve quoted official fuel economy
figures, and the increased amount of fuel used also
means official
emissions statistics are innacurate too.
However, a change to
emissions testing
meant CO2
figures increased slightly from 1 February 2018, pushing the Prius above the threshold for free entry into the London Congestion Charge Zone.
While this
figure will obviously depend on how you drive the P400e, its 64g / km CO2
emissions figure is fixed, and
means it's by far the cheapest Range Rover Sport for company - car drivers.
The Euro IV compliant unit also offers impressively low carbon dioxide
emissions, with a CO2
figure of just 149g / km for the five - door hatch and 158g / km for the Wagon,
meaning the newcomer will appeal as much to fleets as it will to cost - conscious private buyers.
Figures 1 and 2 of the post are referenced to the year 2000; however, since 2000 the world has been on an anthropogenic
emissions path leading to at least a 5oC
mean global temperature rise by 2100.
According to Greenpeace analysis of the
figures, this
means that China's CO2
emissions declined by 1 - 2 % in 2015.
The most statistics can tell us at present is that there does appear to be a genuine warming trend in
figure A. Whether this trend is the effect of greenhouse gas
emissions or of a natural fluctuation due to some as - yet - undiscovered mechanism can not be determined from an analysis of the global
mean temperature alone.
Figure 4: Projected global
mean surface temperature changes from 1990 to 2100 for the full set of IS92
emission scenarios.
If we were certain that the ensemble
mean warming represents the real climate systemt we could read out from
figure 1c at which cumulative carbon
emission we could expect to cross this threshold.
Carbon and Other Biochemical Cycles: On cumulative fossil fuel
emissions for the 2012 - 2100 period, China, Kenya and Venezuela, opposed by Germany, said presenting
figures for the
means together with the ranges created confusion.
Of the factors examined, CH4
emissions were best predicted by chlorophyll a concentrations (positive correlation, p < 0.001, R2 = 0.50, n = 31); CO2
emissions were best predicted by reported
mean annual precipitation (positive correlation, p = 0.04, R2 = 0.11, n = 33); and N2O
emissions were most strongly related to reservoir NO3 — concentrations (positive correlation, p < 0.001, R2 = 0.49, n = 18, table 3, supplemental
figure S6).
However, it is much easier to
figure out what happens when you add more radiative gases to an atmosphere that already has them: And, the answer is that it increases the IR opacity of the atmosphere, which increases the altitude of the effective radiating level and hence
means the
emission is occurring from a lower - temperature layer, leading to a reduction of
emission that is eventually remedied by the atmosphere heating up so that radiative balance at the top - of - the - atmosphere is restored.
These
figures illustrate the way the probability distribution of future global
mean temperature change under a high -
emissions scenario is linked to different potential changes in temperature and precipitation at a county - level.
For example, the 183
figure which is highlighted in gold
means Mass's 17.1 % electric power as a source of its overall CO2
emissions is 1.83 times higher than Maine's 9.4 % electric power as a source of CO2.
Figure 3: Global
mean temperature measurements (black) and projections based on an IPCC scenario with high
emissions (A2) for a climate sensitivity parameter of 5 °C (upper red) and 2 °C (upper blue).
Shown are the simulated, multi-model
mean responses to (i) the A2
emissions scenario and (ii) an extended B1 scenario, where radiative forcing beyond the year 2100 was kept constant to the 2100 value (all data from Meehl et al., 2007,
Figure 10.4, see also Meehl et al., 2007, Section 10.7).
The
mean emissions of the N American members of the global 10 % are 32 tonnes of carbon per person per year, for the 1 %, the
figure is 86 tonnes.
In any case, again,
figure 3 shows that if we stop all
emissions now (and yes, Jim, that
means completely stop emitting any more CO2, not just stabilize the rate we are emitting at now, unless I'm missing something), with a climate sensitivity of 3 degrees C we will see atmospheric CO2 levels remain at current high levels for centuries.
What I
mean by this question is that climate change poses a real challenge to social change movements because it is gradual, delayed in its effects, and uneven in its impacts.The message that is coming from climate scientists at present, along with climate - hawkish public
figures, is that we still have time to change — that international conferences, evolving public policies, steady but small annual
emissions reductions, could still prove sufficient to keep us within the «safe zone».
This
figure came in 240 % higher than in 2006, resulting partially from a
mean rise in the price of carbon
emissions from $ 4.10 per tonne to $ 6.10 per tonne.
Pre-TAR AOGCM results held at the DDC were included in a model intercomparison across the four SRES
emissions scenarios (B1, B2, A2, and A1FI) of seasonal
mean temperature and precipitation change for thirty - two world regions (Ruosteenoja et al., 2003).9 The inter-model range of changes by the end of the 21st century is summarised in
Figure 2.6 for the A2 scenario, expressed as rates of change per century.
