recent emissions figures.

The
figure is also about 10 per cent less than the estimate given for China in the most
recent publication of the Global Carbon Project, which updates annually the global carbon
emissions and their implications for future trends.
On the high end,
recent work suggests that 4 feet is plausible.23, 3,6,7,8 In the context of risk - based analysis, some decision makers may wish to use a wider range of scenarios, from 8 inches to 6.6 feet by 2100.10,2 In particular, the high end of these scenarios may be useful for decision makers with a low tolerance for risk (see
Figure 2.26 on global sea level rise).10, 2 Although scientists can not yet assign likelihood to any particular scenario, in general, higher
emissions scenarios that lead to more warming would be expected to lead to higher amounts of sea level rise.
(We use 2012
figures because that is the starting point for what we actually need to accomplish; all

Figure 1 shows
recent emissions (the 1990 — 2009 gray area), our representative 350
emissions pathway (the 2010 — 2050 red area) and, for comparison, a business - as - usual pathway (the dotted black line) that's consistent with the International Energy Agency's standard «reference case» (no new climate policy) projections.
Recent figures suggested
emissions from Chinese coal plants may have peaked last year, while the government in the past few months has announced a series of measures to curtail coal development.
The model uses historical data through the most
recent available
figures, including country - level GDP and population and GHG
emissions from fossil fuels, changes in land use, and other sources.
Changes in CO2
emissions attributed to Kaya Identity factors from 2015 to 2016 compared with the trend from the prior decade: This
figure gives context to the most
recent year ‐ to ‐ year change by comparing it to the average change for key parameters over the previous decade.
Recent research found that natural solutions like improved management of forests, wetlands, grasslands and agricultural lands can remove about 5.6 GtCO2e of carbon per year by 2030 — a
figure equivalent to total global
emissions from agriculture in 2014 — at a cost of less than $ 100 per tonne of carbon.
These
figures do not take into account the
recent long - term energy strategy of the European Union (EU), which proposes that by 2020, EU consumption of renewables will increase to 20 percent of total energy use; the proportion of biofuels used in transport will increase to 10 percent; and EU greenhouse gas
emissions will be reduced to 20 percent below 1990 levels (European Union, 2007).
• Poles to tropics temperature gradient, average temp of tropics over past 540 Ma; and arguably warming may be net - beneficial overall • Quotes from IPCC AR4 WG1 showing that warming would be beneficial for life, not damaging • Quotes from IPCC AR5 WG3 stating (in effect) that the damage functions used for estimating damages are not supported by evidence • Richard Tol's breakdown of economic impacts of GW by sector • Economic damages of climate change — about the IAMs • McKitrick — Social Cost of Carbon much lower than commonly stated • Bias on impacts of GHG
emissions —
Figure 1 is a chart showing 15
recent estimates of SCC — Lewis and Curry, 2015, has the lowest uncertainty range.
Moreover the
recent decline of the yearly increments d (CO2) / dt acknowledged by Francey et al (2013)(
figure 17 - F) and even by James Hansen who say that the Chinese coal
emissions have been immensely beneficial to the plants that are now bigger grow faster and eat more CO2 due to the fertilisation of the air (references in note 19) cast some doubts on those compartment models with many adjustable parameters, models proved to be blatantly wrong by observations as said very politely by Wang et al.: (Xuhui Wang et al: A two-fold increase of carbon cycle sensitivity to tropical temperature variations, Nature, 2014) «Thus, the problems present models have in reproducing the observed response of the carbon cycle to climate variability on interannual timescales may call into question their ability to predict the future evolution of the carbon cycle and its feedbacks to climate»
Commenting on the release of the
emissions figures, Dr Mary Kelly, Director General of the Environmental Protection Agency stated, «the Emissions Trading Scheme is designed to bring about reductions in emissions at least cost, and is seen to play an increasingly important role in assisting European industry implement the type of reductions envisaged in the EU Commission's recent decisions on an overall 20 percent reduction of greenhouse gas emissions in the EU by 2020... While no doubt some of the reduction reflects the economic downturn which began to have significant impact during 2008, nonetheless the overall picture is one of progressive annual GHG emission reduction

The NewScientist.com news service reports some
recent conclusions of the Global Carbon Project: «Far from slowing down, global carbon dioxide
emissions are rising faster than before Though alarming, the
figures confirm expectations.
Center for American ProgressWith other smaller changes in global
emissions projections — including a decrease due to the
recent economic downturn and reduced
emissions from deforestation and loss of peat lands — the high - end abatement path so far from the Copenhagen Accord commitments leaves us only 5 gigatons short of the 44 gigaton goal by 2020 — two - thirds of the reductions needed to achieve climate safety (
