He did flag that he was using RCP8.5 projections, which are the highest emissions trajectory of the 4 scenarios developed for AR5 (comparable to A2 scenario in IPCC AR4, which has the highest CO2 emissions in the near - term if I understand it correctly).
The future concentrations of LLGHGs and the anthropogenic emissions of sulphur dioxide (SO2), a chemical precursor of sulphate aerosol, are obtained from several scenarios considered representative of low, medium and high emission trajectories.

«Lower emissions» are in line with Paris agreement targets; «higher emissions» represent current, business - as - usual trajectories.
To investigate how different climate trajectories might influence climate change vulnerability, we assessed species using high (A2), moderate (A1B) and low (B2) IPCC SRES emissions scenarios for 2050 and 2090 [20](Figure 4; Supporting Methods in Supporting Information S1).

Their notion is to have a «Plan C» if emissions trajectories are not bent downward and the higher end of warming projections comes to pass.
Indeed, his core objection appears to be with technology fixes in general, or the conviction that any bit of technological derring - do — be it a high - efficiency photovoltaic cell or a low - emissions vehicle — will be sufficient to nudge the planet from unpleasant trajectories like global warming.
In the case of RCPs, the initial idea was to posit just an emission trajectory, which could potentially be produced by a variety of socioeconomic developments (higher or lower pop growth, higher or lower GDP growth, different combinations of energy sources).
• Kyoto Protocol • EU ETS • Australian CO2 tax and ETS • Mandating and heavily subsidising ($ / TWh delivered) renewable energy • Masses of inappropriate regulations that have inhibited the development of nuclear power, made it perhaps five times more expensive now than it should be, slowed its development, slowed its roll out, caused global CO2 emissions to be 10 % to 20 % higher now than they would otherwise have been, meaning we are on a much slower trajectory to reduce emissions than we would be and, most importantly, we are locked in to fossil fuel electricity generation that causes 10 to 100 times more fatalities per TWh than would be the case if we allowed nuclear to develop (or perhaps 1000 times according to this: http://nextbigfuture.com/2011/03/deaths-per-twh-by-energy-source.html • Making building regulations that effectively prevent people from selling, refurbishing or updating their houses if they are close to sea level (the damage to property values and to property owners» life savings is enormous as many examples in Australia are already demonstrating.
While the imposition of such a high price on carbon emissions is outside the realm of short - term political feasibility, a price of that magnitude is not required to engender a large change in emissions trajectory.
The sources of uncertainty are many, including the trajectory of greenhouse gas emissions in the future, their conversion into atmospheric concentrations, the range of responses of various climate models to a given radiative forcing and the method of constructing high resolution information from global climate model outputs (Pittock, 1995; see Figure 13.2).
Given current emissions trajectories, there is a chance that the temperature increase by 2100 could be near 6oC.21 The last time Earth exhibited a global mean temperature that high, what are now sagebrush grasslands in the southwestern Wyoming and Utah were covered by subtropical, closed canopy forests interspersed with open woodlands (Townsend et al., 2010), reminiscent of subtropical areas in Central America today.
If the world continues along a high - emissions trajectory, spatial shifts will occur by mid-21st century.
Recent observations confirm that, given high rates of observed emissions, the worst - case IPCC scenario trajectories (or even worse) are being realised.
Real - world CO2 emissions have tracked the high end of earlier emissions scenarios [105], and until the currently wealthy countries can produce a large decline in their own emissions per capita, it is dubious to project that emissions per capita in the less developed countries will not continue on a trajectory up to the levels of currently wealthy countries.16
