Model structure in observational constraints on transient climate response

Richard J. Millar, Alexander Otto, Piers M. Forster, Jason A. Lowe, William J. Ingram, Myles R. Allen
2015 Climatic Change  
The transient climate response (TCR) is a highly policy-relevant quantity in climate science. We show that recent revisions to TCR in the IPCC 5th Assessment Report have more impact on projections over the next century than revisions to the equilibrium climate sensitivity (ECS). While it is well known that upper bounds on ECS are dependent on model structure, here we show that the same applies to TCR. Our results use observations of the planetary energy budget, updated radiative forcing

We show that global climate models (GCMs) don't sample a region of low TCR and high RWF consistent with observed climate change under all simple models considered. Whether the additional constraints from GCMs are sufficient to rule out these low climate responses is a matter for further research.

Stochastic techno-economic analysis of the production of aviation biofuel from oilseeds

Ana Paula M. M. Diniz, Richard Sargeant, Graeme J. Millar
2018 Biotechnology for Biofuels  
The economic viability of hydrodeoxygenation process using Camelina, Carinata and Jatropha feedstocks for aviation biofuel production was evaluated for two product profiles: (i) maximum diesel production and (ii) maximum jet fuel production (HRJ). Results: Deterministic analysis of Camelina and Carinata diesel facilities returned positive NPVs and IRRs of 25 and 18%, respectively. Stochastic analysis suggested that the probabilities of positive NPVs were 75, 59 and 15%, respectively, for

Sensitivity analysis determined that financial performance was majorly influenced by feedstock and fuel prices. Categories of subsidies to enhance the attractiveness of the projects were studied. Conclusions: Camelina, Carinata and Jatropha plants targeting HRJ required incentives of 0.31, 0.39 and 0.61 US$/L of biofuel produced, respectively, to reduce the probabilities of loss to approximately 30%.

Current fossil fuel infrastructure does not yet commit us to 1.5 °C warming

Christopher J. Smith, Piers M. Forster, Myles Allen, Jan Fuglestvedt, Richard J. Millar, Joeri Rogelj, Kirsten Zickfeld
2019 Nature Communications  
Committed warming describes how much future warming can be expected from historical emissions due to inertia in the climate system. It is usually defined in terms of the level of warming above the present for an abrupt halt of emissions. Owing to socioeconomic constraints, this situation is unlikely, so we focus on the committed warming from present-day fossil fuel assets. Here we show that if carbon-intensive infrastructure is phased out at the end of its design lifetime from the end of 2018,

Delaying mitigation until 2030 considerably reduces the likelihood that 1.5 °C would be attainable even if the rate of fossil fuel retirement was accelerated. Although the challenges laid out by the Paris Agreement are daunting, we indicate 1.5 °C remains possible and is attainable with ambitious and immediate emission reduction across all sectors.

Supplementary Information and Figures from The utility of the historical record for assessing the transient climate response to cumulative emissions

Richard J. Millar, Pierre Friedlingstein
2018 Figshare  
The historical observational record offers a way to constrain the relationship between cumulative carbon dioxide emissions and global mean warming. We use a standard detection and attribution technique, along with observational uncertainties to estimate the all-forcing or 'effective' transient climate response to cumulative emissions (TCREs) from the observational record. Accounting for observational uncertainty and uncertainty in historical non-CO2 radiative forcing gives a best-estimate from

While the best-estimate TCRE lies in the lower half of the IPCC likely range, the high upper bound is associated with the not-ruled-out possibility of a strongly negative aerosol forcing. Earth System Models typically have a higher effective TCRE range when compared like-for-like with the observations over the historical integrations, associated in part with a slight underestimate of diagnosed cumulative emissions relative to the observational best-estimate, a larger ensemble mean-simulated CO2-induced warming and rapid post-2000 non-CO2 warming in some ensemble members.This article is part of the themed issue 'The Paris Agreement: Understanding the physical and social challenges for a warming world of 1.5°C above pre-industrial levels'.
