“…However, in order to perform a high-quality integrated assessment of NETs, a characterization of the different options is needed. A variety of reviews on NET technologies have taken on this task over the years (Smith et al 2016a, National Academy of Sciences 2015, Caldecott et al 2015, Lenton 2014, McGlashan et al 2012, McLaren 2012, Vaughan and Lenton 2011, The Royal Society 2009. From the approximately 3000 articles on NET technologies and measures identified by Minx et al (2017), more than 200 are classified as review articles.…”

Artificial removal of CO 2 from the atmosphere (also referred to as negative emissions) has been proposed as a means to restore the climate system to a desirable state, should the impacts of climate change become 'dangerous'. Here we explore whether negative emissions are indeed effective in reversing climate change on human timescales, given the potentially counteracting effect of natural carbon sinks and the inertia of the climate system. We designed a range of CO 2 emission scenarios, which follow a gradual transition to a zero-carbon energy system and entail implementation of various amounts of net-negative emissions at technologically plausible rates. These scenarios are used to force an Earth System Model of intermediate complexity. Results suggest that while it is possible to revert to a desired level of warming (e.g. 2°C above pre-industrial) after different levels of overshoot, thermosteric sea level rise is not reversible for at least several centuries, even under assumption of large amounts of negative CO 2 emissions. During the net-negative emission phase, artificial CO 2 removal is opposed by CO 2 outgassing from natural carbon sinks, with the efficiency of CO 2 removal-here defined as the drop in atmospheric CO 2 per unit negative emission-decreasing with the total amount of negative emissions.

Assessing the Feasibility of Global Long-Term Mitigation Scenarios

et al. 2017

This study explores the critical notion of how feasible it is to achieve long-term mitigation goals to limit global temperature change. It uses a model inter-comparison of three integrated assessment models (TIAM-Grantham, MESSAGE-GLOBIOM and WITCH) harmonized for socio-economic growth drivers using one of the new shared socio-economic pathways (SSP2), to analyse multiple mitigation scenarios aimed at different temperature changes in 2100, in order to assess the model outputs against a range of indicators developed so as to systematically compare the feasibility across scenarios. These indicators include mitigation costs and carbon prices, rates of emissions reductions and energy efficiency improvements, rates of deployment of key low-carbon technologies, reliance on negative emissions, and stranding of power generation assets. The results highlight how much more challenging the 2 • C goal is, when compared to the 2.5-4 • C goals, across virtually all measures of feasibility. Any delay in mitigation or limitation in technology options also renders the 2 • C goal much less feasible across the economic and technical dimensions explored. Finally, a sensitivity analysis indicates that aiming for less than 2 • C is even less plausible, with significantly higher mitigation costs and faster carbon price increases, significantly faster decarbonization and zero-carbon technology deployment rates, earlier occurrence of very significant carbon capture and earlier onset of global net negative emissions. Such a systematic analysis allows a more in-depth consideration of what realistic level of long-term temperature changes can be achieved and what adaptation strategies are therefore required.
