IPCC baseline scenarios have over-projected CO2 emissions and economic growth (2020, neutral): “However, in practice, research often emphasizes low-and high-forcing scenarios, in ways that can give the impression (Hausfather and Peters 2020) that: the high-forcing scenario is business as usual (BAU) or its equivalent, the low-forcing scenario is what can be achieved through mitigation, and…”
Assessing changes in global fire regimes (2023, neutral): “In reality, it is the more extreme warming scenarios that are becoming less likely (Hausfather & Peters, 2020; Lovins et al., 2019).”
RCP8.5 tracks cumulative CO2 emissions (2020, neutral): “5 has been used repeatedly, if somewhat inconsistently and controversially (1, 2, 5).”
Plausible 2005–2050 emissions scenarios project between 2 °C and 3 °C of warming by 2100 (2022, neutral): “…discussion of scenario plausibility and implications for research and policy (e.g. Ritchie and Dowlatabadi 2017, Pielke 2018, O’Neill et al 2020, Schwalm et al 2020, Hausfather and Peters 2020a, 2020b, Burgess et al 2021, Sognnaes et al 2021, Stammer et al 2021, Pielke and Ritchie 2021a, 2021b).”
Acting rapidly to deploy readily available methane mitigation measures by sector can immediately slow global warming (2021, neutral): “While some have argued that this is an unrealistic baseline (e.g. Hausfather and Peters 2020), others assert that RCP8.”
