Bad science and good intentions prevent effective climate action (


Even if all emissions stopped tomorrow, current committed warming will raise global temperatures by 2°C –5°C above pre-industrial levels by 2100 (Cheng et al., 2022; Huntingford et al., 2020; von Schuckmann et al., 2020; Zhou et al., 2021; Hansen et al., 2023). These are massive, long-term problems: the energy imbalance caused by elevated GHG concentrations will continue to drive warming and sea level rise for centuries to millennia (Wadhams, 2016).
