stronger warming from higher radiative disequilibrium & weakening carbon sinks, driven by saturated land carbon uptake and the reduced radiative impact of CO2 drawdown at higher background CO2 concentrations. Higher peak warming therefore commits the planet to additional warming, limiting temperature-overshoot reversibility https://www.nature.com/articles/s41558-026-02776-w https://archive.ph/wip/uMgo3 #ClimateChange #UpheavalClimate #ClimateInstability #ClimateReversal #MassAtrocity #pollution #ecology #environment #climate
