With the emergence of a global climate youth movement, questions of intergenerational justice regarding climate change mitigation have come to the fore. However, a scientific perspective on intergenerational climate impacts is still lacking. Here we show that newborns in 2020 are projected to experience 2–7 times more extreme events globally under current climate pledges than someone born in 1960, using a novel framework that quantifies impacts as they are experienced along a person’s lifetime. Limiting warming to 1.5 ◦ C consistently reduces that burden while still leaving younger generations with unavoidable impacts that are unmatched by those experienced by older generations. Our results provide a scientific basis to understand the position from which younger generations challenge the present shortfall of adequate climate action.
