Episode 5: Climate impact (ir)reversibility with Debra Roberts

Show notes

In this fifth episode of the nine-part IIASA podcast series with session chair Debra Roberts, we turn to the conference’s fourth theme: Climate Impact (Ir)reversibility. Declining global temperatures after overshoot does not mean local impacts will reverse. Earth system components like oceans and the cryosphere will keep adjusting, reshaping regional climates and exposing communities to new vulnerabilities.

We ask: How is a world after overshoot different from one without it—and for whom? What benefits does warming reversal bring compared to stabilization at peak levels? With a focus on impacts that are irreversible on human timescales and on the socio-economic dynamics of overshoot, this episode explores the implications for justice, equity, and possible social tipping points.
