Centuries of carbon removal may be needed to stop delayed climate damage

Net Zero Won't Be Enough — We May Need Centuries of Carbon Removal

We wrote about this research earlier this week, but it’s worth drilling deeper into what makes these findings so consequential for the carbon removal industry. The core finding from Johannes Bednar’s team at IIASA: reaching net zero doesn’t freeze climate damage in place. Sea levels keep rising. Permafrost keeps thawing. These slow-response systems operate on timescales measured in centuries, not decades — and they don’t stop just because we stopped adding CO₂. ...
