In this episode, Mr. Sun (AI character) & Ms. Remove (AI character) discuss a recent research article that examines the critical role of Carbon Dioxide Removal (CDR) in achieving net-zero emissions goals outlined in the Paris Agreement.

The authors (⁠Cyril Brunner⁠, ⁠Zeke Hausfather⁠ & ⁠Reto Knutti⁠) find that the duration of CO2 storage significantly impacts the effectiveness of CDR, with storage periods under 1000 years proving insufficient to neutralize residual emissions and potentially jeopardizing temperature targets. Using a climate model, they demonstrate that only permanent CO2 storage through CDR achieves true climate neutrality. The study highlights inconsistencies in current net-zero frameworks and emphasizes the need for long-term CO2 storage to avoid future warming. The authors also discuss the potential value of shorter-term CDR for other climate and environmental benefits, but emphasize the crucial need to address the root cause of climate change—accumulating atmospheric CO2.
