The growing interest in temporary carbon dioxide removal (CDR) reflects concerns over the feasibility and cost-effectiveness of permanent solutions. However, efforts to integrate temporary CDR into climate policies have relied on flawed equivalency assumptions between temporary and permanent CDR that contradict physical climate science: temporary CDR cannot fully offset CO₂ emissions as permanent CDR can. Instead, the authors demonstrate that temporary CDR provides an effective mechanism for compensating non-CO₂ climate forcers.
