Abstract

Global warming is accelerating, yet current climate strategies centred on emissions reduction and carbon removal are unlikely to prevent temperatures from crossing dangerous tipping points. Although essential, these approaches operate too slowly to counter near-term warming driven by Earth’s growing energy imbalance, weakening carbon sinks, and amplifying climate feedbacks. This mismatch reflects systemic shortcomings in climate risk assessment that underestimate nonlinear risks and the escalating costs of delay. We argue that climate stabilisation should be treated as a risk-management challenge rather than an incremental policy process. This requires explicit comparison of intervention risks with those of continued warming. We outline a comparative risk–risk framework that integrates mitigation, carbon removal, and cooling interventions, and suggests that a viable strategy may require combining rapid decarbonisation and expanded carbon removal with carefully governed cooling interventions to limit near-term warming. Without aligning response timelines with accelerating climate threats, the likelihood of irreversible Earth-system disruption will continue to grow.
