Critical Reevaluation of Carbon Storage Estimates

A groundbreaking analysis has emerged, questioning the reliability of previous estimates regarding the planet's capacity to store carbon dioxide (CO2) as a means to combat global warming. Contrary to prior optimistic projections, this study suggests that effective carbon storage—essential for reducing Earth's escalating temperatures—may be significantly more limited than believed.

Startling Findings of the Study

Conducted by researchers from the International Institute for Applied Systems Analysis in Austria, the study published in *Nature* reveals that the most 'prudent' estimates for carbon capture and storage (CCS) could ultimately only lower temperatures by approximately 0.7°C (1.3°F). This drastically pales in comparison to earlier estimates suggesting possible reductions of 5-6°C (9-11°F), challenging the viability of CCS as an effective climate change solution.
