A recent study critiques the overreliance on natural carbon sinks like oceans and forests as part of climate change mitigation strategies. Researchers argue that this approach enables countries to claim net-zero emissions without actually reducing their carbon output. They emphasize that natural sinks can be unstable and affected by climate change, leading to potential miscalculations in emissions reduction goals. The study advocates for a shift towards ‘geological net-zero,’ emphasizing the need for direct emissions removal and long-term storage of carbon underground.
