Several plans are afoot to make ocean based climate interventions without sufficiently studying the impact and risks associated with such interventions. More than 40% of the earth's biodiversity is in deep ocean. Climate interventions such as carbon sequestering or producing renewable energy in the sea are major interventions that require appropriate study and adaptation before adversely affecting the ocean.

A group of international researches, as part of the Deep Ocean Stewardship Initiative's Climate Working Group, are now studying the (potentially irreversible) impact of ocean-based climate interventions.

Highlights:

1. Several lines of evidence led experts to raise substantial concern and call for the need for an integrated research framework to consider deep-sea impacts carefully in mitigation planning.

2. E.g. Hypercapnia, a condition that occurs when the concentration of carbon dioxide in the water exceeds certain thresholds can have negative impacts on marine life and ecosystems.

3. Interventions could add further pressure and threaten the functioning of the diverse systemss, which are essential for the entire planet.

This study results have been published in Science. Before starting deep and irreversible interventions, a deeper study and debate is in order.
