Using seawater to reduce our carbon footprint

Capturing carbon dioxide (CO₂) from seawater to address climate change could be more efficient than existing systems that capture CO₂ from ambient air. Oceans and other surface waters act as large carbon sinks and have absorbed 30% to 40% of CO₂ emissions from human activities since the industrial revolution began. Find out about the chemistry behind this new ocean capture system and it’s potential role in mitigating rising CO₂ levels.
