New Zealand’s new government has vowed to explore ‘blue carbon’ options for removing atmospheric CO₂ to meet net zero goals. But first we need a national strategy for this developing field of science.
Can we engineer oceans to store more carbon dioxide in the fight against climate change? A new bill before parliament seeks to regulate such activity, but holds back on research incentives.
Nitrogen-fixing bacteria help tropical phytoplankton absorb carbon dioxide, creating a biological pump in the oceans.
Adding industrial chemicals and natural alkaline minerals could slow climate change, but like other geoengineering proposals, it comes with many complex technical and legal challenges.
