„A New York experiment is part of a commercial race to develop ocean-based technologies to extract carbon dioxide from the atmosphere.[…]This is one of the first field trials of a concept known as ocean alkalinity enhancement — essentially using antacids to help the ocean digest CO2. The two-year experiment is run by Vesta, a start-up climate company based in San Francisco, California, with enthusiastic support from local community leaders. Just metres down the beach, a newly installed welcome plaque proclaims that visitors are about to step onto “the world’s first carbon-removing beach”.“
