Hourglass Climate

The ocean is our greatest resource for capturing hard-to-abate, and historical, carbon emissions - a non-negotiable part of limiting climate warming to 2ºC. Ocean Alkalinity Enhancement (OAE) via alkaline mineral addition has the potential for permanent, gigatonne-scale carbon removal. Targeted, independent, and integrated research that rapidly de-risks the key uncertainties on how to safely deploy mineral-based OAE techniques, while optimizing for fast and efficient carbon removal, is urgently needed to drive climate impact. To do just that, Hourglass brings together an ecosystem of scientists to conduct model, laboratory, and field research for the public benefit.
