Advancing ocean alkalinity enhancement to combat climate change

 In response to the urgent need to address global warming, research at McMaster University and the University of Toronto, supported by the Carbon to Sea Initiative, focuses on enhancing ocean alkalinity to balance pH levels and encourage atmospheric CO2 absorption. The process, known as ocean alkalinity enhancement (OAE), involves innovative methods such as bipolar membrane electrodialysis (BMED) to reduce ocean acidity without adding external substances. Despite potential benefits, significant challenges in technology scaling, ecosystem impacts, and economic viability remain. Accelerated support from various sectors is crucial to develop and deploy OAE solutions effectively. (Phys.org)
