Profound changes in seawater chemistry are underway as the ocean takes up about one fourth of the anthropogenic CO2 emitted to the atmosphere year-on-year. This phenomenon has emerged as a key issue of global concern in the last fifteen years.
Without the oceans, the CO2 content in the atmosphere would have been much higher and global warming and its consequences more dramatic. But the uptake of man-made CO2 by the oceans results in ocean acidification, often referred to as "the other CO2 problem" alongside global warming.
The OA-ICC works to promote, facilitate and communicate global activities on ocean acidification. It is looking to implement key overarching activities that must be performed at the international level to make the most effective use of the science investment. The OA-ICC serves as a hub bringing together scientists, policy makers, media, schools, the general public and other ocean acidification actors and stakeholders.
