英文摘要The ocean has absorbed 25% of anthropogenic carbon dioxide emissions over the past 40 years, effectively slowing atmospheric carbon dioxide growth but causing ocean acidification. As acidification intensifies, the seawater absorption capacity for carbon dioxide will decline. While the Revelle factor has been used to assess carbon dioxide absorption, it becomes inapplicable at pH < 7.5. Here, we propose a new factor, gamma(CO2), to better measure the absorption capacity for carbon dioxide and acidification. gamma(CO2) decreases with increased partial pressure of carbon dioxide and decreased pH, indicating reduced absorption capacity and intensified acidification. In 2020, global surface ocean gamma(CO2) was 15.50 +/- 0.21, a 13% decline since 1992. Projections under SSP5-8.5 anticipate an average gamma(CO2) of 4.72 by 2100, with 61.5% of global ocean regions below the critical threshold of gamma(CO2) = 3.0, potentially harming aragonite-based organisms.
