Sezvazvinoitika, anthropogenic zviitiko zvakawedzera zvishoma nezvishoma kabhoni dhayokisaidhi zvemukati mumhepo; anenge 30-40% yeakawedzerwa CO2 inotorwa nemakungwa, ichigadzira carbonic acid uye kudzikisa pH (ikozvino pazasi 8.1) kuburikidza nechiitiko chinonzi ocean acidification. Iyo pH inotarisirwa kusvika 7.7 (inomiririra 3-kuwedzera kwehydrogen ion kusungwa) panosvika gore ra2100, inova shanduko yakakosha muzana remakore. Chimwe chinhu chakakosha pakuumbwa kwe skeletal zvinhu mumhuka dzegungwa ndeye calcium, asi calcium carbonate inova yakanyungudika nekumanikidza, saka kabhoni uye skeletons inonyungudika pasi pekudzika kwayo. Calcium carbonate inova zvakare yakakosha pa pH yakaderera, saka kuwedzerwa kweacidification yegungwa ingangodaro ine zvakadzika mhedzisiro pamakungwa, ichigadzira carbonic acid uye ichideredza pH (ikozvino pazasi 8.1) kuburikidza nechiitiko chinonzi ocean acidification. Mubvunzo unotarisirwa kuti unosvika ku7.7 (inomiririra kuwedzera kwe3 mukumanikidzwa kwehydrogen ion) pan
