Ngenxa yokunyuka kwamaqondo obushushu emhlabeni, iilwandle ziqala ukuba neasidi, zibeka emngciphekweni ukusinda kwamawaka ezilwanyana. Le nkqubo sele ifikelela kuLwandlekazi lweArctic olusentshona, ezinokuthi zichaphazele i-shellfish kunye nezinye izilwanyana abahlali abaxhomekeke kuzo ngokophando olwenziwe yi-NOAA kunye nabanye abasebenzisanayo, kwaye yapapashwa kwiphephancwadi Utshintsho lwemozulu.
Olu phando lutsha lubonisa ukuba phakathi kweminyaka ye-1990 kunye ne-2010, ubunzulu bamanzi eneasidi bunyukile ukusuka malunga neemitha ezingama-99 ngaphantsi komhlaba ukuya ngaphezulu kweemitha ezingama-244.
Njengokuba ulwandle lutsala ikharbhon diokside, amanzi aba asidi. Ngokwenza njalo, izilwanyana zeqokobhe ezihlala kuyo, ezinje ngeembaza okanye iminenke yolwandle, azinakho ukwakha "amakhaka" abo njengoko kufanele; ixesha lihamba buthathaka. Kwaye, njengoko besiba buthathaka, Abantu abahlala eArctic baya kuba nengxaki yokufumana ukutya.
Ngokombhali-mbhali u-Wei-Jun Cai weYunivesithi yaseDelaware, "i-Arctic Ocean lulwandle lokuqala ukubona ukunyuka okukhawulezileyo kunye nokwandayo kwe-acidification, ubuncinci ngokukhawuleza okukhawulezayo kunoko kubonwe kulwandlekazi lwePasifiki okanye lweAtlantic».
Umfanekiso-UTammy Beeson, kwiDyunivesithi yaseDelaware
Uhlalutyo lwedatha yeArctic yolwandle kunye neemodeli zokulinganisa zibonise ukuba ukwanda kokuhamba kwamanzi okusuka kwiPasifiki ukuya kwiArctic ebusika, kuqhutywa ziipatheni zokujikeleza kunye nomkhenkce wolwandle ehlotyeni, ikakhulu inoxanduva lokwanda kweActictic acification.
Kwiminyaka yakutshanje, ukunyibilika komkhenkce wolwandle kuye kwavumela amanzi amaninzi avela kwiPasifiki ukuba angene kuLwandlekazi lweArctic aze aqokelele, esonyusa amanqanaba aphezulu eecarbon dioxide. Nangona kunjalo, i-pH yamanzi arctic iyancipha.
