I-acidification yoLwandle i-Arctic isongela izakhamuzi zayo

I-Arctic Ocean

Njengomphumela wokufudumala kwembulunga yonke, izilwandle seziqala ukuba ne-asidi, okubeka engcupheni ukusinda kwezinkulungwane zezinhlobo zasolwandle. Le nqubo isivele ifinyelela entshonalanga ye-Arctic Ocean, okungathinta izimbaza nezinye izilwane abahlali abathembele kuzo ngokocwaningo olwenziwe yi-NOAA nabanye abahlanganyeli, futhi lwashicilelwa kumagazini i-Nature Climate Change.

Lolu cwaningo olusha lukhombisa ukuthi phakathi konyaka we-1990 nowe-2010, ukujula kwamanzi ane-asidi kukhuphukile kusuka cishe kumamitha angama-99 ngaphansi kobuso kuya ngaphezu kwamamitha angama-244.

Njengoba ulwandle lumunca isikhutha, amanzi aba yi-asidi. Ngokwenza njalo, izilwane ezingamagobolondo ezihlala kuyo, njenge-shellfish noma iminenke yasolwandle, azikwazi ukwakha "izihlangu" zazo njengoba kufanele; ukuze ngokuhamba kwesikhathi banciphe. Futhi, njengoba buthaka, Abantu abahlala e-Arctic bazoba nenkinga yokuthola ukudla.

Ngokusho kombhali-ndawonye uWei-Jun Cai wase-University of Delaware, "I-Arctic Ocean ilulwandle lokuqala ukubona ukwanda okusheshayo nokwanda okukhulu kwe-acidification, okungenani kabili ngokuphindwe kabili kunalokho okubonwa olwandle iPacific noma i-Atlantic".

Ishadi Lokuqinisa i-Arctic Ocean

Ukuhlaziywa kwedatha ye-Arctic Ocean kanye nemodeli yokulingisa kukhombisile lokho ukwanda kokugeleza kwamanzi kusuka ePacific kuya e-Arctic phakathi nobusika, kuqhutshwa ngamaphethini wokujikeleza neqhwa lasolwandle ehlobo, ngokuyinhloko kubhekele ukunwetshwa kwe-Arctic acification.

Eminyakeni yamuva nje, ukuncibilika kweqhwa olwandle kuye kwavumela amanzi amaningi avela ePacific ukuba agelezele olwandle i-Arctic futhi anqwabelene, andise amazinga asevele aphezulu e-carbon dioxide. Kodwa-ke, i-pH yamanzi e-arctic iyancipha.
