Vatsvaguriri vakatarisa kuRui-Namur Island paKwajalein Atoll muRepublic yeMarshall Islands (inoratidzwa) yekudzidza kwavo saiti, kwakaitika kubva munaNovember 2013 kusvika Chivabvu 2015 & Nyanzvi dzinoyambira kuti matsime emvura matsva pazvitsuwa zvePacific neIndia makungwa, senge avo veMarshall Islands (pikicha) vachakanganiswa nekusanduka kwemamiriro ekunze zvekuti vazhinji havachabatsira vanhu
tudy co-munyori Dr Stephen Gingerich, nyanzvi yeUSGS hydrologist, akati: 'Zviitiko zvepamusoro zvinowanzo guma nemvura yemunyu ine munyu ichipinda muvhu nekusvibisa iyo yemvura yemvura yakachena. 'Kunaya kwemvura mumashure megore hakuna kukwana kuburitsa mvura yemunyu nekuzorodza kupihwa mvura kwechitsuwa mhepo dutu regore rinouya risati rasvika dzichidzokorora zviitiko zvepamusoro.' Iyo Republic yeMarshall Islands ine zvinopfuura chiuru zana nezviwi zvakaderera pazvitsuwa makumi maviri nemapfumbamwe, uye inogara mazana ezviuru zvevanhu. Mahombekombe egungwa ari kukwira, iine akanyanya mwero munzvimbo dzinopisa, uko zviuru zvemakorari akadzika atoll zviwi zviripo.

- Researchers focused on Roi-Namur Island on Kwajalein Atoll in the Republic of the Marshall Islands (pictured) for their site study, which took place from November 2013 to May 2015 & Experts warn that freshwater reserves on atolls in the Pacific and Indian oceans, like those of the Marshall Islands (pictured) will be so damaged by climate change that many will no longer support humans.
- Researchers from the US Geological Survey (USGS) and the University of Hawaii at Mānoa focused on Roi-Namur Island on Kwajalein Atoll in the Republic of the Marshall Islands for their site study, which took place from November 2013 to May 2015.
- Researchers said that the new findings have relevance not only to the Marshall Islands, but also to those in the Caroline, Cook, Gilbert, Line, Society and Spratly Islands as well as the Maldives, Seychelles, and Northwestern Hawaiian Islands.
