Zilumba zazing'ono zotentha sizitha kukhalamo mkati mwa zaka 30 chifukwa cha kukwera kwamadzi m'nyanja komanso kusefukira kwamadzi, kafukufuku watsopano akusonyeza. Zilumba kuphatikiza malo opumira tchuthi cha paradiso monga Seychelles ndi Maldives (chithunzi) zitha kukhudzidwa posachedwa 2030, akutero.

- Akatswiri adaphunzira chilumba cha Roi-Namur ku Marshall Islands kuyambira 2013 mpaka 2015
- Gwero lalikulu la madzi akumwa a atolls ndi mvula yomwe imalowa pansi
- Kukwera kwa nyanja kumanenedweratu kuti kumabweretsa madzi anyanja akuipitsa gwero ili
- Izi zikuloseredwa kuti zidzachitika pachaka pakati pa zaka za m'ma 21
- Kukhazikika kwa anthu pazilumba za atoll kumatha kukhala kosatheka pofika 2030 mpaka 2060
Zilumba zazing'ono zotentha zitha kukhala zosakhalamo m'zaka 30 chifukwa cha kukwera kwamadzi m'nyanja komanso kusefukira kwamadzi, kafukufuku watsopano akusonyeza. Akatswiri akuchenjeza kuti malo osungira madzi akumwa a m'nyanja za Pacific ndi Indian adzawonongeka kwambiri ndi kusintha kwa nyengo kuti ambiri sadzathandizanso anthu. Asayansi akulosera kuti malo oti adzagwere adzafikiridwa pakati pa zaka zana lino pomwe madzi apansi panthaka oyenera kumwa adzatheretu. Zilumba kuphatikiza malo opita kutchuthi cha paradiso monga Seychelles ndi Maldives atha kukhudzidwa posachedwa 2030, akutero.
Ofufuza kuchokera ku US Geological Survey (USGS) ndi University of Hawaii ku Mānoa adayang'ana pachilumba cha Roi-Namur pachilumba cha Kwajalein Atoll ku Republic of Marshall Islands kuti aphunzire za masamba awo, zomwe zidachitika kuyambira Novembala 2013 mpaka Meyi 2015. Gwero loyamba Madzi amchere pazilumba za atoll ndi mvula yomwe imalowa pansi ndikukhalabe ngati madzi osanjikiza omwe amayandama pamwamba pamadzi amchere kwambiri. Komabe, kukwera kwamadzi am'madzi kumanenedweratu kuti kumabweretsa madzi amkuntho ndi mafunde ena omwe amakokolola komanso kupitirira zilumba zotsika, zomwe zimadziwika kuti oversh. Izi zimapangitsa kuti madzi amchere pa ma atoll asakhale oyenera kudyedwa ndi anthu.
Akatswiri adagwiritsa ntchito zochitika zosiyanasiyana pakusintha kwanyengo kuti awonetse kukhudzidwa kwakukwera kwamadzi ndi kusefukira kwamadzi m'derali. Asayansi akuneneratu kuti, kutengera kuchuluka kwa mpweya wowonjezera kutentha wapadziko lonse lapansi, zidzakhala zochitika zapachaka kuzilumba zambiri za atoll mkati mwa 21st Century. Kuchepa kwamadzi akumwa pansi kumapangitsa kuti malo okhala azikhala ovuta m'malo ambiri kuyambira mzaka za m'ma 2030 mpaka 2060, akutero. Izi zitha kufuna kusamutsa nzika zakunyumba kapena kusungitsa ndalama zambiri muzinthu zatsopano, ofufuza achenjeza.
Ofufuzawo adayang'ana pachilumba cha Roi-Namur pachilumba cha Kwajalein Atoll ku Republic of the Marshall Islands (chithunzi) kuti aphunzire malo awo, omwe adachitika kuyambira Novembala 2013 mpaka Meyi 2015 & Akatswiri amachenjeza kuti akasungidwe amadzi oyera pazilumba za Pacific ndi Indian, monga zomwe zili ku Marshall Islands (chithunzi) zidzawonongeka kwambiri chifukwa cha kusintha kwa nyengo kwakuti ambiri sadzathandizanso anthu
Wolemba nawo tudy Dr Stephen Gingerich, katswiri wama hydrologist ku USGS, adati: 'Zomwe zimachitika pamwambapa zimachititsa kuti madzi amchere amchere pansi ndikudetsa madzi amadzi abwino. 'Mvula mvula kumapeto kwa chaka siyokwanira kutulutsa madzi amchere ndikutsitsimutsa madzi pachilumbachi mvula yamkuntho yotsatira isanafike ikubwereza zomwe zidachitika.' Republic of the Marshall Islands ili ndi zilumba zoposa 1,100 zotsika pazilumba 29, ndipo ili ndi anthu masauzande ambiri. Madzi a m'nyanja akukwera, ndipo ndi okwera kwambiri kumadera otentha, komwe kuli zilumba zazitali kwambiri zam'madzi za coral. Gululi lati njira yawo itha kukhala yothandizira ma atoll padziko lonse lapansi, ambiri omwe ali ndi mawonekedwe ndi mawonekedwe ofanana - kuphatikiza, pafupifupi, ngakhale kukweza malo otsika.
Ofufuzawo ati zomwe zapezazi zikugwira ntchito osati ku Zilumba za Marshall zokha, komanso kwa zomwe zili ku Caroline, Cook, Gilbert, Line, Society ndi Spratly Islands komanso zilumba za Maldives, Seychelles, ndi Northwestern Hawaiian Islands. Kafukufuku wam'mbuyomu wazolimba pazilumbazi mpaka kunyanja akuyembekezeredwa kuti azikhala ndi zovuta zochepa mpaka kumapeto kwa zaka za m'ma 21st. Koma maphunziro am'mbuyomu sanaganizire zowopsa zowonjezeredwa zomwe zimayendetsedwa ndi mafunde kapena zomwe zimakhudza kupezeka kwa madzi oyera. Wolemba wotsogola Dr Curt Storlazzi, wa USGS, adaonjezeranso kuti: 'Malo oti madzi akumwa azilumba pazilumba zambiri za atoll sadzapezeka sakuyembekezeka kufikira kumapeto kwa zaka za m'ma 21. 'Izi ndizofunikira kuwunika zoopsa zingapo ndikuyika patsogolo zoyesayesa zochepetsera chiopsezo ndikuwonjezera kulimba mtima kwa madera azilumba za atoll padziko lonse lapansi.'

- 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.
