"King Tides:" Igagasi lekusasa?

Phakamisa isandla sakho uma uzwile igama elithi “king tide.” Phakamisa isandla sakho uma igama likuthuma ukuphuthuma kumashadi ahamba ngamagagasi engxenyeni yakho yogu. Phakamisa isandla sakho uma kusho ukuthi uzoshintsha uhambo lwakho lohambo lwansuku zonke ukuze ungangeni ezindaweni ezigcwele izikhukhula ngoba namuhla kuzobe kune “king tide”.

I-King tide ayilona igama lesayensi elisemthethweni. Igama elivamile elisetshenziswa kakhulu ukuchaza ikakhulukazi amagagasi aphezulu—njengalawo avela lapho kukhona ukuqondana nelanga nenyanga. Ama-King tides awawona ngokwawo uphawu lokushintsha kwesimo sezulu, kodwa, njengewebhusayithi ye-Australian Green Cross's “Fakaza King Tides” ithi, “Zisinikeza ukubuka kuqala kokuthi amazinga olwandle aphezulu angabukeka kanjani. Ukuphakama kwangempela okufinyelelwa yi-king tide kuzoncika esimweni sezulu sendawo nezimo zolwandle ngalolo suku.”

Emashumini eminyaka adlule, amagagasi aphezulu ikakhulukazi ayeyilukuluku—cishe kwaba yindida uma ephazamisa isigqi semvelo sokuphila ezindaweni ezinamagagasi. Emhlabeni jikelele kule minyaka eyishumi edlule, ama-king tides aya ngokuya ehlotshaniswa nemigwaqo egcwele izikhukhula namabhizinisi emiphakathini egudle ugu. Uma kwenzeka ngesikhathi esifanayo neziphepho ezinkulu, izikhukhula zingasakazeka kakhulu futhi zilimaze kokubili ingqalasizinda eyakhiwe abantu neyemvelo.

Futhi ama-king tides adala zonke izinhlobo zokunaka ngenxa yokukhuphuka kwezinga lolwandle. Isibonelo, i-University of Washington's Department of Ecology iphinde ikhuthaze ukuzibandakanya kwezakhamizi ekuqapheni umthelela wamagagasi aphezulu ngokusebenzisa Isinyathelo sesithombe saseWashington King Tide.

Ingoma yenkosi kule nyanga ihambisana nokukhishwa kwentsha umbiko ovela ku-Union of Concerned Scientists ehlinzeka ngezibikezelo ezintsha zezikhukhula ngenxa yokukhuphuka kwezinga lolwandle; imvamisa yemicimbi enjalo ikhula ngokwesibonelo ibe ngaphezu kwama-400 ngonyaka eWashington, DC nase-Alexandria eduze ne-Potomac ehamba phambili maphakathi nekhulunyaka. Imiphakathi kulo lonke ugu lwe-Atlantic Coast kungenzeka ibone ukwanda okumangazayo.

I-Miami Beach isingathe uMphathi we-EPA u-Gina McCarthy, izikhulu zendawo nezifundazwe, kanye nethimba elikhethekile lekhongolose eliholwa nguSenator Bill Nelson kanye nozakwabo baseRhode Island Senator Sheldon Whitehouse ukuzobukela ukuhlolwa kokuqala kohlelo olusha lokulawulwa kwamanzi olwenzelwe ukunciphisa izikhukhula. lokho kuphazamise abagibeli, abanikazi bamabhizinisi, namanye amalungu omphakathi. I I-Miami Herald ibike ukuthi, “Imali engu-$15 million esetshenzisiwe kuze kube manje iyingxenyana yokuqala yezigidi ezingu-500 zamaRandi idolobha elihlela ukuyisebenzisa phakathi neminyaka emihlanu ezayo kumaphampu angu-58 phezulu naphansi oGwini. UMnyango Wezokuthutha waseFlorida uhlela ukufaka amaphampu emigwaqweni engu-10 no-14 kanye naku-Alton Road...Amasistimu amaphampu amasha axhunywe nengqalasizinda entsha yokukhipha amanzi ngaphansi kwe-Alton, ngakho izimo kulindeleke ukuthi zibe ngcono lapho, futhi...Abaholi bedolobha bathemba ukuthi bazokwenza kanjalo. inikeza impumuzo iminyaka engu-30 kuya kwengu-40, kodwa bonke bayavuma ukuthi lelisu lesikhathi eside kuyodingeka lihlanganise nokulungiswa kabusha kwekhodi yokwakha ukuze kwakhiwe izakhiwo eziphakeme ukusuka phansi, ukwenza imigwaqo ibe phezulu futhi kwakhiwe udonga lwasolwandle olude.” IMeya uPhilip Levine uthe ingxoxo izoqhubeka iminyaka yokuthi iBeach izolungiswa kanjani kahle ngamanzi akhuphukayo.”

Ukulindela izindawo ezintsha zezikhukhula, ngisho nezesikhashana, kuyisici esisodwa sokuzivumelanisa nokushintsha kwesimo sezulu. Kubaluleke kakhulu ezindaweni zasemadolobheni lapho amanzi ezikhukhula ehlehlayo angashiyi nje kuphela umonakalo ezakhiweni zabantu, kodwa futhi angathwala ubuthi, udoti, nezinsalela emanzini asogwini kanye nempilo yasolwandle encike kuzo. Ngokusobala, kufanele senze okusemandleni ethu ukuhlela le micimbi kanye nezindlela zokunciphisa lokhu kulimala njengoba eminye imiphakathi isiqala ukwenza. Kubalulekile futhi ukuthi sicabangele izinhlelo zemvelo ekuthuthukiseni amasu ethu okunciphisa endawo, njengoba sisebenzela ukubhekana nezimbangela ezibanzi zokuguquguquka kwesimo sezulu kanye nokukhuphuka kwezinga lolwandle. Izimfunda zotshani basolwandle, imihlume, namaxhaphozi asogwini konke kungasiza ekwehliseni izikhukhula—ngisho noma amanzi anosawoti avamile angase aphazamise amahlathi asogwini nezinye izindawo zokuhlala.

Ngibhale kaningi ngezindlela eziningi okufanele sicabange ngazo ngokushintsha kwesimo sezulu nezilwandle ezinempilo kanye nobudlelwano babantu nolwandle. I-King tides isinikeza isikhumbuzo sokuthi kuningi esingakwenza futhi okufanele sikwenze ukuze sihlangabezane nezinguquko ezingeni lolwandle, amakhemikhali olwandle, nezinga lokushisa lolwandle. Sijoyine.
