“King Tides:” Liza lekamva?

Phakamisa isandla sakho ukuba ukhe weva igama elithi “king tide.” Phakamisa isandla sakho ukuba igama likuthumela uleqa kwiitshathi zolwandle kwindawo yakho yonxweme. Phakamisa isandla sakho ukuba oko kuthetha ukuba uya kutshintsha uhambo lwakho lokuhamba mihla le ukuze ungabikho kwiindawo ezikhukulisekileyo kuba namhlanje kuya kubakho “inkosi”.

King tide ayilogama lesayensi elisemthethweni. Ligama eliqhelekileyo elisetyenziswa ngokubanzi ukuchaza amaza aphakamileyo—njengalawo abakho xa ulungelelwaniso lwelanga nenyanga. Amaza eKing ayingowo mqondiso wokutshintsha kwemozulu, kodwa, njengewebhusayithi yaseOstreliya yeGreen Cross “Ngqina uKumkani uTides” ithi, “Ziyasikrobisa ngendlela anokukhangeleka ngayo amaqondo olwandle aphezulu. Ubude bokwenene obufikelelwa ngamaza okumkani buya kuxhomekeka kwimozulu yasekuhlaleni kunye neemeko zolwandle ngaloo mini.”

Kumashumi eminyaka adlulileyo, ingakumbi amaza aphezulu ibingumdla wokwazi—phantse ibe yinto engaqhelekanga ukuba aye aphazamisa isingqi sendalo sobomi kwiindawo ezinamaza. Ehlabathini lonke kule minyaka ilishumi idluleyo, amaza ookumkani aye anxulunyaniswa nezitrato ezikhukulayo kunye namashishini kwiindawo eziselunxwemeni. Xa zisenzeka ngexesha elinye njengezaqhwithi ezinkulu, izandyondyo zemvula zinokusasazeka ngakumbi kwaye zonakalise kuzo zombini izakhiwo ezakhiwe ngabantu kunye nezendalo.

Kwaye i-king tides ivelisa zonke iintlobo zengqwalasela enkosi ngokunyuka komphakamo wolwandle. Umzekelo, iDyunivesithi yaseWashington iSebe le-Ecology likwakhuthaza ukuzibandakanya kwabemi ekubekeni iliso ifuthe lokunyuka kwamaza aphakamileyo ngokusebenzisa Washington King Tide photo initiative.

Inkosi yale nyanga ihambelana nokukhutshwa kwentsha ingxelo evela kwiManyano yeeNzululwazi eziZixhalabileyo ebonelela ngoqikelelo olutsha lwezandyondyo zemvula ngenxa yokunyuka komphakamo wolwandle; ngokuphindaphindwa kweziganeko ezinje zinyuka ngokomzekelo ukuya ngaphezulu kwama-400 ngonyaka eWashington, DC naseAlexandria ecaleni kolwandle lwePotomac phakathi kwinkulungwane. Uluntu olujikeleze lonke unxweme lweAtlantiki lunokubona ukwanda okumangalisayo ngokunjalo.

I-Miami Beach isingathe uMphathi we-EPA uGina McCarthy, amagosa asekhaya kunye nakarhulumente, kunye negqiza elikhethekileyo lenkongolo elikhokelwa nguSenator uBill Nelson kunye nogxa wakhe ovela kwiSenator yaseRhode Island uSheldon Whitehouse ukubukela uvavanyo lokusungulwa kwenkqubo entsha yolawulo lwamanzi eyenzelwe ukunciphisa izantyalantyala zemvula. eye yaphazamisa abakhweli, abanini bamashishini, kunye nabanye abantu basekuhlaleni. I UMiami Herald uxele ukuba, “I-15 yezigidi zeerandi ezisetyenzisiweyo ukuza kuthi ga ngoku liqhezu lokuqala le-500 yezigidi zeedola isixeko esiceba ukuchitha kule minyaka mihlanu izayo kwiimpompo ezingama-58 phezulu nasezantsi eLwandle. Isebe lezoThutho laseFlorida likwaceba ukufaka iimpompo kwizitrato ze-10 kunye ne-14 kunye ne-Alton Road…Iinkqubo zempompo ezitsha ziqhagamshelwe kwiziseko ezitsha zokuhambisa amanzi phantsi kwe-Alton, ngoko ke iimeko zilindeleke ukuba zibe ngcono apho, ... anikele isiqabu kangangeminyaka engama-30 ukusa kwengama-40, kodwa bonke bayavumelana ukuba eli cebo lexesha elide liya kuquka ukulungiswa ngokutsha kwemigaqo yokwakha ukuze kwakhiwe izakhiwo eziphakamileyo ukusuka emhlabeni, ukwenza iindlela zibe phezulu nokwakha udonga lolwandle olude.” USodolophu uPhilip Levine uthe incoko iza kuqhubeka iminyaka malunga nendlela yokulungisa uLwandle lokunyuka kwamanzi.

Ukulindela imimandla emitsha yezikhukula, kwanezexeshana, yenye nje into yokuqhelana nokutshintsha kwemozulu. Kubaluleke kakhulu kwimimandla yasezidolophini apho ukuhla kwamanzi ezikhukula kungashiyi nje umonakalo kwizakhiwo zabantu, kodwa kunokuthwala ityhefu, inkunkuma, kunye nentlenga kumanzi onxweme kunye nobomi bolwandle obuxhomekeke kubo. Ngokucacileyo, kufuneka senze okusemandleni ethu ukucwangcisa ezi ziganeko kunye neendlela zokunciphisa lo monakalo njengoko uluntu luqala ukwenza. Kukwabalulekile ukuba sithathele ingqalelo iinkqubo zendalo ekuphuhliseni izicwangciso-qhinga zethu zasekhaya zokunciphisa, nanjengoko sisebenzela ukujongana noonobangela ababanzi bokutshintsha kwemozulu kunye nokunyuka komgangatho wolwandle. Amadlelo engca yolwandle, iimangrove, kunye nemigxobhozo eselunxwemeni zonke zinokunceda ukunciphisa izikhukula—nanjengokuba amanzi etyuwa ehlala efukame enokuchaphazela kakubi amahlathi aselunxwemeni kunye nezinye iindawo zokuhlala.

Ndibhale rhoqo malunga neendlela ezininzi ekufuneka sicinge ngazo malunga nokutshintsha kwemozulu kunye neelwandle ezisempilweni kunye nobudlelwane bomntu nolwandle. Amanzi oKumkani asinika isikhumbuzo sokuba kuninzi esinokukwenza kwaye kufuneka sikwenze ukuhlangabezana nokutshintsha kwinqanaba lolwandle, i-chemistry yolwandle kunye nobushushu bolwandle. Dibana nathi.
