Ka Mark J. Spalding, Mopresidente, The Ocean Foundation

Phahamisa letsoho haeba u utloile lentsoe “king leqhubu.” Phahamisa letsoho la hau haeba lentsoe le etsa hore u potlakele lichate tsa maqhubu sebakeng sa hau sa lebopo. Phahamisa letsoho haeba ho bolela hore u tla fetola leeto la hau la letsatsi le letsatsi hore u se ke ua tsoa libakeng tse tletseng likhohola hobane kajeno ho tla ba le “leqhubu la morena”.

King Tide hase lentsoe la saense la molao. Ke lentsoe le akaretsang le sebelisoang haholo ho hlalosa maqhubu a phahameng haholo—a kang a etsahalang ha letsatsi le khoeli li bapile. Maqhubu a King ha se sesupo sa phetoho ea maemo a leholimo, empa, joalo ka webosaete ea Australian Green Cross "Paki King Tides” e re, “Li re fa ponelo-pele ea hore na leoatle le phahameng le ka shebahala joang. Bophahamo ba sebele bo fihletsoeng ke leqhubu la morena bo tla itšetleha ka boemo ba leholimo ba sebaka seo le maemo a leoatle ka letsatsi leo.”

Lilemong tse mashome tse fetileng, makhubu a phahameng haholo-holo e ne e le bohelehele—hoo e batlang e le pherekano haeba a ne a sitisa morethetho oa tlhaho oa bophelo libakeng tse nang le maqhubu a leoatle. Lefatšeng ka bophara lilemong tse leshome tse fetileng, maqhubu a leoatle a ntse a amahanngoa le literata tse tletseng likhohola le likhoebo tse metseng e lebōpong la leoatle. Ha li etsahala ka nako e le 'ngoe le lifefo tse matla, likhohola li ka ata le ho feta 'me tsa senya mekhoa ea motheo e entsoeng ke batho le ea tlhaho.

'Me li-king tides li hlahisa mefuta eohle ea tlhokomelo ka lebaka la ho phahama ha metsi a leoatle. Mohlala, Lefapha la Ecology la Univesithi ea Washington le boetse le khothaletsa boitlamo ba baahi ho lekola tšusumetso ea maqhubu a phahameng Washington King Tide photo initiative.

Khoeli ea khoeli ena leqhubu le tsamaisana le ho lokolloa ha e ncha tlaleho e tsoang ho Union of Concerned Scientists e fanang ka likhakanyo tse ncha tsa likhohola ka lebaka la ho phahama ha metsi a leoatle; ka makhetlo a mangata a liketsahalo tse joalo a eketseha ka mohlala ho feta 400 ka selemo bakeng sa Washington, DC le Alexandria hammoho le maqhubu a Potomac bohareng ba lekholo la lilemo. Ho ka etsahala hore baahi ba Lebopo la Atlantic ba bone keketseho e makatsang.

The Miami Herald e tlaleha hore, “Lidolara tse limilione tse 15 tse sebelisitsoeng ho fihlela joale ke karolo ea pele ea liranta tse limilione tse 500 tseo toropo e rerang ho li sebelisa nakong ea lilemo tse hlano tse tlang ho lipompo tse 58 holimo le tlaase Lebōpong. Lefapha la Lipalangoang la Florida le boetse le rera ho kenya lipompo literateng tsa 10th le 14th le Alton Road… Lits'ebetso tse ncha tsa lipompo li hokahantsoe le meaho e mecha ea likhoerekhoere tlasa Alton, kahoo maemo a lebelletsoe ho ba betere moo, hape… ho fana ka liphallelo ka lilemo tse 30 ho isa ho tse 40, empa bohle ba lumellana hore leano la nako e telele le tla lokela ho akarelletsa ho nchafatsa melao ea kaho bakeng sa ho haha ​​mehaho e holimo ho tloha fatše, ho etsa litsela tse phahameng le ho haha ​​lerako le lelelele la leoatle.” Ramotse Philip Levine o itse puisano e tla tsoelapele ka lilemo tse ngata mabapi le mokhoa oa ho lokisa Lebōpo bakeng sa metsi a ntseng a phahama.

Ho lebella libaka tse ncha tsa likhohola, esita le tsa nakoana, ke karolo e le 'ngoe feela ea ho ikamahanya le maemo a leholimo. Ho bohlokoa haholo bakeng sa libaka tsa litoropo moo likhohola tse ntseng li khutla li sa tlohele feela tšenyo ea meaho ea batho, empa hape li ka tsamaisa chefo, lithōle le mashala ho ea metsing a lebopo la leoatle le bophelo ba leoatle bo itšetlehileng ka bona. Ho hlakile hore re tlameha ho etsa seo re ka se khonang ho rera liketsahalo tsena le mekhoa ea ho fokotsa likotsi tsena joalo ka ha lichaba tse ling li qala ho li etsa. Ho bohlokoa hape hore re nahane ka litsamaiso tsa tlhaho ho ntlafatseng maano a sebaka sa rona a phokotso, leha re ntse re sebetsa ho rarolla lisosa tse pharaletseng tsa phetoho ea maemo a leholimo le ho phahama ha metsi a leoatle. Makhulo a leoatle, lifate tsa mangrove le libaka tse mongobo tse lebōpong la leoatle kaofela li ka thusa ho fokotsa likhohola—joalokaha ho koaheloa ha metsi a letsoai khafetsa ho ka ama meru e haufi le mabōpo le libaka tse ling tsa bolulo.

Ke ngotse hangata ka mekhoa e mengata eo re lokelang ho nahana ka eona ka phetoho ea maemo a leholimo le maoatle a phetseng hantle le likamano tsa batho le maoatle. Maqhubu a King a re hopotsa hore ho na le lintho tse ngata tseo re ka li etsang le tseo re lokelang ho li etsa ho sebetsana le liphetoho tsa boemo ba leoatle, k'hemistri ea leoatle le mocheso oa leoatle.
