Kwezani dzanja lanu ngati mwamvapo mawu akuti “mfumu mafunde.” Kwezani dzanja lanu ngati mawuwa akukutumizirani kuthamangira kumadera akunyanja. Kwezani dzanja lanu ngati zikutanthauza kuti musintha ulendo wanu watsiku ndi tsiku kuti musakhale ndi madzi osefukira chifukwa lero pakhala “mafunde amfumu”.

King tide si mawu ovomerezeka asayansi. Ndi mawu omwe amagwiritsidwa ntchito pofotokoza makamaka mafunde-monga omwe amapezeka pamene dzuwa ndi mwezi zimagwirizana. Mafunde a King siwo chizindikiro cha kusintha kwa nyengo, koma, monga tsamba la Australian Green Cross "Umboni wa King Tides” akuti, “Amatipatsa chithunzithunzi cha mmene madzi a m’madzi okwera amaonekera. Kutalika kwenikweni kwa mafunde a mfumu kudzadalira nyengo ya kumaloko ndi nyanja zapanyanja patsikulo.”

Zaka makumi angapo zapitazo, makamaka mafunde amphamvu anali chidwi—pafupifupi chododometsa ngati anasokoneza kaimbidwe kachilengedwe ka moyo m’madera a mafunde. Padziko lonse lapansi m'zaka khumi zapitazi, mafunde a mafumu akugwirizana kwambiri ndi misewu yodzaza madzi ndi mabizinesi m'madera a m'mphepete mwa nyanja. Zikachitika nthawi yomweyo ngati mvula yamkuntho, kusefukira kwamadzi kumatha kufalikira komanso kuwononga zida zomangidwa ndi anthu komanso zachilengedwe.

Ndipo mafunde amphamvu amabweretsa chidwi chamitundu yonse chifukwa cha kukwera kwamadzi am'nyanja. Mwachitsanzo, dipatimenti ya University of Washington's Ecology imalimbikitsanso nzika kuti zizitenga nawo mbali pakuwunika momwe mafunde akukwera kwambiri kudzera m'mafunde ake. Chithunzi cha Washington King Tide.

Mafunde a mfumu mwezi uno akugwirizana ndi kutulutsidwa kwatsopano lipoti lochokera ku Union of Concerned Scientists zomwe zimabweretsa zolosera zatsopano za kusefukira kwa madzi chifukwa cha kukwera kwa madzi a m'nyanja; kuchulukirachulukira kwa zochitika zotere kumachulukira mwachitsanzo kupitilira 400 pachaka ku Washington, DC ndi Alexandria m'mphepete mwa nyanja ya Potomac pofika zaka zapakati. Madera a m'mphepete mwa nyanja ya Atlantic akuyenera kuwonanso chiwonjezeko chachikulu.

Miami Beach ikulandila Woyang'anira EPA Gina McCarthy, akuluakulu aboma ndi aboma, komanso nthumwi zapadera za Congress motsogozedwa ndi Senator Bill Nelson ndi mnzake waku Rhode Island Senator Sheldon Whitehouse kuti awonere mayeso otsegulira njira yatsopano yoyendetsera madzi yopangidwira kuchepetsa kusefukira kwamadzi. zomwe zasokoneza anthu apaulendo, eni mabizinesi, ndi anthu ena ammudzi. The Miami Herald adanena kuti, “Ndalama zokwana madola 15 miliyoni mpaka pano ndi gawo loyamba la ndalama zokwana madola 500 miliyoni zomwe mzindawu udzagwiritse ntchito m’zaka zisanu zikubwerazi pa mapampu 58 okwera ndi pansi pa Gombe. Florida Department of Transportation ikukonzekeranso kukhazikitsa mapampu m'misewu ya 10th ndi 14th ndi Alton Road…Makina atsopano opopera alumikizidwa ndi njira zatsopano zoyendetsera madzi pansi pa Alton, kotero kuti zinthu zikuyembekezeka kukhala bwino kumeneko, komanso…Atsogoleri amizinda akuyembekeza kuti atero. kupereka chithandizo kwa zaka 30 mpaka 40, koma onse akuvomereza kuti njira yanthaŵi yaitali idzaphatikizapo kukonzanso malamulo omanga kuti amange nyumba zotalikirapo, kupanga misewu yokwera ndi kumanga khoma lalitali la nyanja.” Meya a Philip Levine adati zokambiranazi zipitilira zaka zambiri za momwe angakonzekerere Gombe kuti madzi akukwera.

Kuyembekezera madera atsopano osefukira, ngakhale akanthawi kochepa, ndi njira imodzi yokha yosinthira kusintha kwanyengo. Ndikofunikira kwambiri kumadera akumatauni komwe kusefukira kwamadzi kumangosiya kuwonongeka kwa nyumba za anthu, komanso kumatha kunyamula poizoni, zinyalala, ndi zinyalala kupita kumadzi am'mphepete mwa nyanja komanso moyo wapanyanja womwe umadalira iwo. Mwachiwonekere, tiyenera kuchita zomwe tingathe kukonzekera zochitikazi ndi njira zochepetsera zoopsazi monga momwe madera ena akuyamba kuchita. Ndikofunikiranso kuti tiganizire za chilengedwe popanga njira zochepetsera m'dera lathu, ngakhale pamene tikuyesetsa kuthana ndi zomwe zimayambitsa kusintha kwa nyengo ndi kukwera kwa nyanja. Udzu wa m’nyanja, mitengo ya mangrove, ndi madambo a m’mphepete mwa nyanja zonse zingathandize kuchepetsa kusefukira kwa madzi—ngakhale kuti kusefukira kwa madzi amchere nthaŵi zonse kungawononge nkhalango za m’mphepete mwa nyanja ndi malo ena okhalamo.

Ndalemba nthawi zambiri za njira zambiri zomwe tiyenera kuganizira za kusintha kwa nyengo ndi nyanja zathanzi komanso ubale wa anthu ndi nyanja. Mafunde a King amatikumbutsa kuti pali zambiri zomwe tingachite ndipo tiyenera kuchita kuti tikwaniritse kusintha kwa madzi a m'nyanja, momwe zimapangidwira komanso kutentha kwa nyanja. Titsatireni.
