amazi meza yo kugenzura amazi meza

Bwana Waterman yahoze ari umurinzi wa parike y’igihugu akaba n'umwanditsi wa Atlas ya National Geographic ya Parike y’igihugu. Umugezi wa Noatak wuzuye wuzuye uherereye mu irembo rya kure rya Parike y’igihugu ya Arctique mu majyaruguru y’iburengerazuba bwa Alaska, ugasunika uruzitiro rwacu hepfo no guhuhuta mu muyaga. Inzira y’impongo itwikiriwe n’imisozi ku musozi, kandi ibicu bya cumulus byegeranya hejuru y’ikibaya nk'imbuto zeze. . Ikibaya ni kinini cyane kuburyo ushobora kumva urujijo niba udafite binokula kandi ukagisha inama ikarita kenshi. Kugira ngo nirinde gukubita inkombe z'umugezi, nagombaga kureba ku ruzi rwuzuye imivurungano n'amaso atyaye maze ngashyigikira inkono n'amaboko yombi.Mu gihe imvura ikabije yakuye uruzi kure y'inkombe (kandi bidindiza indege yacu yo mu nyanja iva i Bettles, muri Alaska kugira ngo iminsi itatu), ahantu hose hashobora kuba inkambi yogejwe na sili hanyuma urohama. Imyaka 36 irashize kuva mperuka kuba umuyobozi ku ruzi rwa Noatak.Uyu mwaka, ntabwo nishimiye kwibuka kureremba mu gihugu cy’ishyamba cyatekerezwa, ariko natangajwe n'ukuntu imihindagurikire y’ikirere yahinduye cyane ibyo nari nsanzwe nzi. Nashimishijwe n'ubutayu ubuzima bwanjye bwose kugirango mvugurure mu mwuka, nuko mpitamo Noatak nk'urugendo ruhebuje rwo mu butayu kugira ngo nsangire n'umuhungu wanjye Alistair w'imyaka 15 n'undi muryango.Nanjye ndagerageza guhunga ubushyuhe bwo hejuru ndetse n'amashyamba. umwotsi wumuriro muri Colorado. Ndibwira ko iki kizaba igice cyiza mumajyaruguru ya kure. Natunguwe, ubushyuhe bwari hafi ya dogere 90 Fahrenheit muminsi itatu ikurikiranye.Iyi nyenzi irabyimbye kuburyo butangaje.Twaje hano muri Kanama, twizeye ko ubukonje busanzwe butangira ukwezi buzica igicu cy imibu kizwi.Ariko imihindagurikire y’ikirere imaze igihe kirekire. icyi no gutinza ubukonje, bityo dukeneye inshundura zo mumutwe hamwe nudukoko twangiza udukoko. Jye na Alistair twoga inshuro nyinshi muruzi kugirango dukonje. Iki nigikorwa ntigeze ntekereza mugihe cyingendo nyinshi zerekeza mumajyaruguru ikonje.Ariko mumyaka itandatu ishize, Alaska yagize ibihe bishyushye cyane. Kuva urugendo rwanjye rwa mbere nanyuze muri aya masoko mu 1982, ubushyuhe bwa Arctique bwazamutseho dogere nyinshi Fahrenheit. Muri icyo gihe, twambaraga imbeho mu cyumweru cya mbere Kanama.Nyamara, bidatinze, abahanga batangira kuburira ko Arctique yari ashyushye inshuro ebyiri ugereranyije ku isi.Mu myaka mirongo ishize, iki gice cya Alaska cyibasiwe nubushyuhe budasanzwe n’umuriro. Igihe umuyaga wibasiye ku ya 5 Kanama, ubushyuhe bwaragabanutse kugera kuri dogere zirenga 50, kandi ubwo twavaga mu irembo rya Arctique tukinjira mu kigo cy’igihugu cya Noatak, imvura yongeye kugwa. Ubutayu bwemewe n'amategeko busangiwe na parike zombi burenga miliyoni 13 hegitari, ikagira ahantu hanini hatagira umupaka mu gihugu, ikingira sisitemu nini nini idahinduwe.Ariko urebye igisubizo kidasanzwe cy’imihindagurikire y’ikirere, imiterere ikingiwe n’akarere ntabwo isa nkaho ihumuriza. Imwe muri zo ni ugukonjesha permafrost, ikubiyemo hafi kimwe cya kane cy’isi y’amajyaruguru.Nasobanuriye Alistair ko ubushyuhe bw’isi bwakuye permafrost mu cyuma kizwi cyane. kubitsa byakuruye kandi bisunika imiryango y’ibimera bya kera mu butaka, bihita bikonjeshwa muri permafrost mbere yuko byose byangirika. Kuva intangiriro y’impinduramatwara mu nganda, permafrost yarimo karubone nyinshi kuruta abantu barekuwe. Noneho, ni nkaho epinari ikonjeshejwe ishyirwa ku gikoni.Permafrost yatangiye kubora no gusohora karubone na metani mu kirere byiyongera ku myuka ya parike ikorwa n'abantu yateje ubushyuhe ku isi. Mugihe cyo kuzamuka kwa tundra mu myaka ya za 1980, ibirenge byanjye byakomeje kuba byumye; kuriyi nshuro, twagiye twinika inkweto inshuro nyinshi hanyuma tunyura muri tundra yuzuye amarira ya permafrost.Umusozi uri hejuru nta rubura. Urubura ku irembo rya Pole y'Amajyaruguru hafi yabuze umwaka wose. Nkuko ubushakashatsi bwakozwe, kuri kare 34 kilometero z'urubura rwera rwagaragaye mu 1985, hasigaye ibirometero kare 4 gusa muri 2017. Kuri Noatak, igihe amabuye yagwaga n'umucanga ugasukwa mu ruzi, byabaye ngombwa ko tuzenguruka ibiti byacu hafi ya banki yashonze. Akayunguruzo k’amazi yo kunywa ni inshuro nyinshi gifunze imyanda yamenetse. Ubushakashatsi buherutse gukorwa ku nzuzi n’inzuzi ntoya muri ako gace bwerekanye ko gushonga permafrost bikonjesha amazi, abahanga mu binyabuzima bavuga ko bishobora kwangiza imyororokere ya salmon.Ibyo byateje impungenge ndende ku baturage ba kure bamanuka bishingikiriza kuri salmon kugirango babeho. Mugihe twagurukaga, twabonye kandi icyuzi cyitwa thermokarst cyihuta muri tundra verdant.Biterwa no gushonga kwurubura rwo hejuru hejuru ya permafrost ishonga. Ibiyaga nabyo byuzura mubibaya, kuko inkuta za tundra zikikije zashonga nkamavuta. Igihe ikirere cyarushagaho kuba cyiza kuri bo, ibihuru by'ibiti nabyo byerekeje mu majyaruguru muri tundra no mu byatsi byo hasi.Ibihuru na byo byimura ubushyuhe bwinshi bw'izuba binyuze mu rubura n'ubutaka kuri permafrost.Mu 1982, nasanze icyari gituwe n'umuryango w'impyisi. ku nkombe ndende ya Noatak, izengurutswe n'ibiti byitwa dwarf birebire byivi n'ibyatsi.Uyu munsi, inkombe nyinshi z'umugezi zuzuyemo ibiti by'imisozi miremire. Kuberako ibimera bitanga ingufu nyinshi hamwe n’aho gutura ku nyamaswa zo mu gasozi, iyi "Icyatsi kibisi" ihindura urusobe rw’ibinyabuzima byose.Bikururwa n’ibi biti by’ibiti, impongo, inzuki hamwe n’urubura rwa snowshoe ubu bigenda byerekeza mu majyaruguru kandi bigatera izindi mpinduka.Ibishishwa na byo bigabanya ibinyomoro. igifuniko, kikaba ari ibiryo byingenzi byimpongo zirenga 250.000 zinyura muri ako gace, zimwe murizo zikaba zikora ibirometero 2.700 kugera no kubyara. Nubwo twabonye impinduka zose, turacyasinze mubutayu bwa kure kandi butavumbuwe kuburyo mugihe cyibirometero 90, urugendo rwiminsi itandatu kuva mukiyaga cya Pingo kugera mukiyaga cya Kavaculak, twabonye undi muntu gusa. Twafashe umutego muruzi, kandi hanyuma tunywa ngo dusangire mugihe twirinze izuba ryaka munsi yurutoki rushyigikiwe.Twakubise hejuru yubururu bwo mwishyamba.Nyuma yo kumara isaha imwe mumuyaga utwara inyo kumusozi, twarebye idubu yijimye hamwe nibyana byayo, tutazi kubaho kwacu, gukonja muri tundra. Ibi byose ni ukubera ko impongo ziragira ibyana byazo kuva mu gikari cy’inyana zo mu cyi nkuko zimaze imyaka ibihumbi. Ntabwo twabonye abantu benshi, ariko twari tuzi ko bahari, ahantu, biruka mu matsinda, santimetero nke zitandukanye, ariko ntuzigere usunikana, hamstrings zabo nukuri castanets kanda Ijwi, ibinono byabo bikanda kumabuye.Ibiremwa bya tawny byanyuze munzira zabo za kera, nkumwotsi, unyura murimwe mubutayu bwacu bwa nyuma. Iyi parike ni ubutunzi bukomeye bwa demokarasi yacu kandi ifatwa nkurwibutso rwibisekuruza bizaza na Kongere ndetse na ba perezida bahozeho.Ubu barerekana ejo hazaza h’imihindagurikire y’ikirere, yibasiye Arctique mu buryo butigeze buboneka mbere ku isi ituje. Ijoro rimwe, sinshobora gusinzira, nanyuze kure y'umuhungu wanjye wari uri gusinzira, maze mva mu ihema ryacu, njya mu mucyo woroshye utangaje w'izuba rirenze, umukororombya wagoramye nk'ikiraro cyatanzwe n'Imana hejuru y'uruzi.Mu bihe nk'ibi. , Ndashobora gutekereza gusa abahungu banjye bombi, nuburyo bo hamwe nabadukomokaho bose bazahura nubudashidikanywaho bwubushyuhe bwisi. Jon Waterman yahoze arinda parike yigihugu akaba n'umwanditsi wa parike yigihugu ya Atlas ya National Geographic. Ibihe byiyemeje gutangaza amabaruwa atandukanye kubanditsi.Turashaka kumva ibitekerezo byawe kuriyi cyangwa ingingo zacu zose. Hano hari inama. Iyi ni imeri yacu: inyuguti@nytimes.com.
