Txawv txawv raws li nws yuav suab, tab sis cov teeb meem cuam tshuam nrog lub ntiaj teb ua kom sov, ntawm ib sab, ua rau muaj kev cuam tshuam tsis tau pom dua hauv cov neeg niaj hnub no, thiab ntawm qhov tod tes, tsawg tus neeg nkag siab txog qhov tshwm sim. Txhawm rau kom pom tseeb tias cov no tsis yog lwm "cov dab neeg txaus ntshai" ntawm ecologists, peb txiav txim siab los sau cov duab ntawm alpine glaciers ua los ntawm kev saib xyuas cov kws tshawb fawb hauv thaj tsam ntawm 100 xyoo. Qhov kev sib piv tau zoo heev.

Lub melting ntawm glaciers tau dhau los ua qhov pom kev zoo tshaj plaws uas qhov cuam tshuam ntawm kev hloov pauv huab cua tuaj yeem ntsuas tau. Cov kws tshawb fawb thiab cov kws tshawb fawb ecologists tau suab lub tswb, vim tias cov txheej txheem no yog cov pov thawj pom tseeb ntawm kev ua kom sov tsis tu ncua, uas yog qhov cuam tshuam rau tag nrho cov txheej txheem dej ntawm lub ntiaj teb.

Txhawm rau kom nkag siab qhov loj ntawm qhov teeb meem, qee lub sijhawm, cov kws tshawb fawb tau mus rau qhov chaw uas cuam tshuam los ntawm kev hloov pauv huab cua. Piv txwv li, kev sib piv ntawm cov duab thaij nyob rau hauv Alps ntawm lub sijhawm sib txawv qhia meej tias lawv lub zog tsis muaj zog yog qhov kev puas tsuaj loj zuj zus tuaj, thiab cov kev kwv yees ntxiv kuj poob siab.

Xyoo 1850, lawv cheeb tsam yog 1,735 km², thiab los ntawm 2020, tsuas yog 890 square km ntawm lawv. Nws yog kev nyuaj siab kiag li tias tus nqi ntawm melting nce txhua xyoo. Yog hais tias nyob rau hauv thawj 120 xyoo cov dej khov nyob rau hauv lub alpine highlands tau txo los ntawm 400 square meters, ces nyob rau hauv lub xeem 50 - lub glaciers tau txo los ntawm 445 square meters.

Nrog rau qhov tshwm sim ntawm aviation, cov kws tshawb fawb thiab cov kws tshawb fawb muaj lub sijhawm tshwj xeeb los soj ntsuam cov txheej txheem poob siab saum ntuj. Tsis ntev los no, lub ntiaj teb xav tsis thoob los ntawm cov duab tshiab ntawm Scottish University of Dundee, uas tau txiav txim siab los ua qhov kev ntsuam xyuas saum toj kawg nkaus ntawm thaj chaw uas tau yees duab los ntawm Walter Mittelholzer 100 xyoo dhau los.

Curriculum Vitae: St. Gallen Walter Mittelholzer (1894-1937) ua ke aviation thiab yees duab ua lag luam muaj txiaj ntsig. Nws yog tus tsav, tus sau phau ntawv, ua lag luam, xov xwm hnub qub, Swissair co-founder thiab kws yees duab. Thaum nws lub neej luv luv, nws tau ua yeeb yaj kiab, ua cov duab thiab yeeb yaj kiab, sau phau ntawv thiab sau cov duab loj loj, suav nrog ntau dua 18 txhiab daim duab, uas nws coj thaum mus ncig thoob ntiaj teb. Txawm tias muaj tseeb hais tias Mittelholzer yog ib tug neeg tsav dav hlau, nws tuag los ntawm lub cev qhuav dej nyob rau hauv ib tug mine thaum filming nws tom ntej masterpiece.

Raws li cov kws kho ntawm Novate. Ru, Kieran Baxter thiab Alice Watterston tau ya hla Mont Blanc Bossons, Mer de Glacy thiab Argentier, noj cov duab ntawm roob toj roob hauv pes, uas tau tua thaum Lub Yim Hli 1919 los ntawm Walter Mittelholzer. Roob peaks thiab peaks, pom nyob rau hauv daim duab ntawm lawv predecessor, tau los ua cov ntsiab lus rau geolocation.

Ib tug ntawm cov tswv cuab ntawm kev tshawb fawb tshawb fawb tau tawm tswv yim txog qhov nws pom: "Qhov loj ntawm cov dej khov poob tau tshwm sim sai li sai tau thaum peb nce mus rau saum ntuj, tab sis tsuas yog los ntawm kev sib piv cov duab coj los ntawm ib qho, peb puas tuaj yeem pom cov kev hloov pauv yav dhau los. 100 xyoo. Nws yog qhov pom kev zoo siab thiab mob siab rau, tshwj xeeb tshaj yog paub tias kev sib tsoo tau nrawm heev nyob rau ob peb xyoos dhau los."

Hauv Switzerland, lub chaw tshawb fawb rau kev kawm txog cov dej khov "Glamos" ("Das Schweizerische Gletschermessnetz") tab tom kawm txog qhov teeb meem no. Nws cov kws tshawb fawb tau suav ntev ntev tias los ntawm qhov kawg ntawm lub xyoo pua xyoo no cov dej khov hauv Switzerland yuav txo qis los ntawm 80-90%, thiab nws yuav tsis muaj peev xwm zam kev puas tsuaj, txawm tias cov txheej txheem ua kom sov.

Kev poob ntawm cov dej khov tuaj yeem ua rau muaj teeb meem loj ntsig txog kev siv dej. Tsis tsuas yog ob peb lub tebchaws yuav raug tshem tawm ntawm qhov chaw ntawm cov dej haus huv ib zaug, yog li teeb meem ntawm kev tsim hluav taws xob yuav pib, vim tias cov dej yaj tau koom nrog cov txheej txheem tsim khoom.

Tab sis tsis yog txhua yam, qhov chaw zoo nkauj ntawm Alps thiab thaj chaw dej khov muaj zog nyiam cov neeg tuaj ncig xyuas zoo li cov hlau nplaum, thiab qhov no yog cov nyiaj tau los ntau rau cov nyiaj txiag ntawm lub tebchaws. Tsis tas li ntawd, qhov melting ntawm glaciers yuav ua rau muaj kev nce qib ntawm avalanche txaus ntshai nyob rau hauv cov roob siab.

Lub qhovntsej thiaj tsis mob avalanches nyob rau ntau pua xyoo keeb kwm tau ua ntau yam teeb meem, uas tau hais tias yuav luag txhua hnub pom nyob rau hauv qhov chaw ntawm cov dej khov yaj. Retreating glaciers qhia tragic secrets. Tsis ntev los no, nyob rau ntawm qhov chaw siab tshaj, muaj ntau cov khoom seem ntawm cov khaub ncaws, qhov chaw ntawm cov khoom siv thiab cov khoom tawg ntawm lub cev ntawm cov neeg tuag tau pom nyob rau ntawm qhov chaw siab tshaj, uas tau nyob hauv qab npog dej khov rau ntau xyoo lawm.

Hmoov tsis zoo, tsis tsuas yog cov dej khov uas ploj lawm hauv peb thaj av. Cov kws tshawb fawb kwv yees tias tsis ntev ntawm lub ntiaj teb peb yuav tsis pom ntau qhov chaw nthuav dav uas xwm thiab tib neeg tau tsim.
