Iglacier yeGrey iphulukana nenye ibhloko yomkhenkce

ukunyibilika kweGrey glacier

Ukunyuka kwamaqondo obushushu aphakathi kwehlabathi kubangela ukunyibilika okungalawulekiyo komkhenkce ojikeleze umhlaba. Kutshanje kuye kwafundwa ukuba ibhloko enkulu yomkhenkce iqhekeza iGrey Glacier, eTorres del Paine. Ibhloko lomkhenkce elingafaniyo linobukhulu obuyi-350 × 380 yeemitha.

Injani iGrey glacier ebusweni bokunyuka kweqondo lobushushu?

Indawo yebhloko

Ukuqhekeka komkhenkce ngwevu

Ibhloko ehlukaniswe neGrey Glacier yongeza kwinani lomkhenkce elahlekileyo kule minyaka ilishumi elinambini idlulileyo. Umkhenkce uphulukane nomyinge wama-900 eemitha zomkhenkce kangangeminyaka elishumi elinambini kuphela.

Ugqirha Raúl Cordero ngumphandi oyingcali kutshintsho lwemozulu nakwizifundo kwiDyunivesithi yaseSantiago kwaye uqinisekisa ukuba ukufunyanwa kwesi siqwengana somkhenkce kuya kubangela ubunzima bokwenyani. Ukongeza, iqinisekisa ukuba iGlacier yeGrey ayikho enkulu kunezo zilahlekileyo ePatagonia.

Ukuphulukana okuqhubekayo komkhenkce kuye kwaba yinto engenakuguqulwa ebangelwe kukufudumala komhlaba. Njengoko amaqondo obushushu aphakathi enyuka, isixa somkhenkce esinyibilikayo sikhulu, njengoko amaxesha ashushu ahlala ixesha elide.

"Ingozi kwixesha eliphakathi nelide kumanxweme afana neChile kukuba ilahleko yomkhenkce iyaqhubeka," yintoni eyenza ukuba ulwandle lukhuphuke. Ekupheleni kwenkulungwane, ukwanda okulindelweyo, kwimeko ezintle, kungayimitha enye ngaphezu komphakamo wolwandle kwaye lonto ininzi ”utshilo umphandi.

Kufuneka kuthathelwe ingqalelo ukuba iindawo ezichaphazeleka kakhulu ziziphumo zokunyibilika komkhenkce ngokuqhubekayo zizixeko eziselunxwemeni. Isixa samanzi esigciniweyo kumkhenkce omkhulu kakhulu kwaye xa siqala ukunyibilika ngokukhawuleza njengoko sisenza namhlanje, sikhokelela kwizikhukula ezoyikekayo.

Njengomkhenkce onyibilikayo, ayizukuchaphazeleka kuphela izixeko eziselunxwemeni zizikhukula, kodwa ziya kuchaphazeleka kukunyuka kwamazinga olwandle. Olu konyuka aluyongozi kuphela kuba maninzi amanzi, kodwa ubukhulu becala, lunokuchaphazela amanxweme ngokuqatha xa kukho isaqhwithi kunye nomoya ngenxa yesixa esikhulu samanzi kwiilwandle nakwiilwandlekazi.

“Ingxaki kwihlabathi liphela kukuba umkhenkce omkhenkce uphelelwe lixabiso. Koko kukuthi, imali eseleyo: balahlekelwa ngumkhenkce ongakumbi ngokunyibilika okanye ngohlobo lomkhenkce kunokuba befumana ikhephu, ”ucacisa watsho uCordero.

Kuyingozi ngenene ukuba umkhenkce omkhenkce uyanyibilika, kuba, ngaphaya kokunyuka komphakamo wolwandle kunye nezikhukula, amaqhekeza womkhenkce yeyona nto iphambili ekusebenzeni kwendalo ehambelana nayo.

Ubushushu bukazwe lonke

Umkhenkce ongwevu

Njengokuba ubushushu behlabathi buqhubela phambili, isidingo sivela ngakumbi ukunciphisa iziphumo kunokuba sizame ukukuyekisa. Iziphumo ezibangela utshintsho lwemozulu yehlabathi sele zikufuphi kwaye akunakwenzeka ukuba zinqandwe. Into ekufuneka yenziwe ukunciphisa imeko yokutshintsha kwemozulu ngokunciphisa ukukhutshwa kwegesi yendalo ngokutshintsha kwamandla ngokusekwe kumandla ahlaziyekayo.

IGrey glacier yenye yezona zikhulu ePatagonia, kodwa ayisiyiyo eyona ilahlekileyo. Kule ndawo kukho ukuncipha ukuya kuthi ga kwi-13 yeekhilomitha kumashumi amathathu nje eminyaka.

"Akukho sikhombisi sokutshintsha kwemozulu esingakhawulezi kakubi. Amanqanaba olwandle anyuka ngokukhawuleza kwaye ngokukhawuleza; Umkhenkce uyanyibilika ngokukhawuleza nangokukhawuleza; IGreenland neAntarctica balahlekelwa ngumkhenkce ongakumbi; sineenguqu ezibonakalayo kulandelelwano lweziganeko ezigabadeleyo ezinje ngezaqhwithi ezigqithisileyo, iinkanyamba ezinkulu, imbalela enkulu, amaza obushushu; Kwaye konke oku, ngokwendalo, kukubonakalisa ukukhawulezisa utshintsho lwemozulu ”, uqukumbela watsho uCordero.

Ukunyibilika komkhenkce kukhawulezisa ukutshintsha kwemozulu, kuba njengoko ikhephu lincinci, isixa esincinci semitha yelanga siyabonakala kwaye, ke ngoko, ubushushu obuninzi buyabanjwa obonyusa amaqondo obushushu ngakumbi.
