La Ukuqhuma kwentaba-mlilo iMauna Loa Esiqhingini saseHawaii ngeSonto eledlule, ngo-November 27, akekho owamangala, njengoba iyintaba-mlilo enkulu kunazo zonke emhlabeni futhi bayiziqhingi ezingajwayele ngisho nokuhlala nodaka. Nokho, esiqongweni sentaba-mlilo, endaweni ephakeme ngamamitha angu-3.400 XNUMX, izinto ziyashintsha. Ukuzwa kwe-alamu kubonakala kakhulu njengoba indawo yokubuka intaba-mlilo ikhona. Le ndawo yokuhlola inkomba yomhlaba wonke yokulinganisa ukugcwala komkhathi we-carbon dioxide, okuyigesi ebamba ukushisa eyinhloko ebangela ukushintsha kwesimo sezulu. Umbuzo uwukuthi ingabe ukuqhuma kwale ntaba-mlilo kungase kubangele izinguquko kudatha eqoqwe i-observatory.
Ngakho-ke, kulesi sihloko sizokutshela mayelana nedatha erekhodiwe nokuthi ukuqhuma kuthinta kanjani ukuguquka kwesimo sezulu.
uthando lwe-lava
Ukuphuma kwabantu nokunqamuka kukagesi eMauna Loa Observatory kulandela ukuqhuma kumise umsebenzi walesi sikhungo. Ayikho idatha erekhodiwe kusukela ntambama ngoMsombuluko womhla zingama-28. “Amasistimu ethu okuhlaziya kanye nemishini yokuqapha igesi ehlobene nokutholwa kwedatha kudinga amandla ukuze asebenze, ngakho ahlala engenzi lutho. Noma ngamandla, kodwa akukho ukufinyelela komgwaqo, ezinye izinsimbi ziyabhajwa futhi zimekubika i-Mauna Loa Observatory.
Njengamanje, ukugeleza kwe-lava akubeki amathuluzi noma izindawo zokubuka engcupheni. Futhi azibeki usongo kubantu bendawo, njengoba zihlala kude nezikhungo zabantu. Ngaphandle kwalokhu, i-United States Geographic Survey igcina izinga elibomvu lesexwayiso kuso sonke isiqhingi. Futhi, Uxwayise ngokuthi iziqhumane kulesi sifunda zivame ukuqhuma kakhulu futhi ukugeleza kwe-lava kungashintsha indlela ngokushesha.
Izazi zesayensi yokwakheka komhlaba zithi lesi simo siyakhathaza kakhulu ngoba ukuqhuma kusendaweni embi futhi kukhulu. Kucatshangwa ukuthi ngeke ibuyele kwesijwayelekile izinyanga ezimbalwa. Njengoba udaka luqhubeka endleleni yalo yemvelo, elimazayo, ithimba labacwaningi laphithizela ukuze lithole indawo ephephile eduze ukuze likwazi ukuqala izilinganiso zedatha okwesikhashana. Kuyabonakala ukuthi udaka luwele umgwaqo obheke eMauna Loa Observatory.
Izilinganiso zomhlaba wonke ze-CO2
Omunye umbuzo omkhulu ophakamayo ngemuva kokuqhuma wukuthi kwenzekani ezingodweni uma imishini isilungisiwe. I-Carbon dioxide ingelinye lamagesi amaningi akhishwa izintaba-mlilo., ngakho-ke kunengqondo ukuthi ukube ukuqhuma kwenzeke eduze kakhulu nosuku, amathuluzi okubuka izinto abeyobona ukwanda okusheshayo kwe-carbon dioxide, ahlole ngokungalungile igesi ebamba ukushisa emkhathini. “Uma uhlelo lokuhlaziya lusebenza kahle, luzobhalisa ukwanda kwe-carbon dioxide uma umoya uvunguza usuka lapho kuqhume khona. Kodwa-ke, lapho umoya uvunguza kwezinye izindawo, izilinganiso ngeke zithinteke, ”kusho izazi ze-geoscientists.
Ngaphezu kwalokho, uma kwenzeka, lezi ziphazamiso zizoba ezesikhashana futhi ngeke zibe nomthelela ekulinganisweni okuphelele kwe-Mauna Loa Observatory, engalinganisi ukugxiliswa kwe-CO2 yendawo kodwa lokho okubizwa ngokuthi ukugxila kwe-CO2 yangemuva. Indawo yayo phezu kwale ntaba-mlilo maphakathi nolwandle iwukugwema iziphazamiso eziningi kanye nemithombo yendawo yokungcola. Ngaphezu kwalokho, kusukela ekuqaleni yayilungiselelwe ukubona izinguquko ezikhiqizweni zasendaweni, njengokuqhuma kwentaba-mlilo, nokwenza izilungiso kumarekhodi ayo.
Ososayensi bemvelo banentshisekelo enkulu yokulinganisa ukugxila kwe-CO2 engemuva ku-Mauna Loa, lapho bengabona khona imiphumela yokukhishwa kwesisi esibamba ukushisa izinkulungwane zamakhilomitha ukusuka endaweni yokuhlola. Endabeni yemithombo yendawo yokukhipha umoya, njengokuqhuma kwentaba-mlilo, kulula ukubona ukuchezuka esilinganisweni esisekelwe ekuqondeni komoya. Eqinisweni, yilokho abakwenza phakathi nokuqhuma komlilo ngo-1984.
Futhi, ngale kwezilinganiso ze-observatory, mangakanani amandla alokhu kuqhuma ukwandisa ukugcwala komhlaba wonke kwe-CO2 emkhathini? Ngemva kwakho konke, Iplanethi ifudumale cishe ngo-1,3ºC kusukela ezikhathini zangaphambi kwezimboni, lapho u-0,75ºC ungenxa ye-carbon dioxide. Izazi ze-Geoscientists zithi Ngeke kuthinte cishe noma yini.
Ngokufanayo, umcwaningi wesundu u-Omaira García Rodríguez wachaza ukuthi "ngesikali sendawo noma sesifunda, futhi ngezikhathi ezifushane kakhulu, ukugxila kwe-CO2 okuphawuliwe kungahluka kakhulu ngenxa yomthelela wokukhishwa kwentaba-mlilo", nokho, "ukukhishwa kwe-CO2 kanye njengazo zonke izinqubo zokuqhuma ngokuvamile, lolu hlobo lwentaba-mlilo alubalulekile ekulinganisweni komhlaba wonke”.
Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nokuqhuma kwe-Mauna Loa kanye nokukhishwa kwayo kwe-carbon dioxide.
