La Ugqabhuko-dubulo lwentaba-mlilo yaseMauna Loa Kwisiqithi saseHawaii ngeCawa edluleyo, ngoNovemba 27, akukho mntu wamangaliswayo, ekubeni iyeyona ntaba-mlilo inkulu emhlabeni yaye ziziqithi ezingaqhelanga nokuhlala nodaka. Noko ke, encotsheni yentaba-mlilo, kumphakamo oziimitha ezingama-3.400 XNUMX, izinto ziyatshintsha. Uvakalelo lwe-alam lubonakala ngakumbi njengoko indawo yokujonga intaba-mlilo ikhoyo. Esi sixhobo sokuhlola sisalathiso sehlabathi sokulinganisa i-atmospheric concentration ye-carbon dioxide, eyigesi enkulu ye-greenhouse ebangela ukutshintsha kwemozulu. Umbuzo ngowokuba ingaba ugqabhuko-dubulo lwale ntaba-mlilo lunokubangela utshintsho kwidatha eqokelelwe yi-observatory.
Ngoko ke, kweli nqaku siza kukuxelela malunga nedatha erekhodiweyo kunye nendlela ukuqhuma okuchaphazela ngayo utshintsho lwemozulu.
uthando lwelava
Ukufuduka kwabantu kunye nokucima kombane kwiMauna Loa Observatory emva kogqabhuko-dubulo kuye kwamisa imisebenzi yeli ziko. Akukho datha irekhodiweyo ukususela emva kwemini ngoMvulo we-28. "Iinkqubo zethu zokuhlalutya kunye nokubeka iliso kwegesi ehambelanayo kunye nezixhobo zokufumana idatha zifuna amandla okusebenza, ngoko zihlala zingasebenzi. Nangona ngamandla, kodwa akukho ndlela yokungena, ezinye izixhobo ziyaxinga zize zimeinika ingxelo iMauna Loa Observatory.
Okwangoku, ukuhamba kwe-lava akubeki izixhobo okanye izixhobo zokujonga emngciphekweni. Kananjalo azibeki soyikiso kubemi bendawo, njengoko behlala bekude kumaziko oluntu. Ngaphandle koku, i-United States Geographic Survey igcina inqanaba elibomvu lesilumkiso kwisiqithi sonke. Kwakhona, Ulumkise ngelithi ugqabhuko-dubulo kulo mmandla luhlala lusebenza kakhulu kwaye ukuqukuqela kwe-lava kunokutshintsha indlela ngokukhawuleza.
Izazinzulu ngokuma komhlaba zithi le meko ixhalabisa kakhulu kuba olu gqabhuko-dubulo lukwindawo embi kwaye lukhulu. Kucingelwa ukuba ayisayi kubuyela kwimeko yesiqhelo kwiinyanga ezimbalwa. Njengoko i-lava yayiqhubeka kwindlela yayo yendalo, eyonakalisayo, iqela labaphandi liye lazama ukufumana indawo ekhuselekileyo ekufutshane ukuze baqalise okwethutyana imilinganiselo yedatha. Kuyabonakala ukuba udaka lunqumla indlela eya kwiMauna Loa Observatory.
Imilinganiselo ye-CO2 yehlabathi
Omnye umbuzo omkhulu ovela emva kogqabhuko-dubulo kukuba kwenzekani kwizigodo emva kokuba isixhobo sibuyiselwe. Ikharbon diokside yenye yeegesi ezininzi ezikhutshwa ziintaba-mlilo., ngoko ke kusengqiqweni ukuba ukuba ugqabhuko-dubulo lwenzeke kufutshane nomhla, izixhobo ze-observatory beziya kubona ukwanda ngokukhawuleza kwekharbon diokside, zifumanisa kakubi igesi ye-greenhouse emoyeni. “Ukuba inkqubo yohlalutyo isebenza ngokuchanekileyo, iya kubhalisa ukunyuka kwekharbon diokside xa umoya uvuthuza usuka kwindawo yogqabhuko-dubulo. Nangona kunjalo, xa umoya uvuthuza kwelinye icala, imilinganiselo ayizukuchaphazeleka, ”zitshilo izazinzulu.
Ukongeza, ukuba zithe zenzeka, ezi ziphazamiso ziya kuba zezokwexeshana kwaye aziyi kuba nampembelelo kuyo yonke imilinganiselo ye-Mauna Loa Observatory, engalinganisi ugxininiso lweCO2 lwendawo kodwa into ebizwa ngokuba yimvelaphi yeCO2. Indawo yayo phezu kwale ntaba-mlilo embindini wolwandle ngokuchanekileyo ukuphepha uninzi lokuphazamiseka kunye nemithombo yendawo yongcoliseko. Ukongezelela, kwasekuqaleni yayilungiselelwe ukubona utshintsho kwizinto ezikhutshwa ekuhlaleni, ezinjengogqabhuko-dubulo lwentaba-mlilo, ize lenze izilungiso kwiirekhodi zayo.
Iingcali ze-Geoscients zinomdla ngakumbi ekulinganiseni imvelaphi ye-CO2 yokugxila kwi-Mauna Loa, apho banokubona iziphumo zokukhutshwa kwegesi yegreenhouse amawaka eekhilomitha ukusuka kwindawo yokuqwalasela. Kwimeko yemithombo yendawo ekhutshwayo, efana nogqabhuko-dubulo lwentaba-mlilo, kulula ukubona iitenxa kwimilinganiselo esekelwe kwicala lomoya. Enyanisweni, yiloo nto kanye abayenzayo ebudeni bogqabhuko-dubulo ngowe-1984.
Kwaye, ngaphaya kwemilinganiselo ye-observatory, yintoni enokubakho yolu gqabhuko-dubulo lokunyusa izinga le-CO2 kwi-atmosfera? Emveni kwakho konke, Iplanethi ifudunyezwe malunga ne-1,3ºC ukususela kumaxesha angaphambi kwamashishini, apho i-0,75ºC ibangelwa yi-carbon dioxide. Iingcali ze-Geoscientists zithi Ayizi kuchaphazela phantse nantoni na.
Ngokufanayo, umphandi wesundu u-Omaira García Rodríguez wachaza ukuba "kwinqanaba lendawo okanye lengingqi, kwaye ngexesha elifutshane kakhulu, ukugxininiswa kweCO2 kunokwahluka kakhulu ngenxa yempembelelo yokukhutshwa kwentaba-mlilo", nangona kunjalo, "ukukhutshwa kweCO2 kunye njengazo zonke iinkqubo zogqabhuko-dubulo ngokubanzi, olu hlobo lwentaba-mlilo alubalulekanga kwibhalansi yehlabathi”.
Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi ngogqabhuko-dubulo lwaseMauna Loa kunye nokukhutshwa kwekharbon diokside.
