Wakhe weva ukusuka kumphunga weplanethi, Ebhekisa kwiAmazon okanye ezinye iindawo eziluhlaza zeplanethi. Ezi ndawo zibizwa ngokuba yimiphunga, kubhekiswa kumandla okufunxa i-CO2 kwiplanethi kwaye ngenxa yoko inegalelo kwimeko ecocekileyo nenempilo kubo bonke abantu abaphilayo.
Omnye wemiphunga wale planethi ubekwe ummandla weAtlantic ojikeleze iTropic yomhlaza. Le miphunga yindawo yolwandle ekhulula iplanethi kwinxalenye enkulu ye-CO2 ekhutshwa ngabantu. Ngaba iyekile ukusebenza ngentwasahlobo ka-2010?
Umphunga weAtlantic
Iilwandlekazi zinokufikelela ukufunxa izixa ezikhulu CO2 ukuba sikhuphe kwimisebenzi yethu yezamashishini kwaye siyisuse kumjikelo, siyizinzise kunxano. Kukho ulungelelwaniso lwekhabhoni lwehlabathi apho, xa kukho ikhabhoni eninzi emoyeni, ithambekele ekunyibilikeni emanzini olwandle. Yintoni ingxaki ngale nto? Xa i-CO2 ininzi ibandakanyiwe elwandle, ziyachuma kwaye ngenxa yoko zinefuthe elibi kwizityalo nezilwanyana zaselwandle. Elona tyala laziwa kakhulu kukukhanya kwe-coral reef.
Ewe, uphononongo olwenziwe kukufunxwa kwe-CO2 ziilwandle ziqikelela ukuba ziyakwazi ukufunxa phakathi I-40 kunye ne-50% yayo yonke ikharbon dayokhsayidi ekhutshwe yimisebenzi yoluntu ukusukela kuguquko kwimizi mveliso. Le njini inceda ukususa iplanethi ye-CO2 engaka ikwanobungakanani obuthathaka obuxhomekeke, ubukhulu becala, kumaqondo obushushu ehlabathi.
Kukho izifundo ezilumkisa ukuba kangangesiqingatha senkulungwane ukuba le miphunga yaselwandle isikhululela kwezi gesi zegreenhouse kwaye inciphise iziphumo ezibi kunye neziphumo kwimozulu eziphelelwe ngamandla. Imagazini Iingxelo zeSayensi, yeQela leNdalo, elipapashwe ngoJanuwari 30, 2017, uphononongo olumkisa malunga nokunyuka kwamaqondo obushushu abangelwa zizinto zendalo kunye nomntu, kunokubangela ulwandle ukuba luye ekucoceni iatmosfera ukuyilayisha nangoku iigesi ezingaphaya kokushisa.
Kwenzeka ntoni entwasahlobo ka-2010?
Ngenxa yokwanda kokukhutshwa kwegesi eluhlaza kwindalo, amaqondo obushushu ehlabathi awayeki ukunyuka unyaka nonyaka. Lo mmandla weAtlantic owaziwa ngokuba yimiphunga yaselwandle udlala indima ebalulekileyo: i-ikhweyitha yangoku esemantla kunye nezo zidlulayo kwiiCanary Islands, ezimbini zezinto ze-oceanic gyre elawula imozulu kuloo ndawo.
Nangona kunjalo, ngentwasahlobo ka-2010 le miphunga yayeka ukusebenza ngenxa yokunyuka okukhulu kwamaqondo obushushu ngenxa yeziphumo ezishiyekileyo ngenxa yenyani El Niño Xa ibingasebenzi ngexesha lentwasahlobo yowama-2009, iyekile ukufunxa malunga nezigidi ezingama-2010 zeetoni ze-CO420, Oko kukuthi, Iipesenti ezingama-30 zizonke ezikhutshwayo.
Ngentwasahlobo ka-2010, iziphumo ze-El Niño kunye ne-Multi-Decade yeAtlantic Oscillation yabangela ubushushu bomhlaba wolwandle kuloo ndawo ukuze inyuka nge-3,4 degrees ngaphezulu kwesiqhelo kwaye isantya somoya sitshintshile, esiphazamise iindlela ezimbini ezilawula ukufunxwa kwe-CO2.
Ngenxa yale meko, indlela yemiphunga yolwandle yawa okwethutyana, isenza ukuba ingabinakho ukufunxa i-29 yezigidi zeetoni ze-CO2 phakathi kukaFebruwari noMeyi. Kufuneka kukhankanywe ukuba ngentwasahlobo ka-2010 Zizigidi eziyi-1,6 zeetoni zegesi eluhlaza ezikhutshelwe emoyeni.
Imimandla apho kukho utshintsho olukhulu
Olona tshintsho lubalulekileyo lujolise kumantla e-ikhweyitha yangoku. Kuloo ndawo ulwandle lwaphumela emoyeni ngezo nyanga malunga ne-1,2 yezigidi zeetoni ze-CO2, xa into eqhelekileyo kukuba ithatha i-22,4 yezigidi.
Umkhwa wokunyuka kwamaqondo obushushu behlabathi kufudumeza amanzi aphezu kweelwandle. Oku kubangela ukwanda kokuqina kunye nokuhamba rhoqo kweziganeko zemozulu ezibaxekileyo. Oku kungasongela amandla alo mphunga ukunciphisa iziphumo ze-CO2 kunye nokuzifunxa.
