Zininzi izinto ezahlukeneyo ezichaphazela ukufudumala kwehlabathi kunye notshintsho lwemozulu. Ngamanye amaxesha kukho izinto ezenza igalelo ekunyukeni kweziphumo ezibi, kodwa ngamanye amaxesha, iziganeko zenzeka ezinegalelo kuphuculo lwazo.
Nangona amaqondo obushushu anyukayo abangelwa kukufudumala kwehlabathi kubangela ukunyibilika kwekhephu lonyaka ngaphambi kwentwasahlobo, oku kuyakuvumela amahlathi ashinyeneyo anokufunxa ikharbon diokside engakumbi yeatmosfera. Kwenzeka njani oku?
Ikhephu liyanyibilika
Ubushushu behlabathi ikakhulu bubangelwa kukufunxwa kobushushu yi-carbon dioxide ekhutshwa zizenzo zabantu. Ioli evuthayo, amalahle kunye negesi yendalo zivelisa ukukhutshwa kwegesi ekhulisa ubushushu obandisa ubushushu beplanethi, kwaye oku kubangela ukuba ikhephu linyibilike ngaphambi kwexesha lalo. Njengotshintsho lwemozulu yehlabathi, kukho ukukhawulezisa kwezinye iinkqubo ezinjengokunyibilika komkhenkce osemkhenkceni, ukunyuka kwamanqanaba olwandle kunye nokwanda kwezihlandlo zemozulu ezibi kakhulu.
Ukwazi ngqo ikhabhon dayoksayidi esemoyeni, kufuneka kulungelelaniswe phakathi kwezinto ezikhutshiweyo kwaye zifunxwe zizityalo kwinkqubo yefotosinthesisi nakwezinye iisinki ze-CO2 elwandle.
LAmahlathi emithi eyaziwa njengeendawo zokuntywila ezibalulekileyo ze-CO2, kodwa baxhomekeke ngokupheleleyo kwinani lekhephu abanalo, kuba yinto egqibayo yokufunxa i-CO2. Okukhona benekhephu, kokukhona baya kuncipha i-CO2, nangona bekwabonisa ubushushu obungaphezulu.
Izifundo zokufakwa kwi-CO2
Ukunceda ukuguqula utshintsho ekuthathweni kwekhabhoni, Iprojekthi ye-ESA yeGlobSnow isebenzisa idatha yesathelayithi ukuvelisa iimephu zekhephu zemihla ngemihla kuyo yonke iNyakatho yeHlabathi phakathi kuka-1979 no-2015.
Ukuqala kokukhula kwezityalo kumahlathi atyibilikayo kuyaqhubela phambili ukusuka malunga neentsuku ezisibhozo kule minyaka ingama-36 idlulileyo. Oku kukhokelela ekubeni utyani lukwazi ukugcina ngakumbi i-CO2 lakuba nje ikhephu linyibilika. Oku kuye kwafunyanwa liqela lezenzululwazi elijolise kwimozulu nakwimitha ekude, ekhokelwa liZiko leMozulu laseFinland.
Xa befumana olu lwazi, bayayidibanisa notshintshiselwano ngecarbon dioxide phakathi kwendalo kunye nomoya ojikeleze amahlathi aseFinland, eSweden, eRashiya naseKhanada. Nje ukuba benze oku, iqela likwazile ukufumanisa ukuba ukuvela kwangaphambili kwentwasahlobo kubangele ukugcinwa 3,7% ngaphezulu kwe-CO2 kunangaphambili. Oku kunegalelo ekunciphiseni ukukhutshwa kwe-CO2 kumoya obangelwa ngabantu.
Ukongeza, okunye okufunyaniswe leli qela kukuba umahluko ekukhawuleziseni kwentwasahlobo kwenzeka ngendlela ebonakala ngakumbi kumahlathi ase-Eurasia, ukuze ukufunxeka kwe-CO2 kule mimandla kuphindwe ngokubhekisele kumahlathi AmaMelika.
“Idatha yesethelayithi idlale indima ebalulekileyo ekunikezeleni ulwazi malunga nokwahluka komjikelo wekhabhoni. Ngokudibanisa ulwazi lwesathelayithi kunye nolwandle, sikwazile ukuguqula ukujongwa kwekhephu linyibilike libe lulwazi oluphezulu malunga nokusebenza kwentwasahlobo kunye nokufunxwa kwekhabhoni, utshilo uNjingalwazi uJouni Pulliainen, owayekhokele iqela labaphandi kwiZiko leMeteorological. Finnish.
Iziphumo ezifunyenwe kolu phando ziya kusetyenziselwa ukuphucula iimodeli zemozulu kunye nokuqikelela malunga nokufudumala komhlaba. Njengolwazi oluthe kratya kwezenzululwazi malunga nokusebenza kwendalo kunye notshintshiselwano lwazo kunye namandla kumoya ojikeleze umhlaba, ngcono iimodeli zokubikezela ukuba bazokulungiselela iimeko ezintsha zemozulu ezisilindeleyo.
Kubalulekile ukufaka ulwazi ukuze wenze imigaqo-nkqubo esinceda ukunciphisa utshintsho lwemozulu okanye ukuziqhelanisa neziphumo zalo ezibi eluntwini. Olu phando lumele impumelelo kwinkalo yokufakwa kwe-CO2.
