Njengokuba inani labantu lisanda, sinyuka nesidingo: izindlu ezingaphezulu, ifanitshala engaphezulu, iphepha elininzi, amanzi amaninzi, ukutya okungakumbi, phakathi kwezinye izinto ezininzi ziyafuneka. Ukuyanelisa, bekukhethwe iminyaka emininzi ukuya amahlathi anamahlathi, yenye yemiphunga yoMhlaba kuba ifunxa ikharbhon diokside kwaye ikhuphe ioksijini emoyeni, nanjengoko sisazi ukuba yirhasi esiyidingayo ukuze siphefumle kwaye, ukuze siphile.
Ukutshatyalaliswa kwamahlathi kunegalelo ekwenzeni ubushushu behlabathi bube mandundu. Kodwa, Njani?
Izifundo ezibini ezipapashwe kwijenali yenzululwazi zityhila oko ukugawula imithi kwandisa iqondo lobushushu ngaphezu kokukholelwa ngaphambili. Eyokuqala, evela kwiZiko lokusiNgqongileyo kunye noZinzo lweZiko eliHlanganisiweyo loPhando lweKhomishini yaseYurophu (i-JRC), ichaza indlela ukugawulwa kwamahlathi kuchaphazela ngayo ukuhamba kwamandla kunye namanzi phakathi komhlaba nomoya ojikeleze umhlaba, njengoko sele kusenzeka kwimimandla. yetropiki.
Kwimeko yesibini, ezilungiselelwe ngumphandi uKim Naudts ovela kwiLebhu yezeNzululwazi ngezeMozulu kunye nezeNzululwazi ngezeNdalo ePierre Simon Laplace Institute (eFrance) kunye neqela lakhe, kuyaboniswa ukuba nangona ukhuseleko lomthi eYurophu lusanda, iindidi »kubangela isiphumo esichasayo sokuzala». Ukusukela ngo-2010, ama-85% amahlathi ase-Europe alawulwa ngabantu, kodwa abanye abantu banolwazelelelo kwabo banexabiso elikhulu kwezorhwebo, njenge-beech pines. Amahlathi aluhlaza ancitshisiwe ngama-436.000km2 ukusukela ngo-1850.
Utshintsho kubushushu ngenxa yolawulo lomthi olubi.
Ukutshintshwa kwamahlathi achumileyo kunye namahlathi e-coniferous kubangele utshintsho kwi-evapotranspiration kunye ne-albedo, oko kukuthi, isixa samandla elanga abonakaliswe abuyele emajukujukwini. Olunye utshintsho olwenza ubushushu behlabathi bube mandundu. Ngokwababhali, Izakhelo zemozulu kufuneka zithathele ingqalelo ulawulo lomhlaba kunye nokugubungela kwawo ukuze uqikelelo luchane ngakumbi.
Ngaphandle kwezityalo umntu akanalo ithuba, ke ngoko Kubalulekile ukuba kuthathwe amanyathelo ayimfuneko ukuze ungagqibi ukuhlala kwiplanethi ephantse ibe yintlango.
