Namhlanje amaqondo obushushu ehlabathi ukuvuka kunye nokwaphula iirekhodi phantse rhoqo ngenyanga. Le Agasti iphelileyo iyeyona ishushu kuba bekukho iirekhodi zobushushu behlabathi emva phaya ngo-1880.
Iiarhente ezininzi ezisemthethweni zibeke u-2014 njengowona nyaka ushushu kakhulu kunye namaqondo aphezulu obushushu aphakathi. Kwaye kwimeko yethu, eSpain, kulo nyaka sihlale ehlotyeni elona xesha lide lobushushu kunye nelona lishushu ngoJulayi kwimbali. Kungasichaphazela njani konke oku?
Umhlaba uyafudumala
Ubushushu bukazwe lonke Sele iyinto engathandabuzekiyo. Kusekho abantu ababuphikayo ubukho botshintsho lwemozulu kunye notshintsho kwindalo (njengoDonald Trump), kodwa le nto ingaphezulu kokucacileyo. Ukusukela ngeminyaka yoo-1950, iinguqu ezininzi ziye zaqatshelwa kwindalo esingqongileyo nakumaqondo obushushu ehlabathi. Umoya kunye neelwandle zifudumele, umthamo wekhephu kunye nomkhenkce ziyancipha ngendlela engazange ibonwe, ulwandle luyenyuka ... ziziphumo ngqo zolu hlobo lobushushu.
Kukho iingxelo ezikhutshwe ngu iQela loorhulumente kuTshintsho lweMozulu (IPCC) ye-UN apho zonke ezi rekhodi zibonakaliswa khona. Ingxelo yesihlanu yephaneli, enikezelwe ekupheleni kowama-2014, iqulethe idatha engundoqo esetyenziselwa zonke iingxoxo ezikhokelela kwingqungquthela yemozulu yaseParis. Kuyathenjwa ukuba esi siVumelwano saseParis siza kubonelela ngezikhokelo eziyimfuneko zokulwa nokutshintsha kwemozulu, nto leyo esele ibangela inkathazo nomonakalo kulo lonke iplanethi, izibonakalisa ngendlela yezehlo zemozulu ezimandundu ezifana nezo zichaphazela umhlaba. Ubushushu boLwandle lwaseTasman.
Ngokwenzululwazi Akukho zimpikiswano zokuphika ukufudumala kwaye akukho rhulumente emhlabeni othi ngenye indlela, ngoko ke, le yinyani yokwenyani. Ukongeza, i ukufudumala kwehlabathi kunye nemiphumo yako zibonakala kwiinkalo ezininzi zobomi bethu bemihla ngemihla. Iinkcukacha-manani ze ukufudumala eSpain ziyothusa kwaye zibonisa ukungxamiseka kokuthatha inyathelo.
Izenzo zomntu kwimozulu yeplanethi
Abantu banokuzibuza ukuba kutheni umhlaba ushushu. Kodwa impendulo ilula kakhulu: abantu kunye nemisebenzi yabo kukufudumala kwe-ecosystem. Abona nobangela baphambili bobushushu behlabathi kukukhutshwa kwerhasi yegreenhouse, ingakumbi kwicandelo lamandla, ezothutho kunye notshintsho kusetyenziso lomhlaba (iingxaki ezinxulumene nokugawulwa kwamahlathi, njengoko kuqatshelwe iimeko zembalela eSpeyin).
Kukho ezinye izizathu zendalo zokufudumala kwehlabathi, ezifana nentaba-mlilo, ukwahluka kwi-orbit yomhlaba kunye ne-axis, kunye nemijikelo yelanga. Nangona kunjalo, ezi mpembelelo zibonakala zincinci kakhulu kwimozulu yehlabathi. Ingxaki kukuba sikhupha i-CO2 eninzi kunokuba iplanethi inokwetyisa. Iingcali zenzululwazi ziqikelela ukuba i-carbon dioxide concentrations ifikelele kumanqanaba angazange abonwe kwiminyaka engama-800.000 edluleyo. Kwaye iingcali ezininzi zikhomba imfuneko ishiya isinye kwisithathu seoyile yesi sijikelezi-langa ingasetyenziswa, isiqingatha segesi kunye ne-80% yamalahle asafuna ukukhutshwa emathunjini oMhlaba ukuba sifuna ukuphepha ukufikelela kwindawo ebalulekileyo yokufudumala.
Iilwandle azikhuselekanga
Kukho imigaqo elawula imisebenzi kunye nokukhuselwa kweelwandle, nangona kunjalo, yi-3% kuphela yolwandle kunye nolwandle eyonwabela uhlobo oluthile lokhuseleko. Imisebenzi yabantu yokuloba ivelisa oko Iipesenti ezingama-90 zeentlanzi zehlabathi ziyingozi ngenxa yokuloba kakhulu.
Ngaphaya kweemayile ezingama-200 zoMmandla oQhelekileyo woQoqosho kwiLizwe ngalinye, iilwandle azikhuselwanga, ke ngoko, imisebenzi eyenziwayo apho ayilawulwa lulo naluphi na uhlobo lommiselo. Ukunciphisa le meko, ukuzibophelela kwamazwe aphesheya kukufikelela kukhuseleko I-10% yolwandle ngo-2020 kunye nama-30% ngowama-2030.
Ukongeza, ukufudumala kwehlabathi kubangela i-asidi kwiilwandle. I-IPCC iqikelela ukuba ukwanda kwe-CO2 ukusukela nge-1750 kubangele ukuba i-pH yaselwandle yehle ngeyunithi eziyi-0,1 ukusukela ngoko. Kwaye, nangona impembelelo kwintlobo-ntlobo zezinto eziphilayo ingakhange ifundwe ngokwaneleyo, kuyoyikwa ukuba le nkqubo ye-acidification nayo iya kugqiba ukohlwaya izilwanyana zaselwandle, njengoko kwenzekile iGreat Barrier Reef.
Njengoko sishwankathele kule posi, iziphumo zotshintsho lwemozulu ziyatshabalalisa ebomini bethu, yiyo loo nto kufuneka kuthathwe amanyathelo ukusombulula nokuphepha zonke ezi ngxaki.
