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 (I-IPCC, kwisifinyezo sayo kwisiNgesi) se-UN apho zonke ezi rekhodi ziboniswa. Kwingxelo yesihlanu yeli qela, ebelinikezelwe ekupheleni konyaka ka-2014, uyakufumana ulwazi oluphambili olusetyenziselwa lonke uthethathethwano lwengqungquthela yemozulu yaseParis. Kuyathenjwa ukuba izikhokelo eziyimfuneko ziya kuvela kwesi siVumelwano saseParis ukuze sikwazi ukulwa nokutshintsha kwemozulu, esele ibangela isiphithiphithi nomonakalo kuzo zonke iindawo zeplanethi, izibonakalalisa ngohlobo lweziganeko zemozulu ezigqithisileyo.
Ngokwenzululwazi Akukho zimpikiswano zokuphika ukufudumala kwaye akukho rhulumente emhlabeni othi ngenye indlelaKe ngoko, oku kuyinyani.
Izenzo zomntu kwimozulu yeplanethi
Abantu banokuzibuza ukuba kutheni umhlaba ushushu. Kodwa impendulo ilula kakhulu: abantu kunye nemisebenzi yabo batshisa ubume bendalo. Oonobangela abaphambili bokushushubeza komhlaba kukukhutshwa kwegesi yendlu eluhlaza, ngakumbi kwicandelo lezamandla, ezothutho notshintsho kusetyenziso lomhlaba (iingxaki ezinxulumene nokugawulwa kwamahlathi).
Kukho ezinye izinto ezibangela ukufudumala kwehlabathi kwemvelaphi yendalo enje nge-volcanism, umahluko kumjikelezo woMhlaba kunye ne-axis okanye imijikelezo yelanga. Nangona kunjalo, ezi mpembelelo azibonakali kwimeko yemozulu yehlabathi. Ingxaki kukuba sikhupha ngaphezulu i-CO2 kunokuba iplanethi inako ukwetyisa. Iingcali zenzululwazi zibonisa ukuba i-carbon dioxide concentrations ifikelele kumanqanaba angazange abonwe ngaphambili kule minyaka ingama-800.000 idlulileyo. Kwaye iingcali ezininzi zikhomba kwimfuno yokushiya isithuba esingaxutywanga sesithathu seoyile yeplanethi, isiqingatha segesi kunye ne-80% yamalahle aseleyo ukuba akhutshwe emathunjini omhlaba ukuba kukuthintela ukufikelela indawo ebalulekileyo yokufudumeza.
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 ifuthe kwindalo engafaniyo ingakhange ifundwe ngokwaneleyo, kuyasoyikiswa ukuba le nkqubo yokufakwa kweasidi iyakugqibela ukohlwaya iintlobo zaselwandle.
Njengoko sishwankathele kule posi, iziphumo zotshintsho lwemozulu ziyatshabalalisa ebomini bethu, yiyo loo nto kufuneka kuthathwe amanyathelo ukusombulula nokuphepha zonke ezi ngxaki.
