Sisemngciphekweni wokutshatyalaliswa!!!!!!

Hayi, wonke umntu waqala ukuthetha ngengxaki yongcoliseko kunye nokufudumala kwehlabathi okwabulala izigidi zabanye abantu, kodwa uyazi ukuba nawe, ewe, usesichengeni sokunyamalala, njengokuba ihlabathi esikulo, sikuxelele ukuba kutheni ,, Emva kokuba izazinzulu zithe amahlathi kunye neentlango Iinkqubo ezisisiseko ezibalulekileyo zehlabathi zinokungena "utshintsho olukhulu" kwinkulungwane ezayo ngenxa yokutshintsha kwemozulu.

Utshintsho luye lwaqalisa ukurekhodwa kumzantsi-ntshona weUnited States, apho imililo emikhulu ihlasela imimandla emikhulu yamahlathi.

Kwinkulungwane elandelayo okanye inkulungwane enesiqingatha, olu tshintsho luya kunabela kumathafa anengca (savanna) kunye neentlango, ezichaphazela iinkqubo ezibalulekileyo kunye nezilwanyana ezisongelayo kunye nezityalo eUnited States naseYurophu ngokukodwa, ngokutsho kophando olupapashwe kwiphephancwadi "Isayensi ".

"Ukuba utshintsho lwemozulu luhlala lungalawuleki, izityalo ezikwihlabathi lethu ziya kujongeka zahluke kakhulu kwinto eziyenzayo namhlanje, nto leyo ebeka isoyikiso esikhulu kwiyantlukwano yehlabathi," utshilo uJonathan Overbeck, umphathi weSikolo seNdalo kunye noZinzo. kwiYunivesithi yaseMichigan.

Uphononongo lusekelwe kwiifosili kunye neerekhodi zobushushu ezinxulumene nesigaba esaqala kwiminyaka engama-21 eyadlulayo ekupheleni kwe-Ice Age yokugqibela, xa ubushushu boMhlaba benyuka nge-4 ukuya kwisi-7 ngokukaCelsius.

Iingcali zigxininise ukuba ukulindela kulumkile, kuba oku kufudumala kwamandulo kubangelwa ukuguquguquka kwendalo kunye nexesha elide kakhulu.

UStephen Jackson, umalathisi weSouthwest Climate Adaptation Centre yeUS Geological Institute, wathi, “Sithetha ngomlinganiselo ofanayo wotshintsho olwenzeka ngaphambili kwisithuba seminyaka elishumi ukuya kumashumi amabini amawaka kwaye ngoku kulindeleke ukuba lwenzeke kwisithuba senkulungwane okanye Mbini." Ii-ecosystems kufuneka zikhawulezise ukuziqhelanisa nazo.”

Izazinzulu zicinga ukuba umsebenzi wabo, owenziwe ngesiseko sedatha ethathwe kwiindawo ezimalunga nama-600, ngowona ubanzi kakhulu kule ntsimi. Yayiquka onke amazwekazi ngaphandle kweAntarctica.

Olona tshintsho lukhulu lujongwe kwiindawo eziphakamileyo neziphakathi kuMntla Melika, eYurophu nakumazantsi oMzantsi Melika. Le mimandla igutyungelwe ngumkhenkce, kwaye ubushushu buye banda ngaphezu kwezinye ngophuhliso lwemozulu.

Oososayensi banikela ingxelo yokuba ukuba ukukhutshwa kwegesi yegreenhouse akudluli kwisilingi esikwiSivumelwano saseParis sika-2015, “amathuba okuba uhlaza lutshintshe ngomlinganiselo omkhulu luya kuba ngaphantsi kwama-45%. Kodwa ukuba akukho migudu eyenziwayo, amathuba aya kuba ngaphezu kwama-60%.

Olu tshintsho aluyi kuchaphazela kuphela amahlathi, kodwa kunye nomjikelo wokubunjwa kwamanzi.
