<prompt> Fingqa isihloko: Izinkulungwane zamakhilomitha-skwele ehlathi lemvula liyasuswa e-Amazon unyaka ngamunye ukuze kwenziwe indawo yokulima - indlela yokucekela phansi eyenzeka emhlabeni wonke. Kodwa naphezu kwalokhu, iplanethi iye yaba luhlaza kakhudlwana kule minyaka eyishumi edlule, njengoba inani lezitshalo ezimboza umhlaba liye landa. Lokhu kwanda kuphawuleka kangangokuthi izihlahla nezitshalo emhlabeni wonke manje zigcina cishe amathani ayizigidi eziyizinkulungwane ezine ekhabhoni engeziwe kunalawo ezawagcina ngo-2003. Izinkulungwane zamakhilomitha-skwele ehlathi lemvula liyasuswa e-Amazon esithombeni unyaka ngamunye ukuze kwenziwe indawo yokulima - umkhuba wokubhujiswa okwenzeka emhlabeni wonke - kodwa naphezu kwalokhu, iplanethi iye yaba luhlaza kakhudlwana kule minyaka eyishumi edlule, ngenani eliphelele lokumbozwa kwezitshalo likhuphuka jikelele. Lokhu kubangelwa ukutshala izihlahla eChina, ukuhluma kabusha kwamahlathi emazweni ayengaphansi kweSoviet ngenxa yamapulazi ashiywe dengwane, nama-savanna aluhlaza ngokwengeziwe ngenxa yemvula eningi. Ososayensi bahlaziye iminyaka engu-20 yedatha yesathelayithi futhi bathola ukwanda kwekhabhoni, naphezu kokuqedwa kwamahlathi amakhulu asezindaweni ezishisayo eBrazil nase-Indonesia, ngokusho kocwaningo olushicilelwe ngoMsombuluko ku-Nature Climate Change. Ikhabhoni ihamba phakathi kwezilwandle zomhlaba, umoya nomhlaba. Itholakala emkhathini ngokuyinhloko njenge-carbon dioxide CO2 - igesi eyinhloko eshintsha isimo sezulu - futhi igcinwe njenge-carbon ezihlahleni. Ngokusebenzisa i - photosynthesis, izihlahla ziguqula i - carbon dioxide ibe ukudla ezikudingayo ukuze zikhule, zibambe i - carbon ezinkuni zazo. Umhlaba uya uhlaza ngenxa yokutshalwa kwezihlahla eChina, ukuvuselelwa kwamahlathi emazweni ayengaphansi kweSoviet ngenxa yamapulazi ashiywe dengwane kanye nama-savanna aluhlaza ngokwengeziwe ngenxa yamapulazi ashiywe dengwane nemvula eningi. Kuboniswa isithombe somndeni osebenza ngokuhlanganyela kwezolimo e-USSR ngo-1935. Abacwaningi bathi uMhlaba uya uhlaza ngenxa yokuhlanganiswa kwezinto ezingokwemvelo nezingokwezimali. Kunezihlahla eziningi eChina ngenxa yezinhlelo zokutshala eziye zasebenza amashumi ambalwa eminyaka. Izitshalo ziye zanda emathafeni ase - Australia, e - Afrika naseNingizimu Melika ngenxa yokwanda kwemvula...  <response>: Ososayensi e - Australia bahlaziya iminyaka engu - 20 yemininingwane yesathelayithi ephathelene nokuluhlaza. Kutholakale ukuthi kunamathani ayizigidi eziyizinkulungwane ezingu-4 ekhabhoni enqwabelene ezihlahleni kunalawo ayengo - 2003. Ukutshala izihlahla eChina, ukuvuselelwa kwamahlathi emazweni ayengaphansi kweSoviet kanye ne-Savannah evundile ngenxa yemvula eningi kukholakala ukuthi kubangela lokhu kwanda.
