Umkhathi weplanethi yethu uMhlaba wakhiwe ngamagesi ahlukahlukene, njenge-oxygen, i-nitrogen, i-argon, i-ozone nomhwamuko wamanzi. Bonke badlala indima ebaluleke kakhulu esimweni sezulu seMhlaba, ngakho-ke empilweni ekhona kuye.
Uma sikhuluma ngokushintsha kwesimo sezulu, kwesinye isikhathi kunganikeza umuzwa wokuthi i-carbon dioxide iyigesi engaba yingozi, futhi kunjalo, kepha kuphela esimweni lapho abantu beqhubeka nokungcolisa njengoba benza, ngoba ukukhishwa, lapho bezobamba ukushisa okukhulu futhi kuphakame amazinga okushisa. Manje, I-NASA idale ividiyo lapho kubonakala khona ukusebenza kwe-CO2 ekhaya lethu.
Ososayensi be-NASA basebenzise ukubonwa okuvela kusathelayithi i-Orbiting Carbon Observatory (OCO-2) ukwenza imodeli yokuziphatha kwekhabhoni kusuka ngoSepthemba 1, 2014 kuya ku-Agasti 31, 2015. Lesi yisibonelo esingasetshenziswa ukubikezela lapho ukugxila kuzoba phezulu noma phansi.
Ngemuva kokufunda ukukhishwa kwe-CO2 amashumi eminyaka, Ochwepheshe manje sebengaqoqa yonke le datha ukudala ukucacisa okuphezulu kwe-3D lokho kuvumela noma yimuphi umsebenzisi ukuthi azi ukuthi le gesi iziphatha kanjani emkhathini.
I-Carbon dioxide isebenza njenge-thermostat. Ukuphakama kokuhlushwa, ukushisa okuningi kuzobambeka ngaphakathi kweplanethi, okuzosheshisa ukufudumala kwembulunga yonke. Ngakho-ke, Kubalulekile ukuqonda ukuthi yiziphi izindawo ezimunca i-CO2 kakhulu nokuthi zingakanani.
Le vidiyo ikhombisa ukukhuphuka nokuwa kwe-CO2 eNyakatho Nenkabazwe unyaka wonke; ithonya lamazwekazi, izintaba, nemisinga yolwandle kumaphethini wesimo sezulu; kanye nomthelela wesifunda we-photosynthesis.
