I-NASA ibikezela isiphetho esibuhlungu seplanethi enguMhlaba

Abacwaningi e-United States nase-Japan benza ucwaningo lwesayensi, imiphumela yalo eveze ukuthi iplanethi ingase iphelelwe umoya-mpilo ngemva kweminyaka engaba isigidigidi, okusho ukuthi Qeda iphile.

Emininingwaneni, ososayensi base-United States nase-Japan bahlawumbisela ukuthi izinga lokushisa lelanga lingakhuphuka, okuzoholela ekushiseni okuphezulu komkhathi, kuphazamise ukusebenza kwe-carbon dioxide, ezokwenza izitshalo zingakwazi ukukhiqiza umoya-mpilo, ngokusho kwe Ucwaningo olwenziwa ngaphakathi kohlaka lohlelo lwe-American Space Agency "NASA" futhi lwashicilelwa kumagazini we-"Nature Geoscience".

Ngemuva kweCorona, i-asteroid enkulu ishayisana noMhlaba futhi isongela ukuphila kuwo

izingxenye ezimbili eziyinhloko

Nakuba kwaziwa ukuthi umoya-mpilo ne-nitrogen yizici ezimbili eziyisisekelo zomkhathi womhlaba, umoya-mpilo ukhona emkhathini ngenqubo ye-photosynthesis eyenziwa izitshalo.

Ucwaningo luphinde lubonise ukuthi, lapho kungabikho ukuphila kwezitshalo, umoya-mpilo abantu nezilwane okudingeka bawuphefumule uzophela, ugcizelele ukuthi ukususwa komoya-mpilo esikhathini esizayo kuwumphumela ongenakugwemeka wokwanda kokukhanya kwelanga.

Ngaphezu kwalokho, ngokusho kwewebhusayithi ye-Science Times, njengoba isimiso sethu sonozungezilanga siguga, ilanga lizoshisa kakhulu, futhi ukwanda kokukhiqizwa kwamandla elanga kuzofudumeza umkhathi woMhlaba, futhi amazinga e-carbon dioxide azokwehla.
