I-tundra ngumthombo omuhle kakhulu we- i-carbon... Okungenani kwaba. Kulezi zinsuku, umthamo wayo wokugcina ulimale kabi, ngenxa yokwanda kwezinga lokushisa: the izinto eziphilayo ophilayo bakhipha i-CO2 eyengeziwe emkhathini, kuyilapho inqubo yokubamba i-photosynthetic ithinteka emazingeni athile.
Ngokushintsha kwesimo sezulu, izimila nezinto eziphilayo zingakhipha okuningi i-carbonngesimo se- isikhutha noma i-methane, kunalokho abengakugcina. Sekuyiminyaka engaphezu kweyishumi manje abacwaningi bemile esiteshini sokucwaninga se- Zakenberg, enyakatho yeGreenland, hlola ibhalansi yekhabhoni yayo yonke indawo inkabazwe enyakatho.
Ocwaningweni olushicilelwe ephephabhukwini Journal of Research Geophysical, iqembu eliholwa ngu Magnus ILund kukhombisa ukuthi ukukhishwa kwe-CO2 okubangelwa izinto eziphilayo kuyanda njengoba izinga lokushisa likhuphuka.
Ukusetha ukulinganisela kwekhabhoni tundra, ososayensi bafunde izindlela ezimbili: izinga lekhabhoni elikhishwe ngendlela ye- CO2 ukuphefumula, kanye nezinga eligcinwe yizitshalo nge i-photosynthesis. Ukusuka kulezi zindlela ezimbili, kungenzeka ukunquma ukuthi ngabe i-tundra ingumthombo noma ngumthombo we i-carbon.
El ukutadisha kukhombisa ukuthi ukukhishwa kwe-CO2 okubangelwa ukuphefumula kwezilwane kukhuphuka ngokulandelana ne- lokushisa. Ngakolunye uhlangothi, umthamo wesitoreji sekhabhoni ohlobene ne- i-photosynthesis kuncipha njengoba izinga lokushisa landa. Ngokusobala lokhu isitoreji kuyaphela lapho lokushisa idlula u-7ºC.
Imininingwane engaphezulu - I-Google yenze i-carbon footprint yayo ibe sesidlangalaleni
