Ososayensi bathole ukuthi izikhungo zokuphehla ugesi ophehlwa ngamanzi nezinqolobane ezisetshenziselwa ukukhiqiza ugesi nezinhlelo zokunisela zikhiphela amagesi abamba ukushisa emkhathini, okunomthelela ekufudumaleni kwembulunga yonke. Izitshalo zamandla kagesi zikhiqiza u-1.3% womoya ongcolile, ophakeme kaningana kunokujwayelekile.
Ngesikhathi kwakhiwa ichibi, umhlaba omusha ugcwala amanzi futhi inhlabathi ilahlekelwe yimithombo yayo yomoya-mpilo. Njengoba ukwakhiwa kwamadamu kukhula manje, inani lokukhishwa kwe-methane liyanda.
Lokhu okutholakele kwenziwa ngesikhathi, ngoba umphakathi womhlaba uzokwamukela isivumelwano mayelana nokuhlukaniswa komnotho ngomnotho, okusho ukuthi inani lezikhungo zokuphehla ugesi ophehlwa ngamanzi lizokhula. Mayelana nalokhu, umsebenzi omusha uvele konjiniyela bamandla nakwezemvelo: indlela yokusebenzisa imithombo yamanzi ukukhiqiza amandla ngaphandle kokulimaza imvelo.
