Kei te whakaatu a CO2, ahakoa i whakaparahuatia hei mate o ngā rā hou, he toto ora mō te whakahoutanga taiao ā-ao.
Kua whakaatu ngā kairangahau nō Te Whare Wānanga o Málaga me te Kaunihera Rangahau ā-Motu o Hapanihi i ā rātou
rangahau kua piki nui te tipu otaota ki te 38 ōrau o te mata whenua o tō tātou ao i roto i ngā tekau tau kua pahure.
Neke atu i te toru hauwha o ēnei panonitanga he wikitoria nō te taiao:
Kei te whakawhānui ngā ngahere, kei te puāwai ngā papa otaota, kei te hoki whakamuri ngā koraha.
I whakaatu tētahi rangahau a NASA i te tau 2016, ko te pānga whakatipu o te CO2 te kawenga mō te 70 ōrau o te kākāranga
o te ao – e kitea ana ngā whanaketanga pai puta noa i te ao.
Heoi, kāore tēnei rangahau e whakaarohia ana hei kaupapa pāpāho e ngā pāpāho matua.
Ko te mea pea nā te mea ka tohu i te mutunga o te pakihi whai hua CO2, e whakamahia ana hei tikanga whakatumatuma
i roto i te kaupapa āhuarangi ā-ao a te WEF me te UN.
