Ko ngā momo haurehu ka aukati i te pōkākā ka whakaatangia e Papatūānuku, kia kore ai e puta noa atu ki tuarangi. Mā konei e hua ake ai te kati mahana e whakamahana nei i tō tātou ao. Nā te mahi a te tangata ki te tahu koranehe, nā ngā tukanga ahumahi maha, kua nui haere ngā haurehu kati mahana, me te aha, kua mahana haere te ao. Ko te wairehu (H2O), te hauhā (CO2), te mewaro (CH4), te hauota-rua ōkai (N2O), me te mākōwaro (CFC) ngā haurehu kati mahana matua.
The gases in the atmosphere that block the infrared radiation from the Earth, so that it doesn't dissipate into space. This gives rise to the greenhouse effect which warms the Earth’s surface. Human activity in burning fossil fuel and creating many industrial processes has resulted in an increase of greenhouse gases in the atmosphere, giving rise to global warming. Water vapour (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and chlorofluorocarbons (CFCs) are the main greenhouse gases.
haurehu - gas
kati - close in, barrier, trap
mahana - warm
He aha i nui haere ai ngā haurehu kati mahana o te kōhauhau i te rautau kua pahure nei?
Ko te ruapara, te pāmu miraka kau, me ngā waka tahu koranehe ētahi takenga matua o te haurehu kati mahana.
Ko ngā whenua whairawa o te rātō ngā tino kaiwhakaputa haurehu kati mahana.
