ʻO nā laʻana he nui o nā wā sultry i ka mōʻaukala kālaihonua e hāʻawi i nā hōʻailona.
Ke kūlana optimistic
E hoʻomaka me kahi hiʻohiʻona iʻoi aku ka maikaʻi.
Inā mākou e kāpae koke i ka unuhi ʻana o nā wahie fossil, e ʻano like ke aniau me nā wā hoʻomehana. Ua heleleʻi ka ua nui ma luna o ka Sahara, ʻoiai ua hōʻeha ʻia ʻo ʻAmelika Hema.
ʻO ka hana holoholona a me ka manu
No nā ʻano holoholona he nui a me nā manu, ua hōʻoia ʻia ia ʻano loli i kahi pilikia; pono e neʻe ke kaiaolaola holoʻokoʻa, alakaʻi ʻia e nā māla magnet, e hoʻololi i ke ola. Ua ola wale nō nā bea Polar ma muli o ke aloha o nā lua pele i ka Arctic nui loa. ʻO nā ulu lāʻau ʻoka a me nā lāʻau eucalyptus mai ka hema o ka Appalachians i neʻe i ke kaona o ka ʻākau o NūIoka, ʻoiai ʻo nā holoholona ʻApelika e like me nā ʻelepani a me nā hippos i huakaʻi ma waena o ʻEulopa ma ke ala like.
Minamina, i kēia manawa ma nā ala o nā neʻe hiki ke hiki mai i laila nā kūlanakauhale, nā alanui a me nā mea keakea ʻē aʻe, a me ka ʻoi aku o ke kalapona kalapona i loko o ke kai, ʻaʻole e ʻae i nā mollusks e neʻe i kahi ʻē aʻe, no ka mea, ke ulu wikiwiki nei ka ʻawa o nā wai kai Eia kekahi, ʻo nā ʻenekini i hana ʻia e nā kānaka e hana i kahi hopena hale hoʻomehana, kahi e mālama ai i ka wela i ʻoi aku ka ikaika a me ka lōʻihi, ma ke kauoha o 100,000 mau makahiki.
ʻOiai ʻo kahi wānana optimistic e lawe i nā pilikia nui, akā ʻo ka mōʻaukala o kā mākou honua e hōʻoia i ka hiki ʻole. Ua hana ʻia kahi pōpilikia like ma kahi o 56 miliona mau makahiki i hala aku nei a ua kapa ʻia ʻo Late Paleocene thermal maximum.
ʻAʻole like me ka hoʻomehana interglacial haʻahaʻa i kū ma muli o ke kuli, wobble a me ka orbit o ka Honua, ua hoʻololi ka PTM i ka honua ma mua o ka ʻike ʻia. ʻO ke kūpona o ka carbon dioxide i mau manawa ke kiʻekiʻe ma mua o kēia lā, a hui pū ʻia me ka hoʻomehana ʻana a me ka hōʻiliʻili ʻana o carbon dioxide i loko o nā wai kai, ʻo kēia ka hopena o ka luku ʻia ʻana o nā meaola kai a me ka hoʻopau ʻia ʻana o nā waihona limu ma ka papakū.
ʻO ka moana a me ka Antarctica
Ua lilo ka Moana Arctic i loko o ke kai kūʻono me ka wai mehana, i hoʻopuni ʻia e ka nahele lau nahele. Uhi ʻia ʻo Antarctica me nā kumulāʻau beech, a ua hoʻopiha ʻia ke kahakai me ka silt mai nā ua nui mau.
Inā kū hou kēia, a hoʻoheheʻe ka hau a pau o ka honua, piʻi ka pae o ka wai o ka honua 60 mika.
