Yakakwira kabhoni dhayokisaidhi iri kukonzera matambudziko mazhinji kuvanhu, sezvo iwo achiwedzera iyo greenhouse maitiro. Nekuda kweizvozvo, tembiricha inokwira uye mapango anonyungudika, izvo zvinogona kuisa mungozi hupenyu hwakawanda.
Imwe yenzvimbo dziri kuongororwa iAlaska, kunyanya iyo tundra. Kubva muna1975 kusvika parinhasi huwandu hweEC2 iyo yakaburitswa nekuda kweiyo nyowani yakawedzera ne70%, sezvakataurwa neNational Aeronautics uye Space Administration, inozivikanwa nechidimbu chayo muChirungu NASA.
Chidzidzo ichi, icho chave kutungamirwa neHarvard University mamiriro ekutsvagisa Roisin Commane, zvinoratidza izvo tembiricha inodziya uye chando chinonyunguduka zvinogona kuwedzera kabhoni dhayokisaidhi mune tundras, izvo pasina mubvunzo zvichakanganisa kudziya kwepasirese sezvo ivhu riri pamusoro pemadhigirii makumi matanhatu ekuchamhembe kwenharaunda riine yakawanda kabhoni iri muchimiro chezvinhu zvakasikwa kubva kuhuswa hwakafa.
Comanne akatsanangura izvo Munguva yechando chearctic, ivhu rinonyungudika uye hutachiona hunoputsa ichi chinhu chehupenyu, chichigadzira huwandu hwakawanda hweEC2. Kunyangwe muna Gumiguru ivhu rinotonhora zvakare, kuburitsa kwakasimba kwechinhu ichi kunoenderera kudzamara ivhu ragwamba zvachose.
Naizvozvo, mamiriro ekunze ari kuramba achidziya izvo zvakonzera kuti tundra itore kusvika kumwedzi mitatu kuti itonhorere zvakareKana kare zvaingotora mwedzi chete. Uye zvakare, iyo data yakawanikwa mune yekucherechedza shongwe inoratidza inogara ichiwedzera muacarbon dioxide, izvo zvinoita kuti tembiricha mumatsutso nemuchando dziwedzere.
Nekudaro, iyo ivhu reiyo tundra inoshanda sechiwedzeredza shanduko yemamiriro ekunze.
