Izithombo ze-oki ezibomvu e-Central Park zikhula ngokushesha izikhathi eziphindwe kasishiyagalombili kunezabazali bazo ezitshalwe ngaphandle kwedolobha, mhlawumbe ngenxa yomphumela “wesiqhingi sokushisa” sasemadolobheni, Abacwaningi base-Columbia University bayabika.
Abacwaningi batshala izithombo ze-oki ebomvu yomdabu entwasahlobo ka-2007 no-2008 ezindaweni ezine: enyakatho-mpumalanga yeCentral Park, eduze ne-105th Street; ezindaweni ezimbili zehlathi e-suburban Hudson Valley; futhi eduze ne-Ashokan Reservoir yedolobha esezintabeni zaseCatskill cishe ngamamayela ayi-100 enyakatho yeManhattan. Ekupheleni kwehlobo ngalinye, izihlahla zedolobha zase zifake i-biomass ephindwe kasishiyagalombili kunaleyo ekhuliswe ngaphandle kwedolobha, ngokocwaningo lwazo, olushicilelwe kumagazini i-Tree Physiology.
"Izithombo zakhula kakhulu edolobheni, nokuncipha kokukhula njengoba usuka kude nedolobha," kusho umlobi ohamba phambili walolu cwaningo, uStephanie Searle, owayeneziqu ze-Columbia University ngesikhathi kuqala ucwaningo futhi manje ungumcwaningi wenqubomgomo ye-biofuels esikoleni. I-International Council on Clean Transportation eWashington.
Abacwaningi bacabanga ukuthi amazinga okushisa aseManhattan - afinyelela kumadigri ayisishiyagalombili aphezulu ebusuku kunasendaweni yasemaphandleni - kungaba isizathu esiyinhloko samazinga okukhula okusheshayo e-Central Park.
Nokho izinga lokushisa ngokusobala ngomunye kuphela umehluko phakathi kwezindawo zasemakhaya nasemadolobheni. Ukuze bahlukanise indima edlalwa i-thermostat, abacwaningi baphinde baphakamisa ama-oki endaweni yaselabhorethri lapho zonke izimo zazifana ngokuyisisekelo, ngaphandle kwezinga lokushisa, elashintshwa ukuze lilingise izimo ezivela ezindaweni ezihlukahlukene zensimu. Ngokuqinisekile, babona amazinga okukhula okusheshayo kwama-oki akhuliswe ezimweni ezishisayo, afana nalawo abonwa ensimini, kusho uDkt. Searle.
Okubizwa ngomphumela wesiqhingi sokushisa sasemadolobheni kuvame ukuxoxwa ngakho mayelana nemiphumela engase ibe mibi. Kodwa ucwaningo luphakamisa ukuthi kungaba usizo ezinhlotsheni ezithile. "Ezinye izinto eziphilayo zingakhula kahle ezimweni zasemadolobheni," kusho omunye umbhali, uKevin Griffin, isazi sokusebenza kwezihlahla eLamont-Doherty Earth Observatory e-Columbia, esitatimendeni.
Imiphumela ihambisana naleyo ye-a 2003 isifundo seMvelo eyathola amazinga okukhula amakhulu phakathi kwezihlahla zikabhabhulini ezikhuliswe edolobheni kunalezo ezitshalwa ezindaweni ezizungezile. Kodwa ucwaningo lwamanje luye lwaqhubekela phambili ngokuhlukanisa umphumela wokushisa, kusho uDkt. Searle.
Ama-oki abomvu nezihlobo zawo zibusa emahlathini amaningi ukusuka eVirginia kuya eningizimu yeNew England. Okuhlangenwe nakho kwama-oki abomvu aseCentral Park kungase kuveze izinkomba zalokho okungenzeka emahlathini kwenye indawo njengoba amazinga okushisa ekhuphuka emashumini eminyaka ezayo nokushintsha kwesimo sezulu kusengaphambili, abacwaningi basikisela.
