Ngokuqinisekileyo uqaphele ukuba kwiminyaka yakutshanje kukho imithi, enjengemalmond, eqhakaza ngaphambi kwexesha layo. Oku, kunokuba ngumboniso omangalisayo, kunokubabangela inkathazo enkulu xa iqabaka libetha, ngesizathu esilula sokuba iiseli ezenza iipetali azimeli kumaqondo obushushu asezantsi. Kwaye ukuba azikho iintyatyambo, akunakubakho ziqhamo.
Utshintsho lwemozulu luzisa intwasahlobo phambili, kodwa yintwasahlobo eneempawu eziqhelekileyo zobusika, oko kukuthi: iveki enye ithemometha ingafunda amashumi amabini ama-degrees Celsius, kodwa ngolunye usuku yehle iye kwiidigri ezintlanu okanye ezintandathu ezibulala uqhambuko. ithenda ngakumbi. Ke, iziqhamo zezityalo zisengozini.
Ngokophando olushicilelwe kwiphephandaba Nature Communications, izityalo eYurophu kangangeminyaka engama-30 ziphinde zaqala ukukhula kwithuba leentsuku ezintathu ngaphambili kwaye ziphela ebusika. Olu tshintsho lubaveza kwiqabaka yasentwasahlobo, kuxa iintyatyambo namagqabi zidubula. Yiyo loo nto, xa kukho iqabaka, kungasathethwa ke ngekhephu, ziye zibuthathaka kakhulu, kangangokuba iintyatyambo ziyaphuma kwaye amagqabi ayatsha, okanye awe ngqo, apho isityalo sinyanzeliswa ukuba sisebenzise amandla kwakhona ukuvelisa entsha.
Um-amangile usuka egadini yam. Ifoto ethathwe ngoJanuwari 20, 2018. Iqale ukuqhakaza nge-8 yaloo nyanga.
Kunoko, e-Asiya nakuMntla Melika inani leentsuku zezityalo ezinengxaki yeqabaka liyehla, kodwa hayi kuba ezo ndawo ziyaphola kodwa kuba ukufudumala kwehlabathi kuye kwanciphisa inani leentsuku zonyaka apho iqabaka lenzeka khona. Nangona kunjalo, kuye kwakho iziqendu apho le ntwasahlobo ineziphumo ezibi kakhulu: ngo-2007 bekukho iveki yamaqabaka entwasahlobo embindini nasempuma e-United States anciphise imveliso yengqolowa nge-19%. iipesika ezingama-75% kunye nama-apile kunye nama-walnuts angama-66%.
