Peb raug kev puas tsuaj !!!!!

Tsis yog, txhua tus tau pib tham txog qhov teeb meem ntawm kev ua qias tuaj thiab lub ntiaj teb ua kom sov uas tua ntau lab tus neeg thiab hloov chaw, tab sis koj puas paub tias koj ib yam nkaus, yog koj, muaj kev pheej hmoo ploj mus, ib yam li lub ntiaj teb uas peb nyob, cia peb qhia rau koj vim li cas, , , Tom qab cov kws tshawb fawb tau hais tias hav zoov thiab cov suab puam Lub ntiaj teb cov txheej txheem tseem ceeb hauv ntiaj teb yuav dhau los ua "kev hloov pauv loj" nyob rau xyoo pua tom ntej vim kev hloov pauv huab cua.

Cov kev hloov pauv tau pib sau tseg nyob rau sab qab teb sab hnub poob Tebchaws Meskas, qhov chaw tua hluav taws loj tuaj hla thaj chaw loj ntawm hav zoov.

Nyob rau ib puas xyoo tom ntej los yog ib puas xyoo thiab ib nrab, cov kev hloov no yuav txuas mus rau cov nyom nyom (savanna) thiab cov suab puam, cuam tshuam rau cov txheej txheem tseem ceeb thiab hem tsiaj thiab nroj tsuag hauv Tebchaws Meskas thiab Europe tshwj xeeb, raws li kev tshawb fawb luam tawm hauv phau ntawv journal "Science. ".

Jonathan Overbeck, tus thawj coj ntawm Lub Tsev Kawm Ntawv ntawm Ib puag ncig thiab Sustainability tau hais tias "Yog tias kev hloov pauv huab cua tseem tsis tau tswj hwm, cov nroj tsuag hauv peb lub ntiaj teb yuav zoo li txawv ntawm qhov lawv ua niaj hnub no, uas ua rau muaj kev hem thawj loj rau ntau haiv neeg ntawm lub ntiaj teb," University of Michigan.

Txoj kev tshawb no yog ua raws li cov pob txha thiab cov ntaub ntawv ntsuas kub uas cuam tshuam txog ib theem uas tau pib 21 xyoo dhau los thaum kawg ntawm lub hnub nyoog dej khov kawg, thaum lub ntiaj teb kub nce los ntawm 4 txog 7 degrees Celsius.

Cov kws tshaj lij tau hais tias kev cia siab yuav tsum ceev faj, vim tias qhov sov sov thaum ub no yog vim muaj kev hloov pauv ntawm ntuj thiab lub sijhawm ntev dua.

Stephen Jackson, tus thawj coj ntawm Southwest Climate Adaptation Center ntawm US Geological Institute, tau hais tias, "Peb tab tom tham txog tib qhov kev hloov pauv uas tau tshwm sim dhau los ntawm kaum mus rau nees nkaum txhiab xyoo thiab tam sim no xav tias yuav tshwm sim hauv ib puas xyoo lossis ob." Ecosystems yuav tsum ua kom lawv yoog raws. "

Cov kev hloov pauv loj tau pom ntawm qhov nruab nrab thiab qhov siab siab hauv North America, Europe thiab yav qab teb South America. Cov cheeb tsam no yog npog nrog dej khov, thiab qhov kub thiab txias tau nce ntau dua li lwm tus nrog kev txhim kho ntawm kev nyab xeeb.

Tab sis yog tias tsis muaj kev siv zog, qhov tshwm sim yuav ntau dua 60%.

Qhov kev hloov no yuav tsis tsuas cuam tshuam rau hav zoov, tab sis kuj yog lub voj voog ntawm kev tsim dej.
