Qhov kub thiab qhuav tsis tshua muaj tshwm sim qhia txog sab txaus ntshai tshaj plaws.
Thawj qhov yog Tebchaws Europe, ntxiv rau qhov teeb meem zaub mov. Daim ntawv tshaj tawm tshiab los ntawm Fabkis lub tuam txhab kev sab laj ua liaj ua teb loj Strategie Grains xav tias EU cov pob kws tsim khoom yuav poob mus rau 55.4 lab tons hauv lub caij qoob loo xyoo 2022-2023, tej zaum qib qis tshaj plaws hauv 15 xyoos, poob ntau dua 20 feem pua ntawm ib xyoos dhau los. Thaum lub caij nplooj zeeg thiab lub caij ntuj no xyoo 2022, cov nqi zaub mov eu tuaj yeem nce siab dua.Cov Teeb Meem Me Me, Cov Txuas Idc thiab Cov Teeb Ci Rau Lub Log Tsheb Kauj Vab yuav tsum tau sau tseg.
Lub Chaw Tshawb Fawb Sib Koom Tes ntawm European Commission tau ceeb toom tias Tebchaws Europe yuav raug kev kub ntxhov phem tshaj plaws hauv kwv yees li 500 xyoo. Nyias muaj nyias, Aschbacher, tus thawj coj ntawm European Space Agency, tau hais tias yog tias kev hloov pauv huab cua tsis raug saib xyuas, Tebchaws Europe yuav raug nqi kaum txhiab lab daus las hauv lub xyoo pua no.
Tej zaum qhov kev pheej hmoo loj tshaj plaws rau qhov kub thiab txias heev hauv Tebchaws Europe yog tias qhov nrawm ntawm kev yaj ntawm Arctic glaciers tab tom nrawm dua. Lub sijhawm hauv zos rau lub Yim Hli 11, Washington post tau hais txog kev sib txuas lus ntuj - lub ntiaj teb thiab ib puag ncig, kev tshawb fawb tshiab kawg tau hais tias qhov kub thiab txias arctic sai dua li ntau tus kws tshawb fawb xav tau, arctic yog ib qho ntawm thaj chaw kub thiab txias tshaj plaws hauv ntiaj teb, thaum kawg ntawm Lub Xya Hli, Arctic Svalbard 40 billion tons ntawm dej khov tau yaj mus rau hauv dej hiav txwv.
Tebchaws Meskas kuj tab tom ntsib teeb meem qhuav heev. Raws li cov ntaub ntawv tshiab kawg los ntawm US Drought Monitor, 55 feem pua ntawm sab hnub poob ntawm Tebchaws Meskas tam sim no siab dua qib qhuav heev. Ntau lub chaw xov xwm hauv Tebchaws Meskas tau hais tias qhov no yog qhov qhuav tshaj plaws hauv kev tsim tsa ntau tshaj 200 xyoo.
Tebchaws Europe mam li nco dheev "ua lub tswb ceeb toom"
Qhov kub thiab txias tsis tshua muaj thiab huab cua qhuav ua rau kev kub ntxhov zaub mov hauv Tebchaws Europe hnyav zuj zus.
Daim ntawv tshaj tawm tshiab los ntawm lub tuam txhab kev sab laj ua liaj ua teb loj hauv Fabkis Strategie Grains kwv yees tias kev tsim cov pob kws hauv EU yuav poob mus rau 55.4 lab tons hauv lub caij cog qoob loo xyoo 2022-2023, tej zaum yog qib qis tshaj plaws hauv 15 xyoos, nrog rau kev poob qis ntau dua 20 feem pua txhua xyoo. Qhov kev kwv yees poob qis 15 feem pua ntawm 65.4 lab tonnes hauv lub Xya Hli, qhia txog kev hem thawj ntawm kev qhuav.
Daim ntawv tshaj tawm hais tias qhov kev cia siab rau xyoo 2022 cov pob kws sau thoob plaws Tebchaws Europe tab tom poob qis heev, thiab yuav poob qis tshaj plaws txij li xyoo 2007.
Qhov kev cia siab rau lwm cov qoob loo kuj tsis zoo. Strategie Grains kwv yees tias tag nrho cov qoob loo EU yuav poob 8.5 feem pua hauv lub caij qoob loo 2022-2023. Ntawm lawv, kev tsim cov nplej mos mos yuav poob 5 feem pua mus rau 123.3 lab tons, thaum kev tsim cov barley yuav poob 3.7 feem pua mus rau 50 lab tons, ob qho tib si qis dua qhov nruab nrab tsib xyoos.
Qhov laj thawj rau qhov kev poob siab zoo li no yog vim qhov kev kub ntxhov tsis tshua muaj no tau cuam tshuam rau yuav luag txhua lub tebchaws EU uas muab zaub mov tseem ceeb: Fabkis, Spain, Ltalis, Lub Tebchaws Yelemees, thiab lwm yam, nyob rau sab hnub poob thiab sab qab teb-nruab nrab Tebchaws Europe, uas tsis muaj nag ntau rau yuav luag ob lub hlis.
Cov neeg ua liaj ua teb Italian hais tias cov noob cog qoob loo tab tom tuag thiab tuag thaum huab cua kub thiab qhuav, tsim tau tsuas yog 30 feem pua ntawm xyoo tas los.
Spain, uas muab 50% ntawm cov roj txiv roj thoob ntiaj teb, tsis muaj kev zam. Tus Thawj Kav Tebchaws Mev Luis Planas tau ceeb toom tias xyoo no cov txiv roj sau yuav qis dua li xyoo dhau los, thiab kwv yees tias kev tsim cov txiv roj yuav poob qis ib feem peb.
Kev poob qis ntawm kev tsim cov nplej yuav cuam tshuam rau EU cov khoom noj khoom haus, nrog rau Strategie Grains kwv yees tias yuav muaj qhov sib txawv ntawm 100,000 tonnes thiab 200,000 tonnes hauv xyoo 2022.
Yog li ntawd, kev kwv yees zaub mov hauv Tebchaws Europe twb kwv yees lawm tias tus nqi zaub mov hauv EU yuav txuas ntxiv nce siab rau lub caij nplooj zeeg thiab lub caij ntuj no xyoo 2022.
Tsis tas li ntawd xwb, qee qhov ntawm Tebchaws Meskas Midwest, lub tebchaws tsim pob kws loj tshaj plaws hauv ntiaj teb, kuj raug kev txom nyem los ntawm huab cua kub thiab qhuav, ua rau muaj kev txhawj xeeb txog nws cov kev txiav tawm.
Kev tsim cov nplej thoob ntiaj teb kuj tseem yuav poob qis xyoo no, nrog rau kev tsim cov nplej yuav poob qis 0.8 feem pua mus rau 738.4 lab tons thiab kev tsim cov pob kws poob qis 3.6 feem pua mus rau 1.13 billion tonnes, raws li Strategie Grains.
Cov lus ceeb toom tshiab kawg: qhov av qhuav tshaj plaws hauv 500 xyoo
Qhov txhawj xeeb tshaj yog, qhov kev kub ntxhov hauv Tebchaws Europe yuav txuas ntxiv mus, tsis txawm tias tsis lees paub qhov ua tau ntawm kev puas tsuaj ntxiv.
Raws li cov ntaub ntawv tshiab kawg los ntawm European Drought Observatory, 47 feem pua ntawm thaj av EU tam sim no nyob rau hauv qab kev ceeb toom txog kev qhuav, thaum 17 feem pua twb nyob rau theem siab dua. Zuag qhia tag nrho, ntau dua 60% ntawm thaj av EU nyob rau hauv kev kub ntxhov los ntawm kev qhuav.
Teb chaws Europe tej zaum yuav raug kev kub ntxhov phem tshaj plaws hauv kwv yees li 500 xyoo, raws li Andrea, tus kws tshawb fawb uas sau cov ntaub ntawv rau European Drought Observatory tau ceeb toom, Sky News tau tshaj tawm.
Andrea tau taw qhia tias qhov kev kub ntxhov hauv Tebchaws Europe xyoo 2018 hnyav heev, thiab tsawg kawg tsis muaj kev kub ntxhov zoo sib xws hauv 500 xyoo dhau los, uas hauv nws qhov kev paub dhau los yuav hnyav dua li xyoo 2018.
Hauv ntau lub teb chaws, qhov av qhuav hauv Spain yog qhov hnyav heev. Spain lub peev xwm ntawm cov pas dej tau txuas ntxiv poob qis txij li lub Yim Hli, tsuas yog tshuav 40 feem pua ntawm nws lub peev xwm, 20 feem pua qis dua qhov nruab nrab lub peev xwm rau tib lub sijhawm hauv kaum xyoo dhau los.
Ltalis kuj yog ib lub tebchaws uas raug kev kub ntxhov hnyav tshaj plaws, nrog rau tus dej loj tshaj plaws, tus dej Po, uas tau poob qis tshaj plaws hauv 70 xyoo. Tsoomfwv tau tshaj tawm qhov xwm txheej ceev hauv thaj av Po River, uas suav txog ntau dua ib feem peb ntawm Ltalis cov khoom ua liaj ua teb.
Fabkis teb raug kev kub ntxhov loj tshaj plaws hauv keeb kwm, cuam tshuam loj heev rau dej haus, kev ywg dej rau kev ua liaj ua teb thiab kev muab hluav taws xob, thiab dej hauv ntau dua 100 lub nroog thiab cov zos. Cov neeg ua liaj ua teb hauv zos tau ceeb toom tias cov khoom siv mis nyuj hauv khw yuav raug cuam tshuam rau lub caij ntuj no yog tias kev kub ntxhov tseem txuas ntxiv mus.
Qhov kev kub ntxhov tsis tshua muaj no ua rau muaj ntau yam tsis zoo rau kev lag luam hauv Tebchaws Europe. Tus thawj coj ntawm European Space Agency tau ceeb toom tias yog tsis saib xyuas kev hloov pauv huab cua, Tebchaws Europe yuav poob kaum txhiab lab daus las hauv lub xyoo pua no, lossis ntau dua li cov teebmeem tsis zoo ntawm kev kub ntxhov zog.
Cov chij liab ntawm Arctic
Tej zaum qhov kev pheej hmoo loj tshaj plaws rau qhov kub thiab txias heev hauv Tebchaws Europe yog tias qhov nrawm ntawm kev yaj ntawm Arctic glaciers tab tom nrawm dua.
Lub Washington Post tab tom sov sai dua li ntau tus kws tshawb fawb tau xav tseg, hais txog kev tshawb fawb tshiab uas tau luam tawm hauv phau ntawv xov xwm Nature Communications-The Earth and the Environment (phau ntawv xov xwm Nature Communications Earth and Environment), raws li CCTV Xov Xwm.
Cov kev tshawb fawb qhia tau hais tias Arctic yog ib qho ntawm cov cheeb tsam uas ua rau lub ntiaj teb sov tshaj plaws, nrog rau Arctic Svalbard Islands ntsib lub hli rau hli kub tshaj plaws hauv cov ntaub ntawv. Muaj ib lub sijhawm, qhov kub thiab txias hauv Arctic Circle tau nce mus txog 32.5 degrees Celsius thaum Lub Xya Hli.
Nyias muaj nyias, txoj kev tshawb fawb tau tshuaj xyuas qhov kub thiab txias hauv Arctic Circle txij xyoo 1979 txog 2021 thiab pom tias qhov sov ntawm Eurasian qhov chaw ntawm Arctic Ocean, tshwj xeeb tshaj yog hauv Barents Hiav Txwv, yog xya npaug ntawm qhov nruab nrab thoob ntiaj teb.
Qhov kub heev hauv Arctic ib zaug ua rau lub ntiaj teb ntxhov siab, thiab lub ncauj lus ntawm "Lub Arctic twb tuaj yeem hnav tes tsho luv luv" tau dhau los ua ib qho ncauj lus kub.
Cov ntaub ntawv tshiab qhia tau tias qhov nruab nrab txhua xyoo kub hauv thaj av Barents Hiav Txwv tau nce 2.7 degrees Celsius txhua 10 xyoo dhau los 20 txog 40 xyoo dhau los, ua rau Hiav Txwv Barents thiab nws cov kob yog qhov chaw sov tshaj plaws hauv ntiaj teb.
Qhov kub thiab txias siab heev no ua rau cov dej khov Arctic yaj sai dua. Thaum kawg ntawm lub Xya Hli, 40 billion tons ntawm cov dej khov hauv Arctic Svalbard tau yaj mus rau hauv dej hiav txwv, raws li cov ntaub ntawv tshawb fawb tshiab los ntawm phau ntawv xov xwm Nature Communications-Earth and the Environment.
Tsis tas li ntawd xwb, daim dej khov uas npog Greenland, lub kob loj tshaj plaws hauv ntiaj teb, tab tom yaj sai dua. Cov kws tshawb fawb ntawm University of Texas tau hais tias tag nrho cov dej khov Greenland yaj tag nrho yog qhov xav tsis thoob vim qhov kub nce siab, txawm tias cov dej khov yaj nyob ntawm lawv xub ntiag kuj hnov tias muaj dej khov yaj.
Raws li cov ntaub ntawv raug cai, feem ntau ntawm Greenland nyob hauv Arctic Circle, thiab kwv yees li 80 feem pua ntawm cov kob yog npog los ntawm cov dej khov, qhov thib ob loj tshaj plaws hauv ntiaj teb, npog yuav luag 1.8 lab square kilometers, tom qab Antarctic ice sheet, thiab qhov kub nruab nrab txhua xyoo yog qis dua 0 degrees Celsius.
Txij lub Rau Hli mus txog rau thaum pib lub Cuaj Hli, nws yog lub caij ablation ntawm Greenland ice sheet. Tab sis txij li Lub Xya Hli 2022, qhov kub thiab txias siab tsis zoo hauv Tebchaws Europe tau ua rau cov dej khov hauv Greenland yaj sai dua. Cov kws tshawb fawb tau ceeb toom tias yog tias cov teebmeem tsis zoo ntawm kev hloov pauv huab cua, xws li qhov kub thiab txias siab, txuas ntxiv mus, Greenland ice sheet yuav yaj ntxiv, thiab dej hiav txwv thoob ntiaj teb tuaj yeem nce 7.5 meters, cov kws tshawb fawb tau hais.
Qhov teeb meem loj tshaj plaws hauv Asmeskas Sab Hnub Poob
Thoob plaws dej hiav txwv, Tebchaws Meskas kuj tab tom ntsib teeb meem qhuav heev.
Kwv yees li 6 feem pua ntawm sab hnub poob ntawm Tebchaws Meskas qhuav heev, raws li txhais los ntawm kev poob ntau ntawm cov qoob loo hauv zos thiab cov nyom, raws li US Drought Monitor (USDM), thiab tag nrho cov dej tsis txaus.
Ntxiv rau qhov ntawd, 23 feem pua ntawm sab hnub poob ntawm Tebchaws Meskas muaj kev kub ntxhov heev, qeb duas qis dua "kev kub ntxhov heev"; 26 feem pua muaj kev kub ntxhov heev, kev tsis txaus dej yuav tshwm sim tas li, thiab tsoomfwv hauv nroog yuav tsim cov kev txwv dej.
Qhov ntawd txhais tau tias 55 feem pua ntawm sab hnub poob ntawm Tebchaws Meskas tam sim no dhau ntawm qhov kev kub ntxhov loj heev. Ntau lub chaw xov xwm hauv Tebchaws Meskas tau hais tias qhov no yog qhov kev kub ntxhov phem tshaj plaws hauv kev tsim tsa ntau tshaj 200 xyoo.
Tshwj xeeb, lub xeev uas muaj neeg coob tshaj plaws, —— California, muaj 100 feem pua ntawm nws thaj chaw tau tshaj tawm tias muaj kev kub ntxhov, nrog rau 97.5 feem pua ntawm kev kub ntxhov hnyav lossis siab dua.
Cov neeg nyob hauv California yav qab teb tau raug thov kom txo kev siv dej los ntawm 20 feem pua, thaum Tus Thawj Kav Tebchaws Gavin Newsom tau hais rau lub rooj sib tham thaum kawg Lub Xya Hli tias xav tau ntau txoj haujlwm ntxiv rau cov peev txheej dej, thiab yuav ua li cas nkag mus, khaws cia thiab faib nws yuav xav kom lub xeev ua haujlwm ua ke.
Ntxiv rau qhov ntawd, Lake Mead, lub pas dej loj tshaj plaws hauv Tebchaws Meskas, kuj tau tshaj tawm lub tswb ceeb toom. Dej Lake Mead tau poob qis heev hauv 20 xyoo dhau los, raws li cov duab satellite uas NASA tso tawm thaum kawg Lub Xya Hli. Txij li Lub Xya Hli 18, Lake Midd tsuas yog 27% ntawm nws qib dej siab tshaj plaws, qib qis tshaj plaws txij li xyoo 1937.
