kutentha kwambiri kumayambitsa imfa

Kutentha kwadziko ndi kusintha kwa nyengo zikuchitika makamaka chifukwa cha kuchuluka kwa mpweya wowonjezera kutentha womwe anthu amatulutsa kuyambira pomwe mafakitale asintha. Akuyerekeza kuti 74% ya anthu padziko lapansi adzakumana ndi mafunde otentha pofika chaka cha 2100.

Ndiye chifukwa chake, tikapitiliza chonchi, mwayi woti tidzalimbane ndi mafunde akuchepa udzakhala wocheperako.

Mafunde otentha amapha anthu masauzande ambiri padziko lonse lapansi chaka chilichonse. Vuto lalikulu lomwe limalumikizidwa ndi mafunde otentha ndi chilala. Kutentha komwe timakhala nako kutentha kwa dzuwa, madzi amasanduka nthunzi ndipo madzi amchere amakhala ochepa. Chifukwa chake mphamvu yamafunde otentha imakula kwambiri pakakhala chilala.

Ngati mpweya wowonjezera kutentha ukupitilira pamlingo uwu, kutentha kwapadziko lonse lapansi kudzapitilizabe kukwera ndipo sipadzakhala Mgwirizano waku Paris womwe ungaletse izi.

Kafukufukuyu wachita kafukufuku paimfa zonse zomwe zadzetsa kutentha kwamphamvu kuyambira 1980. Oposa milandu 1.900 apezeka kumadera osiyanasiyana padziko lapansi komwe kutentha kwadzetsa imfa. Pakhala pali mafunde otentha 783 ndipo apeza kutentha ndi chinyezi momwe, kuchokera pamenepo, zovuta paumoyo ndizowopsa. Dera la dziko lapansi komwe nyengo ipitirire malowo kwa masiku 20 kapena kupitilira apo pachaka yawonjezeka m'zaka zaposachedwa ndipo asayansi akukhulupirira kuti ipitilizabe kukula ngakhale mpweya wowonjezera kutentha umachepetsedwa.

Zitsanzo zoperekedwa ndi akatswiri ndi monga kutentha komwe kudagunda ku Europe mu 2003 ndikupha anthu pafupifupi 70.000, womwe udakhudza Moscow (Russia) ku 2010 ndipo udapha anthu 10.000 kapena Chicago ku 1995 , yomwe inapha anthu 700.
