Mu moyo wake wonse, munthu mosagwiritsa ntchito maubwino achilengedwe, zomwe zidapangitsa kuti pakhale zovuta zambiri zachilengedwe m'nthawi yathu ino. Kupewa ngozi yapadziko lonse ili m'manja mwa munthu. Tsogolo la Dziko Lapansi limadalira pa ife tokha.

Mfundo zodziwika

Asayansi ambiri amaganiza kuti vuto lakutentha kwadziko labwera chifukwa cha kuchuluka kwa mpweya wowonjezera kutentha mkati mwa dziko lapansi. Amalepheretsa kutentha komwe kukuunjikira kudutsa. Mpweya uwu umapanga dome losazolowereka, lomwe limabweretsa kuwonjezeka kwa kutentha, komwe kumapangitsa kusintha kwakanthawi kwamadzi oundana. Izi zimakhudza nyengo yonse padziko lapansi.

Mvula yayikulu kwambiri ili ku Antarctica. Magulu akulu a ayezi kumtunda amathandizira kutsika kwake, ndipo kusungunuka mwachangu kumathandizira kuchepa kwa madera onse azilumbazi. Madzi oundana a Arctic amakhala ndi kutalika kwa mamiliyoni 14 miliyoni. Km.

Chifukwa chachikulu cha kutentha

Atachita kafukufuku wambiri, asayansi adazindikira kuti chifukwa chachikulu cha tsokali lomwe likuyembekezeka ndi zochitika za anthu:

  • kudula mitengo mwachisawawa;
  • kuipitsa nthaka, madzi ndi mpweya;
  • Kukula kwa mabizinesi opanga.

Madzi oundana akusungunuka kulikonse. Kwazaka makumi asanu zapitazi, kutentha kwa mpweya kwakula ndi madigiri 2.5.

Pali lingaliro pakati pa asayansi kuti njira yothetsera kutentha kwa dziko ndiyotsogola, ndipo idayambitsidwa kalekale ndipo kutenga nawo gawo anthu kumakhala kochepa. Izi ndizokopa kuchokera kunja komwe kumalumikizidwa ndi astrophysics. Akatswiri mdera lino amawona chifukwa chakusintha kwanyengo momwe mapulaneti ndi zinthu zakuthambo zimasinthira.

Zotsatira zotheka

Pali malingaliro anayi omveka

  1. Nyanja zidzakwera ndi mamita 60, zomwe zithandizira kusintha kwa magombe ndikusintha kwambiri madzi osefukira.
  2. Nyengo padziko lapansi idzasintha chifukwa cha kusuntha kwa mafunde am'nyanja, ndizovuta kwambiri kulosera zotsatira zakusinthaku momveka bwino.
  3. Kusungunuka kwa madzi oundana kudzatsogolera ku miliri, yomwe iphatikizidwa ndi anthu ambiri omwe akhudzidwa.
  4. Masoka achilengedwe adzawonjezeka, kumabweretsa njala, chilala, ndi kusowa kwa madzi abwino. Chiwerengero cha anthu chikuyenera kusamukira kumtunda.

Kale, munthu akukumana ndi mavutowa. Madera ambiri amavutika ndi madzi osefukira, ma tsunami akuluakulu, zivomezi, kusintha kwa nyengo. Mpaka pano, asayansi padziko lonse lapansi akuyesetsa kuthetsa vuto losungunuka kwa madzi oundana ku Greenland ndi Antarctica. Zimayimira madzi abwino kwambiri, omwe, chifukwa cha kutentha, amasungunuka ndikupita kunyanja.

Ndipo m'nyanja, chifukwa chamchere, kuchuluka kwa nsomba, zomwe zimagwiritsidwa ntchito posodza anthu, zikuchepa.

Kusungunuka Greenland

Zothetsera

Akatswiri apanga njira zingapo zomwe zithandizira kuthana ndi mavuto azachilengedwe:

  • kukhazikitsa chitetezo chapadera potizungulira dziko lapansi pogwiritsa ntchito magalasi ndi zotsekera zoyenera pamapiri oundana;
  • zimaswana mbewu ndi kuswana. Zidzakhala ndi cholinga chofuna kuyamwa kaboni dayokisaidi;
  • gwiritsani ntchito njira zina zopezera mphamvu: kukhazikitsa mapanelo amagetsi ozungulira dzuwa, makina oyendera mphepo, makina opangira magetsi;
  • kusamutsa magalimoto kumalo ena amphamvu;
  • Limbikitsani kuyang'anira mafakitale kuti akhumudwitse osadziwika kuti atulutsa mpweya.

Njira zopewera ngozi yapadziko lonse ziyenera kuchitidwa kulikonse komanso m'magulu onse aboma. Iyi ndiyo njira yokhayo yothetsera masoka omwe akubwerawa ndikuchepetsa ziwopsezo.
