Makore gumi nerimwe ega kana zvakadaro, iwo mavara pane yedu nyeredzi anopera. Izvi ndizvo zvinozivikanwa sekushomeka kwezuva, uye isu tiri parizvino kutaura kune imwe. Pakati pemakore 2019-2020 ivo vanotarisirwa kusvika kune yavo yepazasi poindi, asi Ichakanganisa sei nyika?
Chokwadi ndechekuti hachisati chazivikanwa zvechokwadi, asi isu tinogona kuwana pfungwa yezvichaitika nekutenda kuNASA.
Zuva rinoenderera nematanho emakore gumi nerimwe kana zvakadaro, pakati peiyo pane yakanyanya, ndiko kuti, kana iine akawanda maspots ezuva, uye hushoma. Iyo inozivikanwa kuti iyo yakawanda mavara iyo yainayo, iyo inopisa kwazvo, uye pane zvinopesana, izvo zvishoma zviripo, iyo inotonhora ichave iri. Sei? Zvakanaka, radiation iyo inotisvikira kubva kuZuva haina kusiyana 0,1% pakati pehurefu hwezuva uye hushoma. Inogona kutaridzika sediki kwazvo, pasina kana chinhu, asi inofanirwa kutakurwa mupfungwa kuti nyeredzi mambo inokwanisa kuburitsa yakawanda simba.
Pakati pemakore 1645 na1715 yaive nemavara mashoma, uye tembiricha yepasi yakanga yakadzika ne1ºC zvakajairwa. Yakanga iri nguva inonzi "Maunder Minimum", kunyange vamwe vachiziva zviri nani kune "Little Ice Age." Munguva iyoyo, zvese zviri zviviri Europe neNorth America vakasangana nechando chakanyanya, nemagirazi echando aive achiwana nzvimbo.
Maunder mashoma
Asi ndizvo izvo zvakatimirira munguva pfupi here? Zvinogona kudaro, asi chokwadi ndechekuti pane musiyano wakakosha: iye zvino mhepo yakatakurirwa nekabhoni dhayokisaidhi, zvinoreva kuti isu tinogona kubvisa kutonhora zvishoma. Uye, chero nenzira, isu hatizokwanise kuita zvakawanda kurwisa geomagnetic madutu achauya kwatiri. Panyaya iyi, Dean Pesnell weNASA's Goddard Space Flight Center akadaro mune a kusunungurwa iyo »panguva yekushomeka kwezuva, iro raZuva remagineti rinopera simba uye rinopa kudzivirirwa kushoma kubva kumagetsi e cosmic. Izvi zvinogona kutyisidzira zvikuru vanoongorora muchadenga vanofamba nepakati. '
