Isithombe - NASA
Njalo eminyakeni eyishumi nanye noma kunjalo, amabala enkanyezi yethu ayaphela. Lokhu yilokho okwaziwa njengobuncane belanga, futhi njengamanje sikhuluma eyodwa. Phakathi kweminyaka engu-2019-2020 kulindeleke ukuthi bafinyelele endaweni yabo ephansi, kepha Uyowuthinta kanjani umhlaba?
Iqiniso ukuthi namanje akwaziwa ngokuqinisekile, kepha singathola umbono wokuthi kuzokwenzekani sibonga iNASA.
ILanga lihamba ngemijikelezo yeminyaka eyishumi nanye noma ngaphezulu, phakathi kokukhona okuphezulu, okungukuthi, lapho linamabala amaningi elanga, kanye nobuncane. Kuyaziwa ukuthi lapho kunamabala amaningi, kuyashisa, futhi ngokuphambene nalokho, lapho kuncane okukhona, kuzoba kubanda. Kungani? Kulungile, imisebe efinyelela kithi ivela eLangeni iyahlukahluka ngo-0,1% phakathi kwesilinganiselo selanga nobuncane. Kungabonakala kukuncane kakhulu, akukho lutho, kepha khumbula lokho inkosi yezinkanyezi iyakwazi ukukhipha inani elikhulu lamandla.
Phakathi kuka-1645 no-1715 yayinezindawo ezimbalwa kakhulu, futhi izinga lokushisa lomhlaba beliphansi ngo-1ºC evamile. Kwakuyisikhathi esaziwa njenge- "Maunder Minimum", yize abanye beyazi kangcono i- "Little Ice Age. Phakathi naleso sikhathi, bobabili iYurophu neNyakatho Melika babhekana nobusika obunzima kakhulu, nezinguzunga zeqhwa ezazithola indawo.
Ubuncane beMaunder
Kodwa ingabe yilokho okulindele thina maduze? Kungenzeka, kepha iqiniso ukuthi kunomehluko obalulekile: manje umkhathi ugcwele isikhutha, okusho ukuthi singakususa ukupholisa kancane. Futhi, nganoma iyiphi indlela, ngeke sikwazi ukwenza okuningi ekulweni neziphepho ze-geomagnetic ezizofika kithi. Mayelana nalokhu, uDean Pesnell we-NASA's Goddard Space Flight Center uthe isimemezelo lokho »ngesikhathi sobuncane belanga, amandla kazibuthe elanga enza buthakathaka futhi anikeze ukuvikelwa okuncane emisebeni ye-cosmic. Lokhu kungaba yingozi enkulu kosomkhathi abahamba emkhathini. '
