Lub ntiaj teb magnetic teb tiv thaiv peb ntawm cosmic hluav taws xob. Peb cov ntaub thaiv npog tau raug tso tawm thiab qhov no yog xov xwm phem heev rau txhua tus neeg nyob hauv peb lub ntiaj teb thiab qhov no tseem tuaj yeem ua rau lwm qhov kev ploj tuag.

Txij li xyoo 1850, lub ntiaj teb cov hlau nplaum tsis muaj zog. Thaum lub sij hawm tig ntawm lub xyoo txhiab, nws pib poob exponentially, los ntawm ntau tshaj 10% nyob rau hauv ib xyoo caum - lub caij nplooj zeeg no yog heev thiab ceeb …

David Mauriello ntawm ORP thiab MRN hais tias "Thaum thaj chaw sib nqus tsis muaj zog, cov ncej hloov pauv," hais tias 100 xyoo dhau los, ob sab qaum teb thiab sab qab teb tus ncej tau nrawm nrawm rau ntawm txoj kab nruab nrab thiab lawv qhov sib xyaw nce ntxiv, ceeb toom Mauriello.

Lub S Ncej tam sim no nyob tom qab Antarctic sab av loj thiab tab tom mus ncaj rau Indonesia, thiab N Ncej tab tom hla lub Arctic Circle mus rau Siberia, nws tseem tab tom mus rau Indonesia - qhov twg cov ncej zoo li yuav ntsib ntau xyoo tom ntej no, tej zaum. nyob ib ncig ntawm 2050.

Qhov "kev sib ntsib" no yuav ua rau ib qho ntawm ob txoj kev xaiv tau:

1) yuav muaj kev hloov pauv tag nrho (aka "coup", qhov twg cov ncej hlau nplaum hloov)

los yog

2) "thov rov qab" yuav tshwm sim thiab cov ncej yuav sai sai rov qab mus rau lawv cov ntsiab lus thawj zaug (hauv lwm lo lus, "kev mus ncig ua si").

Qhov teeb meem tseem ceeb, txawm li cas los xij, tsis yog tus ncej hloov, txawm hais tias qhov no yeej yog ib qho teeb meem, Mauriello txuas ntxiv. Tsis yog, qhov teeb meem loj tshaj plaws yog waning magnetosphere uas tshwm sim los ntawm tus ncej hloov.

"Raws li cov hlau nplaum tsis muaj zog, ntau thiab ntau dua cosmic hluav taws xob tuaj yeem nkag mus rau lub ntiaj teb," Mauriello piav qhia.

Tsis tsuas yog cosmic rays yuav nce, tab sis tag nrho cov dav spectrum ntawm hluav taws xob kuj yuav nce. Koj puas pom lub caij ntuj sov no tsuas yog sawv hauv lub hnub rau ob peb feeb xwb yog ntuj txiag teb tsaus?”

"Qhov no yog vim peb nyob rau ntawm lub hnub ci yam tsawg kawg nkaus, peb muaj qhov txo qhov sib nqus, thiab koj hnov qhov cuam tshuam ntawm cov hluav taws xob no. Thiab qhov no, hmoov tsis, yuav nce ntxiv rau koj lub neej - lossis ntev npaum li qhov kev thim rov qab / taug kev tshwm sim."

Nyob rau hauv xyoo tas los no, nws tau raug sau tseg tias sib nqus inversions thiab excursions tau ua rau qee qhov loj tshaj plaws extinctions nyob rau hauv lub ntiaj teb no, suav nrog rau thaum ntxov Dryas tshwm sim, uas wiped tawm mus txog 65% ntawm lub ntiaj teb no megafauna.

Thiab qhov no twb tshwm sim tam sim no!

Cov duab mob siab rau pom qhov tshwm sim tom qab Australia qhov phem tshaj plaws whale tsaws hauv keeb kwm. Txog niaj hnub no, kwv yees tias ze li ntawm 400 whales tau tuag.

Nws yuav zoo mus rau hauv keeb kwm raws li ib qho ntawm cov xwm txheej loj tshaj plaws hauv keeb kwm, tab sis nws yeej tsis tau muaj dua. Tsis ntev los no, muaj cov ntaub ntawv ntawm ntau lwm cov lus qhia, thiab ntxiv rau, lawv txhua tus tshwm sim thaum lub hnub ci minima.

Rov qab rau xyoo 1985, kwv yees li 450 whales tau tso tseg hauv Auckland, New Zealand. Xyoo 1996, 320 whales tau tso tseg ntawm Dunsborough, Washington.

Tsis tas li ntawd, ntau tshaj 50 tus whales stranded tau pom hauv Tasmania lub lim tiam no thawj zaug txij li xyoo 2009.

Thiab hauv 2017, 600 whales staggering tsaws ntawm New Zealand lub South Island, tua ntau dua 350.

Yog li, qhov no yog 1985, 1996, 2009, 2017, thiab tam sim no 2020 - cov no tsis yog hnub sib txawv: tag nrho cov xyoo no poob rau hauv lub hnub ci minima, "thaum lub siab tshaj plaws cosmic hluav taws xob nkag mus rau lub ntiaj teb, thiab qhov no kuj tseem yuav txo qis hauv lub hnub ci. Sib nqus teb - tsis meej pem rau tsiaj "- sau ntawv Mauriello.

Mauriello hais tias "Cov no yog cov xwm txheej uas tuaj yeem ua tau raws li kev ploj mus ib txhij ntawm magnetosphere thiab kev tawg ntawm peb lub hnub," Mauriello hais. "Cov xwm txheej no yuav mus ntxiv rau lwm xyoo lossis yog li ntawd, thiab tom qab ntawd thaum peb tsoo lub hnub ci yam tsawg kawg ntawm lub voj voog 25, peb tuaj yeem cia siab tias lawv yuav tshwm sim hauv 2031, 2032, 2033."

Mauriello xaus lus: "Qhov sib nqus deflection lossis thim rov qab yuav txuas ntxiv thaum lub hnub tseem nkag mus rau qhov qis qis - ob qhov xwm txheej no tshwm sim tib lub sijhawm, hauv kuv lub tswv yim, tsis yog qhov xwm txheej, tab sis qhov tseeb yuav ua rau lub hnub nyoog me me uas twb muaj lawm."

"Koj thiab kuv - peb txhua tus zoo li tau ntsib qhov pib ntawm kev puas tsuaj loj tom ntej ntawm lub ntiaj teb no."
