太陽(yáng)已經(jīng)進(jìn)入“禁閉”期，這可能會(huì)導(dǎo)致冰凍天氣、饑荒

Our sun has gone into lockdown, which could cause freezing weather, earthquakes and famine, scientists say.

科學(xué)家說(shuō)，我們的太陽(yáng)已經(jīng)進(jìn)入禁閉狀態(tài)，這可能導(dǎo)致冰凍天氣、地震和饑荒。

The sun is currently in a period of “solar minimum,” meaning activity on its surface has fallen dramatically.

太陽(yáng)目前正處于“太陽(yáng)活動(dòng)極小期”，這意味著其表面的活動(dòng)已經(jīng)急劇下降。

Experts believe we are about to enter the deepest period of sunshine “recession” ever recorded as sunspots have virtually disappeared.

專家認(rèn)為，隨著太陽(yáng)黑子幾乎消失，我們即將進(jìn)入有史以來(lái)最深的日照“衰退”時(shí)期。

Astronomer Dr. Tony Phillips said: “Solar Minimum is underway and it’s a deep one.”

天文學(xué)家托尼菲利普斯博士說(shuō)：“太陽(yáng)活動(dòng)極小期正在進(jìn)行，這是很深的一次。”

“Sunspot counts suggest it is one of the deepest of the past century. The sun’s magnetic field has become weak, allowing extra cosmic rays into the solar system.”

太陽(yáng)黑子的數(shù)量表明這是上個(gè)世紀(jì)最深的一次。太陽(yáng)的磁場(chǎng)變得很弱，允許額外的宇宙射線進(jìn)入太陽(yáng)系。”

“Excess cosmic rays pose a health hazard to astronauts and polar air travelers, affect the electro-chemistry of Earth’s upper atmosphere and may help trigger lightning.”

“過(guò)量的宇宙射線對(duì)宇航員和極地旅行者的健康構(gòu)成危害，影響地球上層大氣的電化學(xué)，并可能引發(fā)閃電。”

NASA scientists fear it could be a repeat of the Dalton Minimum, which happened between 1790 and 1830 — leading to periods of brutal cold, crop loss, famine and powerful volcanic eruptions.

美國(guó)國(guó)家航空航天局的科學(xué)家們擔(dān)心，這可能是道爾頓極小期的重演。道爾頓極小期發(fā)生在1790年到1830年之間，導(dǎo)致了嚴(yán)寒、作物歉收、饑荒和火山爆發(fā)。

Temperatures plummeted by up to 2 degrees Celsius (3.6 degrees Fahrenheit) over 20 years, devastating the world’s food production.

20年內(nèi)，氣溫驟降了2攝氏度(3.6華氏度)，破壞了世界糧食生產(chǎn)。

On April 10, 1815, the second-largest volcanic eruption in 2,000 years happened at Mount Tambora in Indonesia, killing at least 71,000 people.

1815年4月10日，印尼坦博拉山發(fā)生2000年來(lái)第二大火山噴發(fā)，造成至少7.1萬(wàn)人死亡。

It also led to the so-called Year Without a Summer in 1816 — also nicknamed “eighteen hundred and froze to death” — when there was snow in July.

這也導(dǎo)致了所謂的1816年的無(wú)夏之年——也被稱為“凍死人的1800”——當(dāng)年7月飛雪。

So far this year, the sun has been “blank” with no sunspots 76 percent of the time, a rate surpassed only once before in the Space Age — last year, when it was 77 percent blank.

今年以來(lái)，太陽(yáng)一直是“空白”的，76%的時(shí)間沒(méi)有太陽(yáng)黑子，這一比例在太空時(shí)代只超過(guò)過(guò)一次——去年，77%。
