Nuclear Winter

推薦 0 收藏 0 轉貼0 訂閱站台


六千五百萬年前一場前所未有的大火,燒毀了森林,因為隕石撞擊地球,它摧毀了一個世界,卻為新的世界開啟了一條路。

當時的煙與撞擊產生的飛塵充滿了地球整個天空,連陽光都透進不來,儘管當時究竟有多黑暗仍沒有定論,但某些模擬中結果認為,當時地表就像是無光的洞穴般的黑暗,無論如何,行光合作用的植物死去,食物鏈瓦解,即使野火未及的海洋也是如此,這個階段被聯想到”核冬”(蘇聯跟美國的冷戰時期)有些模擬推測,核冬是在核交換後會隨之而來的一段寒冷時期,這些煙塵要花數個月的時間才能洗淨,它們可能像藍雨一樣的落下(就像火山爆發噴發後所見富含火山灰的藍色雨滴一般)。

Since 65 million an asteroid impact Earth . everything is burned.It destroyed one world amd made a new one.

Soot and impacted-generated dust choked the sky over the entire planet,making it impermeable to sunlight.Some calculations suggest that the surface was as dark as a lightless cave,although the percise amount of darkening remains uncertain.In any event,photosynthetic plants died and food chains collapsed,even in areas untrouched by wildfires,such as the sea.This phase has been likened to ”unclear winter”,a cold spell that some modelers have suggested may follow a nuclear exchange.The dirt took months to wash out,probably falling as blue rain similar to the blue ash-rich rain seen after modern volcanic eruptions.
