Recent evidence has shows that our planet has plummeted into periods of intense cold time and time again in the past. The question is: When will we nest freeze over?
Naked Science reveals how massive volcanic eruptions can cause global temperatures to drop for up to twoyears. The small changes in climate volcanoes cause often start domino effect. Huge Big Freezes are caused by changes in our oceans. Our oceans constantly flow in a circuit called the Great Ocean Conveyor. This transports cold water to the equator preventing it from constantly heating and transports warm water to the poles, preventing them from plummeting off the scale into a Big Freeze. The latest Evidence shows that this shut-down might already be underway. 最近有证据表明:过去曾出现的周期性寒流一次又一次的强烈冲击着我们的地球。。。。。。。问题是:什么时候人类将会迎来下一次的大冰冻呢?
科学透视节目揭示了近几年来大规模的火山爆发可能导致了全球的气温下降。然而气候的微小变化着成了骨牌效应 - 火山的爆发,又进一步使气温下降。大冰冻会使我们的海洋发生巨大的变化,海水经常周期性地流动,冷流到了赤道就被暖流加热,从而阻止它结冰。但是最近的证据表明, 大冰冻仍会有出现的可能。
