2004年底,除了地震海啸,世界部分地区出现了罕见大雪。影片《后天》描绘的那种冰冷世界会不会到来?科学家正在从历史中寻找线索 近日,美国冰河学家朗尼·汤普森撰文国际先驱导报声称,他可能找到了一些线索能够证明:在5200年前,地球的气候曾经发生过剧烈变化。如果他是正确的,研究结果很可能对今天的人们是一个重要的暗示。 汤普森花费了整个职业生涯,跋涉于世界许多角落,去寻找偏僻的冰原,从中钻取冰核。那些冰核里记载了全球古代的气候变化。
At the end of 2004, except for the earthquake and tsunami, rare heavy snowfall occurred in some parts of the world. Scientists are looking for clues in history Recently, the American glaciologist Lonnie Thompson wrote that the International Herald Tribune may have found some clues to prove that in the 5200’s Before the Earth’s climate had undergone dramatic changes. If he is right, the findings are likely to be an important hint to people today. Thompson spent his entire career trekking around many parts of the world looking for remote ice sheets and drilling ice cores. Those ice cores record the ancient climate change in the world.
