Earth: The Power of the Planet
地球的力量
伊恩·斯图尔特向我们介绍地球形成的故事。在地球形成的45亿年中，是什么力量塑造了地球如今的模样。通过这一系列节目我们将了解到形成地球的诸多因素，火山、大气、冰雪、海洋等等。 四种伟大的能量——火山、大气层、冰川和海洋联合起来塑造了我们这个伟大的星球。不可思议地将我们的地球变成一个独一无二的星球，并为生命创造了完美的生存条件。这些力量塑造了这个星球，并一直在保护着它,然而有的时候也会给它带来灾难。地球从光秃秃的岩石变成我们今天熟悉的世界，一共花费了45亿年，那是充满了灾难和重生的不可思议的旅程。这个稀少又壮丽的星球一直面临着巨大的挑战，包括来自我们人类的。在各种力量的作用下，地球会幸存下去吗?
Volcanoes have a fearsome reputation. In reality, they are the most important force in the creation of the planet as we know it today. Iain abseils into a lava lake and cave dives in a cenote to show how the heat that fuels volcanoes also drives some of the most fundamental processes on the planet.
Iain travels into the stratosphere in a Cold War fighter, gets his eyebrows singed in Siberia and discovers why Argentina is one of the stormiest places on Earth. All to show why our atmosphere is unique and utterly crucial for life.
Ice may be nothing more than frozen water but, as Iain explains, it holds extraordinary power. Descending 150m down a frozen waterfall, he sees a glacier in action from below and discovers why the huge Jacobshaven glacier is retreating, he shows how it shaped our past and may now threaten our future.
Travelling from Hawaii to the Amazon and Ethiopia and then on to the Mediterranean, Iain tells the story of the oceans – fierce waves, huge tidal bores, global currents and the future dangers of global warming.
Iain looks at the big picture of Earth's place in space. It's taken four and a half billions years and several great catastrophes to turn it from a barren rock to the unique planet we know today.
