???英国广播公司（BBC）在2007年出版的科学纪录片-英语旁白Science Documentary published by BBC in 2007 - English narration

您是否知道气候变化现在如此严重，以至于科学家们正在考虑采用大型遮阳篷以保持凉爽？还是促进海洋中的浮游生物种群吸收二氧化碳？全球变暖正在以前所未有的速度改变世界。冻的苔原正在融化，巨大的冰盖正在破裂，海平面在上升，天气模式也在变化。但这并不是所有的厄运和忧郁。面对迫在眉睫的灾难，一些世界上最杰出的科学家正在研究此案。其他计划包括用多余的云层保护地球免受阳光照射，将“人造树”存储在地下以及使用重型火炮将硫磺射入平流层。我们需要快速拯救地球。人类的创造力可能会带来挑战。全球都在感受到气候变化，如果全球变暖继续加剧，后果将是灾难性的。电影中提出的前三个提议的想法着眼于降低太阳的能量-从而冷却地球。来自亚利桑那州的罗杰·安吉尔（Roger Angel）教授（世界上最大的望远镜的设计者）建议在太空中放置巨大的玻璃遮阳篷。Angel教授的遮阳帘会将一小部分的太阳光偏转回太空。荷兰人Paul Crutzen教授发现了造成臭氧层空洞的原因，因此获得了诺贝尔化学奖。他的计划是将数百吨载有硫磺的火箭发射到平流层，在地球周围形成巨大但非常稀薄的硫磺防晒霜。英国大气物理学家约翰·拉瑟姆教授和工程师史蒂芬·索特尔?设计了一批遥控游艇。这些将海水中的细小颗粒泵入云层，增加云层的厚度并反射太阳光线。计划中的另外两个人希望解决二氧化碳过多的问题-原因全球变暖。悉尼工程师伊恩·琼斯（Ian Jones）教授建议给浮游生物喂加仑的肥料。这将使浮游生物生长并吸收空气中的二氧化碳。纽约的克劳斯·拉克纳（Klaus Lackner）教授设计了一种二氧化碳捕获机，他的计划是在全球范围内找到更多的二氧化碳捕获机。他们会吸收二氧化碳，将其转化为粉末，然后将其埋在废弃的石油或天然气田中的海底深处。大多数科学家都不愿倡导这些想法，所有人都认为我们应该减少对矿物燃料的使用，从而为我们的房屋供暖和驾驶汽车。尽管这些想法可能产生未知的副作用，但一些科学家认为我们可能很快就不得不将这些激进而有争议的计划付诸行动。Did you know climate change is now so serious that scientists are considering putting a big sunshade in place to keep us cool? Or boosting the ocean's plankton populations to absorb carbon dioxide? The world is being transformed by global warming faster than anyone anticipated. Frozen tundra is melting, giant icecaps are breaking, sea levels are rising and weather patterns are changing. But it's not all doom and gloom; some of the world's most eminent scientists are on the case, in the face of imminent catastrophe. Other plans include shielding the earth from the sun with extra clouds, storing 'artificial trees' underground and using heavy artillery to fire sulphur into the stratosphere. We need to save the planet, fast. And human ingenuity may rise to the challenge.Climate change is being felt the world over and if global warming continues to increase the effects could be catastrophic. The first three proposed ideas featured in the film, look at reducing the power of the sun - thereby cooling the planet. Professor Roger Angel from Arizona - the designer of the world's largest telescope - is proposing to put a giant glass sunshade in space. Professor Angel's sunshade will deflect a small percentage of the sun's rays back into space.Dutch Professor Paul Crutzen won the Nobel Prize for chemistry when he discovered the causes of the hole in the ozone layer. His plan is to fire hundreds of rockets loaded with tons of sulphur into the stratosphere creating a vast, but very thin sunscreen of sulphur around the earth.British atmospheric physicist Professor John Latham and engineer Stephen Salter, have designed a fleet of remote-controlled yachts. These will pump fine particles of sea water into the clouds, increasing the thickness of the clouds and reflecting the suns rays.</br>Carbon dioxide debateThe other two men in the programme want to tackle the problem of excess carbon dioxide - the cause of global warming. Sydney engineer Professor Ian Jones proposes to feed plankton with gallons of fertiliser. This will make the plankton grow and absorb carbon dioxide from the air. And New York-based Professor Klaus Lackner has designed a carbon dioxide capturing machine and his plan is to locate more of them across the globe. They would suck in carbon dioxide, turn it into a powder and he would bury it deep under the ocean in disused oil or gas fields.Most of the scientists are reluctant advocates of these ideas, and all believe we should be cutting down on our use of fossil fuels to heat our homes and drive our cars. But is time running out for planet earth?Although these ideas might have unknown side effects, some scientists believe we may soon have no choice but to put these radical and controversial plans into action.
