        CARL AZUZ, CNN STUDENT NEWS ANCHOR: You're watching CNN Student News! You give us 10 minutes, we'll give you today's headlines, with absolutely no commercials. I'm Carl Azuz. Let's go ahead and get started.
        AZUZ: First up, President Obama makes his case for the U.S. military's involvement in Libya. In a speech on Monday night, the president said he ordered troops to take action against Libya because of what he called the "looming humanitarian crisis" in the North African country. President Obama said that outweighed other concerns.
        U.S. PRESIDENT BARACK OBAMA: It's true that America cannot use our military wherever repression occurs. Given the costs and risks of intervention, we must always measure our interests against the need for action. But that cannot be an argument for never acting on behalf of what's right. In this particular country, Libya, at this particular moment, we were faced with the prospect of violence on a horrific scale. We had a unique ability to stop that violence.
        AZUZ: The president's been getting a lot of criticism for how he's handling this situation in Libya. You can see some of that in yesterday's show. President Obama had said previously that the U.S. goal was to remove Libyan leader Moammar Gadhafi from power. But in the speech he made on Monday night, the president said the U.S. shouldn't do that directly. And a leading Republican senator says that shift is a serious mistake.
        SEN. JOHN MCCAIN, (R) ARIZONA: If Gadhafi remains in power, it'll be a stalemate. We saw a stalemate before after Operation Desert Storm. We saw a no-fly zone and sanctions that lasted for 10 years that Saddam Hussein was able to remain in power. A stalemate is not an acceptable solution.
        AZUZ: Our next story today: whether it's a military situation, like in Libya, economics, or even something environmental, you know that events in one country can have an impact around the globe. Now, that includes the damage to a nuclear power plant in Japan. Brian Todd explains how what's happening at the Fukushima Daiichi nuclear plant in Japan is starting to show up in the United States.
        (BEGIN VIDEO)
        BRIAN TODD, CNN CORRESPONDENT, WASHINGTON, D.C.: Tiny amounts of radioactivity from Fukushima have now traveled at least halfway across the world, as far as America's East coast. Particles, believed to have come from Japan, have been detected in the air or in rainwater in at least a dozen states. Is it a health risk? Government officials say the levels are far lower than the amount that would pose any concern, sometimes thousands of times less. We caught up with the health director in Maryland, where radiation from Fukushima was detected in the air and rainwater.
        What does it mean overall that this has traveled all the way from Japan to now the East coast of the U.S.?
        DR. JOSHUA SHARFSTEIN, MARYLAND SECRETARY OF HEALTH: Well, you know, it shows that an environmental event in one part of the world can have, can be seen, sort of the echoes of it, in other parts of the world. And when Chernobyl happened, a similar thing was seen. When radioactive material gets into the atmosphere and can travel around into the weather patterns, it gets diluted as it goes along. And by the time it gets to a place like Maryland, it's so small it's not a public health concern.
        TODD: So far, no radioactive material has been found in drinking water or milk supplies in the U.S. The federal government is monitoring radiation as well.
        We're on a rooftop in Washington where the EPA has given us access to a RadNet fixed-air monitor. There are 124 of these across the U.S. It's a high-volume monitor. It measures three times the amount of air in one hour that we breathe in in one day. The air is sucked in under here and deposited on a filter right here, but measured with a gamma monitor and a beta monitor. Those measurements are transferred to a computer inside here where officials can come in and look at it in real time. That real-time data is transferred to a U.S. government lab in Alabama through this satellite dish right here, a cell-phone transmission there, and also a fixed-phone transmission. But officials do come up here and change the filter every couple of days, also to get more sensitive and accurate, redundant information. Brian Todd, CNN, Washington.

        Shoutout
        TOMEKA JONES, CNN STUDENT NEWS: Today's Shoutout goes out to Mr. Hudson's social studies classes at Bedford Middle School in Bedford, Indiana! What would you find at the latitude of 90º North? Here we go. Is it the: A) North Pole, B) Cape Horn, C) Tropic of Capricorn or D) Antarctic Circle? You've got three seconds -- GO! If you were standing at 90 degrees North latitude, you'd be chillin' at the North Pole. That's your answer and that's your Shoutout!
        Arctic Study
        AZUZ: At 90 degrees North latitude, the North Pole is in the Arctic Ocean. This is an ocean that is covered in ice. And scientists who study the Earth's climate want to know what happens when the ice from that ocean melts. So in order to do this study, they've set up a base in the Arctic Circle, where the temperature gets down to 40 degrees below zero. CNN has a camera crew there to cover this research project. And this is awesome, because it's the closest we have ever come from actually broadcasting from the North Pole. Scientist Phillipe Cousteau tells us what the research is all about.
        PHILIPPE COUSTEAU, CNNI SPECIAL CORRESPONDENT: Well, we're here for a week with the Catlin Arctic Survey, which is a group of scientists that are looking at various different issues to understand how the Arctic system works, how the ecosystem and the environment works here, what's happening with the trend of getting icecaps, with the uptake of carbon in the environment with ocean identification, with salinity changes, really to try and get a bigger picture and a more complete picture of what's happening with respect to the health of this environment that is so important to everybody on the entire planet.
        I think a lot of people forget that the Arctic really, in a sense, is the air-conditioning unit of the planet, and it matters to every single one of us. So, understanding what is happening here and in science of what is happening here is very critical.
        AZUZ: You got into college -- congratulations! I remember an acceptance letter I got once that said that just a few years ago. Man, it felt great. And it's what a lot of you seniors are looking for right now: that acceptance letter. But the question that many people are trying to answer is how do you pay for college once you get in? The senior that's featured in this next report from Christine Romans is weighing all of her options.
        (BEGIN VIDEO)
        OLIVIA POGLIANICH, STUDENT: I am in the process of waiting. Waiting. That's all I can say.
        CHRISTINE ROMANS, CNN ANCHOR: Eighteen-year-old Olivia Poglianich is waiting to find out if she's been accepted or not.
        CLAUDIA POGLIANICH, OLIVIA'S MOTHER: I got the letter that stated everything they need and they have reviewed, and the package should hopefully come.
        O. POGLIANICH: Yes, so now they're ready.
        ROMANS: A straight-A student, this senior at a Long Island high school has applied to 15 schools. But Olivia, like millions of others, faces another challenge: how to pay for her education. Money matters as much as grade point average.
        O. POGLIANICH: Affordability is a major part of my decision. For the next four years, will the financial aid from the nation, will that continue throughout the four years?
        ROMANS: Olivia has filled out the FAFSA form, which stands for the Free Application for Federal Student Aid. It helps decide billions of dollars of student financial aid. Olivia is also a Quest Bridge Scholar, which helps students apply for various college scholarships. But many don't know about their options. Princeton Review publisher Robert Franek says do as much research as possible and start early.
        ROBERT FRANEK, PUBLISHER, PRINCETON REVIEW: Lots of students and families were making a mistake early on in their college research. And this mistake was crossing an expensive school off of their list of consideration early on without following through and finding out how much financial aid that school is actually giving out.
        ROMANS: Olivia's mother was involved from the start.
        C. POGLIANICH: Everything is very time sensitive, and the sooner the paperwork gets in, the money's kind of divied out on a first come, first served basis. So, you really have to be on top of your paperwork and your taxes and have everything in on time.
        O. POGLIANICH: You just ask every college specifically, because even after asking the general questions, the specific requirements of one particular school differ greatly from another school.
        ROMANS: As April 1st draws closer, Olivia and her mother are nervous and hopeful.
        C. POGLIANICH: Reach for the sky. Reach for the sky.
        O. POGLIANICH: I'm excited to be going to college. No matter where I go, I'm actually pretty happy about my future.

        Before We Go
        AZUZ: Almost have today's show all wrapped up, but before we go, we have a tennis story for you, and we're going back to the fundamentals. Backhand, forehand, volley. Okay, this is not the most exciting tennis match ever played. But it is, believe it or not, the longest! High school seniors Sam and Katie stepped on the court Friday morning, and they didn't stop playing until Sunday night. Do the math: That is nearly 61 hours of tennis they played! If they got tired, I guess they just had to rally. The goal of this -- you see him having a drink of juice there to keep going -- the goal was to set a new world record.
        Goodbye
        AZUZ: And we're not gonna string you along about this. Sam and Katie caused a racket in the record books. The previous title holders got served! Game, set, match! Hopefully you won't fault us for any of those puns. We were having a ball with them. And hopefully, we'll see you back here tomorrow, when we net more stories on CNN Student News. Bye bye!

        奥巴马:美为阻止“屠杀” 才参与利比亚军事行动
        美国总统奥巴马为美军参与利比亚军事行动辩护,称这么做阻止了利比亚发生“屠杀”事件,但他也同时承诺美国不会重蹈在伊拉克的覆辙,为了推翻利比亚政权而陷入旷日持久的战争中。
        奥巴马周一晚在华盛顿的国防大学,就利比亚局势向全国发表电视讲话。针对许多国会议员指他没有向美国人民充分解释,美军在空袭亲卡达菲部队的行动中,扮演怎样的角色,奥巴马说,他别无选择必须采取行动,以避免利比亚人民遭遇“可怕的暴力”。
        他说:“身为总统,我拒绝等到屠杀和万人坑的画面出现在眼前后才采取行动。”
        这是联军对利比亚发动空袭的10天以来,奥巴马首次详细列明其军事策略。他说:“我们拥有阻止暴力的特有能力,也获得国际社会的授权采取行动,而广泛的盟友也准备助我们一臂之力……我们也有能力阻止卡达菲部队继续挺进。”
        不过,奥巴马也为美军展示能力设限,清楚表明华盛顿不会“一旦发生压迫事件”就担任世界警察。这意味着会避免在其他中东热点地区卷入军事纠纷。
        随着北约部队周三从美军手中全面接管利比亚军事行动的指挥权,奥巴马誓言,美军会把参与度限制在扮演“支援角色”。不过,奥巴马没有说明军事行动将在何时或如何结束。
        他承诺与盟友合作,促使卡达菲更快交出政权。但他说,他不会使用暴力来推翻卡达菲,就像美国前总统布什在2003年向伊拉克发动战争推翻萨达姆政权那样。奥巴马说:“我们在伊拉克走的就是这条路……让这种事在利比亚重演,我们承受不起。”
        美国多处监测到微量放射物
        日本福岛第一核电站发生核泄漏事故半个多月以来,其影响逐渐波及全球其他地区,美国多处监测站的大气、雨水样本中也陆续发现微量放射物。不过,美国相关政府机构和专家认为,微量放射物不会影响民众健康。
        美国最早监测到可能来自日本的微量放射物是在本月中旬。美国环保署和能源部18日联合发表声明说,美国西海岸已发现可能来自日本的放射性物质,不过剂量“极小”。此后,美国越来越多的监测站监测到放射物。本月26日,美国内华达州沙漠研究所社区环境监测项目负责人特德·哈特韦尔表示,位于赌城拉斯韦加斯原子弹试爆博物馆的一个监测站日前监测到极微量的放射性同位素碘-131和氙-133。
        目前,美国监测到放射物的州至少已有7个,但放射物含量都非常低,还不到威胁公众健康的程度。
        科学家猜测北极首个臭氧洞形成 皮肤癌危险提升
        据国外媒体报道,最新研究发现,在诡异的冷温辅助下,这个冬天同温层危险的“美丽”云状物剥去了北极大气层中具有保护作用的臭氧层。科学家猜测北极第一个臭氧洞或已形成。
        所谓的臭氧洞,又称臭氧层空洞,是大气平流层中臭氧浓度大量减少的空域,如著名的南极臭氧洞。有专家警告皮肤癌危险或将提升,低浓度臭氧地带范围向南最远已经到达了纽约上空。同温层中包含着臭氧层,它像一块毯子覆盖在地球上空,为地球阻挡来自太阳的大部分高频紫外线,这些紫外线会伤害地球表面,同时会晒伤人类皮肤,甚至引起皮肤癌。
        据悉,早在20世纪80年代,科学家们就意识到氯氟烃和其他对臭氧有害的化学物质正在侵蚀着臭氧层,这些化学物质被广泛运用于发胶和制冷剂等物品中。1987年签订的蒙特利尔议定书(Montreal Protocol)要求全球逐步淘汰氯氟烃,用其他不会破坏臭氧层的物质来代替它。然而,已经存在于大气中的氯氟烃能停留好几十年。据了解,氯氟烃一旦到达上层大气就会分解成氯原子,当被阳光激活,它就会破坏臭氧分子。冷温能够通过极地的同温层“云状物”加速这个过程,这些“美丽”云状物会在同温层温度降低到至少华氏温度零下108度(零下78摄氏度)时形成,给未被激活的氯物质提供庇护所,在这些云状物的表面,氯物质互相之间发生反应,释放具有“攻击性”的氯原子,攻击臭氧分子。一旦气温回暖,这个过程就会停止。
        德国阿尔佛雷德?韦格纳极地及海洋研究所(Alfred Wegener Institute for Polar andMarineResearch)的物理学家马库斯?雷克斯(Markus Rex)认为,北极上空持续的结冰天气可能已经将臭氧层标准浓度减少至原来的一半。根据北极地区30所臭氧监测站的初始数据显示,这个冬天臭氧损失情况要比以前严重得多。雷克斯猜测,在春天来临之前,“北极第一个臭氧洞可能已经形成,这可能将载入史册。”对此,国家大气研究中心(National Center for Atmospheric Research)的大气化学家西蒙尼?迪尔梅斯(Simone Tilmes)也表示同意。他并未参与到这次研究中,他称:“我们现在并不知道北极臭氧洞将发展到多大,因为臭氧层日益变薄的事情正在发生。
        当然,上述观点仍只是猜测,完全的确认需要经过计算机模拟和卫星测量。
