:00:10. > :00:13.Hello, I'm Hayley, he's Ore and this is Newsround. We're live, and
:00:13. > :00:17.here's what's on the way: Disaster in New York as the
:00:17. > :00:20.superstorm hits the city. The new technology that's G-ing up
:00:20. > :00:30.your mobile phones. And the new BBC show taking us to
:00:30. > :00:43.
:00:43. > :00:47.uncharted Arctic waters. You're First - floods, fires and 7 million
:00:47. > :00:52.homes have been left without power. Superstorm Sandy has swept across
:00:52. > :00:55.the east coast of America, leaving destruction behind it. 20 people
:00:55. > :00:59.have died in what's been described as the worst storm to hit America
:00:59. > :01:03.for years. Massive storm waves left parts of New York City under water,
:01:03. > :01:13.and President Obama said it was a major disaster for the city. I've
:01:13. > :01:16.been looking back at what happened when the storm hit land. This
:01:16. > :01:21.morning nearly half of New York City in the dark and under water.
:01:21. > :01:26.Lights out in the city that never sleeps.
:01:26. > :01:30.A record 4 metre wave sent water pour into tunnels and the Subway.
:01:30. > :01:35.It is like something out of a movie really. There's nobody on the
:01:36. > :01:41.streets. There's trees everywhere, road signs hanging down. What's
:01:41. > :01:50.going on? I don't know, it's a hurricane! A power station exploded
:01:50. > :01:55.in the east of the city and in the area of Queens 50 homes caught fire.
:01:55. > :02:00.There are numerous people trapped there, water going in the block,
:02:00. > :02:04.waist-high. We got in a boat and went down there. You would never
:02:04. > :02:09.think this would happen in New York. The storm blew the entire wall off
:02:09. > :02:13.this building. Newborn babies were among the
:02:13. > :02:16.patients that had to be evacuated from this hospital. Extraordinary
:02:16. > :02:23.pictures of a large tanker ship washed up on the shores of Staten
:02:23. > :02:28.Island. The state of New Jersey was the first place on the US East
:02:28. > :02:33.Coast to be hit by Sandy. The worst storm that has ever hit Atlantic
:02:33. > :02:39.City. This city is under water. York's Mayor says the worst has
:02:39. > :02:41.passed the city. But as the storm heads north towards Canada the
:02:41. > :02:44.damage done by Sandy definitely isn't over.
:02:44. > :02:47.The storm did lose some of its strength by the time it reached
:02:47. > :02:51.land, but it's still one of the biggest the country has experienced
:02:51. > :02:54.in years. To give you a sense of how big it really was, look at this.
:02:54. > :02:58.This picture of the storm was taken yesterday from space. If we put it
:02:58. > :03:04.over a map of Europe, you can see that it's so large, it covers not
:03:04. > :03:07.just the UK, but the whole of the Continent. We've spent the
:03:07. > :03:10.afternoon speaking to people in New York, trying to find out the
:03:10. > :03:13.situation there. Yesterday we heard from Ella and her brother, Armando,
:03:13. > :03:23.who live in Brooklyn. Today they told us how they prepared for the
:03:23. > :03:25.
:03:25. > :03:31.storm. We have big buckets and we made sure we filled them, first
:03:31. > :03:37.cleaned them out and filled them with clean water. Also, we made
:03:37. > :03:44.sure our batteries were full and candles, because if the power falls
:03:44. > :03:50.off... I had a friend, where she lived, her house was full of water.
:03:50. > :03:54.I saw seven trees fall. Big trees. Yesterday I couldn't go out because
:03:54. > :03:58.it was too dangerous. It is not just American who is have
:03:58. > :04:02.been affected. A group of kids from a school in Caerphilly in Wales
:04:02. > :04:10.were on a half-term trip to New York when the storm struck. They've
:04:10. > :04:14.been stuck in their hotel. whole city was on lockdown, so
:04:14. > :04:20.there was no public transport. There were no shops open, so we
:04:20. > :04:22.couldn't go out shopping. It was quite scary, to be honest. We all
:04:22. > :04:27.looked after each other and slept in a big room together. The
:04:27. > :04:31.teachers have been fantastic. quite a bit calmer today, although
:04:31. > :04:36.there's more rain. The winds have dropped significantly.
:04:36. > :04:41.We are hoping to be able to go outside tonight just for a little
:04:41. > :04:46.walk, because we've been cooped up in these rooms.
:04:46. > :04:49.Moving on now, and if you're sick of it taking ages when you want to
:04:49. > :04:52.watch a video on a phone, listen up, because the future of faster mobile
:04:52. > :04:55.technology has arrived. It's called 4G and has been launched today by
:04:55. > :05:02.the company EE, which owns Orange and T-Mobile. But as I've been
:05:02. > :05:07.finding out, not everyone's going to be able to use it straight away.
:05:08. > :05:11.Welcome to the next generation. 4G is all about speed. Making it much
:05:11. > :05:17.quicker and easier for tow download and watch things live on your phone.
:05:17. > :05:22.The internet is a lot faster on 4G, superfast. On 3G it is still fast
:05:22. > :05:32.but not as fast. Give me an example, how fast are we talking? If you
:05:32. > :05:33.
:05:33. > :05:37.wanted to load a outvideo, on a 4 - - load a YouTube video, on a 4G
:05:37. > :05:42.phone just 30 seconds. But not everyone will be able to get it at
:05:42. > :05:47.first. It has gone live in 11 UK cities. You will only get it if you
:05:47. > :05:52.are with two networks - Orange and T-Mobile. Next year it should be
:05:52. > :05:55.available in more place and on more networks. A mobile network is a bit
:05:55. > :05:59.like a road with traffic on it. The more information you send down it,
:05:59. > :06:04.the more traffic jams you get. Lots of people use 3G at the moment, so
:06:04. > :06:08.it is often slow to download music and videos, but the 4G network is
:06:08. > :06:13.like a much wider motorway, with more lanes, so you should be able
:06:13. > :06:18.to do these things up to five times faster. But that speed comes at a
:06:18. > :06:21.cost. The cheapest contract is �36 a month that. Gives you 5 00
:06:21. > :06:26.megabytes of download, roughly three episodes of Doctor Who off
:06:26. > :06:29.the iPlayer. But if you want more, you are charged extra. It is fast,
:06:29. > :06:36.there is no doubt about that. There are some challenges though. It is
:06:36. > :06:40.quite bad at getting into buildings, your coverage might drop off
:06:40. > :06:46.indoors. It doesn't cover the whole country. And if you have a 3G phone,
:06:46. > :06:49.you might get the same performance as you do on 4G for much less money,
:06:49. > :06:53.as the networks are upgrading. We'll have to see how many people
:06:53. > :06:56.pay for it now and if it will make the future faster.
:06:56. > :06:58.The Arctic is one of the most uninhabitable places on the planet,
:06:58. > :07:01.but this summer a team of scientists and adventurers braved
:07:01. > :07:02.the freezing temperatures to uncover new secrets about the icy
:07:02. > :07:05.landscape. During their investigations they discovered some
:07:05. > :07:08.polar bear families living on floating icebergs. But there are
:07:08. > :07:18.worries that with the ice melting fast, the future of these animals
:07:18. > :07:20.
:07:20. > :07:25.could be in danger. Abseiling into an ice cave, sleeping on an iceberg
:07:25. > :07:30.surrounded by polar bears, and trying to escape massive tidal
:07:30. > :07:37.waves. All sounds pretty dangerous, but that's exactly what one team of
:07:37. > :07:42.explorers have been doing for a BBC show, Operation Iceberg. Wow! Look
:07:42. > :07:46.at that! A wall of ice is splitting from the glacier. Compared to
:07:46. > :07:51.anything the team has seen before, this is vast.
:07:51. > :07:55.One of the most interesting things the team are reporting is that
:07:55. > :07:58.within the next few decades the ice in the Arctic could disappear
:07:58. > :08:01.completely during the summertime, which would mean that one of the
:08:01. > :08:06.most recognisable inhabitants of the region wouldn't have anywhere
:08:06. > :08:11.to live. This is all my Christmass come it's a once - a polar bear. I
:08:11. > :08:16.really, really, really hoped to see one but I never thought we would.
:08:16. > :08:20.The polar bear seems to be adapting to the changing landscape, but what
:08:20. > :08:23.might be the first time the team found a large number of the bears
:08:23. > :08:27.living on floating ice during the summer months. Before now it was
:08:27. > :08:33.thought all polar bears leave the ice during the summer, moving to
:08:33. > :08:37.the lands. Now it is clear that some stay out at sea surviving on
:08:37. > :08:41.large icebergs We saw eight in the first day. They created their own
:08:41. > :08:45.problem, because we couldn't stay too long on the iceberg. We need to
:08:45. > :08:49.put bear watchers tout make sure the bears weren't approaching too
:08:50. > :08:56.close, as we are a food source to them. You can find out more about
