Hello, I'm Hayley, he's Ore and this is Newsround. We're live, and

here's what's on the way: Disaster in New York as the

superstorm hits the city. The new technology that's G-ing up

your mobile phones. And the new BBC show taking us to

uncharted Arctic waters. You're First - floods, fires and 7 million

homes have been left without power. Superstorm Sandy has swept across

the east coast of America, leaving destruction behind it. 20 people

have died in what's been described as the worst storm to hit America

for years. Massive storm waves left parts of New York City under water,

and President Obama said it was a major disaster for the city. I've

been looking back at what happened when the storm hit land. This

morning nearly half of New York City in the dark and under water.

Lights out in the city that never sleeps.

A record 4 metre wave sent water pour into tunnels and the Subway.

It is like something out of a movie really. There's nobody on the

streets. There's trees everywhere, road signs hanging down. What's

going on? I don't know, it's a hurricane! A power station exploded

in the east of the city and in the area of Queens 50 homes caught fire.

There are numerous people trapped there, water going in the block,

waist-high. We got in a boat and went down there. You would never

think this would happen in New York. The storm blew the entire wall off

this building. Newborn babies were among the

patients that had to be evacuated from this hospital. Extraordinary

pictures of a large tanker ship washed up on the shores of Staten

Island. The state of New Jersey was the first place on the US East

Coast to be hit by Sandy. The worst storm that has ever hit Atlantic

City. This city is under water. York's Mayor says the worst has

passed the city. But as the storm heads north towards Canada the

damage done by Sandy definitely isn't over.

The storm did lose some of its strength by the time it reached

land, but it's still one of the biggest the country has experienced

in years. To give you a sense of how big it really was, look at this.

This picture of the storm was taken yesterday from space. If we put it

over a map of Europe, you can see that it's so large, it covers not

just the UK, but the whole of the Continent. We've spent the

afternoon speaking to people in New York, trying to find out the

situation there. Yesterday we heard from Ella and her brother, Armando,

who live in Brooklyn. Today they told us how they prepared for the

storm. We have big buckets and we made sure we filled them, first

cleaned them out and filled them with clean water. Also, we made

sure our batteries were full and candles, because if the power falls

off... I had a friend, where she lived, her house was full of water.

I saw seven trees fall. Big trees. Yesterday I couldn't go out because

it was too dangerous. It is not just American who is have

been affected. A group of kids from a school in Caerphilly in Wales

were on a half-term trip to New York when the storm struck. They've

been stuck in their hotel. whole city was on lockdown, so

there was no public transport. There were no shops open, so we

couldn't go out shopping. It was quite scary, to be honest. We all

looked after each other and slept in a big room together. The

teachers have been fantastic. quite a bit calmer today, although

there's more rain. The winds have dropped significantly.

We are hoping to be able to go outside tonight just for a little

walk, because we've been cooped up in these rooms.

Moving on now, and if you're sick of it taking ages when you want to

watch a video on a phone, listen up, because the future of faster mobile

technology has arrived. It's called 4G and has been launched today by

the company EE, which owns Orange and T-Mobile. But as I've been

finding out, not everyone's going to be able to use it straight away.

Welcome to the next generation. 4G is all about speed. Making it much

quicker and easier for tow download and watch things live on your phone.

The internet is a lot faster on 4G, superfast. On 3G it is still fast

but not as fast. Give me an example, how fast are we talking? If you

wanted to load a outvideo, on a 4 - - load a YouTube video, on a 4G

phone just 30 seconds. But not everyone will be able to get it at

first. It has gone live in 11 UK cities. You will only get it if you

are with two networks - Orange and T-Mobile. Next year it should be

available in more place and on more networks. A mobile network is a bit

like a road with traffic on it. The more information you send down it,

the more traffic jams you get. Lots of people use 3G at the moment, so

it is often slow to download music and videos, but the 4G network is

like a much wider motorway, with more lanes, so you should be able

to do these things up to five times faster. But that speed comes at a

cost. The cheapest contract is �36 a month that. Gives you 5 00

megabytes of download, roughly three episodes of Doctor Who off

the iPlayer. But if you want more, you are charged extra. It is fast,

there is no doubt about that. There are some challenges though. It is

quite bad at getting into buildings, your coverage might drop off

indoors. It doesn't cover the whole country. And if you have a 3G phone,

you might get the same performance as you do on 4G for much less money,

as the networks are upgrading. We'll have to see how many people

pay for it now and if it will make the future faster.

The Arctic is one of the most uninhabitable places on the planet,

but this summer a team of scientists and adventurers braved

the freezing temperatures to uncover new secrets about the icy

landscape. During their investigations they discovered some

polar bear families living on floating icebergs. But there are

worries that with the ice melting fast, the future of these animals

could be in danger. Abseiling into an ice cave, sleeping on an iceberg

surrounded by polar bears, and trying to escape massive tidal

waves. All sounds pretty dangerous, but that's exactly what one team of

explorers have been doing for a BBC show, Operation Iceberg. Wow! Look

at that! A wall of ice is splitting from the glacier. Compared to

anything the team has seen before, this is vast.

One of the most interesting things the team are reporting is that

within the next few decades the ice in the Arctic could disappear

completely during the summertime, which would mean that one of the

most recognisable inhabitants of the region wouldn't have anywhere

to live. This is all my Christmass come it's a once - a polar bear. I

really, really, really hoped to see one but I never thought we would.

The polar bear seems to be adapting to the changing landscape, but what

might be the first time the team found a large number of the bears

living on floating ice during the summer months. Before now it was

thought all polar bears leave the ice during the summer, moving to

the lands. Now it is clear that some stay out at sea surviving on

large icebergs We saw eight in the first day. They created their own

problem, because we couldn't stay too long on the iceberg. We need to

put bear watchers tout make sure the bears weren't approaching too

close, as we are a food source to them. You can find out more about
