Ricky here with your Newsround morning update. On the way: Find out

how Bao Bao the giant panda cub spent her first day outside. And the

tallest ferris wheel in the world. This is Newsround.

First, there are warnings that very high levels of air pollution will

spread across much of England and Wales over the next few days. This

week many people have found their cars covered in a mysterious layer

of fine dust. The South of England, and parts of Wales and Northern

Ireland have all been affected, and in London the fine sand floating in

the air has triggered one of the worst smogs of the year. It's all to

do with the Sahara desert, as BBC Weather Presenter Peter Gibbs

explains in this special weather report for Newsround.

This mystery dust has been reported all over the UK at the last two or

three days and it did actually come all the way from the Sahara desert.

Over the weekend we had an area of low pressure, a storm, in the

south-west of Europe which caused strong winds to develop over the

north-west of Africa where the Sahara desert is, and it is just

covered in dust and fine sand. The winds are strong enough to pick up

the dust and sand which is of a yellow colour and lift it high into

the atmosphere. It was transported by strong winds across Spain and

France, and once it reached the UK, it got mixed up with clouds, and the

rain fell with the dust which brought it down to the ground, and

when the rain evaporated we were left with the dust. It happens more

often than you thinkbut this was a particularly heavy fall.

A powerful earthquake has hit off the coast of northern Chile in South

America, triggering a tsunami alert. The quake happened overnight and

waves as high as two meters hit some areas. Tens of thousands of people

have been evacuated and a state of emergency has been declared. Five

people have been killed. These pictures of traffic jams as people

tried to leave were shown on Chilean TV. Next to what could be some good

news for Britain's bees. The Heritage Lottery Fund says it will

give over ?1 million to help schools do more to protect the country's bee

population. Bees have a huge impact on us because they help pollinate

crops like wheat and barley, as well as fruit trees. They're at risk of

extinction and over 200 schools will be given money to make their grounds

into pollinator-friendly spaces, so they're more attractive to the

insects. Let's get you some sport now and what could be a turnaround

in Manchester United's fortunes this season. They managed to hold the

reigning Champions Bayern Munich to a draw in the Champions League last

night. Nemanja Vidic headed David Moyes' side into the lead before

Bastian Schweinsteiger got Bayern a precious away goal. But he was later

sent off and will miss the second leg in Germany. Last night's other

quarterfinal also ended in a one-all draw. This fantastic strike from

Diego Ribas opened the scoring between Spanish giants Atletico

Madrid and Barcelona after nearly an hour's play. But Neymar got one back

later in the game to keep Barca in the tie. Chelsea will face the might

of Zlatan Ibrahimovic in France tonight for their quarterfinal,

against Paris St Germain. The French side look likely to win their second

league title in a row, mainly thanks to the genius of the Swedish

striker. Chelsea boss Jose Mourinho remembers Zlatan well, after

managing him at Inter Milan. In one year the relationship was

phenomenal, and when people say he is difficult personality, permit the

difficult personalities of the players who do not want to win all

work will be the best. He wants to win, work, the best. Fara

Williams's single Happy has sold more than a million copies in the

UK, and he has just been announced as a new judge on the US version of

the Voice. He will sit in the famous chair when the show starts again in

the year -- later in the year. Big wheel fans, I have a treat for

you now. The tallest Ferris wheel in the world has opened in Las Vegas in

America. It stands at an impressive 168 metres tall, about 33 metres

taller than the London Eye. The wheel has 28 glass pods which can

each hold up to 40 people. But it won't be the tallest wheel for long.

Two giant Ferris wheels are being built, one in New York City, and

another in Dubai in the Middle East. Finally, a giant panda cub called

Bao Bao who lives in a zoo in Washington DC, America has spent its

first day playing outside. Bao Bao tried out her climbing skills and

sat on the grass with a piece of bamboo. Zookeepers also fitted

barriers on trees to prevent the cub from climbing too high and put out

bales of hay to cushion any falls. That's all from me, Newsround's back

this afternoon. See ya!
