Mount Everest getting smaller?

Just how tall is Mount Everest?
The world's tallest mountain, Everest is to be re-measured after a recent survey suggested the summit is getting smaller because of global warming.

In March, a Chinese climbing team will use satellite and radar technology to find out its actual height.

The size of Everest has been in debate since it was first measured in 1856 as 8,839 metres tall.

But in 1954 an Indian survey recorded 8,848m but in 1999 a US study suggested it was two metres higher.

Whatever the team discovers, the movement of the earth's tectonic plates, means Everest's height changes a little each year.
