COP21: Rhone Glacier drone footage shows ice retreat

Diplomats and climate experts are to meet in Paris for the UN Conference on Climate Change, aiming to secure a new global deal that would limit emissions of carbon dioxide.

For many of us the impact of climate change can often seem distant and difficult to visualise - but that is far from the case in Switzerland.

There, a temperature rise of 2C in the last 150 years has led to a rapid acceleration in the melting of the country's glaciers.

If greenhouse emissions continue to rise according to current trends, all of the large masses of ice in the Swiss Alps will have almost vanished by the end of the century, scientists warn.

BBC video journalist Howard Johnson travelled to the Rhone Glacier, which has receded by 30m in the last year alone.

He met glacier expert Dr David Volken who set out the evidence for the ice sheet's retreat - and why the world should sit up and pay attention.

Primates need protecting scientists warn

Scientists have called for governments to do more to protect primates.

It's unknown how many Red ruffed lemurs are left in the wild.

It's after warning that more than half the world's primate population is facing extinction.

A new list of the world's 25 most endangered primates has been published.

The population has been decreasing for a number of reasons.

Including the burning and clearing of tropical forests.

As well as being hunted for food or for use in traditional medicine in Asia .

There are more 700 different types of primates in the world.

The Philippine tarsier and the Lavasoa Mountains dwarf lemur from Madagascar have been added to the list for the first time.

The hope is to convince governments across the world to look at ways of better protecting habitats and the animals.

One of the world's last northern white rhinos dies in the US

An extremely rare northern white rhino has died in the US, leaving only three others in the world.

Nola was one of four northern white rhinos left in the world.

The 41-year-old rhino, Nola, died after surgery to her hip at San Diego Zoo.

Nola's death means that there are only three other northern white rhinos in the world.

They live in Kenya and are kept closely guarded.

Nola had surgery on 13 November but her health got worse.

Poachers have been blamed for the devastating drop in northern white rhino numbers.

They kill many rhinos to get their horns, which are worth a lot of money in some cultures.

However, there is hope that there may be more northern white rhinos born in the future.

San Diego Zoo has recently brought in six southern white rhinos, hoping to use them as mothers to new northern white rhino calves.
Zoo researchers are still working out if it's possible, but they say they're hopeful that a northern white rhino calf could be born within 10 to 15 years.
