Kyoto: dead or alive?

It's fifteen years since the world pledged for the first time to reduce greenhouse gas emissions. The Kyoto Protocol, which called on countries to cut pollution levels by 5% by 2012, has seen some success in Europe. But with its expiry date fast approaching, the pressure is on world leaders to thrash out a new agreement to succeed Kyoto - but it won't be easy, since some of the world's biggest players, such as the United States, are opposed to the plan.

We also take a look at how climate change is having an effect on the planet. Scientists in France believe that global warming could wipe out 10% of the world's species. That's following research being done in the south of the country, where a laboratory is simulating climate change and measuring the effects on the animals and insects inside.

Finally, we visit what used to be the island of Lohachara in India's Ganges delta. It's now underwater, although a sandy strip often appears above the surface. There's some dispute over whether it was flooded because of global warming, but that's little consolation to the former residents, forced to flee their homes because of the rising waters.
