G8 set new climate targets

Leaders of the G8 leading industrial countries have agreed to try to limit global warming to just 2C (3.6F) above pre-industrial levels by 2050.

The summit, in the Italian city of L'Aquila, also set tough new targets for carbon emissions considered necessary to achieve the goal.

Developed nations are to cut carbon emissions by 80% by 2050, to allow a global 50% reduction by the same date.
