A demonstration has taken place in Dublin today to mark an international day of action on climate change.

Bells from churches across the country rang at 2pm, signalling concern that global warming could soon have irreversible impacts. 

Today's demonstration coincides with a gathering of the world's Environment Ministers in Indonesia, where they will try to agree a road-map for negotiations on a successor to the Kyoto Protocol.

According to the UN, two degrees is the tipping point after which rising global temperatures are likely to have irreversible impacts.

In Dublin, a demonstration went from Wood Quay to the Department of the Environment at the Custom House.

The organisers, Stop Climate Chaos, say they hope it will be a wake-up call for all politicians to do more to tackle the problem.

The 'Sound the Alarm' event was organised by Christian Aid, Trocaire, Friends of the Earth and Eco-congregation.
