Rich countries like the UK have to redouble their efforts to reduce greenhouse emissions and must aim to make cuts of at least 80 per cent by 2050, says Christian Aid, responding to the latest UN global warming report.

As the Intergovernmental Panel on Climate Change publishes its new report on economics and control of emissions, climate change activists say the UN Bangkok meeting is a step forward but not enough. Churches are taking up the cause.

Scientists' grim predictions of an even worse rate of global warming means the world must act immediately to help poor people cope with the now inevitable ravages of climate change, says international development agency Chrsitian Aid.

The World Council of Churches (WCC) programme on climate change and water has welcomed a high-profile report released today by the United Nations climate panel. The WCC brings together mainline Protestant, Orthodox, Anglican and indigenous churches across the world, working closely with Roman Catholics and in exchange with Evangelicals and Pentecostals.
