There is overwhelming evidence that human activities are mainly responsible for climate change since the mid-twentieth century, and urgent action is needed to tackle the problem, scientific experts have said.
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.
