As the world prepares for this December’s crunch UN summit in Copenhagen, two of the Church of England’s leaders are to join forces with Operation Noah, and ecumenical organisation that campaigns on climate change.

Operation Noah has launched a Church Action Starter Pack for communities wanting to learn and take action on climate change.

A Lightship owned by Cardiff’s churches is being transformed into Noah’s Ark by the city’s children in a bid to tell UK leaders that they must act urgently to protect human and animal life on the planet.

Christians have been urged to opt for "low-carbon living" within "a web of fossil fuel existence" as many poor countries such as Bangladesh experience the negative aspects of human-induced global warming.

Abbot Christopher Jamison, star of the BBC television series The Monastery, has warned that rampant consumer culture is taking over people's moral purpose, and must be tackled in order to address climate change.

What may be, size-wise, the largest petition ever handed in to any British Prime Minister will be presented at Number 10 Downing Street by Christian environmental campaigners tomorrow.
