The Climate and the Cross: US evangelical Christians tussle with climate change

An internal battle is simmering among evangelicals in the US over whether climate change is a call to protect the Earth, the work of God to be welcomed, or does not exist at all.

Evangelicals have traditionally been the bedrock of conservative US politics, including on climate change. But a heated debate is taking place across the country, with some Christians protesting in the name of protecting the Earth, seeing it as a duty to be done in God's name. One group has even built a chapel in the way of an oil pipeline and a radical pastor has encouraged his congregation to put themselves in the way of the diggers.

But resistance remains - a climate scientist who denies the world is warming and a preacher in Florida who sees the fact his home was flood as a welcome sign of divine presence.

Could a surprising section of Christian Americans offer hope regarding the country's attitude to climate change?
