Christians set out on climate 'pilgrimage' from London to Paris

Members of different denominations embark on a two week long march to the Paris climate change talks to raise awareness of environmental issues

"Not getting lost in London will probably be the first hurdle," laughed Jade Till, a teacher from Stroud, before adding that walking 19 miles on a cold November day will also be a challenge.

Sat in the crypt of St Martin's-in-the-Fields on the edge of Trafalgar Square on Friday, Till was about to walk 200 miles to Paris on a two week "pilgrimage" to crunch UN climate change talks where world leaders aim to negotiate a new deal on limiting greenhouse gas emissions.
