The Lima Conference of the Parties (COP 20) continue their long-running failure to achieve any consensus about international collaboration to cut carbon emissions. Two very different commentaries are to be found from the BBC (12.12.14) on the one hand and from the Murgatroyd Blog (08.12.14) on the other hand. Another surprising contribution to the COP 20 debate came from an international declaration by Catholic bishops on climate change. They are the leaders of upwards of one billion adherents world-wide – around one seventh of all the people on Spaceship Earth. Jeremy Williams comments on and provides a link to this declaration.
