BBC: Negotiators are currently gathered in Lima, Peru, for this year’s UN Climate Change Conference. The goal of the meeting, which is being held 1–12 December, is to reduce global greenhouse gas emissions and limit global temperature rise to 2 °C. For the first time, senior officials of the Roman Catholic Church are weighing in on the negotiations, calling for an end to fossil fuel use, the phasing in of 100% renewable energy, and an even stricter limit to global temperature rise of just 1.5 °C. According to Monsignor Salvador Piñeiro García-Calderón, Archbishop of Ayacucho and president of the Peruvian Bishops’ Conference, the church feels an obligation to protect the planet and its inhabitants, especially the poorest people, who are affected the most by climate change yet have contributed the least to the problem.
