In recent days, the Archbishop of Canterbury, Ecumenical Patriarch Bartholomew and Pope Francis have all spoken out on the vital issue of climate change. It is vital, because the long-term future of the Earth and its inhabitants is at stake. It is no less a matter than that.
The issue of climate change led to the landmark Rio Earth Summit in 1992, which set out a framework for action aimed at stabilising atmospheric concentrations of greenhouse gases to avoid dangerous interference with the climate system. What is termed the Conference of Parties (COP) regularly reviews the implementation of the Rio action programme. The next COP will be held next December in Paris and, for the first time in two decades of UN negotiations, will seek to achieve a legally binding and universal agreement on climate, aiming to keep global warming below 2Â°C.
