The most important climate conference ever, has kicked off in Paris. COP21, the 21st Conference of the Parties, entered its first full session yeterday with nearly 150 heads of state in attendance. The overarching goal of COP 21 is to create a global framework for countries to reduce their carbon emissions, so that the average global temperature does not increase by more than 2°C. The UN's climate agency says an increase greater than that will be catastrophic for the world's life support systems. Oceans will warm and storms will become more frequent and damaging. Sea levels will rise and ice caps will melt. Sakina Kamwendo author and authority on Climate Change, Professor Patrick Bond.
