With fewer than 300 days until the long-awaited signing of a global pact to curb climate change, the world's nations remain deeply divided on fundamental issues. Most parties agree that overall global warming must be limited to two degrees Celsius (3.6 degrees Fahrenheit) over pre-Industrial Revolution levels, though small island states at highest risk of climate change-induced sea level rise want a lower ceiling of 1.5 C. One proposal in the framework text approved in Geneva on Friday is to reduce greenhouse gas emissions by 40-70 percent from 2010 levels by 2050 and near-zero emissions by 2100, as advised the UN's Intergovernmental Panel on Climate Change. The issue that permeates everything, "differentiation" is about how to share responsibility between rich and developing nations for cutting climate-damaging greenhouse gas emissions.
