Rich nations' climate plans fall short of hopes for Paris summit

Developed nations are on track to cut their greenhouse emissions by almost 30 percent by 2030, Reuters calculations show, falling far short of a halving suggested by a U.N. panel of scientists as a fair share to limit climate change.
Last year the U.N.‘s Intergovernmental Panel on Climate Change (IPCC) said rich nations that were members of the Organisation for Economic Cooperation and Development in 1990 should halve emissions by 2030 from 2010 to limit warming.
A Climate Action Tracker […] estimates that current pledges put global temperatures on track to rise by 3.1 Celsius by 2100, threatening ever more droughts, floods, heat waves and rising sea levels.
