Time for Plan B: Cutting Carbon Emissions 80 Percent by 2020
When political leaders look at the need to cut carbon dioxide emissions to curb global warming, they ask the question: How much of a cut is politically feasible? At the Earth Policy Institute we ask a different question: How much of a cut is necessary to avoid the most dangerous effects of climate c...
