A National Renewable Energy Grid
With no national or world plan to rapidly phase out the burning of fossil fuels, greenhouse gases will go on increasing for decades. This will prevent any chance of restricting global temperature rise to 2 degrees. But as James Hansen bluntly states "The target that has been talked about in international negotiations for two degrees of warming is actually a prescription for long-term disaster."
Rises of 3 or 4 degrees are likely to lead to runaway and irreversible warming, especially with increasing methane release from permafrost and the ocean floor.
A national and international wind and solar transition plan is urgently needed and humanly possible.
