"The world needs a Plan B on climate change because politicians are failing to reduce carbon emissions, according to a UN report.
It warns governments if they overshoot their short-term carbon targets they will have to cut CO2 even faster in the second half of the century to keep climate change manageable"
And the Washington Post reports:
"At a meeting in Berlin, the U.N. Intergovernmental Panel on Climate Change (IPCC) on Sunday released a report that found that nations still have a chance to fulfill the goal but must aggressively turn away from relying largely on fossil fuels such as coal for energy and replace them with cleaner energy sources such as solar and wind power. To reach their target of 3.6 degrees (2 degrees Celsius) over preindustrial levels, nations must work together to lower emissions 'by 40 to 70 percent' of what they were in 2010, the report said."
