That warning comes from the today released World Wildlife Funds report "Climate Solutions 2: Low-Carbon Re-Industrialization",  aimed at showing what must be done if we are to avoid temperature increases of more than two degrees Celsius and large-scale climate catastrophe.

The report shows that greenhouse gas emissions must be reduced by 80% by the year 2050 to stop global warming from exceeding the critical two degrees. Meeting the goals requires that 95% of global energy production comes from renewable energy and that 9 of 10 power stations must have carbon storage, so-called CCS, at the beginning of 2013. It will also require a growth in the segments of solar, wind, biomass, geothermal, wave and hydropower of at least 25% per year until 2050.

Fields of energy efficiency, solar and wind power are highlighted as areas with special potential. For example could energy efficiency measures reduce energy demand by about 40% by 2050 and energy production from wind and solar power must reach the same volumes as the energy that today comes from nuclear power globally.

The huge investments, 7000 billion dollars, which will be needed by 2050 is estimated to be very profitable and provide a return about six times the capital invested, or 47 000 billion dollars in 2050.
