"Whether Barack Obama or Mitt Romney finds himself working from the Oval Office over the next four years, he will face the problem of tackling global warming without breaking the bank. He will have to realize that ignoring the problem will not make it go away -- but will also have to accept that the policies of the past 20 years have not worked.
Those policies, like the pledges to reduce carbon emissions at innumerable global conferences -- from Rio de Janeiro in 1992 to Kyoto in 1998 to Durban in 2011 -- have failed to tackle global warming. The total efforts of the last 20 years of climate policy has likely reduced global emissions by less than 1 percent, or about 250 million metric tons of carbon dioxide per year. Even if this decrease were attained for 100 years, it would reduce the temperature increase at the end of the century by an immeasurable one-hundredth of a degree Fahrenheit. The seas would rise about one-twentieth of one inch less."..................
