Global warming's simple fix

Any lasting solutions will have to be extremely simple, and - because of the cost implicit in reducing the use and emissions of fossil fuels - will also have to benefit those countries that impose them in other ways. Fortunately, there is such a solution, one that is grippingly unoriginal, requires no special knowledge of economics and is easy for any country to implement. It's called a carbon tax, and it should be applied across the board to every industry that uses fossil fuels, every home or building with a heating system, every motorist and every public transportation system.

Immediately, it would produce a wealth of innovations to save fuel, as well as new incentives to conserve. More to the point, it would produce a big chunk of money that could be used for other things. Anyone for balancing the budget? Fixing Social Security for future generations? As a foreign policy side benefit, users of the tax would suddenly find themselves less dependent on Persian Gulf oil or Russian natural gas, too.
