  • Theres a consensus among leading scientists that
    global warming is caused by human activity.
    Whatif anythingshould we do about it?
  •  
  • JEFFREY BALL Global warming is fundamentally
    harder than past environmental problems. Unlike
    smog or litter or dirty rivers, its global, long
    term and largely invisible. The upshot Solving
    global warming is the top priority of essentially
    no one (save a relative handful of scientists and
    environmental activists).

  • That suggests two basic principles for fighting
    global warming. First, the steps that will be
    most politically feasible are those that happen
    to curb greenhouse-gas emissions in the process
    of doing something that more people care more
    about cleaning the air, or producing jobs or
    making money. Second, in contrast to the approach
    taken thus far, the steps that make the most
    sense are the ones that are most economically
    efficient.
  • A third basic principle is equally important
    Technological breakthroughs are hard to predict.
    So its unwise to ground any strategy to curb
    global warming on the expectation that a
    particular technology will get big enough and
    cheap enough to be a main fix.

  • Those three basic principles are pretty general.
    They point to two more-specific approaches
  •  
  • Focus on the biggest sources of greenhouse-gas
    emissions. That includes a handful of gases
    produced in industrial processes that, pound for
    pound, pack a far heavier global-warming punch
    than does carbon dioxide. As for carbon dioxide,
    it means focusing on China, the worlds biggest
    emitter and a place that has an incentive to
    clean up its energy system that most people see
    as far more compelling than global warming dirty
    air.

5
  • And when governments around the world spend money
    to promote cleaner energy, its worth structuring
    those subsidies to reward not specific
    predetermined technologies, but whichever
    technologies over time end up able to produce the
    most environmental gain at the lowest cost.
