You Can't Win

In the You Can't Win department, lower greenhouse gas emissions in the northeast might be a bad thing:

Greenhouse gas emissions from Northeast power plants were about 10 percent lower than predicted during the last two years, because of milder weather and increased reliance on natural gas instead of oil.

But the decrease may have some unanticipated consequences for efforts to combat global warming: It could have the perverse effect of delaying more lasting reductions, by undercutting incentives intended to spur power plants to invest in cleaner technologies and energy efficiency.
