In a 5-to-4 ruling this week, the US Supreme Court ruled against the EPA's regulation of toxic emissions from coal and oil-fired power plants. For the majority, Justice Antonin Scalia said the monetary cost to power-plant operators was not worth "a few dollars in health or environmental benefits." That could mean trouble for President Obama's clean air agenda.
Meantime, a Dutch court says its government must increase cuts in emissions -- regardless of cost -- in the interest of health and safety. Conflicting court rulings dramatize conflicting approaches to the environment and global warming.
