ScienceDaily: A Dartmouth-led study using a 600-year-old ice core shows that global mercury pollution increased dramatically during the 20th century, but that mercury concentrations in the atmosphere decreased faster than previously thought beginning in the late 1970s when emissions started to decline. The findings suggest that present-day efforts to cut mercury emissions will reduce pollution more quickly than current models predict. The study appears in the journal Environmental Science & Technology. ...

The court ruled in a 5-4 decision, with its five conservative justices in the majority, against the U.S. Environmental Protection Agency (EPA). The rule stays in effect for the time being, with...
