Energy ministers from around the world met in London this week and got a scolding. The International Energy Agency warned the ministers that they are falling way behind in their efforts to wean the world from dirty sources of energy.

Dale Miller spends his days on the streets of downtown Denver selling a newspaper called The Homeless Voice. He's been having some health problems, but he can't afford to see a doctor on the $10 to $15 a day he makes selling papers.

A district judge ruled that Florida Gov. Rick Scott cannot mandate random drug testing for state employees.
