Report shows UN admitting solar activity may play significant role in global warming.

The Earth has been getting warmer — but how much of that heat is due to greenhouse gas emissions and how much is due to natural causes? A leaked report by a United Nations’ group dedicated to climate studies says that heat from the sun may play a larger role than previously thought.
