During climb out from ZZZ; passing FL270; noticed arcing at the top of the captain's #1 window. Upon closer inspection; arcing was actually running in a hairline crack in what appeared to be the outer pane. The arcing and cracking spread rapidly across the top of the windscreen. Then the outer pane shattered. We immediately leveled off; slowed the jet; ran the red tabs; and declared an emergency. A turn direct ZZZ and a lower altitude was accomplished. Fuel weight was adjusted in the descent to ZZZ. Uneventful landing at ZZZ.
