G8 agree on 2 degree Celsius limit

L’AQUILA, Italy — President Barack Obama and other leaders at the Group of Eight summit have struck a new agreement on fighting global warming.

The leaders said in a statement at their summit in Italy that their goal was to keep temperatures from rising more than 2 degrees Celsius.

Climate change experts have said such an acknowledgement was significant because the G-8 has never prounouced itself on that temperature goal.
