G8 negotiators reach tentative climate deal: sources

TOYAKO, Japan (Reuters) - Group of Eight negotiators have reached a tentative agreement on the wording of a statement on ways to fight global warming that will be put to their leaders on Tuesday morning, sources familiar with the talks said.

A statement that goes beyond last year's G8 summit pledge to "seriously consider" carbon emissions cuts of 50 percent by 2050 is especially important for Japanese Prime Minister Yasuo Fukuda, who has made climate change the centerpiece of the talks.

But efforts to clinch a deal have been hampered by deep differences within the G8. Details of the agreement, expected to be unveiled later on Tuesday, were not immediately available.
