Bush's Climate Summit Leaves Much To Do

TOYAKO, Japan (AFP) - US President George W. Bush's last Group of Eight summit only inched forward the fight against climate change but drew the battle lines more sharply than ever between rich and poor nations.

The G8 major industrial powers agreed at a three-day summit in northern Japan to cut carbon emissions blamed for global warming by at least half by 2050, the strongest language yet signed by Bush.

But developing nations shot back by insisting that rich countries were most to blame for climate change and needed to commit to bigger and quicker emissions cuts.

Australian Prime Minister Kevin Rudd, who took part in an expanded 16-nation summit on climate change on Wednesday here in the secluded mountain resort of Toyako, said that it failed to reach a needed consensus.
