COPENHAGEN (AP) - A leaked Danish document at the U.N. climate conference provoked angry criticism Tuesday from developing countries and activists who feared it would shift more of the burden to curb greenhouse gases on poorer countries.
Negotiators, meanwhile, displayed charts of data that said the current decade is on track to be the hottest on record for planet Earth.
At the heart of Tuesday's clash - stemming from draft texts attributed to Denmark and China - is the determination by the more impoverished states to bear a lesser burden than wealthy, more industrialized countries in the effort to slow warming.
Diplomats from developing countries and climate activists also complained the Danish hosts had pre-empted the negotiations with their draft proposal, prepared before the two-week conference began.
The Danish draft proposal circulating at the 192-nation conference chips away at the wall between what developed and developing nations can be expected to do to reduce emissions of greenhouse gases. The Danish proposal would allow rich countries to cut fewer emissions while poorer nations would face tougher limits on greenhouse gases and more conditions on money available to adapt.
