Poor urge deep climate cuts

BARCELONA, Spain (Reuters) - Developing countries said on Wednesday they risked "total destruction" unless the rich stepped up the fight against climate change to a level that even the United Nations says is out of reach.

The top U.S. climate diplomat Todd Stern blamed a "17-year divide" between rich and poor nations for slow progress at the U.N. talks meant to agree a global climate deal in Copenhagen in December, and slammed "debating society" pranks.

Keeping up pressure in Barcelona, the final preparatory session for the December meeting, the poor said that even the most ambitious offers by the European Union, tougher than most nations, were far too weak for a new U.N. climate pact.

"The result of that is to condemn developing countries to a total destruction of their livelihoods, their economies. Their land, their forests will all be destroyed. And for what purpose?" said Lumumba Stanislaus Di-Aping of Sudan, chair of the Group of 77 and China, representing poor nations.

"Anything south of 40 (percent) means that Africa's population, Africa's land mass is offered destruction," he told a news conference.

Developing countries at the Barcelona talks insisted that rich nations should cut greenhouse gas emissions by at least 40 percent below 1990 levels by 2020 -- far more than on offer.

But even the United Nations said that would involve too wrenching a shift. African nations resumed negotiations in Barcelona on Tuesday after a one-day partial boycott following agreement on more focus on cuts by the rich.

"I think to get to minus 40 is too heavy a lift," Yvo de Boer, head of the U.N. Climate Change Secretariat, told Reuters. Such a shift would require "going back to the drawing board" and would economically "come at a huge cost," he said.
