Climate change delegates hash out measures to stem rise in global temperatures

Nations at a global climate change conference mapped out measures to combat global warming and neared agreement on including nuclear energy as a way to cut emissions of greenhouse gases, delegates and observers said.
A report from the Intergovernmental Panel on Climate Change _ the United Nations network of 2,000 scientists _ on how the world should cope with global warming was being debated in secret this week by delegates from more than 120 governments.
A final version expected by Friday will warn of catastrophe unless the world acts quickly to stem climate change.
The report will urge countries to deploy an array of measures _ including energy-efficient technologies, a shift away from coal, and agricultural reforms _ to keep world temperatures from rising more than 2 degrees C (3.6 degrees F), thereby limiting the impact of global warming.
Delegates on Wednesday focused on different categories of energy use and ways to cut emissions as they went through a draft of the report summary, and were working into the night so negotiations could be wrapped up on Thursday.
One contentious issue has been whether and how to refer to nuclear power in the final summary. The United States, for instance, is pushing for a strong reference to atomic energy as a clean source of electricity, while environmentalists are arguing that other ways of cutting carbon emissions _ such as renewable energy sources _ should get priority.
Many environmentalists consider atomic energy too dangerous and costly to be a serious means of cutting greenhouse gases. "We don't believe that nuclear is a solution," said Stephan Singer of the World Wildlife Fund
Two previous IPCC reports this year painted a dire picture of a future in which unabated greenhouse gas emissions could drive global temperatures up as much as 6 degrees C (11 degrees F) by 2100. Even a 2 degree C rise could subject up to 2 billion people, mostly in the developing world, to water shortages by 2050 and threaten extinction for 20 percent to 30 percent of the world's species, the IPCC said.
One of the reports concluded that global warming could increase the number of hungry in the world in 2080 by between 140 million and 1 billion by contributing to widespread droughts and flooding. Diseases such as malaria, diarrhea and dengue fever could spread as temperatures rise and weather becomes increasingly erratic, affecting the poorest of the world's poor.
Delegates interviewed said they were optimistic that the "core messages" of the draft report would survive negotiations, noting that wording had already been reached that concludes global warming will rise dramatically without any action.
