How do climate, peace tie in?

OSLO -- Awarding the Nobel Peace Prize to former Vice President Al Gore and the U.N. Intergovernmental Panel on Climate Change widens a definition of peacemaking and will raise pressure for the world to agree a new deal to combat global warming.

"I hope this will enhance further a sense of urgency," said Yvo de Boer, the head of the U.N. Climate Change Secretariat who wants governments to set a 2009 deadline to work out a new long-term plan to fight global warming.

The secretive Nobel Committee, making the first award clearly linking climate change to peace since the prize was set up in 1901, said Friday: "Action is necessary now, before climate change moves beyond man's control."

Broadening a definition of peace, the Nobel Committee said "there may be increased danger of violent conflicts and wars," because of tensions over ever scarcer resources caused by more floods, droughts, desertification and rising seas.

"We face a true planetary emergency," Gore said Friday. Such theories are not universally accepted, especially in the United States.

Stein Toennesson, head of the International Peace Research Institute in Oslo, said climate change might lead to conflicts but "it could just as well lead to more cooperation."

Many experts say creeping desertification, linked to climate change, is an underlying spur to the conflict in Darfur, Sudan, where 200,000 people have died.

"The Nobel Peace Prize Committee has today made it clear that combating climate change is a central peace and security policy for the 21st century," said Achim Steiner, head of the U.N. Environment Program.

The IPCC said this year it was "very likely" or at least 90 percent certain that humanity was to blame for global warming, mainly by burning fossil fuels. And it said time was running short for action that would have moderate costs.

The prize to Gore and the U.N.'s climate panel, which has issued reports this year outlining risks of global warming, partly targets the world's environment ministers who will meet in Bali from Dec. 3-14.

The United Nations and the Group of Eight industrialized countries want them to agree a 2-year negotiating mandate to broaden the Kyoto Protocol, the main plan for curbing warming, to outsiders such as the United States and China.

By coincidence, the Nobel Prize will be handed out in a ceremony in Oslo on Dec. 10 -- and so gives both Gore and Rajendra Pachauri, chairman of the IPCC, a new stage to urge action. Both Pachauri and Gore already were due to visit Bali.

"Now, we have started a small road, a path when it comes to environment," committee chairman Ole Danbolt Mjoes said, noting the prize had been widened to new areas such as human rights over the years.
