"Two years ago, an international scientific panel seized worldwide attention by reporting that human activity was warming the planet in ways that could greatly disrupt human affairs and nature.
The work of the group, the Intergovernmental Panel on Climate Change, shared the 2007 Nobel Peace Prize with former Vice President Al Gore. After two decades of delivering climate reports to the world without fanfare, it suddenly had a wide following.
But as the panel gears up for its next climate review, many specialists in climate science and policy, both inside and out of the network, are warning that it could quickly lose relevance unless it adjusts its methods and focus.
Although the panel, founded in 1988 and operating under the United Nations’ auspices, has garnered awards and acclaim, there is scant evidence that nations are acting on its warnings. Emissions of heat-trapping gases have grown. Talks about a new climate treaty remain largely deadlocked."
