Scientists Call for Overhaul of IPCC Climate Panel

When a United Nations panel of experts released a report last week affirming that man-made climate change is a scientific certainty, skeptics of global warming were noisily trying to discredit the panel. In the process, they drowned out the critiques of a far different group. 

A broad array of leading climate scientists and policy specialists were also criticizing the panel for the exact opposite reason: They believe the main conclusions of the Intergovernmental Panel on Climate Change (IPCC) may be too general and too conservative to convey a clear message about the grave threat of warming and to inform policies to address local climate change issues. They say that after 25 years it might be time to overhaul the organization and refocus its research priorities.
