Al Gore, CRED, disaster data

Al Gore’s Evolving Message, by Edward John Craig
Planet Gore/NRO, Feb 23, 2009

Via Marc Morano: Andy Revkin at Dot Earth notes that Roger Pielke Jr. has scientific cred. Pielke has shamed the Goracle into pulling the anthropogenic-natural-disasters slide from his global-warming climate-change presentation.

Former Vice President Al Gore is pulling a dramatic slide from his ever-evolving global warming presentation. When Mr. Gore addressed a packed, cheering hall at the annual meeting of the American Association for the Advancement of Science in Chicago earlier this month, his climate slide show contained a startling graph showing a ceiling-high spike in disasters in recent years. The data came from the Center for Research on the Epidemiology of Disasters (also called CRED) at the Catholic University of Louvain in Brussels.

The graph, which was added to his talk last year, came just after a sequence of images of people from Iowa to South Australia struggling with drought, wildfire, flooding and other weather-related calamities. Mr. Gore described the pattern as a
manifestation of human-driven climate change. “This is creating weather-related disasters that are completely unprecedented,” he said. (The preceding link is to a video clip of that portion of the talk; go to 7th minute.)

Now Mr. Gore is dropping the graph, his office said today. Here’s why.

Two days after the talk, Mr. Gore was sharply criticized for using the data to make a point about global warming by Roger A. Pielke, Jr., a political scientist focused on disaster trends and climate policy at the University of Colorado. Mr. Pielke noted that [CRED] stressed in reports that a host of factors unrelated to climate caused the enormous rise in reported disasters (details below).
