In the LA Times, there was a story on Richard Muller’s invitation to DC to testify to congress about the Berkeley Project, which attempts to reconstruct global dataThe Berkeley Earth Surface Temperature study is led by physicist Richard Muller, a longtime critic of the scientific consensus on climate change, who plans to testify on the effort Thursday before the House Science Committee in the latest of several congressional inquiries on climate science since the GOP majority was seated. Temperature data from tens of thousands of weather stations across the globe, many of which have incomplete records, are “very contentious,” Muller said in an interview. “The skeptics are raising legitimate concerns.”
Muller and many of those who question the temperature data are drawn to the “urban heat island” phenomenon, maintaining that gauges may be registering latent heat from asphalt, concrete and other urban features. Over time, some weather stations that once recorded temperatures in rural areas have been surrounded by cities and suburbs. The Berkeley project is analyzing information from 39,000 stations -five times as many as the other groups, Muller said – and will address the fact that temperature data have been recorded at varying times of day.
The project also will put its calculations on the Internet in a “transparent” way, Muller said. Other scientists, he said, “put homogenized data online. They don’t put up the [software] tools that get you from the raw data to the homogenized data. How do they pick the [weather station] sites? That involves human judgment.”
