Continued...Randy Russell, an assistant professor in the Department of Physical Sciences and Chemistry at AUM, said the Environment America report was not done in a way that allowed one to draw any concrete conclusions.
"When you look at climate, it's an average over 30 years," he said. "You wouldn't necessarily have an indication of change if the average is different in one year."
Russell said scientists look at temperatures around the globe and how they've changed from one series of decades to another.
"What you really need to do would be not to compare an individual year but see how long-term changes occur over time," he said. Then you can see a trend."
The Environment America report also compares government temperature data for the years 2000-2007 with the historical average temperature for the preceding 30 years, 1971-2000.
Russell said 2000-2007 is not an adequate sample size.
