Sea surface temperatures in the Gulf are now 3 degrees Fahrenheit warmer than the pre-1970 average, said Kevin Trenberth, distinguished senior scientist at the National Center for Atmospheric Research in Boulder, Colorado.

“Two degrees of that can be attributed to natural variability while one degree Fahrenheit is associated with climate change,” Trenberth said in an interview today.

Hayes, Schneider and Thomas Schwein, deputy director of the weather service’s central region, who was also on yesterday’s conference call, weren’t ready to attribute the outbreaks to climate change.
