July 2010 was the second hottest July in the 32-year history of charting temperatures by satellite, according to preliminary records kept by the Earth System Science Center at the University of Alabama in Huntsville.

The global average temperature was only 0.03 C cooler than the record set in July 1998, said Dr. John Christy, professor of atmospheric science and director of the Earth System Science Center.

The increases over the 20-year average for July were recorded to be:

  • Global composite temperature — Up +0.49 C (about 0.88 degrees Fahrenheit).
  • Northern Hemisphere — Up +0.63 C (about 1.13 degrees Fahrenheit).
  • Southern Hemisphere — Up +0.34 C (about 0.58 degrees Fahrenheit).
  • Tropics — An increase of +0.48 C (about 0.61 degrees Fahrenheit).

Average temperatures for the globe, as well as the northern and southern hemispheres, went up in July despite the continued cooling effects the Pacific Ocean transitioning from the warmer waters of what’s known as the El Nino cycle to the cooler La Nina Pacific Ocean cycle.

“If you look at how much sea surface temperatures are falling, no one would have predicted this,” Christy said.

UA Huntsville, NOAA and NASA have partnered in a project to record global and regional temperatures. Christy and Dr. Roy Spencer, the principal research scientists  the ESSC, use data gathered by “advanced microwave sounding units on NOAA and NASA satellites” to obtain accurate temperature readings across the planet, even in remote desert, forest and ocean regions where data isn’t available from other sources, according to a UA Huntsville news release.

The release notes that neither scientist receives any research support from oil, coal or industrial companies or organizations, or from any private or special interest groups.

The project is underwritten by federal and state grants or contracts.
