Philip Gentry has provided us the June 2012 lower tropospheric temperature analysis. The report is below and the figures he provided are above.

Notes on data released July 6, 2012:
Compared to global seasonal norms, June 2012 was the third warmest in the 34-year satellite record, according to Dr. John Christy, a professor of atmospheric science and director of the Earth System Science Center at The University of Alabama in Huntsville. It was the second warmest June in the Northern Hemisphere, second only to June 1998, during the El Nino Pacific Ocean warming event “of the century.” It was the seventh warmest June in the Southern Hemisphere and the 11th warmest in the tropics, where rising temperatures may hint at the approach of another El Nino.
Compared to seasonal norms, the “warmest” place on Earth in June was in central Russia south of the Taz River. Temperatures there averaged as much as 6.25 C (about 11.25 degrees F) warmer than seasonal norms. The coolest spot was near the South Pole, where winter temperatures for the month averaged 4.09 C (about 7.36 degrees F) cooler than June norms.

As part of an ongoing joint project between UAHuntsville, NOAA and NASA, John Christy, a professor of atmospheric science and director of the Earth System Science Center (ESSC) at The University of Alabama in Huntsville, and Dr. Roy Spencer, an ESSC principal scientist, use data gathered by advanced microwave sounding units on NOAA and NASA satellites to get accurate temperature readings for almost all regions of the Earth. This includes remote desert, ocean and rain forest areas where reliable climate data are not otherwise available.
The satellite-based instruments measure the temperature of the atmosphere from the surface up to an altitude of about eight kilometers above sea level. Once the monthly temperature data is collected and processed, it is placed in a “public” computer file for immediate access by atmospheric scientists in the U.S. and abroad.
Neither Christy nor Spencer receives any research support or funding from oil, coal or industrial companies or organizations, or from any private or special interest groups. All of their climate research funding comes from federal and state grants or contracts.
