U.S. Just Had Warmest Spring On Record

The year 2012 is, thus far the warmest year ever.

The average temperature for the contiguous 48 states for meteorological spring, which runs from March through May, was 57.1 degrees F (13.9 C), 5.2 degrees (2.9 C) above the 20th century long-term average and 2 degrees F (1.1 C) warmer than the previous warmest spring in 1910…

The global monthly mean level of atmospheric carbon dioxide was about 394 ppm in April, compared to 336 ppm in 1979, pre-industrial levels of about 278 ppm and ice age levels of about 185 ppm.
