It’s official, although not necessarily a surprise. The average temperature across the contiguous United States for the first six months of this year has been the warmest on record — and by a considerable sum — dating back to 1895, according to a monthly report released Monday by NOAA’s National Climatic Data Center.

The average 2012 temperature through June was 57.4 degrees Fahrenheit — 4.5 degrees higher than the long-term average for the same period. That’s 1.5 degrees warmer on average than the second hottest temperatures recorded, in 2006, said Jake Crouch, a climate scientist at the data center.
