Officials: Past 12 months warmest ever for U.S.
The mainland United States, which was largely recovering Monday from a near-nationwide heat wave, has experienced the warmest 12-month period since record-keeping began in 1895, the National Oceanic and Atmospheric Administration said Monday.
High temperatures during June also contributed to a record-warm first half of the year, the agency said in its monthly analysis. The heat during the last half of June broke or tied 170 all-time high temperature records in cities across the lower 48 states.
“Temperatures in South Carolina (113 degrees) and Georgia (112 degrees) are currently under review by the U.S. State Climate Extremes Committee as possible all-time statewide temperature records,” NOAA said.
The average temperature for the mainland in June was 71.2 degrees — two degrees above the 20th-century average and the 14th warmest June on record.
