Five US cities – Boston, Providence, R.I.; Hartford, Conn.; Concord, N.H.; and Caribou, Maine – broke temperature records in 2010, a new report has found.
Five cities in the northeastern United States broke their own record of all-time hottest year in 2010, according to a report out Wednesday (Jan. 5).
For Boston, 2010 had the highest average temperature since records began being kept in 1872, when The Great Fire almost wiped the city off the map. The other four cities were: Providence, R.I.; Hartford, Conn.; Concord, N.H.; and Caribou, Maine.
The researchers looked at temperature data collected by the National Oceanic and Atmospheric Administration (NOAA) at various sites in cities across the northeastern United States. The yearly number for each city is the average of daily temperatures, which themselves are an average of the day's minimum and maximum temperature. [Infographic: Hot Spots in 2010]
