Despite the fact that 2014 will likely be classified as Earth's warmest year in history in an announcement due from NOAA on January 16, the year was not a notable one for all-time national heat records. Two nations tied or set all-time records for their hottest temperature in recorded history in 2014, and three territories set all-time cold records. For comparison, five countries and three territories set all-time hottest temperature records in 2013; the most all-time national heat records in a year was twenty nations and one territory in 2010. Since 2010, 45 nations or territories (out of a total of 235) have set or tied all-time heat records, and four have set all-time cold temperature records.
Since each of those years ranked as one of the top twelve warmest years in Earth's recorded history (with 2010 being the warmest year on record), this sort of disparity in national heat and cold records is to be expected. Most nations do not maintain official databases of extreme temperature records, so the national temperature records reported here are in many cases not official. I use as my source for international weather records Maximiliano Herrera, one of the world's top climatologists, who maintains a comprehensive list of extreme temperature records for every nation in the world on his website

Burt maintains a database of these national heat and cold records for 235 nations and territories on wunderground.com's extremes page
