From the Jerusalem Post:
The year 2010 was the hottest by a large margin since records began being kept in Israel, with temperatures two to three degrees hotter than the average, according to the Israel Meteorological Service’s year-end summary. What’s more, temperatures were one to one-and-a-half degrees Celsius higher than the next hottest year, a striking statistic, according to the IMS. Most years, the average temperatures fall within 0.1- .0.3 degrees of other years. For example, the average temperature for Jerusalem between 1981 and 2000 was 17.5 [63.5 F] degrees. In 2010, the average temperature was 20.3 [68.5] and during the next hottest year, 1998, it was 18.7 [65.6 F]. […] The IMS also tracks rainfall, and while this past year was one of the driest, there have been drier years. However, 2010 was unique in that it had the least amount of days of rain at many of the monitoring stations. For example, in Jerusalem and Haifa, the fewest number of rain days were recorded in the past 80 years.
