I wrote here about the temperature records at the weather station nearest my home. (The station is about two miles from my home -- as the crow flies.) The average temperature for 2007 has just been posted, leading me to make some further observations:
- It remains the case (as I reported before) that half of the eighteen warmest years on record (years with an average temperature more than one standard deviation above the mean for 1854-2007) occurred before 1980.
- Every year from 2000 through 2007 (but one) has been cooler than the two very hot years of 1998-99. Moreover, the trend is downward.
- The cumulative, five-year-average temperature peaked in 2002. That peak was only 0.54 degree higher than the previous peak, which occurred in 1935.
