    Well, only if you intentionally ignore all of the data you have.
    Land based station average temps since 1980:
    YEAR MAXTEMP
    1998 63.80498
    1999 63.78164
    2006 63.73651
    2007 63.67106

    But if you use the measured surface temp data all the way back to 1940, the order is a little different:
    YEAR MAXTEMP

    1971 49.46261
    1969 49.27156

    Just another example of how the subject is being slanted to frame the argument. And unless you actually take the time to get the raw data and process it yourself, you're subject to intentional deception.
    Note: I've limited the data included in the averages to stations (18,186 of them) that provided at least 240 days of data for at least 60 years in the date range of 1940 to 2011. This prevents stations that provided limited data from biasing the results one way or another.

      the hottest 12-month period ever recorded was from June 2009 to May 2010

    Not according to the actual measured surface station temperatures.

    Global Stations:

    Global Daily 1Yr Running Avg
    US Daily 1Yr Running Avg

    Never is a long time.
