Summer was hot, despite Sun's deep low.
In 2008, the Sun reached the lowest point of its 11 year cycle, and this time it was a deep low, the Sun was the coolest it has ever been since 1913. In 2009 and the following 4-5 years (half of its cycle), its temperature will rise. We can expect more 100+ summer temperatures.
According to NOAA, August and September 2009 were the second hottest on record, despite the Sun's deep low just ending.
