Update: GISTEMP indicates that September 2008 - with the anomaly of 0.49 °C - was 0.01 °C cooler than August 2008. HadCRUT3 says the same thing: September 2008 was the coldest September in this century so far.RSS MSU and UAH MSU have released their September data about the temperature.
Off-topic: In the latest episode of The Big Bang Theory, The Barbarian Sublimation, Penny revealed some sad aspects of her life to Sheldon who transformed Penny into a multi-user online game addict (Age of Conan). ;-) Incidentally, the two actors (Penny and Sheldon) are rumored to date in the real life: Kaley Cuoco prefers a copy over the original haha.According to RSS, the month with its 0.211 °C anomaly was 0.07 °C warmer than the previous month. UAH, with a 0.16 °C anomaly, makes it 0.17 °C warmer. Let's focus on RSS. Despite the month-on-month warming, September 2008 was the coolest September in this century so far. The running average of the last 12 months, 0.047 °C according to UAH, was also the coolest one for all months in this century so far.
Many places such as Ireland have witnessed the coldest September in 14 years.

A weak tropical storm, Marco, sits above the Eastern coast of Mexico and will evaporate very soon. The Arctic sea ice area is 2 million sq. km below the normal for this season which is still 0.5 million sq. km more than a year ago. The Antarctic sea ice area is at 14.5 million sq. km, near the normal figure of 15 million sq. km for early October but less than a year ago when the anomaly was highly positive.
