RSS: Sept 09 was very warm

According to RSS's calculations, Sept 09 was the warmest month (relative to it average) since Jan 07, which set a record for the warmest month of all time.

In fact, it was the warmest September since 1998, the year with the super El Nino. Given that the Southern Oscillation Index is essentially flat right now, it makes you wonder -- why is Sept 09 so warm if El Nino is so weak, unless it's from a generally upward trend in decadal temperatures?

    Also there's the solar minimum too.

    I think skeptics would be better off downplaying the solar minimum and overplaying the recent el nino if they want to claim warming has stopped.

    But they are doing the opposite!
