The experiment is over, ENSO neutral conditions no longer exist.
As you recall this summer presented a rare opportunity for seeing what the global tempersture was under neutral natural variability conditions: EL Nino, solar irradiance and volcanic activity were all neutral for about 4 months. So we could see how much the planet had warmed since the IPCC model baseline 1990 without the complicating factors of natural variation and see how that compared to the model projection of 0.18C per decade for scenario A1B1.

The ONI [3 month running mean of Nino 3.4 region] this summer averaged 0.0C for J,J,August (neutral conditions) and -0.2C for J,A,September ( a hair cooler than neutral conditions).

The sun also neutral....
The global average lower troposphere temperature averages
JJA = 0.293 C
JAS = 0.280 C
or 0.3C for the summer, just what I predicted by using the IPCC global model predictions from back around 2000, using their 0.18C per decade projection from circa 1990 which averaged -0.05C (sans Mt Pinituba months).

ADDING TWO DECADES OF AGW WARMING (+0.18C PER DECADE PER IPCC A1B) TO THE CIRCA 1991 TEMPERATURE (-0.05C) PRODUCES ABOUT +0.3C NORM FOR THIS SUMMER. IT WILL BE FUN TO SEE IF IT WORKS OUT.
The math.... (0.0177C/year)(21yrs) + -0.05C = 0.32C, => 0.3C.
