When the effects are calculated in a standard climate model, the result is a reduction in average temperature of 0.00005oC (one twenty-thousandth of a degree Celsius, or one ten-thousandth of a degree Fahrenheit).

It's also worth chucking into the mix that the global average temperature variation between even the strongest El Nino event and the next ordinary year is a fraction of a degree Celsius - certainly less than the rise of about 0.6C that we've seen since the beginning of the study period, in 1950.
