But even then the «fraction of the anomaly due to global warming» is somewhat arbitrary because it depends on the chosen baseline for defining the anomaly — is it the average July temperature, or typical previous summer heat waves (however defined), or the average summer temperature, or the average annual temperature?

One reason for this is that «global temperature» varies significantly over the months of the year due to seasonally varying Earth / sun geometry and the greater land mass in the Northern Hemisphere, so that any global average of absolute temperature, not anomalies, will be considerably higher in NH summer than SH summer, and this will be true even in an unchanging climate.

The metric used by IPCC in all its reports for past and projected future «global warming» has been the «globally and annually averaged land and sea surface temperature anomaly» (as reported by HadCRUT3).

I am still waiting for word on what the global temperature anomaly for the month was, but I suspect it will be fairly close to normal, which means that on average the temperature of the Earth will come in at ~ 12.0 °C which is 4 °C colder than it will be in 6 months from now, but because of how they talk about temperature, I will be the only one pointing out the difference between the actual temperature and the anomaly temperature.

Then using an estimate of 14.0 C for the global temperature average of the 20th century, 12 - month absolute temperatures were calculated from the calculated 12 - month average anomalies.

Despite these reclassifications, the general conclusions are similar from previous work: (1) global temperature anomalies for each phase (El Niño, La Niña, and neutral) have been increasing over time and (2) on average, global temperatures during El Niño years are higher than neutral years, which in turn, are higher than La Niña years.

Roger — I would argue that temperatures aren't averaged, and consequently average temperature is not used to compute global delta T. Rather, what are averaged are grid - based temperature anomalies, so that it is change (delta T) in each region from one year to the next that is used for averaging rather than global average temperatures.

The more I thought about the practice of subtracting the Nino 3.4 variations from the global average temperature anomalies, the more questions came up for me.

So, for example, HadCRU and GISS each provide a climatological datum of mean global temperature for a single year and present it as a difference (i.e. an anomaly) from the average mean global temperature of a 30 year period.
