did have some debatable aspects to do with the calculations and the lads quickly picked up my gaffe in saying the pre-1976 / GPCS temperature data did have a downward trend overlooking the fact that M&Q used data from 1951 not the whole data from the beginning of the La Nina period in 1942; even so, despite there being a slight upward trend from 1951 -1975 [the year before the GPCS], the average temperature for this period is -0.194 C below the anomaly base period of 1961 - 1990; the average temperature from 1981 — 2005 is +0.315 C above the base period average; the average in the period between 1976 — 1980, the period of the GPCS, is 29.2 C above the base period average; accusations of cherry picking and the artificiality of using seperate regressions for the pre and post GPCS period were levied; a Chow Test needs to be done;

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.

I'm very convinced that the physical process of global warming is continuing, which appears as a statistically significant increase of the global surface and tropospheric temperature anomaly over a time scale of about 20 years and longer and also as trends in other climate variables (e.g., global ocean heat content increase, Arctic and Antarctic ice decrease, mountain glacier decrease on average and others), and I don't see any scientific evidence according to which this trend has been broken, recently.

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.

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.

If we are in a long - term warming trend that will last hundreds of years more, I'm afraid debates about anomaly charts, and whether or not a year set a new record, are mental masturbation — some decades will have warming, other decades will have cooling, but record high average temperatures will occur regularly or irregularly while the Modern Warming temperature uptrend is in progress. . .
