The GISS finally releases their June temperature

You need to realize that an El Nino is not a weather event. Weather events don't go on for months at a time. It is a climate variation.

Calling it weather is just more dishonesty.

It is a weather event or pattern in that it is a know set of conditions that repeats.
The warming from an El Nino is many times greater that that of AGW, but the El Nino, being weather event does go away.
Even the USGS calls El Ninos a weather pattern.
El Niño Home Page - USGS
Although the U.S. Geological Survey doesn’t directly study or forecast the weather (our sister agency, NOAA, and its National Weather Service do), the USGS studies and documents the effects and impacts of long-term climate changes and weather phenomena across the U.S. and globally. In particular, the USGS monitors streamflow, floods, landslides, erosion, sea-level rise, and many other earth processes that affect communities and that are often affected by El Niño weather patterns.

These particular changes don't fit the 'cooling the past' narrative: The adjustments to the first 18 years of that period made them an average of 4.17 hundredths of a degree warmer, whereas the adjustments to the last 18 years made them only 3.9 hundredths of a degree warmer. In other words, these adjustments represent a decrease in the warming trend over that period.

To me it is just data, fitting a narrative, is not the goal.
I had read from perhaps biased sources, that the GISS June 2015 adjustment integrated the 1978 to 1998 rapid temperature
increase over a broader period, reducing the obvious nature of the pause.

So you have a narrative , and to make it fit with your goal , you stick with the unnamed 'biased sources' for data.

Because when you hear the credible sources (The head of GISS, NASA,NOAA,NAS,etc), they don't tell you what you want to hear.

Have I got that right?

The "adjustment" to the GISS data set in 2015 was fairly significant, adding .08C to the recent record.
When the 124 year measurement was .87 C, the "adjustment" increased it to .95 C, over a 9 % increase.

Sure. Just make sure you see the ones at (insert favorite denier blog here), because the actual data which was posted shows that the adjustment has trended toward adjusting historical temps upward.

In some years, or over some periods. Over the whole record, the net effect of adjustments increases the warming trend from the uncorrected data substantially, mostly due to time of observation and station history adjustments. From Hansen et al's 2010 update to the GISS record (link available from the GISS page Longview linked earlier):

The points which some 'sceptics' seem to miss are that A) raw data from something as vast as global temperature trends over many decades is pretty much guaranteed to have many problems which need correcting and B) that applies just as much to the atmospheric temperature records of UAH and RSS as it does to the surface records.

True. But if I recall correctly, the baseline periods used to calculate temperature anomalies were only very slightly changed, which is really the important thing.

If I recall, there was a paper coauthored by Gavin Schmidt (head of GISS) that had further adjustments that tended to trend warmer historically. It was out the last few years- when I get back to a desktop, I'll see if I can dig it up.
